Control and injury are two of the most critical factors in determining herbicide selection for wild radish control in wheat. Tables 13 and 14 outline the effects of various herbicides on control and potential injury in Georgia wheat production. 2 Percent control as compared to untreated areas. This species is widespread throughout Georgia and the southeast. Therefore, successful ryegrass control can be a vital element in producing wheat in Georgia.
Italian ryegrass is an annual and is spread primarily by seed.
Management practices to reduce seed spread will greatly decrease ryegrass problems. Burning after harvest may help to reduce seed numbers, but little research has been performed in that area. This herbicide is readily absorbed by the ryegrass leaves and roots and inhibits fatty acid synthesis. Hoelon can be used pre or postemergence. Unless the field has a history of heavy ryegrass infestation, an early postemergence application will be the most cost-effective treatment.
