Hessian Fly Observed In Spring Wheat

Hessian fly was observed in spring wheat plantings at the Langdon REC (Source: Dr. Gautam, LREC). Hessian fly is an occasional insect pest problem of wheat in North Dakota. The injury is caused by the white maggot (larval stage). Larvae feed on plant sap and inject a toxic salivary secretion into the plant which interferes with plant growth. In this case, the infested young spring wheat plants were yellowing, withering and dying. Wheat growth and yield can be reduced. Insecticide seed treatments provide only 2-3 weeks of control, but there is no control of Hessian fly larvae with foliar insecticides. Host plant resistance is the most effective method of Hessian fly pest management. Unfortunately, most wheat cultivars do not have the Hessian fly resistance genes.

Video: Dicamba Returns for Georgia Farmers: What the New EPA Ruling Means for Cotton Growers

After being unavailable in 2024 due to registration issues, dicamba products are returning for Georgia farmers this growing season — but under strict new conditions.

In this report from Tifton, Extension Weed Specialist Stanley Culpepper explains the updated EPA ruling, including new application limits, mandatory training requirements, and the need for a restricted use pesticide license. Among the key changes: a cap of two ½-pound applications per year and the required use of an approved volatility reduction agent with every application.

For Georgia cotton producers, the ruling is significant. According to Taylor Sills with the Georgia Cotton Commission, the vast majority of cotton planted in the state carries the dicamba-tolerant trait — meaning farmers had been paying for technology they couldn’t use.

While environmental groups have expressed concerns over spray drift, Georgia growers have reduced off-target pesticide movement by more than 91% over the past decade. Still, this two-year registration period will come with increased scrutiny, making stewardship and compliance more important than ever.
