一种菜青虫杀虫剂的制备方法及防治效果
|
摘要
以虎掌草、青蒿、黄花烟的浸提液和石灰水、食盐水为材料,按照适宜的质量配比,连续2年对菜青虫进行田间药效试验。结果表明,虎掌草母液、青蒿母液、黄花烟叶母液、石灰水、食盐水、清水按质量比4:2:2:1:1:6、4:2:0:1:1:8、4:0:2:1:1:8、0:4:2:1:1:8的比例配合,防效分别为82.7%～89.8%、38.3%～42.0%、41.0%～45.4%、52.9%～56.4%。综合2年田间平均防治效果,虎掌草母液、青蒿母液、黄花烟叶母液、石灰水、食盐水、清水按质量比4:2:2:1:1:6的比例配合,防效显著,防治效果最好,已获国家发明专利。
The leaching solution of Anemone rivularis Buch.-Ham., Artemisia carvifolia and Nicotianal rustica L., whitewash and salt water were used as materials. According to the appropriate quality ratio of materials, field control effectiveness test to cabbage worm were conducted for two consecutive years. The results showed that when the quality ratio of leaching solution of Anemone rivularis Buch.-Ham., Artemisia carvifolia, Nicotianal rustica L. whitewash, salt water, clear water was 4:2:2:1:1:6, 4:2:0:1:1:8, 4:0:2:1:1:8 and 0:4:2:1:1:8, the control efficiency of insecticide were 82.7%～89.8%,38.3%～42.0%,41.0%～45.4% and 52.9%～56.4%, respectively. Combine the two years experiment results, the insecticide had the best controlling effect when the quality ratio of leaching solution of Anemone rivularis Buch.-Ham., Artemisia carvifolia, Nicotianal rustica L.,whitewash, salt water, clear water was 4:2:2:1:1:6. The technology had obtained national invention paten.
