60%吡虫啉悬浮拌种剂(高巧)对防治水稻飞虱和预防病毒病的效果评价

60% Imidacloprid Suspension Seed Dressing Agent(Gaoqiao) against Rice Plant-hopper and Virus Disease

试验通过用60%吡虫啉悬浮拌种剂(高巧)等药剂进行拌种,考究其对水稻飞虱、稻蓟马、恶苗病的防治以及南方水稻黑条矮缩病、锯齿叶矮缩病等病毒病的预防效果。试验结果表明:高巧种子处理剂对防治水稻秧苗期稻飞虱和预防"南矮"的发生有较好的作用,且对水稻体质有一定的促进作用,主要体现在可促进叶片和根系的生长,进而促进植株分蘖数、株高、地上和地下部分鲜重、茎基宽和产量结构的提高,最终提高水稻产量。

60% imidacloprid suspension seed dressing agent （Gaoqiao） was used to dress the seed in the experiment to test the control and prevention effects on rice plant-hopper, rice thrips, bakanae disease, southern rice black streaked dwarf disease and the ragged stunt disease virus disease. The test results showed that： Seed treatments with Gaoqiao had better control and prevention effects on Rice Plant-hopper in seedling stage and southern dwarf, and had positive promotion effects on rice growth, mainly in promoting its leaf and root growth, and thus promoting the tiller number, plant height, aboveground and underground parts of fresh weight, width of stem and yield structure. And so the dressing treatment ultimately could raise the yield of rice.
