Vegetables can be well-replenished with many trace elements missing in the human body, so they are very popular. In the process of growing vegetables, especially in summer, there will be a lot of weeds. How should we choose herbicides in summer vegetable fields? This article will introduce you to the selection method of summer vegetable field herbicides.
(1) Brassica vegetable fields such as cabbage, rape, radish, kale and leeks are sprayed with trifluralin pure drug 37-80 g/mu before sowing. After sowing, the seedlings can be used 100-130 g/mu of pure medicine and 50-90 g/mu of acetochlor. After emergence, in the weeds 3-5 leaf stage, the application of catching net, stabilizing, grass, grass and grass can spray the stems and leaves, which can prevent grass weeds.
(2) The umbelliferous vegetable fields such as celery, coriander and carrot are controlled to control the weeds in the seedling stage. This is the key to chemical weeding in this kind of vegetable field. It is mainly used to fertilize the pure drug 37-80 g/mu to the water before sowing. After the spraying, the soil mixing method is used to control the annual grass weeds. After sowing, the herbicide ether pure drug 200-250 g/mu spray can be used, or the application of 125-150 g/mu pure drug spray can be used to control broadleaf weeds and grass weeds. The carrot field can also be used in the pre-emergence seedlings with 200-330 g/mu of habitat pure drug and 130-260 g/mu of leguminous. After the vegetables are emerged, they can be used for catching, stabilizing, grass, grass and grass.
(3) Solanaceae vegetable fields such as pepper, tomato, eggplant and potato. Generally, eggplant, tomato and pepper can be used 40-60 g/mu, and the amount of dimethoate 50-80 g/mu. Le Ling 50-60 g / a spray sprayed with soil after planting. After planting, spray it with netting, stabilizing, etc. The potato can be used 200-300 g/mu of propionate before transplanting. After planting the soil, it can be planted. After transplanting, it can be supplemented with 125-150 g/mu and 120-230 g/mu. Before emergence, 30-50 g/mu of paraquat pure drug or 60-100 g/mu of glyphosate can be used to eliminate all weeds before emergence.
(4) Forage, vegetable such as onion, leeks and garlic, before or after sowing, use Ligulong 60-130 g/mu before the seedling, 60-130 g/mu for the grass, 40-80 g of the Leto /mu. After emergence, you can use the net, grass, grass and grass. When the old root leeks are harvested and the new leaves are raised after each harvest, the weeds can be used to prevent weeds.
