Application of glyphosate in vegetable field

(agricultural Wealth Network) "can glyphosate, a biocide herbicide, be used in vegetable fields?" Some farmers have been wondering about this problem. The answer is yes, but we should pay special attention to the use of technology, otherwise it is easy to cause drug damage to vegetables!

Glyphosate, also known as Nongda, Zhencaoning, Nongle, etc., belongs to organophosphorus herbicides, and its active ingredient is glyphosate. It has a broad-spectrum herbicidal effect on weeds, which can be used in stem and leaf treatment, and can kill the underground part of perennial deep-root weeds, but it will fail quickly when it comes to soil, and it is ineffective to unearthed weeds.

The use of glyphosate, general weeds and other weeds, 4-6 leaf stage, with 10% water agent 0.5-1 kg per mu, add 100 ml of diesel oil, add about 20-30 kg of water, evenly spray weed stems and leaves.

Glyphosate is used for weeding in vegetable plots. It can only be used when there are no vegetables in the vegetable field. 10% water agent 0.5 kilogram per mu can be used to kill weeds such as Magnolia mandshurica, Kentucky bluegrass, amaranth and wild peas. Use 10% water agent 1 to 1.5 kg to kill weeds such as aconite, plantain, Euphorbia angustifolia and so on. 2.5 kg of 10% water agent was used to kill weeds such as white grass, Reed, plow grass, half-hedgehog, dog bud root, Pinellia ternata and so on. All of them are sprayed on 60 kilograms of water and spray on the whole field.

When dealing with the stems and leaves of weeds, it is strictly forbidden to make the liquid come into contact with vegetables and other crops to prevent drug damage.

When killing weeds in leek fields, 41% Roundup water agent should be used on the day after the leek harvest (not put off until the next day), and 0.2 liters of water agent should be used in the land dominated by annual weeds. In the land dominated by perennial weeds, 0.3 liters of water agent was used and 30 kilograms of water was sprayed throughout the field.

When killing weeds in the field of cauliflower, 10% water agent 1kg to 2kg, 50 kg to water and spray to the whole field can kill weeds such as white grass, paspalum, dog bud root, yellow (purple) Cyperus and other weeds. Safe for cauliflower.

When spraying, the effect of 0.8 mm aperture sprinkler is better than that of 1.0 mm aperture sprinkler. The medicament is effective only after touching the stem and leaf. Spray it evenly and let the weeds adhere to the medicament.

The medicine solution is prepared with low hardness water, and the used sprayer should be cleaned repeatedly to avoid causing drug damage to other crops when used in the future. It is not suitable to be mixed with quick-acting herbicides such as dimethyltetrachloride and gram. If 0.1% washing powder is added to glyphosate, or 30 grams of diesel oil per mu, the efficacy can be enhanced.
