| 摘 要： | 研究以2年生人工种植乌拉尔甘草为研究材料，通过设置四个处理（CK（清水）、A（35%多.铜WP+40%戊唑醇WP复配剂）、B（10%苯醚甲环唑WG水分散粒剂）、C（25%三唑酮WP））。探究三种不同杀菌剂及组合物对甘草锈病的防效研究。结果表明:在第1次施药后7 d，A处理和B处理的防效分别达64.1%、66.4%；第2次施药后7 d防效分别达69.5%、66.9%，第2次施药后14 d防效分别达68.1%、66.8 %，其对甘草锈病具有较好防效和持续性，而C处理防效较差，3次调查后其防效均低于50%。增产与经济效益评价，与CK相比，A处理与B处理能显著增加甘草的平均产量，增产幅度分别为37.1%、33.4%，新增纯收入分别13 293.00元·hm-2、11 155.20元·hm-2，且A处理的用药成本小于当地农民心理价格区位750元·hm-2,易于推广应用。

| Abstract: | The control effect of different fungicides against licorice rust was studied in this paper, the results showed that the control effect of 35% Copper WP+40% Tebuconazole WP compound and 10% Difenoconazole WG water dispersible granules was was 64.1% and 66.4%, respectively after the 7 days of the first use fungicides, was was 69.5% and 66.9% after 7 days of the second medicine, and was 68.1% and 66.8%, respectively after 14 days of the second use of the fungicides, it had good control effect against licorice rust,however, 25% triadimefon WP had low control effect,it was less than 50% in the periods of 3 time. In yield-increasing and economic benefit evaluation, the average yield under treatment of 35% Copper WP+40% tebuconazole WP compound, 10% difenoconazole WG increased significantly compared with water control, the increase rate was 37.1%, 33.4% ,respectively. The new net income was 13 293.00 yuan ·hm-2 and 11 155.20 yuan ·hm-2 respectively. The cost of copper WG+40% tebuconazole WG formula application was less than the psychological price of local farmers ( lower than 750 yuan ·hm-2), which was easy to be popularized and applied. ; |
