Abstract
This experiment was conducted to evaluate the effect of polyethylene film(P.E.) mulching on degradation of the soil insecticides, endosulfan(6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9-methano-2,4,3-benzodioxathiepin-3-oxide), fonofos(O-ethyl S-phenyl ethylphosphonodithioate), and ethorprophos(O-ethyl S, S-dipropyl phosphorodithioate) in red pepper, peanut, and sesame fields. Degradation of endosulfan, fonofos and ethoprophos in the soils under P.E. mulching and non-mulching followed first-order kinetics. The half-lives of fonofos, ethoprophos,
폴리에틸렌(P.E.)필름 피복재배조건하(被覆栽培條件下)의 고추, 땅콩, 참깨포장(圃場)에 있어서 endosulfan, fonofos, ethoprophos의 잔류성(殘留性)을 로지조건(露地條件)과 비교조사(比較調査)한 결과(結果)는 다음과 같다. 토양중(土壤中)에서 endosulfan, fonofos, ethoprophos의 분해(分解)는 양조건하(兩條件下)에서 1차반응식(次反應式)에 따랐다. 토양중(土壤中) 잔류기간(殘留期間)은 유기인계(有機燐系)인 fonofos(반감기(半減期) :
