通过2010、2011年试验评价氟硅唑和春雷霉素对番茄叶霉病的田间应用效果,10%氟硅唑EW低剂量处理防效均在65%以上,中剂量处理防效均为74%以上,而高剂量处理防效均在82%以上,且对番茄植株生长无不良影响,推荐有效成分用量为67.5~75 g/hm2。2%春雷霉素AS的平均防效为60.28%~76.61%,其高剂量处理与氟硅唑中剂量处理的防效差异不显著,因此将其高剂量(52.5 g/hm2)作为防治适宜用量。
The field application effects of fluaziridis and kasugamycin against tomato leaf mold were evaluated through 2010 and 2011 tests. The control efficacy of low dose of 10% flusilazole EW was above 65% and that of middle dose was 74% , While the control effect of high-dose treatment was above 82%, and had no adverse effect on the growth of tomato plants. The recommended effective ingredient dosage was 67.5-75 g / hm2.2% The average control effect of kasugamycin AS was 60.28% -76.61 %, The control effect of high-dose treatment and flusilazole medium dose was not significant, so its high dose (52.5 g / hm2) as the appropriate amount of prevention and treatment.
