How do aquatic vegetables use herbicides?

How do aquatic vegetables use herbicides? Please guide the main aquatic vegetables are water chestnut, lotus root, Zizania caduciflora, Cigu, Ling, celery and so on. The weeds in aquatic vegetable fields are different from those in dryland vegetable fields. In addition to some wet weeds such as carp intestines in the past few years, there are mainly aquatic weeds such as paspalum grass, Hedyotis diffusa, special-shaped sedge, melon bark grass, eye vegetable, water sedge, flat pole,  grass and so on, which are very similar to those in paddy field. Aquatic vegetables have strong drug resistance, and all kinds of herbicides to control weeds in paddy fields are safe for them. Common herbicides are (used before weeds sprout): 1. 60% butachlor EC. 75-100ml per mu, spray with 30kg of water. 2. 12% chlorpromazine EC. Use 125-150ml per mu and spray 30kg of water. 3. 10% of Nongde wettable powder is 15ml 25g per mu and sprayed with 25kg water to control broad-leaved weeds and annual Cyperaceae weeds. 4. When Nongdeli was mixed with barnyardite and other paspalum fungicides (the dosage was 1max, 2mer, 1pm, respectively), it could control almost all the weeds in aquatic vegetable fields. Note: the field should be leveled, and the shallow water layer should be kept for 3 days during the application of herbicides.
