摘要
以花椒提取物为供试药剂,以20%粉锈宁可湿性粉剂为标准药剂对照,在室内对盆栽小麦叶锈病进行防效试验研究。结果表明,花椒提取物对小麦叶锈病具有一定的保护防效和治疗防效。不同浓度的花椒提取物具有不同的防效,存在显著差异性。随着花椒提取液浓度的增大,保护防效和治疗防效随之增强。相同浓度的花椒提取液对小麦叶锈病的保护防效和治疗防效也存在差异,保护防效高于同浓度的治疗防效。当提取液的浓度为40mg/mL时,对小麦叶锈病的保护防效和治疗防效分别为72.15%和63.76%。
The control effect on wheat leaf rust of Zanthoxylum extracts were conducted indoor, with 20 % triadimefon WP as the standard chem- ical agent. The results showed that Zanthoxylum extracts to wheat leaf rust had a protective effect and treatment control effect. Different concentrations of Zanthoxylum extracts had different control effects. With the increase of concentration of the extracts of Zanthoxylum, protective effect and control effect were enhanced. At the same concentration of Zanthoxylum extracts,protective effect and control effect to wheat leaf rust were also different, which protective effect was higher than control effect. When the concentration of the extract was 40mg/mL, the protective effect and control effect to wheat leaf rust were 72.15 % and 63.76 % respectively.
