种衣剂在小麦上的应用效果初报

就17%多·克·酮小麦种衣剂对幼苗生长的调控作用以及田间防治甘肃省小麦主要病害的实际应用效果进行了试验研究。盆栽试验结果表明，17%多·克·酮种衣剂安全的药种比为1:50，在此包衣比例下，不仅可提高出苗率，对植株生长无不良影响，而且能使植株根系活力显著增强，叶片叶绿素含量明显提高，生长后期抗倒伏能力增强；田间小区试验结果表明，对早期小麦条锈病的防效可达76.2%、小麦白粉病可达77.0%，对土传性小麦全蚀病的防效可达到82.1%，冬麦区小麦产量提高6.8%，春麦区小麦产量提高10.9%。

Application Effects of 17% Carbendazim Carbofuran Triadimefon Seed Coating formulation on Wheat

Effects of 17% Carbendazim Carbofuran Triadimefon seed coating formulation on growth regulation of wheat seedling and main diseases control were studied in this paper. The results showed that reliable weight ratio of chemical: seed is 1:50 in greenhouse. The germination rate and root activity of coated seeds with this ration were improved significantly as well as chlorophyll content in leaves and lodging resistance. Field tests showed that protect effects on wheat stripe rust and powdery mildew at early stage respectively were 76.2% and 77.0%. And control effect on soil-borne wheat take-all was 82.1%, the increased yield of winter wheat and spring wheat were 6.8% and 10.9% respectively. Meanwhile, the prospect and applications of wheat seed coating formulation were also concisely discussed in this paper.
