摘要
采用浸叶法测定了两种农药对黄野螟的增效作用及两种药剂复配的适宜配比。结果表明:阿维菌素与苏云金杆菌对黄野螟的制剂LC50值分别是0.0000001599mg/L和0.0006943385mg/L,前者毒力大于后者;两者以重量比为2∶8和1∶9混配时的增效作用最明显。
The synergistic effects of avermectin, Bacillus thuringiensis, and their mixtures on Heortia vitessoides were tested in the laboratory by the leaf-dipping method. The results showed that the LC50 of avermectin and Bacillus thuringiensis were 0. 0000001599mg/L and 0. 0006943385mg/L, respectively. The mixture of avermeetin and Bacillus thuringiensis with ratio of 2 ： 8 or 1 ： 9 had remarkable synergistic effects.
