摘  要:
田间试验结果表明,肟菌·戊唑醇在破口前5d喷施,能有效预防水稻穗颈瘟,其防效随着用药量的增加而显著提高,其中20g/667m2用药1次的防效为95.47%,显著优于肟菌·戊唑醇10g/667m2+三环唑40g/667m2破口前5d用药1次后齐穗期三环唑40g/667m2再用药1次的处理(高3.93个百分点),极显著优于肟菌·戊唑醇15g/667m2破口前5d用药1次的处理(高6.51个百分点),以及对照药剂三环唑40g/667m2破口前5d和齐穗期连续用药2次的处理(高16.38个百分点),持效期长、安全性好,而且田间综合表现为水稻青秆黄熟,因此在生产上具有良好的推广应用前景。

摘  要:
Field efficacy trials indicated that the single use of NATIVO( trifloxystrobin and tebuconazole 75% WG, 20g/ha.) had a good effect on preventing the rice neck blast. and disease controlling efficiency grew dramatically while dose was increasing with a maximum efficiency up to 95.47% when sprayed 5d once time before rupturing at the rate of 20g/ha. The performance was much superior to the treatment of spraying NATIVO(10g/ha.) and tricyclazole(40g/ha.) 5d once time before rupturing followed by spraying tricyclazole once time at heading stage, and the treatment of spraying NATIVO(15g/ha.) 5d once time before rupturing and the treatment of the control group. Therefore, NATIVO is long-lasting, safe and be beneficial to rice growth, and the product showed a good future of application and promulgation.
