Question: When To Spray Wheat For Weeds?

Ultimate guide to spring weed control in winter wheat

To control weeds in wheat fields, a variety of products are available, depending on the weed profile and application time. If grass weeds are the primary target, Atlantis OD (mesosulfuron iodosulfur) is a good option in January. Herbicide performance is dependent on good application conditions. Contact acting herbicides require active growth in the weed and fairly still, dry weather.

Crop management

Early tillering and early nitrogen can help improve crop competitiveness in the spring, and re-drilling with a spring crop is also an option if crops are in poor condition.

Patch management

Weeds are often concentrated in patches, which serve as a jumping off point for infestations to spread across the field. Spraying off patches at any stage of the season before seed sheds is a good way to get weeds under control, so it’s worth waiting until later in the spring.

When should I start spraying for weeds?

The best time to spray the weed killer is in the spring or fall, because we want to do it when the weather is warm, but not too hot or too cold, because the liquid evaporates or freezes. Spray the weed killer in early spring, then another application eight weeks later.

We recommend that 2,4-D not be applied to wheat until it has been well-tilled in the spring, as doing so delays tillering, causes general stunting, and can result in significant yield loss. If spraying before wheat has been well-tilled, MCPA would be preferred over 2,4-D.
