温室盆栽及田间小区试验结果表明,速保利(Diniconazole)对防治小麦条锈病有优异的保护作用和治疗作用。该剂叶面施用后保护活性持续50d以上,能有效地防止条锈菌侵染和降低反应型。潜育期施药能中断侵染,铲除叶内菌丝体,在显症或产孢后施药,能使已有病斑褐变枯死,有效地抑制再侵染。田间适期喷药有很高的防治效果和保产效果,用药量略低于三唑酮。
The results of greenhouse potted plants and field plots showed that Diniconazole had excellent protective and therapeutic effects against wheat stripe rust. After the foliar application, the protective activity lasts more than 50d, which can effectively prevent stripe rust infection and reduce the reaction type. Potential application of pesticides can interrupt the infection, eradication of mycelium in the leaves, in the disease or sporulation after spraying, can make the brown spot lesions have been withered, effectively inhibit reinfection. Spraying during the field has a very high control effect and the effect of yield, dosage slightly lower than triadimefon.
