摘要
为找出对麦田产生药害的除草剂混用组合及用量,试验选用5%唑啉·炔草酯EC、5.8%双氟·唑嘧胺SC、56%二甲四氯钠SP、20%氯氟吡氧乙酸EC四种麦田除草剂进行多倍混用喷施试验。通过多次药害调查,得出4倍药量的5%唑啉·炔草酯EC以及5%唑啉·炔草酯EC与56%二甲四氯钠SP混配2倍、3倍药量均会产生较重药害,且不易恢复,并造成一定的产量损失;3倍药量的5%唑啉·炔草酯EC、1倍药量的5%唑啉·炔草酯EC与56%二甲四氯钠SP混配、2倍药量的5%唑啉·炔草酯EC与20%氯氟吡氧乙酸EC混配会产生轻度药害,后期可恢复。5%唑啉·炔草酯EC与5.8%双氟·唑嘧胺SC混配不易产生麦田药害,并且使杀草谱具有很好的互补性,一次施药能有效防除麦田主要杂草。
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 investigation,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.
