为筛选有效防控番茄灰霉病的药剂,设置了 5种不同药剂处理,调查其对番茄灰霉病的防控效果,以及对番茄产量的影响.结果表明,各药剂处理均对灰霉病表现出一定的控制效果,其中以吡噻菌胺、啶酰菌胺处理的防效均较好,叶部病害防效超过80%,果部病害防效也超过80%,均显著高于其他药剂;从产量上来看,吡噻菌胺、啶酰菌胺处理的增产率均超过20%,可以作为灰霉病防控药剂的首选.
In order to select highly effective fungicides to control the tomato gray mold,5 treatments were setted,aiming to test the control efficiency against tomato gray mold and the influence to yield,using clear water as a control.The result showed that all treatments had control effect at different level except CK.The control effects of penthiopyrad and boscalid were better,with leaf disease control effects exceeding 80%and fruit disease control effects also exceeding 80%,all significantly higher than other pesticides.The increase rate of penthiopyrad and boscalid were more 20%,so the two fungicides were the first selection to control the disease in the future.
