The feasibility of soil spray treatment with butralin against weeds in pepper fields was studied.Indoor -pot and field -plot experiments were used to determine the weed efficacy,particularly against Amaranthus retroflexus,and selectiv-ity to pepper of butralin.When used to control weeds in pepper fields,butralin was selective to pepper with a safety coeffi-cient of 4.3.In the field plot experiment butralin provided adequate control of weeds such as Amaranthus retroflexus,with an overall control of 85% to 94%,and a fresh weight reduction of 89% to 96% at 40 days after application.Butralin not only controlled the weeds but also improved pepper yield.In conclusion,butralin can effectively and selectively control a wide spectrum of weeds in pepper fields.
