Research on Resistance of Redroot Pigweed to Chlorimuron-ethyl in Several Areas of Liaoning

HUANG Yuan-yuan,JI Ming-shan*(College of Plant Protection,Shenyang Agricultural University,Shenyang 110161,China)  
Redroot pigweed seeds were collected from different soybean regions in Liaoning,through the agar and leaf treatment method,the research measured the resistance level of redroot pigweed in different regions to chlorimuron-ethyl,as well as the effects of chlorimuron-ethyl on the seedlings of redroot pigweed.The result showed the ratio of relative resistance of redroot pigweed in Tieling was 751,while that in Jinzhou and Dandong was 294.5,167 respectively.Multiples of relative virulence and resistance indexes for the seedling height,root length,plant fresh weight of sensitive population and resistant population of redroot pigweed in different regions were different to a certain extent.
