为防控南方水稻黑条矮缩病和水稻齿叶矮缩病,集成了拌种技术、送嫁药技术和关键时期关键药剂防治技术,筛选了不同含量噻虫嗪用药组合和配套技术。从种子、秧苗移栽到破口期全程预防,防控稻飞虱,阻断水稻病毒传播介体。试验结果表明,70%噻虫嗪ZF作拌种和送嫁药,25%噻虫嗪WG在分蘖盛期和破口期使用的配套技术,以及35%噻虫嗪ZX拌种,40%氯虫·噻虫嗪WG和5%氨基寡糖素AS作送嫁药及分蘖盛期使用,40%氯虫·噻虫嗪WG在破口期使用的配套技术,均能有效防控海南省水稻主要病毒病害。前者防效优于后者,分别为95.60%和60.92%。
In order to prevent and control southern rice black-streaked dwarf disease and rice leaf-dwarf disease, integrated seed dressing technology, delivery of drug-marrying technology and key agent control technology in key period were selected. Thiamethoxam combination and matching technologies were screened. From seeds, seedlings transplanted to break the full prevention, control planthoppers, blocking the transmission of rice virus mediators. The results showed that 70% thiamethoxam ZF was used as seed dressing and downdrow agent, 25% thiamethoxam WG was used at tillering stage and breaching stage, and 35% thiamethoxam ZX seed dressing and 40% chlorine Insect thiamethoxam WG WG and 5% amino oligosaccharides AS as send marrying and tillering peak use, 40% chlorantranilil thiamethoxam WG used in breaking the supporting technology can effectively prevent and control rice in Hainan Province The main virus disease. The former is better than the latter, with 95.60% and 60.92% respectively.
