在小麦进入灌浆中、后期,分别于小麦籽粒形成初期及乳熟初期各施药1次,或在乳熟初期施药1次,每667m2用25%苯醚甲环唑EC 20~30 mL,对小麦叶枯病、叶锈病、秆锈病、颖枯病具有较好的防治效果,其防治效果达89.72%~97.46%,千粒重增加4.06~5.51 g,每667 m2产量增加45.61~62.46 kg、增产7.94%~10.88%,小麦茎、叶、穗的光合作用时间延长,防病、增产作用显著。 In the early stage of wheat grain filling and in the early stage of wheat ripening, the wheat grains were inoculated one time respectively or in the early stage of milky ripening. Each 667m2 was treated with 25% difenoconazole EC 20 ~ 30 mL, It has good control effects on wheat leaf blight, leaf rust, stem rust, and septoria. The control effect is 89.72% -97.46%, the thousand-grain weight is increased by 4.06-5.51 g, the yield per 667 m2 is increased by 45.61-62.46 kg, 7.94% ~ 10.88%. The photosynthesis of wheat stem, leaf and spike prolonged, preventing disease and increasing yield.
