苯磺隆等麦田除草剂对部分经济林木的安全性测定

苯磺隆、甲磺隆、绿磺隆是麦田高效除草剂。在小麦与枣树、核桃树、梨树、苹果树、花椒树等间作的农田里，小麦返青后，各种树未展叶时使用上述除草剂，不会对上述树种产生任何影响，但在小麦拔节以后，各种树木完全展开叶再施药，则易对枣树和梨树产生药害，应慎用

SAFETY EVALUATION OF SULFONYLUREA HERBICIDES ON SOME TREES OF ECNOMIC VALUE

ibenuron-methyl,methsulfuron-methyl and chlorsulfuron are efficient herbicides on wheat field.During winter wheat return green to jointing,trees of ecnomic value having no any new leaves,using these herbicides on the land planted apple,pear,jujube or walnut mixed with winter wheat is very safe.But fater winter wheat jointing,these trees appearing new leaves,these herbicides can cause phytotoxicity on pear and jujube.
