Extract

In 1954 the authors reported studies involving the application of sodium 2,2–dichloropropionate (sodium salt of dalapon) to wild oats (Avena fatua) and concluded that treatment in the boot stage showed no promise in controlling viable seed production in wild oats. However, a lag in germination in seed from treated plants was noted in some instances (1). When seeds from these plants were planted in the greenhouse, many seedlings reached the coleoptile stage only, and failed to develop further (2).
