Zinc deficiency in Australia is one of the most common micronutrient deficiencies in crops. Zinc deficiencies can occur on a wide range of soils, from heavy alkaline clay soils to light sandy acidic soils.  In crops, zinc is vital for the formation of chlorophyll and carbohydrates. It plays an important role in the movement of water in plants, aiding in root development and starch formation. Zinc is also essential in aiding the production of growth hormones such as Auxins.  The total amount of zinc in your soil can be directly related to the parent material, for example,  basalt soils can contain high levels of zinc, whereas sandy soils can be low in zinc. Although zinc in organic matter is fairly immobile and very little is leached from the soil, it is often not in a readily available form in the soil. There are many factors that can play a key role in the availability of zinc for plant uptake, such as: Organic matter - Zinc can interact with soil organic matter by forming both insoluble and soluble zinc complexes. It can be mineralised and made available to plants from decomposing organic matter.  The amount of chelating agents in the soil have a direct impact on the movement of Zinc. Chelating agents increase the solubility of zinc from the soil and aid its movement through to the roots of the plants. Climatic conditions can also play a role in zinc availability. A wet winter-spring season, like the one we are experiencing in Australia, can result in zinc deficiency in plants, this is a result of reduced microbiological activity. Microbiological activity is important to assist in releasing zinc from organic matter. Because of this waterlogging can tend to increase zinc deficiency. High levels of available iron can adversely affect the plants ability to take up zinc.  The incorrect application of phosphorus fertiliser may induce zinc deficiency, by affecting the physiological availability of zinc in plant tissues. It has been found that Vesicular arbuscular mycorrhiza (VAM) colonisation of plant roots is reduced in crops growing in soils high in phosphorus. That is why it is really important to know your soils and apply the correct fertiliser types and rates.  High water tables or soil compaction can affect plant root development. This can directly affect the dispersion of zinc in the soil, leading to zinc deficiency. VAM is a beneficial fungi which infects the roots of most crops (except canola). The mycelium (fungal threads) assist the plants ability to uptake immobile nutrients such as phosphorus and zinc, It does this by increasing the root surface area. VAM relies on plants for survival. Fallowing land for a long period, e.g. 12 months, or growing non-host crops (canola), can cause populations to decline, thus increasing the risk of zinc deficiency.  Some symptoms of zinc deficiency are: Brown or yellow patches on the new growth Patchy appearance of the crop Brown necrotic spots on the leaves Poor seed set – young tillers may die before setting seed Poor yield/low protein Zinc toxicity is uncommon, and is more likely to occur in acid soils. High levels of zinc can inhibit a plant's ability to uptake P and Fe.  Zinc as a foliar spray should be applied in small amounts, more regularly. Early in the morning or early evening to reduce evaporation and maximise the intake of zinc into the plant. Best results occur when applied before symptoms of deficiency are noticeable.  is a fully chelated form of zinc, making it both more efficient and effective to use.

As you start to think about using fungicide and insecticide applications this year to combat disease and pests, you’ll want to consider the best ways to get the most out of your application. The last thing you want is yield loss.  Let’s look at the 7 things to know before applying insecticides and fungicides:  1. Know your heat Insect development can be tied to growing degree days (GDD). Growing degree days are a measurement of heat accumulation over time.(1) This is helpful in years where days are hotter than previous years and result in an acceleration of insect pressure and more opportunities for pests to affect yield potential by causing damage to roots and foliage. The GDD for 1st generation adult bean leaf beetles are 1,212 degree days.(2) Knowing the degree days can help develop increased awareness and scouting practices as your farm gets closer to these critical GDD. Did you know that you can see growing degree units by uploading your and unlocking this feature on your FBN® account?  2. Scouting for Confidence Increase your confidence in making timely fungicide and insecticide applications with a quality crop scouting program. Typical crop scouting of walking fields every 7 days will help to see patterns of increased pest or disease pressure. Knowing the economic threshold of specific pests can build confidence in when the time is right to make an insecticide application. 3. Curative or Preventive? Fungicides can be segmented into two camps. Curative or Preventive. Preventive activity happens when the fungicide is present in the leaf tissue but before initial infection occurs. Applications with a Group 11 Fungicide such as can help create a protective barrier before plant diseases are present.  A curative fungicide stops the early growth of the fungal pathogen after infection, the first step of the disease cycle, has occurred. Most curative fungicides are also preventive if applied prior to infection. Despite their name, curative fungicides will NOT cure a plant of the disease. They are not effective against advanced disease cycles. A Group 3 fungicide such as   is considered to be a curative fungicide. and can be tank mixed together to provide a one tank mix solution that's both preventive and curative. 4. Inspect what you expect Do you know how much yield potential you saved from yield robbing pests and diseases this year? Uploading your to your account will help you inspect and overlay many features to better understand crop performance. 5. The right time is the best time The performance and benefits of a fungicide application such as and are optimized at ideal times in crop cycle. Soybeans for example would be in the R3 stage to get the most benefit. (3)  Consider adding   to your fungicide application. Insect feeding creates an entry point for fungal diseases to spread, so if you’ve got bugs, hammer them at the same time by adding an insecticide to your tank mix and keep them from spreading into other fields. 6. Optimize your Tank Mix Make the most of your fungicide and insecticide applications by using adjuvants and crop nutrition products. Adjuvants help increase performance of the product through multiple functions. Insecticides need to be applied on contact while the key component of fungicides is to be absorbed into the plant.

With La Niña in full swing in Australia for the second year, the 2022 season has seen an incredible amount of rainfall across Australia. In April alone, our rainfall was 27% above average as a whole, putting much of Australia into the 10th decile for rainfall.  In a wet season it is really important to keep an eye on our crops' nutrition program. Many of the micronutrients our crops require can be easily leached in wet years. This can result in stunted crops, lower yields or lower protein and oil percentages in crops.  Over the coming weeks we will have a look at these micronutrients, their roles within the plant, and the benefits of proactive application. Boron  Boron is a micronutrient that plants require for healthy cell wall production, it plays an important part in healthy pollination & fruit/seed development. Boron is also instrumental in the translocation of sugars and carbohydrates within the plant.  Along with other micronutrients such as zinc, copper and manganese, it is important to be proactive when applying Boron. Unfortunately, once a deficiency is noticeable, yield has already been affected. For best results it is recommended to apply a small amount, often.  Some indications of Boron deficiency in crops include: Yellowing and death of growing points (Chlorosis) Thickening and cracking of stems (Distortion) Root development anomalies Dropping of buds Discoloration and the crinkling of leaves. As Boron is stored in soil organic matter, its availability will fluctuate according to microbial activity. Boron becomes available as organic matter decomposes. As a result, it can be easily leached, particularly during a wet season.  Calcium, potassium, and nitrogen concentrations in both the soil and plant can affect boron availability and plant function, the calcium:boron (Ca:B) ratio relationship being the most important. Therefore, soils high in calcium will require more boron than soils low in calcium.  As Boron requirements are low it is best to check your crop requirements. Doing a soil test or tissue test is the best way to find out how much Boron is readily available. Higher rates of Boron may be required in heavy clay soils, or soils that have a higher water pH/calcium content.  Boron toxicity is a greater risk on low calcium-content soils. Some symptoms of Boron Toxicity may include: Leaf tip yellowing Leaf necrosis and drop - beginning in the leaf tip Brown & stunted root tips It is best to apply foliar B either in the early morning or evening, when the evaporation rate is low. This will maximise the length of time that the leaves will remain damp, allowing the plant to absorb the most Boron.  is compatible with a wide range of agricultural herbicides and pesticides. Check the Compatibility Guide as a reference. Always do a small jar test before preparing a full tank mix.

Every season crops are planted with hopes of reaching their genetic yield potential. Nearly every year, plants struggle to reach this potential due to many external factors outside of a grower’s control. Growers do have control of supplementing their crops with products to help support plant health that ultimately can help minimize these yield robbing events. FBN® has a quality lineup of crop nutrition products that are made to help support plants throughout the growing season.   Here are 7 ways crop nutrition products can prevent yield loss. 1. Soil Nutrient Efficiency Nutrients and fertilizers applied alone can be tied up in the soil and unavailable to be utilized by plants. Use to improve nutrient  availability through the growing season to prevent any tie up or losses. is a micronized, humate-based source of stable soil carbon that requires less product at a lower rate than standard humic and fulvic products. It works faster to efficiently store and deliver soil nutrients and fertilizers, as well as help increase water utilization. tank mixes well with most fertilizers (A jar test is recommended).  32oz/acre or 1 qt/40 gal Pairs well with normal soil applied fertilizer applications. 2. Safe, Efficient Foliar Nitrogen Source In-season plants can become deficient in nitrogen. A program seeking to address this deficiency and to maximize yield will want to use to supplement these nitrogen deficiencies. is a nitrogen source complexed with micronized, humate-based source of stable carbon that helps efficiently deliver nitrogen into the plant tissue. : 32oz - 128 oz /acre  Do not apply concentrated, see label for dilution instructions Early vegetative through to late reproductive. 3. Root Growth & Nutrient Acquisition Root growth is critical for acquiring nutrients and water uptake. Enhance this root growth with . is a soy protein-based peptide complex that contains a lateral root promoting peptide that signals root growth when foliar is applied as well as allowing the plant to more efficiently uptake soil nutrients.  : 16 oz /acre Early vegetative through to late reproductive. 4. Nitrogen Assimilation Once the plant is up and growing it needs to expend energy to make use of applied Nitrogen and assimilate it into the plant in the form of chlorophyll, amino acids and,eventually, into proteins. contains the 18 essential amino acids in an already usable peptide form to reduce the plant nitrogen demand and supplement in season plant energy. It also contains amino acids essential to Nitrogen assimilation into the plant such as glutamic acid, enabling more efficient nitrogen conversion within the plant. : 16 oz /acre Early vegetative through to late reproductive. Plants need to expend a lot of energy to metabolize different types of herbicides, insecticides and fungicides that can have negative growth and yield impacts.  contains 18 essential amino acids in peptide form that provide supplemental energy to help the plant better metabolize chemicals to minimize any negative damage from chemical stress. is best used as a preventative product prior to stress but may be applied following stress to help the crop bounce back faster.  : 16 oz /acre Early vegetative through to late reproductive. 6. Weather Stress The impact of weather events such as being too hot, too wet, too cold, or too dry requires the plant to generate energy to get through those stressful periods. During this process of diverting energy to combat stress, yield potential is lost. provides the plant with supplemental energy and tools to signal plant health to prevent negative impacts from weather stress such as too much or too little heat or moisture.  : 16 oz /acre Early vegetative through to late reproductive. 7. Address Deficiencies with Nutrient Antagonism Plants need a balanced package of micro and macronutrients to address any potential late season yield limiting deficiencies as well as prevent antagonism by overapplying any single nutrient that may tie others up. contains 4 micronutrients and 6 macronutrients essential for plant growth at a balanced ratio to help address in season needs while preventing this unwanted nutrient antagonism. In doing so, this provides a broad spectrum approach to address any late season yield limiting nutrient deficiencies.  : 32 oz /acre Early vegetative through to late reproductive.

I get asked this question all the time, “When is the right time to buy?” When the chemical is cheap, right? Now it’s not as simple as that  This type of buying behavior takes patience. Love knowing you got the best deal on the day. We all know that over time prices come back. What might be a good deal today, might not be a good deal in 2 months. Buying early has its downfalls, but if you follow a rule of buying when the product is historically a good price, then it doesn’t really matter. You’ll always come out in front. I have had many farmers thank me year on year for helping them save doing just this. Buying out of season Over the years I’ve worked with many farmers who follow this buying pattern.  You have to view chemicals (fertiliser and fuel also) like you do your grain. While most growers check pricing every day, I think you should be checking the price of your chemicals, too.  I am not suggesting you do this for all of them, as I understand there are way too many for that. But I would absolutely keep an eye on the top 10. The savings over 1 shuttle of , or an , we can be talking between $2000 to $3000 a shuttle. For those who use multiples of one product, that adds up pretty quickly!  Well, that’s two products I have highlighted and ‘potential’ savings of $4000 if buying one of each. You see how quickly that adds up. $4000 is a nice little trip to the coast when you’re not sitting on the boom spray or chasing down some sheep on the road because your backpacker left the gate open. It doesn’t matter what size farm you are, it doesn’t matter if you’re buying enviro’s (110L) or buying shuttles (1000L), the buying principles are the same. There are always savings to be had. If you are ever unsure if a price is historically cheap, ask your local chemical rep. Whether it’s your mate in town or an rep. These guys and gals study the form, they’ll know.  When we find some level of normality with chemical prices I think there is huge value in adopting this buying behavior. Every business is looking to shave $’s from their bottom line, I can assure you, this can help to do just that. Getting the best deal on chem and fair market value 1. Use the tools available Load your top 20 chemicals into your ‘favorites’ in your profile. Doing this will ensure you will be able to see every price on one screen and will save you a lot of time. Your local Account Executive or Community Builder can help you do this. 2. Do a ring around or send an email Product Green Red Independent Glyphosate 450 $4.30 $4.20 $4.10 $3.90 Doing the above on a line by line basis will ensure you have the best price on the day and you have just paid fair market value for your product. 3. Review the offer  The best price isn’t always the cheapest. There are always deals that may save you even more than just the price per liter. An example may be 0% finance. This is pretty good and to my knowledge, has never been seen in the industry before.  Learn more To learn more about FBN’s End of Financial Year offerings please visit fbn.com/ourpromos

Optimizing your chemistry program to help maximize yield potential is important and there are many ways growers can do so. Factoring in that canola seed is expensive, maximizing yield is always a high priority.  Here are 5 ways to get the most out of traited canola with non-selective herbicides: 1. Proper application timing and label rate Select the proper labeled rate for the weeds present and their staging. Spray early when weeds are still small enough for good control. Consider a second in crop application if weed pressure is still high after the first application, or a second flush of weeds occurs. 2. Use a surfactant Using a surfactant provides many values such as: Spraying efficacy Drift reduction Water conditioning Anti foaming FBN® has several Utility Modifiers in  our portfolio such as and ® that enhance the performance of  and Advantage  . 3. Importance of multiple modes of action and mixing order Utilizing multiple modes of action is a good stewardship practice to help delay the development of herbicide resistant weeds. offers Canola Acre packs containing a combination of glufosinate and , which takes the guesswork out of tank mixing two different products. You can also enhance weed control by tank mixing and applying multiple products from different herbicide groups. The sequence of tank mixing herbicides is another factor to consider when combining products. Tank mixing order can impact the product suspension and is often a factor that can impact clogging or plugging spray nozzles. Here are two examples of different mixing orders you could utilize: Mix a surfactant in , followed by and finally , Mix , surfactant, glufosinate ammonium, .  4. Insect control  High flea beetle pressure can have large impacts upon yield. When a seed treatment is not controlling 25% feeding damage, has two very effective options to control flea beetles: and 5. Chemistry rotation  Considering the annual chemistry rotation is another tool growers can use to improve weed control throughout the season.  Introducing a rotation of (group 9) with (group 10) and (group 2) along with   (group 1) and (group 4) helps diversify the herbicide groups used on farm.

Post-emergence herbicides are products used to control weeds and other non-desirable vegetation that have grown above ground. There are two types of herbicides that have different effects on the weeds and crop alike: Selective post emergence herbicides are engineered to target the specific weeds they are labeled for. This is helpful in case you over-spray and get the herbicide on plants you do not want to knockdown. is an excellent selective herbicide choice right now. Non-selective post-emergence herbicides will broadly target any plant material it comes into contact with, including knockdown effects on plants that do not carry a tolerance to the herbicide itself. These herbicides, when used at the labeled rates, can control weeds in as little as one application when applications are timed appropriately. MCPA 570 is an effective non-selective post-emergence herbicide you may wish to consider right now. To help you make an informed decision on your post-emergence weed control, we're outlined a few key tips below that may aid your decision making: To evaluate the best post-emergence herbicide options, it is useful to know the resistance status of weeds on an individual property. Commercial resistance testing can confirm the effectiveness (or lack of) of herbicides and establish a baseline of herbicide sensitivity to take the ‘guesswork’ out of decision making. This can be carried out with seed testing at the start of the season or after harvest. Contact post-emergence herbicides should be applied when weeds are actively growing but have not exceeded the height indicated on the label. Contact herbicides are absorbed through the leaves of the plant, so application should be made to a dry leaf with no wet weather forecast for at least two hours. Refer to labels for specific recommendations on rainfastness. Often post-emergent applications contain multiple active ingredients. Follow label instructions to ensure your mix is compatible; if you are unsure, consult a local agronomist or conduct a jar test. Mixing products in the proper order, adding product to the solution slowly, using the right volume of water, and always ensuring agitation occurs before and during spray applications will reduce your likelihood of tank mixing problems. Some liquid post-emergence herbicides will require the use of a surfactant. Surfactants are chemicals that, when mixed with your herbicide, will help the herbicide stick better to the plant, therefore increasing the rate of absorption. FBN’s Trio Wetta 1000 or Trio Chargeup Spray Oil are both available as mixing partners for your in crop herbicide applications (check label requirements).

Weeds are a threat to every farming operation and the number of herbicide resistant weeds continues to grow every year. Creating a strategy to delay the development of resistant weeds is important and should be prioritized on every farm.  As of April 2022, the U.S. has 127 unique herbicide resistant weeds and Canada has 52. (1) There are a number of ways a grower can take a proactive approach to ensure a weed resistance management strategy is implemented on every acre. Let’s get into the weeds with 7 ways to delay the development of herbicide resistant weeds: 1. Use herbicide group numbers to create effective weed selection pressure Each herbicide group number corresponds to a site of action of an active ingredient. When multiple herbicide groups are applied to control a targeted weed, the weed is less likely to escape a spraying, as it must tolerate many different disruptions to its functioning. (2) A general example of this would be a known weed in your area which is resistant to both glyphosate (Group 9) and ALS inhibitor active ingredients (Group 2). Create effective weed selection pressure by applying herbicides from other herbicide groups such as (Group 15) and (Group 14) Download the chart from the United Soybean Board . 2. Know your adjuvant requirements Proper adjuvants increase the efficacy of your burndown and preemergence herbicides. Consult your label to see which adjuvants are required, recommended or may be used. Whether you need a surfactant, a crop oil or a drift inhibitor, take the time to familiarize yourself with the products that can help you get the most out of your herbicide shot, and limit unintended impacts. FBN® offers a robust line of ™ branded adjuvants for all your herbicide, insecticide and fungicide applications. Download the Farmers First Adjuvant Product Guide 3. Include tillage as a weed management tool Utilizing tillage as part of an integrated weed management program with herbicide applications can help reduce seed banks by controlling emerged weeds and burying non-germinated seed. (3)  4. Change planting and fertilizer strategies to enhance the crop canopy Experiment with narrower rows and banding fertilizer to hasten the growth of a crop canopy to shade out competitive weeds. 5. Avoid spreading weed seeds by cleaning equipment before leaving each field Plus, the work that you do to control troublesome weeds in the fence rows adjacent to your fields will also reduce the spread of weeds. 6. Break weed cycles Prevent certain weeds from becoming dominant with crop rotations. This would include row crops, small grains, and cover crops. 7. Herbicide rotation There are many herbicides that are labeled to control the same weed species. Using the same herbicide year after year may initiate resistance, decreasing your ability to control the weeds. Herbicide diversity plays an important role in fighting resistance.

Weeds are a threat to every farming operation and the number of herbicide-resistant weeds continues to grow every year. Creating a strategy to delay the development of resistant weeds is important and should be prioritized on every farm.  As of April 2022, the U.S. has 127 unique herbicide resistant weeds and Canada has 52.¹ There are a number of ways a grower can take a proactive approach to ensure a weed resistance management strategy is implemented on every acre. Let’s get into the weeds with the five ways to delay the development of herbicide resistant weeds: 1. Tank Mixing & Multiple Modes of Action Whenever possible, it’s important to prioritize tank mixing multiple herbicide groups to enhance weed control and mitigate the development of herbicide resistant weeds.  A pre-seed application is a great opportunity to include multiple modes of action from different herbicide groups that target the same weeds.² (group 14) and (group 6) are both excellent herbicide options that tank mix well with pre-seed for most crops. 2. Crop Rotation Diversifying your crop rotation will optimize fertility, and mitigate disease and pest infestation. As well, this will provide you with the opportunity to utilize different selective chemistries for your crops. Consider rotating crops with different seeding and harvest windows to target weeds at optimal points throughout the growing season. Implementing both a diverse crop and chemistry rotation helps to prevent weeds from maturing, setting seed, and becoming a challenge the following year. 3. Chemistry Rotation Throughout the Season It’s a good strategy to use different herbicide groups at different points in the season that target the same weed spectrum. As part of an integrated weed management program, tank mixing products from multiple herbicide groups with every application and focusing on diversifying the annual chemistry rotation is recommended. 4. Effective Herbicide Application Keeping clean fields year over year helps reduce the opportunity for herbicide resistant weeds to develop, set seed, and propagate. When using products, it’s recommended to always use the label rate and directions to help you best achieve clean fields and minimize weed growth. Utilizing best practices regarding boom height, water volume, wind speed, and sprayer speed increase your chances of eliminating herbicide resistant weeds. 5. Maintaining Clean Fields with Multiple Applications Throughout the Season Preemergence Early weed control is recommended as herbicides are typically most effective on small weeds.³ Most product labels do not target later stages of weed development and, as a result, weeds can mature, set seed, and become a challenge to control. (group 4) is an example of a preemergence product with residual control that can be applied prior to planting cereals that targets kochia (including group 2 resistant biotypes).   In Crop As a grower, you need to scout your fields to tailor your herbicide post emergence program to maximize and diversify weed control programs. Regional differences in weed pressures and crop mix potentially require more selective herbicide tank mix partners to control all types of weeds in the field.   There are multiple tank mix options that can be customized according to crop and target weed spectrum. For example, tank mixing Steel (group 2 and 4) and MCPA (group 4) are options for an in crop application in cereals. Another potential tank mix is (group 10) with (group 1) and (group 4) for an in crop application in glufosinate tolerant canola.  Post-Harvest Burndown Combining a non-selective herbicide and a selective herbicide in a post-harvest application can be a very effective way to incorporate different herbicide groups and modes of action.  Prioritizing weed control in the fall will help to minimize weed seed development and weed pressure the following year. Always add another effective mode of action like a group 2 or 4 when applying glyphosate.  For example, tank mixing (group 2), 2,4-D (group 4) or  (group 4) with (group 9) for a post-harvest application. Protecting the long-term sustainability of your operation starts with protecting your crops by implementing a robust weed management strategy that incorporates cropping and chemistry diversity.  Shop for Herbicides Through FBN Find the products you need at .
