CR seed is recommended. So the real decision is whether to use CR varieties with the base (Mendel or first generation) resistance trait or use CR varieties with second generation traits… -
Fall is a good time to collect soil for a clubroot DNA test. Information can be used to help with seed and disease management decisions…
