Study on Control Effect of Different Fungicides Coating on Fusarium Wilt of Castor Bean

不同杀菌剂种子包衣对蓖麻枯萎病的防效研究结果表明:苗期以50%速克灵可湿性粉剂和43%好力克乳油对蓖麻枯萎病的防效较好,其次为70%甲基托布津可湿性粉剂、20%三唑酮可湿性粉剂和75%百菌清可湿性粉剂;成株期以20%三唑酮可湿性粉剂和43%好力克乳油对蓖麻枯萎病的防效较好;生产上建议使用20%三唑酮可湿性粉剂、43%好力克乳油作为防治蓖麻枯萎病的药剂。

Study on control effect of different fungicides coating on fusarium wilt of castor bean results showed that the 50% procymidone WP and 43%horizon SC had betteer control effect than other fungicides,70% thiophanate-methyl WP,20% triadimefon WP and 75% chlorothalonil WP on fusarium wilt of castor bean were secondly better than others fungicides in seedling stage.The 20% triadimefon WP and 43%horizon SC had better control effect than others fungicides in adult stage. The 20% triadimefon WP and 43% horizon SC were suggested as the control fungicides of fusarium wilt of castor bean.
