尼勒克县是新疆粮食生产基地,每年冬小麦种植面积达30万~35万亩,春小麦种植面积20万~23万亩。近几年本县每年小麦锈病发生面积10万~20万亩,发病田每亩因锈病损失10~60 kg,影响了本县小麦产量及品质。因此探索一套简便有效的防治措施,已成为生产之急需。2013年笔者在尼勒克县进行了4种药剂防治小麦锈病防效试验,现将结果介绍如下。1材料与方法1.1试验设计试验共设5个处理:1)250 g/L丙环唑乳油30mL/亩。2)40%氟硅唑乳油6~8 mL/亩。
Nilka County is the grain production base in Xinjiang, with annual winter wheat planting area of 300,000 to 350,000 mu and spring wheat planting area of 200,000 to 230,000 mu. In recent years, the annual area of wheat rust occurs in an area of 100,000 to 200,000 mu, and the loss of 10 to 60 kg of rust per acre in the affected fields affects the yield and quality of wheat in this county. Therefore, exploring a set of simple and effective prevention and control measures has become an urgent need for production. In 2013, the author carried out four kinds of medicament prevention and control wheat rust prevention and control experiments in Nilik County. The results are as follows. 1 Materials and Methods 1.1 Experimental Design A total of five treatments: 1) 250 g / L propiconazole EC 30mL / mu. 2) 40% flusilazole 6 ~ 8 mL / mu.
