How to properly choose herbicides for vegetable cultivation

Protected cultivation of vegetables

(1) Plastic film cultivation: The herbicides selected before transplanting are 48% trifluralin emulsifiable concentrate, 50% chlorpyrifos WP, 50% acetochlor EC, 24% geran emulsifiable concentrate, and 33% weeding emulsifiable concentrate. , 72% dur emulsifiable concentrate, 50% dichlorfen wettable powder, 60% butachlor EC, 12.5% ​​oxacillin EC. (2) greenhouse cultivation: due to the high temperature and humidity in the greenhouse, the shed is not airtight. Most herbicides often cause phytotoxicity in the greenhouse, and the weeds in greenhouse vegetables are particularly harmful. Therefore, greenhouse vegetable chemistry For weeding work, it is still necessary to actively explore the application of herbicides , safe use of dosage and safe application period.

Transplanting vegetables

Transplanted vegetables are transplanted to the field after the seedling stage, so the tolerance to herbicides is strong. For soil treatment before transplanting or for controlling weeds before transplanting, consider the following herbicides: 33% weeding emulsifiable concentrate, 48% trifluralin emulsifiable concentrate, 50% chlorpyrifos WP, 50% ace Amine EC, 24% Gore EC, 72% Duer EC, 50% dichlorfen wettable powder, 60% butachlor EC, 41% glyphosate water, 20% paraquat, 12.5% ​​oxalo Ling cream and so on. However, melons, especially cucumbers, are sensitive to most herbicides and must be taken care of.

All kinds of broad-leaved vegetables, 5% fine grass emulsifiable concentrate, 12% yuetong emulsifiable concentrate, 4% spray emulsifiable concentrate, 10.8% high-efficiency grass emulsifiable concentrate, 12.5% ​​catching net and other stem and leaf treatment agents are very safe for broad-leaved plants. It has excellent control effect on grass weeds and can be widely used in broadleaf vegetables to control a variety of grass weeds.

Small seeds, live vegetables or seedbeds

Such vegetables are more sensitive to herbicides, and many herbicides that can be used to transplant vegetables may affect the emergence of such vegetables, and even die after emergence. Herbicides which can be used in such vegetables are 33% weeding emulsifiable concentrate, 50% dichlorpyrifos wettable powder and 50% acetochlor emulsifiable concentrate. Vegetables with large seeds or vegetative organs can be used for the selection of the herbicides and the choice of time difference, and the resistance to herbicides is enhanced. The herbicide for soil treatment before or after sowing and before seedling is 33% weeding emulsifiable concentrate, 48% trifluralin emulsifiable concentrate, 50% chlorpyrifos WP, 50% acetochlor emulsifiable concentrate, 24% geran emulsifiable concentrate , 72% dur emulsifiable concentrate, 50% big benefit WP, 60% butachlor EC, 12.5% ​​oxacillin emulsion.

Aquatic vegetables

The herbicide which can be used to control weeds in such vegetable fields is 50% chlorpyrifos WP, 60% butachlor emulsifiable concentrate, 12.5% ​​oxacillin emulsifiable concentrate, 24% geran emulsifiable concentrate, and 10% nectar wettable powder. Wait.

No-tillage weeding

Recommended use: 20% gram, 20% glyphosate, 20% Saida, 41% Roundup, 20% gram grass fast.

Recommended for weeding in rapeseed field: high-efficiency grass cover, Weiba, Jinghecaoke, catching net, collecting music, spray, fine killing, high Turk, good health, Aijie, NP-61 (speed Capture net) and so on.
