The combination of a reduced rate (from 1 lb to 0.5 lb) and fewer applications (5) of insecticide, for control ofHeliothis zea(Boddie) to a resistant sweet corn hybrid, (471–U6X81–1) resulted in significantly fewer damaged ears than with 7 applications of insecticide to a susceptible hybrid. Also, one application of insecticide at the reduced rate to the resistant hybrid gave control equal to that achieved with 7 applications to the susceptible hybrid. Thus, a program of insect control involving this resistant variety plus less insecticide would be more economical and would reduce pollution of the environment.
