1. Cruciferous vegetable fields such as cabbage, rape, radish, kale and leeks. Before sowing, spray with 34-80 g/mu of trifluralin pure drug , and mix with soil and sow. 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. Umbelliferous vegetable fields such as celery, coriander and carrot. Controlling weeds in seedling stage is the key to chemical weeding in this kind of vegetable field. It is mainly used to control the weeds of annual grasses with 37-80 g/mu of fluridine pure drug before sowing. 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 planted before the planting with 40-60 g/mu of fluridine, 50-80 g/mu of dimethoate, 50-60 g/mu of dimethoprim. 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. Liliaceae vegetable fields such as onions, leeks and garlic. Before sowing or after sowing, use Ligulong 60-130 g/mu before the seedling, 60-130 g/mu for the grass, and 40-80 g/mu for the Lele. 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.
