21种茎叶处理除草剂对刺萼龙葵的生物活性研究
A Study on the Biological Activity of 21 Foliar-applied Herbicides against Solanum rostratum
摘要
Abstract
To screen safe and effective herbicides to prevent and control buffalobur, pot experiments were conducted to evaluate the control effect of 21 postemergent broadleaf herbicides against buffalobur and greenhouse bioassay was further conducted for herbicides with better control effects. The results showed that fresh weight inhibition of 7 herbicides was more than 90. 0% at the recommended dose. The toxicity of bromoxynil octanoate was the highest with ED90 of 67.31, while that of fomesafen was the lowest, with ED90 of 795.47 g/hm2. The order of toxicity was bromoxynil > fluroxypyr > paraquat > triclopyr > picloram > glyphosate > fomesafen. Based on consideration of herbicidal activity and recommended dose of the 7 herbicides, bromoxynil, fluroxypyr, paraquat, triclopyr, picloram and glyphosate could be used to control buffalobur at lower dose than recommended , but fomesafen should be used at a higher dose.关键词
