What is the harm of herbicide spraying on vegetables?

Herbicide spraying on vegetables will cause harm to vegetables, mainly in the following aspects:

1.Pesticide damage: Harmful chemicals in herbicides can penetrate the soil layer and invade the water source and soil environment, making the soil useless to use, causing long-term pollution problems.

If sprayed on vegetables, pesticide damage will cause vegetable stems and leaves to be deformed, twisted and curled, wrinkled and shrunk, leaves turn yellow or black-green, and in severe cases, fallen leaves, growth points shriveled and necrotic, resulting in dead trees and dead seedlings.

2.Residue hazards: Spraying herbicides on vegetables will cause pesticide residues, and long-term consumption of vegetables containing pesticide residues will cause harm to human health, and may lead to cancer in severe cases.

3.Accidental spraying: If herbicides are sprayed on vegetables by mistake, it may lead to accidental ingestion or misplanting, which will affect human health and planting efficiency.

Therefore, in order to reduce the harm of herbicides to vegetables, pesticides should be applied away from vegetables and avoid spraying on vegetables. At the same time, after buying back vegetables, they should be properly stored and washed frequently to reduce pesticide residues.

The answer is different, depending on the situation.

If biocidal herbicides such as glyphosate and glufosinate are used, then the vegetables will die quickly.

If different herbicides are used for different vegetable varieties, then there will be no harm to the vegetables. However, it is important to harvest the market after the safe interval. Otherwise, it is poisonous, and after people eat it, it is not conducive to physical health, and even poisoning.

Sprayed with herbicide.

The vegetables can not be eaten.

Herbicides contain carcinogenic substances, and vegetables absorb this poison. Not only are vegetables not cleaned to be harmful to our health, but they can also cause symptoms of poisoning if eaten wrong, so we must pay special attention to be careful.

Herbicide spraying on vegetables will kill the vegetables within a few days, and no animal can eat them because there is residual herbicide on the dead vegetables.

1. Eat leafy vegetables.

For example, cabbage, cabbage, green leafy vegetables, such as Chinese cabbage, camellia, cauliflower, cabbage, celery, lettuce, artemisia, spinach, bracken, amaranth, coriander, etc. The use of herbicides is not recommended for this type of vegetables. If necessary, Dahuili and weeding can be used for soil treatment before seedlings after sowing (celery and lettuce should not be used for Dahuili) or Guoer, weeding, and vegetable Zhuang No. 2 can be used for soil treatment before planting.

Celery seedling field can be used for soil treatment before seedling sowing with dilodiamine, gol and dioxazim; Lettuce and vegetables can be treated with Guoer, weedin, and Vegetable Zhuang No. 2 in the soil before planting; Artemisia annua and amaranth can be treated with pre-seedling soil after weeding and sowing; Spinach plots that do not have wells around can be used for chlorpyra; Coriander dididilamine is treated with pre-seedling soil treatment, and sulfonylurea herbicides can not be used in this kind of vegetable field in the previous crop, and acetochlor cannot be used in spinach.

2. Liliaceae, root vegetables, potato vegetables.

For example, leeks, garlic, green onions, onions, lilies, garlic, carrots, kohlrabi, potatoes, ginger, yams, etc. Leeks have a short growth period, frequent harvesting, and eat leaves, try not to use herbicides, and if necessary, you can choose to kill the slightly toxic herbicide Guoer, and spray the old leeks after harvesting.

Garlic, lily, potato, ginger, yam has a long growth period, and is mainly edible bulbs and tubers, (garlic edible garlic moss) can be soil treatment in the early growth stage or stem and leaf treatment in the early post-emergence stage, you can use fruit, garlic grass ether, vegetable Zhuang No. 2, etc. Green garlic, green onions, and onions have a short growth period, and can only be used with contact soil treatment agents; Radish and carrot can be treated with herbicides with poor conductivity, such as weeding.

3. Nightshade vegetables.

For example, eggplant, tomato, pepper and other vegetables should not use stem and leaf treatment agents, and before transplanting, you can choose to use contact soil treatment agents such as Ruoer, oxazil or vegetable Zhuang No. 2 and dilometin with a slight systemic conduction effect.

For example, cucumber, pumpkin, winter melon, loofah, vegetable melon, bitter gourd, bergamot, horn gourd, etc. It is strictly forbidden to use acetochlor in this kind of vegetables, and it is advisable to use herbicide, Guoer, and dioxapyrin for soil treatment after sowing.

5. Legumes and vegetables.

For example, kidney beans, cowpeas, raw edamame, peas, broad beans, lentils, etc. There are many herbicides suitable for vegetable applications, but soil treatment herbicides are still the first choice, such as dilodiamine, vegetable Zhuang No. 1, dioxazim and other post-sowing pre-seedling soil treatments.

6. Aquatic vegetables.

For example, lotus root, cocoon white, mushrooms, etc. Try not to use herbicides for aquatic vegetables, and if necessary, you can choose low-toxicity Lianzhuang No. 1, grass buster, etc.

7. Special vegetables.

For example, asparagus, burdock, lettuce, artichokes, ginger, camellia, maran, chrysanthemum brain, etc. Fruit can be used for soil treatment after sowing and before budding or before transplanting.

Spraying herbicides on vegetables has the potential to cause them to die.

If you spray it directly on the dish and eat it, you may be poisoned.

The herbicide is sprayed on the vegetables and it takes at least 10 days to pick.

Precautions for herbicide use:

First, according to the field crops and control objects, the corresponding herbicides are used, such as corn fields, and herbicides used in corn fields should be selected; Crops used before seedlings cannot be used for post-seedling application; Soil treatment should not be used for stem and leaf treatment, and at the same time, the safety of the crop should be considered.

The second is to strictly implement the dosage standards specified in the herbicide instruction manual, and the dosage shall not be increased at will.

Third, if two or more herbicides are used at the same time, different herbicidal spectrums must be selected, but the applicable crops, periods and usage methods must be consistent; When wettable powder is mixed with emulsifiable concentrate, the wettable powder should be dissolved in a small amount of water to make the mother liquor, and then emulsifiable concentrate should be added; When dispensing the solution, first fill the semi-nebulizer water, then add the mother liquor, and add enough water.

Fourth, in strict accordance with the period specified in the instructions for timely use, which is suitable for pre-sowing treatment of soil, just before sowing, suitable for sowing before seedlings, just before sowing seedlings; If it is suitable for stem and leaf treatment, it should be avoided during the sensitive period of crops. The right time is to choose a sunny and windless weather to take medicine, and avoid high temperature, humidity or windy weather to prevent drug damage or reduce the efficacy of the drug.

Fifth, when spraying herbicides, it is necessary to operate carefully, the walking speed is uniform and appropriate, the working pressure of the sprayer is stable and moderate, the stubble pressing in the field is accurate, and the spraying is not re-sprayed, so as to be uniform and consistent.

Sixth, clean the pesticide application equipment in time, spray herbicide sprayers and other utensils, and clean them with alkaline water in time after use, so as to prevent pesticide damage in other crop fields, and use special sprayers.
