5%唑啉·炔草酯EC与3种阔叶杂草除草剂混配对返青期小麦的药害程度分析
摘要
Abstract
In order to find out the herbicide mixed use combinations and their dosage that causes damage to the wheat field,the experiment selects four kinds of herbicides,i.e.Pinoxaden 50 g/L EC,Florasulam+Flumetsulam 58 g/L SC,MCPA-Na 560 g/L SP,and Fluroxypyr 200 g/L EC to carry out the experiment of multiple mixed use spray application.Through multiple drug injury inves-tigation,it is concluded that 4 times the amount of Pinoxaden 50 g/L EC as well as Pinoxaden 50 g/L EC mixed with MCPA-Na 560 g/L SP with the 2-fold and 3-fold amounts of drug cause more serious drug injury,which is not easy to recover,and causes some yield loss;A 3-fold dose of Pinoxaden 50 g/L EC,a 1-fold dose of Pinoxaden 50 g/L EC mixed with MCPA-Na 560 g/L SP,and a 2-fold dose of Pinoxaden 50 g/L EC mixed with Fluroxypyr 200 g/L EC produces mild drug damage,which recovers later.The admixture of Pinoxaden 50 g/L EC with Florasulam+Flumetsulam 58 g/L SC is not prone to be harmful to the wheat field and makes the herbicidal profiles very complementary,with one application effectively removing major weeds in the wheat field.关键词
