Methods of combating the wasp in the vineyard are mechanical, chemical and folk.
“On an industrial scale, special insecticidal drugs are used, but at home it is quite possible to cope without aggressive chemistry,” the article says.
As a rule, gardeners are used to protect the crop of grids using a grid, which are put on at clusters.
“The material should skip light and air, without creating a greenhouse effect and be dense enough so that the wasp cannot penetrate inside,” the publication noted. “Such covers simultaneously protect against OS, birds and partly from sunburn.”
If there are a lot of bushes, you can immediately cover the entire slope with a garden grid stretched onto the frame.
“This is time -consuming, but effective, especially if the vineyard is open from all sides,” the material noted.
