It’s Not Too Late to Apply a Wheat Fungicide

Many wheat growing geographies in Canada  have received substantial amounts of rain this spring, in addition to the challenges of preparing seed beds and planting, excessive rainfall can also fuel disease. 

Given these conditions, and if they match in your area, this could be the right time to apply fungicide to wheat. Studies (1) show that protecting the flag leaf of wheat, triticale, and oats from disease can assure 70 percent or higher of the crops yield potential. Plan to protect yields with a treatment when conditions align for the best chances to protect your crop from a likely pressure.

In an anticipated high disease pressure year, consider applying a protective fungicide treatment to wheat. It is too late to make a preventative application, once disease pressure and damage is already visible within a field.

Types of fungicide treatment

A fungicide application  helps protect further damage to the plant and as a result can greatly impact yield. There are many types of wheat and small grain fungicides. Those fungicides that contain a strobilurin, such as azoxystrobin, (Group 11) or a triazole, such as triticonazole, (Group 3) are common choices for wheat growers. A combination of both Group 11 and Group 3 fungicides are commonly used as well.

Products that contain  strobilurin should not be applied past anthesis as it can increase the DON level of grain.  Prothio(125.00) + Teb(125.00) Value Pick

is an excellent option to apply after flowering.  One of the major advantages of prothio - teb is the product is both a contact and systemic fungicide so as result the product has great curative and preventative properties.

Always scout early for leaf diseases, FBN® has great fungicide options from flag leaf to flowering stage of development.
