摘要
68%精甲霜·锰锌水分散粒剂是防治卵菌纲真菌病害的高效、环保型杀菌剂,使用过程中无粉尘,对人体、环境和作物更安全,是新型的水分散性粒剂杀菌剂。田间药效试验结果表明,68%精甲霜.锰锌水分散粒剂1 000倍、800倍、600倍在荔枝挂果期施药3次后,对采收期果实霜疫霉病的防效为65.89%～79.95%,对贮藏期果实霜疫霉病的防效为61.39%～79.07%,显著优于对照药剂80%大生可湿性粉剂600倍的防效,近年作为替代58%甲霜灵.锰锌可湿性粉剂防治荔枝霜疫霉病的药剂,已在广东及邻近省份的荔枝产区推广应用。
68% Metalaxyl-M mancozeb WG is a new highly active fungicide which shows specifically high activity against Peronophythora litchii, the result of tests in fields showed that 68% Metalaxyl-M mancozeb WG using 1：1000, 1：800, 1：600 for 3 times gave a control effect of 65.89% to 79.95% at fruit bearing phase and 61.39% to 79.07% at fruit storing phase against Peronophythora litchii. These results demonstrated that 68% Metalaxyl-M mancozeb WG had a better control effect than 80% Da sheng WP using 1：600, and it was worthy to be popularized on the growing practice in our province.
