Two years of field experiments have shown that 3,4-dichloro propionanilide (DPA) can selectively control watergrass, Echinochloa crusgalli (L.) Beauv. in rice when used as a foliage spray. In 1960 yields of rice were increased by as much as 4,700 pounds per acre as a result of weed control from DPA applied at rates of 2, 4, and 8 pounds per acre. The only injuries observed were necrotic areas at the tips of rice leaves. In no case was subsequent growth of rice adversely affected by treatments.
