不同杀菌剂对马兰茎腐病的防治效果

Control Effects of Different Fungicides on Stalk Rot of Kalimeris indica

研究了70%甲基托布津可湿性粉剂(甲基硫菌灵)、40%施佳乐悬浮剂(嘧霉胺)、50%多菌灵可湿性粉剂、75%达科宁可湿性粉剂(百菌清)和40%福星乳油(氟硅唑)5种杀菌剂对马兰茎腐病的防治效果。结果表明:用40%福星乳油4 000倍液或40%施佳乐悬浮剂1 200倍液连续喷施3次,每次间隔7 d,防治马兰茎腐病效果最好,防治有效率均达到100.00%;70%甲基托布津可湿性粉剂800倍液和50%多菌灵可湿性粉剂800倍液防治效果次之,防治有效率分别为89.52%和81.26%。

The control effects of 70% thiophanate-methyl WP, 40% pyrimethanil SC, 50% carbendazim WP, 75% chlorothalonil WP and 40% flusilazole EC on stalk rot of Kalimeris indica were studied. The results showed that the control effects of spraying 4 000 times liquid of 40% flusilazole EC or 1 200 times liquid of 40% pyrimethanil SC three times were the best, and the control efficacy reached 100. 00%. The control effects of 800 times of 70% thiophanate-methyl WP and 50% carbendazim WP took second place, and the control efficacy reached 89. 52% and 81.26% , respectively.
