摘要
研究结果表明,综合防治与当地习惯防治相比,有翅蚜减少72.0%,地老虎断苗株率减少80.1%,烟青虫为害株率减少86.3%,上等烟比例提高近一倍,每亩增加收入80~110元。通过对害虫的测报,指导烟农合理施药,不仅防治效果好,而且减少用药2~3次。
Results showed that the ncember of winged aphides was decreased by 72. 0% with integrated control as compared with local conventional control significant difference in the aphid number in the fields was α=0. 001. The rates of broken seedlings by cutworms and injured plants by tobacco worms were decreased by 80. 1% and 86. 3%,respectively. The proportion of high quality tobacco nearly doubled and the income per mu was increased by 80-110 yuan.Prediction of pests and proper application of pesticides not only can get good control results, but also can reduce 2-3 times of applying pesticides.
