AbstractSince 1970 the increasing level of Colorado potato beetle infestation in southwestern Ontario has necessitated foliage sprays or planting treatments with systemic insecticides. Spray tower tests of many insecticides against eggs, larvae, and adults indicated that the best overall materials would be carbofuran, azinphos-methyl, and chlorfenvinphos.At planting time furrow treatments with granular carbofuran, disulfoton, or phorate demonstrated good control of all potato pests until the end of June. After that time only the carbofuran and phorate treatments gave protection against a heavy second generation of potato beetles. Yields were related to the degree of pest control.
