笔者于1992年在咸宁马桥、杨下进行了克芜踪防除茶园杂草的试验,效果十分理想。试验设置了清水对照、100ml/666.7m~2、150ml/666.7m~2三个处理,每处理三个重复,在施药当天、15天、30天各进行了杂草情况调查。施药15天后,666.7m~2用100ml克芜踪对马唐、狗芽根、小藜、一年蓬、辣蓼、白茅的防效分别为97.4％、98.3％、96.9％、94.6％、95.5％、87.4％;666.7m~2用150ml,其防效分别为100％、 The author in 1992 in Xianning Maqiao, Yang under the Wuhu trace control of weeds in the tea plant test, the effect is very satisfactory. The experiment set up a clear water control, 100ml / 666.7m ~ 2,150ml / 666.7m ~ 2 three treatments, each treatment of three replicates, in the application of the day, 15 days, 30 days weeds were investigated. After 15 days of application, the control efficacy of 666.7m ~ 2 with 97%, 98.3%, 96.9% and 96.6% respectively on Crabgrass, Dogradish Stem, Chenopodiaceae, 95.5%, 87.4%; 666.7m ~ 2 with 150ml, the control effect was 100%, respectively,
