AgriPro® AP503 CL2 from Syngenta is a hard red winter wheat with two genes for tolerance to the Beyond family of herbicides. The use of methylated seed oil (MSO) with the herbicide can improve control of jointed goatgrass, feral rye, downy brome, and other problem grasses. AP503 CL2 has good test weight and straw strength, and is resistant to soil-borne mosaic. It has very good drought tolerance as well as excellent winterhardiness. It is slow to start in the spring after dormancy. AP503 CL2 is susceptible to leaf rust and stripe rust and would respond well to a fungicide application. Growers must sign a stewardship agreement stating that they cannot keep the grain produced for seed.
PVPA Status: Protected, must be sold only as a class of certified seed.
