Applications of insecticide-fertilizer mixtures were made in the sugar beet seed-furrow. Evaluated materials exerted separate and independent influences on germination and subsequent development of beets with deleterious effects confined to beet seeds and seedlings. While beets did not respond significantly to applications of up to 1 pound per acre of actual aldrin or heptachlor, phytotoxicity from similar treatments with phorate or Di-Syston® (O,O-diethyl S-2-(ethylthio)ethyl phosphorodithioate) was expressed by reduction in germination, retarded seedling growth, and inadequate final stands. Granulated formulations appeared to be slightly less phytotoxic than emulsifiable concentrate formulations of aldrin, heptachlor, and phorate.
