三种无公害农药对杏坚球蚧的防治试验

摘要

应用石硫合水剂、阿维高氯、腊蚧灵三种农药对杏坚球蚧进行防治试验。结果表明：阿维高氯、石硫合水剂、腊蚧灵和对照四种处理的种群趋势指数分别为0.4148、0.8328、4.9908、6.3925,这说明阿维高氯和石硫合水剂处理区的杏坚球蚧种群数量呈显著下降趋势,而腊蚧灵和对照区的仁用杏球坚蚧种群数量呈明显增长趋势;应用阿维高氯和石硫合水剂防治杏球坚蚧效果良好。%Lime sulphur,abamectin betacypermethrin,scale insect kills as well as CK were applied to control the apricot stone shells.The results showed that the index of population trends of the four treatments were 0.4148、0.8328、4.9908、6.3925,respectively.Quantity of the insects was obviously decreased with the treatments of lime sulphur and abamectin betacypermethrin while the quantity of insects with other two treatments was significantly increased.
