摘要
水稻稻曲病是水稻生产上一种重要的真菌病害,近年发生严重。本试验选用30%爱苗EC(有效成分组成为:15%丙环唑+15%苯醚甲环唑)等7种不同杀菌剂在不同时期对水稻稻曲病进行了防治试验,以期为指导水稻生产上防治水稻稻曲病,正确选用药剂提供科学依据。结果表明,在破口前5～7d的施药防效普遍高于在始穗期的防效,其中30%爱苗EC15mL/667m2处理和20%井冈霉素SP6.5g/667m2处理的防治效果较好,均达到70%左右,而50%多菌灵WP62.5g/667m2处理的防效在所有处理中防效最低,仅在30%左右,且差异显著。
Ustilaginoidea virens is one of the important fungicidal diseases on the rice and damaging seriously in recent years. The efficacies of 7 fungicides, including 30% Armure EC （consitituted of 15% propiconazole and 15% difenconazole） and so on, were detected in field. The results indicated that the efficacies of 7 fungicides on RFS before 5 to 7 days spraying in crevasse were better than those of beginning tasseling. The efficacies of 30% Armure EC with 15 mL/667m^2 and 20% jingangmycin SP with 6.5 g/667m^2 on RFS were ideal and about 70%. However, the efficacy of 50% carbendazim WP was lowest and only about 30% and had significant diference with other treatments.
