摘要
为有效防除油菜田小子虉草的危害,参照农药田间药效试验准则,在室内筛选的基础上开展了6种除草剂的田间药效试验和作物安全性评价,结果表明,5％唑啉草酯乳油、108 g/L高效氟吡甲禾灵乳油、12.5％烯禾啶乳油、10％精喹禾灵乳油、69 g/L精噁唑禾草灵水乳剂、150 g/L精吡氟禾草灵乳油等6种药剂对油菜田小子虉草表现出较好的防效,且对油菜非常安全,其中优先选5％唑啉草酯乳油于小子虉草6叶期前进行喷雾施用,施药30 d后,对小子虉草的鲜重防效可达98.61％,防治效果最好.
Abstract
In order to effectively control the weeds Phalaris minor Retz.in rapeseed fields,the field efficacy trials and crop safety evaluation of six herbicides were carried out on the basis of indoor screening according to the field efficacy test criteria of pesticides.The results showed that pinoxaden 5％EC,haloxyfop-P-methyl 108 g/L EC,sethoxydim 12.5％EC,quizalofop-P 10％EC,fenoxaprop-P-ethyl 69 g/L EW and floazifop-p-butyl 150 g/L EC had good control effects on Phalaris minor Retz.in rapeseed fields and were very safe to rape.Among them,pinoxaden 5％EC was preferentially selected for control the weeds using spraying method before the 6-leaf stage of Phalaris minor Retz.,and showed the excellent control efficacy based on the weed fresh weight(98.61％)against Phalaris minor Retz after 30 days of spraying.
