  • BLENDED REFUGE DEPLOYMENT VIA MANIPULATION DURING HYBRID SEED PRODUCTION
    Publication number: 20100210460
    Abstract: Insect refuge strategies are described for the management of insect resistance development. The present invention relates generally to the control of pests that cause damage to crop plants, and in particular to corn plants, by their feeding activities directed to root damage, and more particularly to the control of such plant pests by ensuring, through the seed production process, that sufficient refuge seeds are present in a given set of seeds to reduce the rate of development of resistant pests, thereby eliminating the problems that may arise with regard to refuge compliance. In addition, the treatment of such seed with a chemical or peptide-associated pesticide prior to planting the seed is also disclosed.
