| 摘 要： | 试验结果表明,三唑酮对小麦条锈病防病保产效果好,残效期长,用药量低,安全低毒,内吸传导性能强,使用方法多,是目前比较理想的防锈药剂。在小麦初见剑叶及其前后,病叶率在2～4%时,施药较为适合,每亩用药量7～20克。用此法施药一次,平均防病效果在90%以上,保产效果在13.3～36.2%,平均病指压低在3%以下,可控制整个成株期条锈病危害。中、低和超低容量以及淋浇、泼浇的施药效果与常规叶面喷雾的相似,都是可行的方法。三唑酮还可兼治小麦白粉病和叶锈病。

| Abstract: | Triadimefon as a foliage spray on wheat gave excellent control against stripe rust in ourexperiment and behaved as a good systemic fungicide.The suitable period of spraying was the wheat plant just raised their flag leaves and the stripe rust on the start.The suitable dose of spraying was 105 to 300 g (ai) per hectare.When this spraying schedule is followed,one spray would give more than 90% control,and increase in yield 13.3~36.2%.Medium,volume low volume and ultra-low-volume spraying with Triadimefon allgive satisfactory results against stripe rust of wheat. |
