为了测定醚菌酯可湿性粉剂对黄瓜白粉病的防治效果及最佳使用剂量,为大面积推广提供科学依据,黑龙江省农业科学院植物保护研究所研究人员在省农科院园艺分院黄瓜大棚用30%醚菌酯可湿性粉剂247克/公顷,50%醚菌酯可湿性粉剂150克、247克、315克/公顷,以及空白等5个处理进行了田间药效试验。试验防治黄瓜白粉病药效结果表明,在空白对照的黄瓜白粉病平均病指达45.39情况下,50%醚菌酯可
In order to determine the effect of the kresoxim-methyl WP on cucumber powdery mildew and the best dose, to provide scientific basis for large-scale popularization, researchers at Institute of Plant Protection of Heilongjiang Academy of Agricultural Sciences in the horticultural branch of the Provincial Academy of Agricultural Sciences cucumber greenhouse with 30 Field experiments were conducted on 5 treatments including 247 g / ha of kresoxim-methyl wettable powder, 150 g of 50% kresoxim-methyl WP, 247 g, 315 g / ha and blank treatment. Test cucumber powdery mildew efficacy test results showed that in the blank control cucumber powdery mildew mean index of 45.39 cases, 50%
