CHEMICAL WEED CONTROL IN SPRING-SOWN BROAD BEANS

Summary. During the period 1956-61, twelve replicated field experiments were conducted to determine the response of spring-sown broad beans ( Vicia faba L.) and annual weeds to various pre- and post-emergence herbicides. On a sandy loam, the best results were given by pre-emergence applications of simazine 0.75 lb/ac, trietazine 1.5 lb/ac, chlorpropham 1 lb+diuron 0.2 lb/ac or dinoseb-amine 4 lb/ac. Amiben proved insufficiently selective, while chlorpropham+fenuron caused greater crop injury than the corresponding mixture with diuron. Post-emergence application of dinoseb-amine was less satisfactory than the best of the pre-emergence treatments.
