几种农药颗粒剂对月季蚜虫防治效果研究

研究了6种颗粒剂对月季蚜虫防治效果及持效期,以期筛选出对蚜虫防治速效性及持效期优良的新型颗粒剂,替代高毒农药颗粒剂。调查根埋施药后7 d、16 d、24 d、44 d对月季蚜虫的防治效果;并进行数据处理分析。研究结果表明:2%吡虫啉颗粒剂1.5 g、4.5 g处理和0.5%阿维菌素颗粒剂9 g处理,在防治月季蚜虫的速效性和持效期方面,显著高于其他药剂处理,可以作为高毒药剂3%呋喃丹颗粒剂的替代品。综合防治的速效性、持效期、经济性和药剂安全性方面,2%吡虫啉颗粒剂每株施药1.5 g最优,具有较大的应用价值。

Study on control effect of several pesticide granules rose aphid

This paper studies 6 kinds of granule in treating effect on aphid rose and persistence, In order to select the rapid available for control of aphids and hold new granules excellent effect , instead of high toxic pesticide granules. Control effect of 7D, 16d, 24D, 44d on rose aphid investigation roots after application, And the data processing and analysis. The results show that: 2% imidacloprid granules per plant pesticide 1.5g ~ 4.5g and 0.5% abamectin GR 9g available on rose aphid control and effective duration, significantly higher than other treatments, can be used as high toxic chemicals control 3% carbofuran granules alternatives, Integrated control of rapid available, effective duration, economy and safety, 2% imidacloprid granules per plant pesticide 1.5g as the optimal treatment.
