该研究开展了15%丙唑·戊唑醇SC对小麦赤霉病的防治效果试验。结果表明,在小麦齐穗初花期(扬花5%~10%)用第一遍药,隔5~7d用第二遍药,15%丙唑·戊唑醇SC 1 050g/hm2的病穗防效、病指防效分别为56.08%、58.05%,与40%多·酮WP 2 250g/hm2的防治效果相当;15%丙唑·戊唑醇1 500g/hm2的病穗防效、病指防效分别为68.61%、72.15%,优于40%多·酮WP 2 250g/hm2的防治效果。
The study carried out a 15% propiconazole tebuconazole SC control test of wheat scab. The results showed that in the first flowering stage (5% ~ 10% of flowering) of wheat, the first pass was used, the second pass was applied every 5 ~ 7 days, the panicle spike of 15% propiconazole tebuconazole SC 1 050g / hm2 The control efficacy of disease index was 56.08% and 58.05%, respectively, which was equivalent to that of 40% WP and 250 g / hm2 WP. The control effect of 15% propiconazole and tebuconazole 1 500 g / The control effects were 68.61% and 72.15%, respectively, which were better than those of 40% WP 2 250g / hm 2.
