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).

Summer & pre-plant spray out is an important part of the grain growing cycle. By now, most growers have harvested the majority of their crops and are looking to take the next steps into summer spraying and pre-planting spray programs to help utilise the upcoming planting of their next crop. There are many factors to consider within this period, those being chemical selection spray timing, quantity of knock down passes and soil fertility to name a few. Managing this time of the cycle is very important in making sure crucial steps are taken to help produce high yields for your next crop. Controlling weeds is a key component in making this process more profitable in the long run. There are a few key points to consider when working through this process. Pre-planting tips Glyphosate is a contact-only herbicide and has no soil or residual activity. In other words, if it doesn’t touch the green tissue of a living plant it is non-effective. This allows you to spray very close to your planting time to help your crop get a jump start on any weeds. The ideal timing for spraying can take up to 2 weeks before planting to achieve really good knockdown results, so the time to act is now.  4 tips for good pre–planting herbicide applications - The information on the herbicide label contains all of the necessary information and identifies what weeds it kills and what the recommended rate is. - Spray when grasses or broadleaf weeds are young and thriving. If the field is tall and overgrown, the results will often be less than desirable. If weeds are already tall and mature, mow first and return a few days later to spray the new re-growth even if it is minimal. - Many times the correct amount of herbicide is used but not enough water is added to thoroughly spray mix (where necessary, get your water tested). - Knowing the size of paddocks you are going to be spraying will help you apply the appropriate amount of solution. To practice and calibrate your sprayer, find a paddock and measure it with a GPS to determine the size. Fill your spray tank with just water and take note of the speed you travel and the amount of water you apply over the known area. This will eliminate guesswork and yield better spray results. Controlling summer weeds Effective weed control can reduce weed numbers in subsequent years and run down the seedbank. Uncontrolled weeds contribute massively to the soil seedbank, creating increased costs of control and future weed burdens. This may limit crop choice and reduce flexibility within your program. Summer weed control can be expensive but is necessary to prevent problems with excessive growth and/or moisture and nitrogen loss from the soil.  When using herbicides Water rates should be kept high (at least 60 litres per hectare). Add a surfactant and/or spraying oil to all post-emergent treatments unless otherwise directed on the label. Do not spray stressed plants. Spray grazing can be effective at high stocking rates. When it's time to spray out Consider these factors before going ahead: Always check for susceptible crops in the area, for example broadleaf crops such as grape vines, cotton, vegetables and pulses, if you are using a broadleaf herbicide. Check sensitive areas such as houses, schools, waterways and riverbanks.  Notify neighbours of your spraying intentions. Planning your post-harvest spray program is key to allowing the best opportunity to produce high yielding crops post planting.
