PRN 2017-1, Guidance for Pesticide Registrants on Pesticide Resistance Management Labeling offers general guidance on resistance management labeling for all conventional agricultural insecticides, fungicides and herbicides. The primary component of IRM for Bt PIPs is the use of refuges to reduce selection pressure for resistance. Genetic engineering (GE) refers to techniques used to manipulate the genetic composition of an organism by adding specific genes. a)Natural enemies control, a gardener applied heavy dose if the same insecticide to her garden for two consecutive years killing squash bugs.
