Aquatic vegetables mainly include alfalfa, alfalfa, alfalfa, sage, rhizome and cress. Weeds in aquatic vegetable fields are different from weeds in dryland vegetable fields. In addition to some wet weeds such as calves in the past few years, there are mainly weeds, ragweed, sedge, melon grass, and eyes. Aquatic weeds such as vegetables, water sedge, flat poles, and valerian are very similar in species to rice field weeds.
Aquatic vegetables are more resistant to chemicals, and various herbicides that control weeds in rice fields are safer.
Commonly used herbicides (before weeds are used):
1, 60% butachlor EC. 75-100ml per acre, 30 kg of water spray.
2, 12% oxacillin EC. Use 125-150ml per acre and spray 30kg with water.
3, 10% of agricultural WP can be 15-25 grams per acre, 25 kilograms of water spray, to control broadleaf weeds and annual sedge weeds, the agent is very significant.
4, when the farm is mixed with butachlor and other acaricides (the amount is 1/2-1/3 of each), it can prevent almost all weeds in the aquatic vegetable field.
Note: The whole field requires flatness; the herbicide should be kept for 2-3 days of shallow water.
