Abstract
Cypermethrin and carbaryl, as both aqueous sprays and bran baits, were tested in the field as crop protection measures against third-instar grasshopper populations infesting bromegrass and alfalfa–bromegrass pastures. Application of 15 g cypermethrin/ha as a spray reduced the grasshopper populations by 97% within 120 h; 700 g carbaryl/ha as spray reduced the populations by 90% during the same period of time after application. Neither insecticide applied on bran bait sufficiently reduced populations to be useful as crop protection measures against grasshoppers.This publication has 5 references indexed in Scilit:
