                甜瓜叶片边缘有干枯灰白色病斑、黄色斑点是病,怎么防治?

                2020-06-12 15:14:51  来源:互联网  次阅读

                菜农咨询:甜瓜叶片边缘有干枯病斑,有的叶柄和叶片腐烂,病斑呈灰白色,有黄色斑点,请问这是什么情况?该怎样防治?

                解答:根据描述疑似细菌性腐烂病和疫病,也有蔓枯病和小黄点靶斑病。应该统筹兼顾,综合防治,首先考虑防治主要病害,你的温室甜瓜疫病和霜霉病较多,又是传播侵染性最快的病害,这应是首先防治的,可以用甲霜灵加普力克加春雷王铜喷施1次。间隔3-5天后,再喷施健达、健功、健武、露娜森、绿妃任一种加苯醚甲环唑加春雷噻唑锌喷雾1-2次,重点防治蔓枯病和靶斑病,兼治细菌性病害。
