为明确品种抗性和杀菌剂对赤霉病发生及呕吐毒素积累的影响,2022年对8个不同抗性小麦品种和4种杀菌剂防治赤霉病和呕吐毒素进行防效评价。结果表明:在4月10日(扬花株率5%左右)和4月17日2次施药后,200 g/L氟唑菌酰羟胺SC 50 m L/667 m^(2...为明确品种抗性和杀菌剂对赤霉病发生及呕吐毒素积累的影响,2022年对8个不同抗性小麦品种和4种杀菌剂防治赤霉病和呕吐毒素进行防效评价。结果表明:在4月10日(扬花株率5%左右)和4月17日2次施药后,200 g/L氟唑菌酰羟胺SC 50 m L/667 m^(2)+25%丙环唑SC 30 m L/667 m^(2)、40%丙硫菌唑·戊唑醇SC 40 m L/667 m^(2)对赤霉病的防效均在95%左右,25%吡唑醚菌酯SC40 m L/667 m^(2)+27%戊唑·噻霉酮EW 35 m L/667 m^(2)对赤霉病的防效在91%左右,480 g/L氰烯·戊唑醇SC 50 m L/667 m^(2)对赤霉病的防效在84%左右;清水对照区的赤霉病自然发生程度、DON含量及药剂处理区的赤霉病发生程度呈现中感品种>中抗品种>抗性品种趋势。品种抗性和杀菌剂在防治赤霉病过程中存在交互作用,效应量依次为药剂>品种×药剂>品种。结论:利用品种抗性和杀菌剂能够有效控制赤霉病,其协同防效随品种抗性增强而提高;在小麦扬花初期施用氟唑菌酰羟胺、丙硫菌唑、氰烯菌酯等,即使扬花期遇连阴雨天气,可在第1次施药后间隔6~7 d再次施药,也能够保证防效。展开更多
