Abstract
The effect of 4 methods of application of chlordimeform and carbofuran on the uptake and persistence of their residues in rice plants was compared. The highest concentration of the residues of 2 insecticides in roots, stem, and leaf blade occurred when the insecticide, in gelatin capsules, was placed in the root zone of each hill of rice. The persistence of the insecticide residues in plant tissues was longer when the insecticide was incorporated into the top soil than when the compound was applied to the paddy water. Placement of the insecticide in the root zone in the center of 4 hills delayed absorption and translocation of the residues of chlordimeform and carbofuran.This publication has 1 reference indexed in Scilit:
