| 中文摘要: |
| 为减少化学农药在稻田的使用，在四川新都进行了2种生物农药混配制剂甜核·苏云菌防治水稻二化螟试验和示范。结果表明：采用PB 16手动喷雾器防治试验，甜核·苏云菌对水稻二化螟的枯心、白穗和虫伤株的防治效果分别为98.0%、99.56%和99.29%，采用东〖CD*2〗18机动喷雾器喷雾示范，甜核·苏云菌对二化螟的枯心、白穗和虫伤株的防治效果分别为96.44%、97.83%和96.69%，效果良好，可以在大面积生产中推广应用。 |
| 英文摘要: |
| To reduce chemical pesticide use in paddy fields, we tested the Beet armyworm nuclear polyhedrosis virus·Bacillus thuringiensis, a mixture of 2 bio pesticides, for its effects on the rice stem borer in Xindu county. The results of field trials showed that, by using the PB 16 manual sprayer, its control efficacies to dead heart, dead head and infested plants were 98.0%, 99.56% and 99.29%, respectively; by using the Dong 18 machine sprayer, its control efficacies were 96.44%, 97.83% and 96.69%, respectively. The mixture can be extended for large scale use in agricultural production. |
