摘要
研究了吡蚜酮浸种和拌种处理对灰飞虱的防治效果和水稻条纹叶枯病的控制效果。结果表明,秧田揭膜后5~11 d,25%吡蚜酮WP 200~400倍液浸种处理对灰飞虱成虫的防效在55.70%~74.88%之间;移栽后40 d,对水稻条纹叶枯病株防效在70.50%~72.34%。25%吡蚜酮WP 2~8 g/kg拌种对灰飞虱成虫防效在57.84%~86.30%,对水稻条纹叶枯病株防效在64.51%~75.51%。
The control effects of treating rice seeds with Pymetrozine(seed-soaking or seed-dressing) on Laodelphax striatellus and rice stripe virus were studied.The results showed that the control effect of soaking seeds with 200~400 times dilution of 25% Pymetrozine WP against the adults of L.striatellus was 55.70%~74.88% on the 5th^11st day after removing the film of seedling field,and that against rice stripe virus was 70.50%~72.34% on the 40th day after transplanting rice.The control effect of dressing seeds wit...
