对枣锈病症状、病原和发病规律进行了观察 ,结果表明该病的发生与温度、湿度、间作物及枣树品种等有密切关系。在病害传播感染和再侵染期 ,分别选用 2 5%粉锈宁、50 %甲基托布津和50 %多菌灵等 3种杀菌剂进行田间防治试验 ,结果表明 2 5%粉锈宁对该病的防治效果最好 ,而对照区的病害自然控制率仅为 5.4 % ,防治区红枣株产量由 8kg提高到 36 kg,增长 350 % ,投入产出比为 1∶ 82 ,效果显著 The results showed that the occurrence of the disease was closely related to temperature, humidity, inter-crop and jujube varieties. Three kinds of fungicides, 25% triadimefon, 50% thiophanate-methyl and 50% carbendazim, were selected for field trials in the field of infection and re-infection. The results showed that 25% triadimefon The control effect of natural disease control rate of only 5.4%, jujube plant in the control area increased from 8kg to 36 kg, an increase of 350%, the input-output ratio of 1:82, the effect was significant
