How to use pesticides to cultivate vegetables in winter
As for the harm in vegetable production, manual weeding is laborious and laborious. In vegetable production, most vegetable farmers need to use herbicides. However, there are many varieties of vegetables, short production period, high index of multiple cropping, complicated cornices, and many varieties of herbicides. If they are used improperly, they are likely to cause phytotoxicity and even crop failure. The following describes the use of herbicides in winter vegetable fields. Some points: First, cruciferous vegetable fields: cabbage, radish, live cabbage and cabbage, cauliflower and other seedbeds, can choose 48% trifluralin EC 100-125 ml / mu, 50% large benefits WP 75-1OO G/mu or 20% Napropamide EC 150-200 ml/mu, 33% Weed-cut EC 100-150 ml/mu, add water 40-50 kg/mu, spray evenly on the soil before cruciferous vegetables sowing , Soil moisture is conducive to improving the weeding effect. If there are grasses weeds during the growth period, 12.5% ​​can be used to get 40-60 ml/mu of EC, spray at the weed 2-4 leaf stage. Second, onion and garlic dishes: Garlic field can be used 50% Da Huili WP 100-15O ml / acre or 20% Napropamide EC 200-250 ml / acre, 33% Weeding through EC 150-200 ml / Mu, 25% chlorotoluron WP 300-400 g/mu, add water 40-50 kg/mu, evenly sprayed on the soil surface before seedlings of garlic sowing. Can also be used 25% Echinacea EC 100-150 ml / acre, after the garlic sowing seedlings until the uniform spray, a special effect on the piglet. 23.5% Goer's EC 50-60 ml/mu, evenly sprayed on garlic before sowing to tilling or garlic 2 leaves 1 to multi-leaf and weeds 4 leaves, and the weed control effect is relatively thorough. , but it should be noted that the time of Goer's medication is not available when the garlic is in the needle phase and garlic is in the 1-leaf to 2-leaf period. Post-emergence application, garlic leaves sometimes appear brown or white spots, but does not affect the yield. Third, onion fields: control of grass weeds can be used post-emergence stem and leaf treatment agent, such as grass grass grams, take fluttering net, steady kill, etc.; control broadleaf weeds can use Praxaprozin, Bendazosone and metsyl Chlorine mixture; control single and dicotyledonous weeds mixed, can choose to use grass, fruit Seoul. Usage: 10% chlorpyrifos EC 60-75 ml/mu, add water 40-50 kg/mu, spraying stems and leaves at the 2-4 leaf stage of grass weeds. 50% Praxefine WP 75-100 g/mu and 33% Weeding 150-200 ml/mu. We spray evenly on the soil before or after transplanting the onion. 48% Benzonsone EC is 100-150 ml/mu, which sprays the weed stems and leaves evenly after the onion period of the onion. However, the use of drugs before the 2nd leaf stage will cause phytotoxicity. 23.5% Goer's EC 50-75 ml/mu, sprayed around the live leaf on 3 leaves or 6-10 days after transplanting onions. Fourth, the leek field: seedling leek control grass weeds can use stem and leaf treatment agent to take flaccid net, grass grass g, cover grass can be stable and to kill, such as 12.5% ​​take flutter EC 50-75 ml / mu, in the miscellaneous Grass 2- to 4 leaf stage spray on stems and leaves; broad-leaved weeds and grass weeds can be mixed with 33% of weeding through EC 100-200 ml/mu, add water 40-50 kg/mu, after sowing seedlings of amaranth seedlings Spray evenly on the surface of the soil. In addition to the herbicides used in the above-mentioned seedling leek fields, Laogen agro field can also be used to control gramineous weeds. It can also use 23.5% Goel EC 50-75 ml/mu, add water 40-50 kilograms per mu, and harvest it at Laogen amaranth. Spray the soil before unearthing.
