1989年起我们浙江省金华市水稻细菌性条斑病研究协作组对水稻细条病从种子处理、秧板消毒、秧苗防治、本田期防治的药剂筛选及防治方法作了试验研究,结果如下:稻种药剂处理,病稻种用强氯精300倍液浸种,盆栽试验结果,细条病的初见期推迟14天,防治效果达73.82%;田间试验结果,移栽后23天时防治效果为63.4%,移栽后55天时防治效果下降到16.32%。秧板消毒效果,每亩用500g 强氯精和双效灵作秧板消毒,移栽后56天的防治效果分别为34.67%和46.11%。秧苗喷雾防治效果,每亩150g
Since 1989, we collaborate in researching rice bacterial leaf streak disease in Jinhua City, Zhejiang Province on the screening and control methods of rice sliver disease from seed treatment, seedling disinfection, seedling control, Honda period prevention and control. The results are as follows: Rice Seed treatment, rice seed soaking with strong chlorine 300 times, the pot test results, thinning disease delayed the initial period of 14 days, the control effect of 73.82%; field test results, 23 days after transplanting control effect was 63.4% At 55 days after transplanting, the control effect dropped to 16.32%. Seedling disinfection effect, with 500g of strong chlorine per acre and double-effect seedlings for disinfection, prevention and control of 56 days after transplanting were 34.67% and 46.11%. Seedling spray control effect, 150g per acre
