5种杀菌剂防治水稻稻曲病的效果比较

Comparative test on drug efficacy of five fungicides on controlling rice false smut

摘要: 进行30%戊唑·多菌灵SC、43%戊唑醇SC、30%苯甲·丙环唑EC、12.5%氟环唑SC、3%井冈霉素AS等5种杀菌剂防治水稻稻曲病的田间药效试验,结果表明:每667 m²用 30%戊唑·多菌灵SC 70 mL、43%戊唑醇SC 20 mL、30%苯甲· 丙环唑EC 30 mL、12.5%氟环唑SC50 mL对水稻稻曲病有较好的防效,病穗率防效为73.25%～81.56%,病粒率防效为73.79%～83.68%;4种杀菌剂可在生产上交替轮换使用。

Abstract: Field control efficacy of five fungicides, i.e. 30% Triazole·carbendazim SC, 43% Tebuconazole SC, 30% Benzoyl·propiconazole EC, 12.5% Epoxiconazole SC and 3% Validamycin AS on rice false smut were detected. The results showed that application of 70 ml 30% Triazole·carbendazim SC, 20 ml 43% Tebuconazole SC, 30 ml 30% Benzoyl·propiconazole EC, 50 ml 12.5% Epoxiconazole SC per 667 m² could control rice false smut effectively, and the sick spike control rate was 73.25%-81.56%, sick grain control rate was 73.79%-83.68%. And the above four fungicides could be alternatively used in practice.
