Abstract
Effective control was given by 5 weekly applications of dusts containing 1% rotenone, 3% DDT (setting point 103-5[degree] C), 5% chlordan, and 1% and 2% parathion. Dusts containing 10% sabadilla and 3% methoxychlor were less effective. Although 3% DDT (s. p. 90[degree]C), 1% gamma benzene hexachloride and 2% chlorinated camphene were effective, all were seriously phytotoxic. No phytotoxic symptoms occurred on any of 3 squash vars. dusted with 3% DDT (s. p. 103-5[degree] C) although the similar dust prepd. from technical grade DDT (s. p. 90[degree] C) caused serious injury to plants of the vars. Table Queen (Cucurbita pepo) and Butternut (C. moschata) although Blue Hubbard (C. maxima) was less affected. Chlordan and parathion dusts caused slight foliage injury which was outgrown after treatments ceased.This publication has 1 reference indexed in Scilit:
