不同农药联用对松材线虫的作用研究
|
摘要
以阿维菌素和甲维盐为主药,选用市场上常用农药,开展农药联用室内毒力测定和林间药效试验。结果表明,从各单剂农药有效成分LC50可以看出,甲维盐的有效成分LC50最小,阿维菌素和噻唑磷次之,吡虫啉相对较大,毒死蜱最大,其有效成分LC50分别为0.60、3.20、3.69、19.62和32.41 mg/L。供试的所有联用农药CTC均大于120,表现为增效作用。其中以阿维菌素+毒死蜱、甲维盐+毒死蜱增效最明显,CTC值分别为440.99和451.48。甲维盐+噻唑磷、甲维盐+吡虫啉、阿维菌素+吡虫啉、阿维菌素+噻唑磷的增效作用次之,CTC值分别为248.81、208.10、194.33和174.17。甲维盐+阿维菌素增效作用最小,CTC值为120.37。选用阿维菌素+毒死蜱、甲维盐+毒死蜱做林间药效试验,结果表明2种配方防治效果分别为78.7%、89.4%。
Abamectin and emamectinbenzoate were used as the main drugs,and the commonly used pesticides in the market were selected to carry out laboratory toxicity test and forest efficacy test for pesticide combinations. The results showed that the effective component LC50 of emamectin-benzoate was the smallest(0.60 mg/L), followed by abamectin and fosthiazate, the effective component LC50 of chlorpyrifos was the largest(32.41mg/L). CTC of all the tested pesticides was greater than 120, showing synergistic effect. The synergistic effects of abamectin +chlorpyrifos and emamectinbenzoate+chlorpyrifos were the most obvious, and the CTC values were 440.99 and 451.48, respectively.The CTC values of emamectin-benzoate +fosthiazate,emamectin-benzoate +imidacloprid, abamectin +imidacloprid, and abamectin +fosthiazate were 248.81, 208.10, 194.33 and 174.17, respectively. The synergistic effect of emamectin-benzoate +abamectin was the least, and the CTC value was 120.37. The abamectin +chlorpyrifos, emamectin-benzoate +chlorpyrifos were selected to carry out forest efficacy test. The results showed that the control effects of the two pesticide combinations were 78.7% and 89.4%, respectively.
