在甘蔗二点螟第一代蛾高峰期和30天后各喷一次药,稻腾10%悬浮剂标签推荐剂量1000倍在第一次施药后15、30天和60天对枯心苗防治效果分别为52.1%、68.5%和77.3%,从统计学上极显著地高于氯虫苯甲酰胺20%悬浮剂标签推荐剂量3000倍的31.9%、54.6%和62.4%的同期防治效果,且用药成本相当。和清水对照处理相比,稻腾对甘蔗的茎长、茎径都有明显增加,特别是增产作用尤为明显,增产幅度达15%以上。
The first generation of sugarcane Polar second instar moth peak and 30 days after spraying a drug, rice straw 10% Suspension labeling recommended dose 1000 times the first application 15,30 days and 60 days on the seedling control effect Respectively, 52.1%, 68.5% and 77.3% respectively, statistically significantly higher than the recommended control efficacy of 31.9%, 54.6% and 62.4% of the recommended dose of chloramphenicol 20% suspension label, The cost is quite Compared with the control water treatment, the rice stem had a significant increase in stem length and stem diameter of sugarcane, especially the yield increase effect was more obvious, the yield increase of more than 15%.
