乙蒜.暗罗素是江苏丘陵地区镇江农业科学研究所开发的植物源类复配制剂,通过与几种植物源杀菌剂室内生测和田间防治试验表明,对草莓白粉病菌抑制作用从高到低为:乙蒜.暗罗素>暗罗素>蛇床子素>乙蒜素>细辛提取物,以乙蒜.暗罗素复配剂病情指数最低,防效最好。室内生物测定,乙蒜.暗罗素复配剂有效浓度2 000~4 000倍液,防效85.64%~88.72%,2 000倍高于4 000倍防效,但差异不显著。与其他几种植物源药剂防效差异均为极显著;田间防治草莓白粉病,25%乙蒜.暗罗素WP200倍和400倍浓度,7 d防效82.03%~83.43%,10 d防效72.69%~73.56%,两浓度间差异也不显著,而极显著于其他几种植物源农药单剂。
Garlic, garlic, dark garlic, garlic, dark garlic, garlic, garlic, garlic, garlic, garlic, garlic, garlic, garlic, etc. The Russell vegetarian is a botanical compound formulated by Zhenjiang Institute of Agricultural Sciences in hilly area of Jiangsu Province. Through experiments with several plant germicides indoor test and field control tests, As: B garlic. Dark Russell> Dark Russell> Osthol> Allicin> Asarum extract to ethyl garlic. Dark Russell compound with the lowest disease index, the best control. Indoor bioassay, ethyl garlic, dark Russell compound effective concentration 2000 ~ 4000 times, control effect 85.64% ~ 88.72%, 2000 times higher than 4000 times the control effect, but the difference was not significant. In the field, the powdery mildew of strawberry was treated with 25% ethyl garlic and the dark-Russell WP200 times and 400 times concentration, the control effect was 82.03% ~ 83.43% on the 7th day, and the control effect on the 10th d 72.69 % ~ 73.56%, the difference between the two concentrations is not significant, but very significant in several other plant-derived pesticides single agent.
