东北永吉县稻田二氯喹啉酸类除草剂的连年使用,致使稗草对其产生了抗药性,本试验以理想的抗药性稗草和理想的敏感性稗草作为研究对象,研究其抗药性特征,并探求一些关于抗二氯喹磷酸类稗草的有效防除技术.1试验材料与方法1.1试验材料1.1.1供试植物采自多年连续使用二氯喹啉酸类除草剂的永吉县岔路河镇水稻田抗药性稻稗种子和口前镇水稻田敏感性稻稗种子。1.1.2供试药剂二氯喹啉酸(50%可湿性粉剂)、稻杰(2.5%油悬乳剂)、禾大
The continuous use of quinclorac-type herbicides in paddy fields in Yongji County of northeast China caused the resistance of barnyardgrass to it. In this study, the ideal resistant barnyardgrass and ideal sensitive barnyardgrass were studied to study its resistance characteristics , And to explore some effective anti-dichloroquine-resistant barnyard grass control technology.1 Test materials and methods 1.1 Test materials 1.1.1 The test plants were collected from years of continuous use of quinclorac herbicide Yongji County fork road town rice Field-resistant barnyard grass seeds, and paddy field-sensitive paddy barnyardgrass seeds in front of town. 1.1.2 Test agents Quinclorac (50% WP), rice Jie (2.5% oil emulsion), Wo large
