豆角开的花被虫子吃了怎么办

[yhy192]

豆角苗长得很快，花也开的很好，但是虫子把花给吃完了，一个豆角也没长，不确定是什么虫子吃的花，好像是蚂蚁，看到架子和豆角藤上有许多蚂蚁，有没有好办法防止虫子吃花？

我的豆角叶也是被一种黑色的像篬蝇样的虫子咬的一踏糊涂,没办法,只好用'雷达'轻喷了一下,好在豆角结的还没大批开始,希望多下雨冲冲,摘的时候多用水泡泡.没有办法的办法.

试一试用洗碗液+水（1:5）喷一喷，可以防止虫害的

Are you sure?

1:5吗?

我试过10ML兑4L水还烧伤了秧苗.

not so sure, it some where between 1:5 to 10. I didn't measure it, but definitely no more then 1:10. Didn't see any damage.

**** Google a little more, looks like 2% is most recommended (rang from one cup of soap to 1 to 3 tablespoons per gallon )*******

Why do you need 4L? You use a spray bottle, like 500 ml, to spray the mix onto the plant, like any other pesticide. Did you water the plant with the mix?

I googled that formula to treat earwig.
My spray can is 4L.

多谢各位， 准备试试2%的洗碗液，看能不能保住几个豆角。
