Can you use herbicides in walnut orchard?

It's possible. The second stage of glyphosate, but be sure to pay attention to the weather when spraying, and try to ensure that it doesn't rain for a while after spraying. If it rains, herbicides will invade the soil and damage the roots. And don't beat the leaves. We used herbicides at this time last year, and some of them went wrong. There are just new buds this year, and there are very obvious symptoms. The leaves are yellow, red and wrinkled. I wonder if they will die this year. The application effect of herbicides is really good, at least there are fewer weeds this year.
