【摘要】 在室内对25种杀菌剂抑治小麦赤霉病菌菌丝生长效果进行了测定。结果表明,25种杀菌剂中高效的药剂有6种(EC50值<0.5ppm),分别为40%灭病威胶悬剂、40%多菌灵胶悬剂、30%纹霉净可湿粉剂、80%多菌灵超微粉剂、20%多菌灵可温粉剂、50%多菌灵可湿粉剂。中效的药剂有7种(EC50值在0.5-20ppm之间),其中有70%甲基托布津可湿粉剂、20%粉锈宁乳油等。低效的药剂有12种(EC50值>20ppm)。更多还原

【Abstract】 Inhibitory actions of 25 kinds of fungicides to Wheat Head Scab hypha growth were measured in Laboratory. The results showed that there were 6 kinds of highly effect fungicides(EC50 value < 0.5 ppm)among 25 kinds of fungicides, which they are 40% Miebingwei SC ,and 40% Carbendazim SC, and 30% Wenmeijing WP, and 80% Carbendazim GP, and 20% or 50% of Carbendazim WP. There were 7 kinds of Medium effect fungicides (EC50value was at 0.5-20 ppm) , such as 70% thiophanate-methyl WP and 20% triadimefon EC etc. There were 12 kinds of low effect fungicides (EC50 value > 20 ppm).更多还原
