Abstract
Cotton plants grown in sand culture treated with P32-labeled dimethoate accumulated more insecticide in the leaves under environmental conditions which favored transpiration. Fruiting cotton plants treated with dimethoate as a soil drench accumulated relatively small amounts of the toxicant in the squares and bolls. Less than 1 microgram of dimethoate-equivalents was found in the stamens plus pistil of squares upon which the developing boll weevil (Anthonomus grandis Boheman) larvae feed. Young cotton plants grown in dimethoate-treated nutrient solutions did not absorb the insecticide at the same rate they absorbed water. Also, plants grown in nutrient solutions deficient in phosphorus absorbed less insecticide than plants grown in a complete nutrient solution.This publication has 1 reference indexed in Scilit:
