Johnsongrass is one of the most persistent and aggressive weeds faced by pasture and hay producers in North Georgia. Its rapid growth and rhizome-based spread can quickly crowd out desirable forages like fescue, reducing forage quality and yields. Fortunately, CryderTM herbicide offers an effective solution for managing this troublesome weed in perennial grass systems.
Cryder (active ingredient: nicosulfuron) is labeled for use in established perennial pastures and hayfields. When applied at the recommended rate of .75 oz per acre, Cryder provides selective post-emergent control of Johnsongrass without injuring fescue. For best results, treat when Johnsongrass is 18 to 24 inches tall and actively growing. Applications made too early or too late in the growth stage may reduce effectiveness.
Application Tips: Always add a non-ionic surfactant (NIS) at a concentration of 0.25% v/v to enhance herbicide uptake. Avoid mowing or grazing for 7 days before and after application. Follow all label restrictions for grazing and haying intervals, especially if applying to mixed grass/legume stands . Cryder works systemically, translocating to the root system to suppress regrowth. While one application often provides season-long control, heavy infestations or regrowth may require a follow-up treatment. By incorporating Cryder into your pasture management plan, you can suppress Johnsongrass while preserving your valuable fescue stands, promoting better forage production and pasture longevity.
