- 摘要:
- 采用800、1 000、1 200、1 500倍4种浓度的5%除虫菊素乳油对孔雀竹芋红蜘蛛进行防效试验。结果表明：800、1 000倍液5%除虫菊素乳油对孔雀竹芋红蜘蛛的防效浓度效果最好，防效可达90%以上，能有效防治孔雀竹芋红蜘蛛；且5%除虫菊素乳油药后3 d和药后5 d对孔雀竹芋红蜘蛛的防治效果比药后1 d略有下降，药后7 d其防效大幅下降，降到80%以下，因此，建议生产中施药间隔时间以7 d为宜。
- Abstract:
- Efficacy tests on Tetranychus cinnbarinus of Calathea makoyana for 5% pyrethrin in concentrations of 800 folds，1 000 folds，1 200 folds and 1 500 folds were studied.The results showed that best effect，which was over 90%，appeared with concentrations of 800 folds to 1 000 folds，however the results on 3 d and 5 d were declined comparing with 1 d after application，and the effect dropped drastically，which was not up to 80% on 7 d.Therefore，an interval of 7 d was suggested in practice.
