不同药剂处理对大樱桃流胶病的防治效果比较

为有效控制大樱桃流胶病的发生与危害,试验设计了7种不同药剂处理对大樱桃流胶病的防治效果进行评价。结果表明,在单剂中防效最好的是6%春雷霉素AS,2次防效调查结果分别为28.42%和50.20%,3%中生菌素WP与石硫合剂的防效也均超过30%,80%代森锰锌WP2次防效调查结果分别为22.02%和17.01%,有下降趋势。在复配混剂中,3%中生菌素WP与6%春雷霉素AS组合对流胶病防治效果最好,2次防效调查结果分别是42.22%和63.25%;其他2种处理防效较差,其中3%中生菌素WP和80%代森锰锌WP混用的防效仅达到10.75%和25.69%。

Comparison of the Controlling Effects of Different Chemical Agents against Cherry Gummosis

In order to effectively control the occurrence and damage of cherry gummosis, the experiment was designed to evaluate the effectiveness of seven different agent treatments on the control of runny cherry disease. The results showed that among the single agents, the best efficacy was achieved by 6% kasugamycin AS, with 28.42% and 50.20% efficacy in two treatments, respectively, while the efficacy of 3% zhongshengmycin WP and lime sulfur also exceeded 30%. The results of 80% Mancozeb WP were 22.02% and 17.01% respectively, with a decreasing trend. Among the compound mixes, the combination of 3% zhongshengmycin WP and 6% kasugamycin AS was the most effective against gummosis, with the results of the two control surveys being 42.22% and 63.25% respectively; the other two treatments were less effective, with the mixture of 3% zhongshengmycin WP and 80% Mancozeb WP reaching only 10.75% and 25.69%.
