Is it okay to hit vegetables with a watering can that has been sprayed with herbicide Is there any s

It's okay to spray vegetables with a herbicide sprayer, but there are a few things to keep in mind:

1.Cleaning the sprayer: The sprayer must be cleaned before spraying other pesticides. It can be rinsed several times with clean water to ensure that the residual herbicide is completely removed.

2.Use alkaline substances: If the sprayer is used to spray herbicides, it is best to use an alkaline substance such as baking soda or laundry detergent to clean it. Pour these substances into a sprayer, add an appropriate amount of water to dissolve well, then gently shake and thoroughly clean the sprinkler head and water pipe.

3.Timely spraying: After spraying pesticides, vegetables should be sprayed with water in time to remove residual pesticides on the foliage. This reduces the concentration of herbicides in the crop and reduces the adhesion of toxic substances.

4.Strengthen fertilizer and water management: If crops are affected by mild pesticides, fertilizer and water management can be strengthened to promote the recovery of crop growth. This includes measures such as timely irrigation and foliar fertiliser.

5.Use of antidote or corresponding remedy: If the damage is severe, the antidote or corresponding remedial agent can be used to reduce the damage. For example, ferrous sulfate can reduce the pesticide damage of gram traces to wheat, and calcium polysulfide can make the residual simazine activity in the soil disappear.

In conclusion, it is okay to spray vegetables with a herbicide sprayer, but you need to pay attention to the above points to ensure the safety and health of vegetables.

The sprayer sprayed with herbicides.

In the future, if you want to spray other pesticides, you must clean them first, otherwise there will be pesticide damage. The cleaning of the sprayer is also relatively simple, and it can be rinsed several times directly with clean water. If you are spraying pesticides on vegetables, it is better to use baking soda.

Or laundry detergent.

and other alkaline substances to rinse. Pour an appropriate amount of baking soda into the sprayer, then add an appropriate amount of water, let it fully dissolve, shake it gently a few times, and clean the sprayer's nozzle and water hose thoroughly. After doing this, rinse it with clean water a few more times.

The solution to the accidental spraying of herbicides on vegetables is as follows:

1. Spray with water in time: remove foliar residues, reduce the concentration of herbicides in crops, and reduce the poisons attached to the leaves. Or combined with drainage and lime to neutralize the acidic herbicides in the field, and timely irrigation to promote the transpiration of wheat and reduce the pesticide damage.

For the pesticide damage on the plant, the toxic residues on the plant can be washed away by sprinkler irrigation machinery or spraying equipment. Field irrigation water can also be used, which can be continuously irrigated with fresh water.

2. Strengthen fertilizer and water management: when the pesticide damage is mild, some leaves of crops appear brown spots, and the heart leaves are not dead. When it is clear that the herbicide is sprayed at too large a dose, recovery can generally be achieved within a short period of time.

3. Spraying antidote or corresponding remedy: ferrous sulfate can reduce the pesticide damage of gram traces to wheat; Calcium polysulfide can make the residual simazine activity in the soil disappear; Foliar fertilizer can be sprayed to promote the rapid recovery of crop growth to reduce pesticide damage; Part of the leaf loss can be compensated by strengthening fertilizer and water management; Gibberellin was sprayed to reduce the damage of auxin herbicides.

Cleaning is required. Cleaning Method:

1. Soak in light salt water: first rinse with water at least 3 to 6 times, then soak in light salt water, and then rinse with water 1 time. For cabbage vegetables, you can cut them first, soak them in clean water for 1 to 2 hours, and then rinse them with water to remove residual pesticides.

2. Wash with dish soap: dilute the dish soap to 300 times and wash it once, and then rinse it with water 1 to 2 times, which can remove germs, insect eggs and residual pesticides on vegetables.

3. Soak in boiling water: The best way to remove some residual pesticides is to scald, such as green peppers, cauliflower, beans, celery, etc., and it is best to scald it with boiling water before putting it into the pot. This method can remove 90% of the pesticide residue.

Summary. There are many types of herbicides, depending on what herbicide you are appliing, if you apply glyphosate, it will be absorbed through the vegetable leaf stem, the roots will die, the vegetables will die, if it is paraquat, then look at the amount applied, if the amount is large, the vegetables will die, if the amount is not large, then sprinkled to **, ** will produce spots, will not cause the whole vegetable to die. If it is a selective herbicide, it depends on whether the vegetable is broad-leaved or grassy, if the vegetable is broad-leaved, then use a gramineous herbicide, if it is a grassy vegetable, choose to use a broad-leaved herbicide.

Herbicide sprayed on vegetable crops, what to do.

There are many types of herbicides, depending on what herbicide you are applying, if the round application is glyphosate orange surplus, then absorbed through the vegetable leaf stem, the root will die, the vegetable will also die, if it is paraquat, then look at the amount of mold, if the amount is large, the vegetable will die, if the amount is not large, then sprinkled to **, ** will produce spots, will not cause the whole vegetable to die. If it is a selective herbicide, it depends on whether the vegetable is broad-leaved or grassy, if the vegetable is broad-leaved, then use a gramineous herbicide, if it is a grassy vegetable, choose to use a broad-leaved herbicide.

The general symptoms of harm are deformed, twisted and curled of vegetable stems and leaves; or shrunken and shriveled, and the leaves turn yellow or black-green; In severe cases, the leaves fall and the growth point shrinks and dies, resulting in dead seedlings. The main damage modes of herbicides in vegetable fields are residual hazards, fumigation hazards and accidental spraying. Herbicide pesticide damage directly affects the normal growth and development of vegetables, so the production of the sedan car is reduced, and in serious cases, the harvest is even destroyed.

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.
