为筛选能有效防除抗精噁唑禾草灵杂草的除草剂,山东农业大学植物保护学院和安徽科技学院农学院研究人员合作,采用温室盆栽法测定菵草(敏感Sw、抗性Rw)、日本看麦娘(敏感Sr、抗性Rr)、耿氏硬草(敏感Sy、抗性R)对精噁唑禾草灵的抗性水平,并研究了8种除草剂对这3种抗性杂草的生物活性。结果显示,3种杂草抗性种群对精噁唑禾草灵的抗性指数均大于33.7,
In order to screen the herbicides that can effectively control the anti-oxazofen weeds, the cooperation of Shandong Agricultural University Plant Protection College and Anhui Institute of Science and Technology Agricultural Science and Technology College researchers was carried out. Potted grass (sensitive Sw, resistant Rw) In Japan, the resistance of Ophiopogon japonicus (sensitive Sr, resistant Rr), hardy Güntin (sensitive Sy, resistant R) to fenoxaprop-citrate was studied, and the effects of eight herbicides on these three resistances Biological activity of weeds. The results showed that the resistance index of the three weed-resistant populations to fenoxaprop was greater than 33.7,
