32%滴酸·草甘膦对非耕地杂草防除药效研究

Preliminary Study on the Control Effect of 32%Acid Glyphosate on Non-arable Weeds

为明确32%滴酸·草甘膦可溶液剂对防除非耕地杂草的用药量、防除对象、防除效果、使用适期和周围环境安全性的影响,按昭《农药田间药效试验准则(一)》和广西壮族自治区农业科学院植物保护研究所农药田间药效试验标准操作规程进行了除草剂防非耕地杂草田间药效试验。试验结果表明,32%滴酸·草甘膦在1215~2430 g/hm^(2)的剂量下,兑水675 L/hm^(2),在杂草旺盛生长期进行茎叶喷雾处理,能够有效防除非耕地大部分杂草,对非耕地杂草防除效果良好。

In order to determine the effects of 32%acid and glyphosate solution on the quantity,target,effect,suitable period of application and surrounding environmental safety of weed control in non-cultivated land,field efficacy trials of herbicide against weeds in non-cultivated land were conducted according to the Guidelines for Field Efficacy Trials of Pesticides(I)and the standard operating procedures for field efficacy trials of pesticides of Plant Protection Institute of Guangxi Academy of Agricultural Sciences.The results showed that 32%acid and glyphosate at the dosage of 1215-2430 g/hm^(2),mixed with water 675 L/hm^(2),can effectively control most weeds in non-cultivated land,and has a good effect on weed control in non-cultivated land.
