Vegetables that have been sprayed with pesticides can be eaten for a few days, and greens can be eat

The pesticide is a high-efficiency, broad-spectrum, contact and systemic insecticide, which is suitable for killing mouth-sucking pests such as aphids, spider mites, thrips, etc., as well as lepidopteran larvae and beetles. Dimethoate is a common organophosphorus pesticide that is easily absorbed by plants and transported to the whole plant. Rice can be used to control pests such as rice leafhoppers, rice planthoppers, and rice thrips.

50 ml of 50% EC can be used with 75-100 kg of water for spray control. 1.What kind of insects are dimethoate pesticides suitable for?

1.Dimethoate pesticide is a highly efficient, broad-spectrum, contact and systemic insecticidal insecticide, suitable for the control of mouthpart pests, as well as lepidopteran larvae and beetles, such as aphids, red spiders, thrips, fruit flies and other pests. 2.

Dimethoate is a common organophosphorus pesticide that is easily absorbed by plants and transported to the whole plant. It is relatively stable in acidic solution, and will be rapidly hydrolyzed in alkaline solution, so it cannot be mixed with alkaline pesticides. 3.

When controlling rice pests, such as rice leafhoppers, rice planthoppers, rice thrips, etc. , 75 ml of 40% dimethoate emulsion or 50 ml of 50% emulsion can be used per mu to add 75-100 kg of water for spray control. 4.

When controlling vegetable pests, such as vegetable aphids, pea leaf miners and other pests, 50 ml of 40% emulsifiable concentrate can be used per mu, and then 60-80 kg of water can be added for spray control. Second, dimethoate pesticides can be eaten in a few days. 1.

Generally, dimethoate pesticides should wait at least 7 days before eating. If you are not in a hurry, it is better to wait 10-15 days. Soak the picked vegetables in baking soda for about 10 minutes and then wash them.

2.Dimethoate pesticides are very toxic to the stomach of cattle and sheep. Green manure and weeds that have been sprayed with pesticides cannot be fed to cattle and sheep within a month, and cattle and sheep cannot be grazed within 7-10 days in places where pesticides have been applied, which is more toxic to the stomach of poultry.

When applying dimethoate pesticides, it is necessary to avoid pesticide damage. 3.The pesticide can not be used before the harvest of vegetables, the dimethoate pesticide is easy to cause pesticide damage to plum blossoms, cherry blossoms, apricots, peaches, and flowers and trees such as Asteraceae, figs, and citrus are sensitive to diluted dimethoate emulsions of less than 1500 times.

Therefore, it is necessary to test before use to avoid pesticide damage. 4.In the case of dimethoate pesticide poisoning, potassium permanganate should not be used for gastric lavage, because potassium permanganate can oxidize dimethoate into a more toxic substance.

It takes 7-15 days to eat a dish that has been sprayed with pesticides, if the concentration of pesticides is small, it can be picked and eaten in about 7 days, and if the concentration is relatively large, it takes about 15 days to eat. It is recommended to soak the pesticide dish in salt water for about 10 minutes before eating it, which can effectively remove the residual pesticides.

Pesticide. <>

Pesticides refer to chemical agents used in agriculture to prevent and control pests and diseases and regulate plant growth, and are widely used in agriculture, forestry and animal husbandry production, environmental and household health pest control and epidemic prevention, industrial product mildew prevention and moth prevention.

There are many varieties of pesticides, which can be mainly divided into insecticides, acaricides, rodenticides, nematicides, molluscides, fungicides, herbicides, plant growth regulators, etc.

In a narrow sense, pesticides refer to a class of drugs that are used to kill insects, sterilization, and harmful animals in agricultural production in order to protect and promote the growth of plants and crops.

Because pesticides have a safe isolation period for decomposition.

The safety interval refers to the period from the last application to grazing, harvesting (harvesting), use, and consumption of crops, and the interval required from spraying to the maximum allowable residue reduction. When using drugs in orchards, the interval between the last spraying and harvest must be greater than the safe interval to prevent poisoning of humans and animals.

In order to ensure the quality and safety of agricultural products, it is necessary to pay attention to the safety interval of pesticides in the use of pesticides, that is, the number of days between the last application and the harvest of crops, that is, the date when pesticides are prohibited before harvest.

Only by applying pesticides during the safety interval can we ensure that the amount of pesticide residues does not exceed the standard and ensure the quality and safety of agricultural products. Different pesticides have different safety intervals, and they should be used in accordance with the provisions of the pesticide label.

Usually the pesticide residue attached to the leaves will evaporate in five days to a week, but it is best to soak it in detergent for 10-15 minutes or in water for 30-60 minutes to be on the safe side. Soak with detergent and the pesticide is removed faster.

Because pesticides have a safety interval, some are one week and some are two weeks, so you need not to use them for at least two weeks before picking.

Otherwise, you will be eating pesticides directly. Plants need time to decompose.

Because pesticides are toxic, they will dissipate a little after a few days, or you can soak them in salt water.

Vegetables that have been sprayed with pesticides can be eaten after 5-7 days.

Pesticides attached to vegetables generally remain in about 5-7 days and will slowly evaporate, and can be eaten after the effect is completely volatilized. But it is necessary to draw conclusions according to the specific use of pesticides, if it is a high-efficiency and low-toxicity pesticide, it can be eaten in about 7-10 days of medication, but if it is moderately toxic, it needs to be eaten about 15 days of medication, and if it is sprayed with a higher concentration of pesticides, it needs to wait longer, or even can not be eaten.

Residual pesticides attached to vegetable leaves are best soaked in detergent for 10-15 minutes or in water for 30-60 minutes for safety. However, soaking with detergent will remove pesticides faster. Fruits and vegetables should be rinsed before soaking, that is, the fruit and vegetable surface should be thoroughly cleaned and then soaked in water for 10 minutes, but do not soak for too long to avoid the surface pesticides entering the water and returning to the inside of the fruits and vegetables.

Vegetable washing method

1. Soak in salt water

Generally, rinse with water at least 3 or 6 times, and then put in light salt water.

Soak for 1 hour, then rinse with water 1 time. For the cabbage vegetables, you can cut them first and soak them in water for two hours.

2. Soak in alkaline water

Generally, edible alkali is added to 500 ml of water.

5 grams 10 grams are formulated into lye. Put the fruits and vegetables after the initial rinsing in alkaline water, mix enough alkaline water according to the amount of vegetables, soak for 5 15 minutes, rinse the fruits and vegetables with water, and repeat the washing about 3 times The effect is better.

3. Blanch with boiling water

Generally, the washed fruits and vegetables are placed in boiling water for 2 to 5 minutes, then removed immediately, and then washed with water once or twice, and then placed in a pot to cook into dishes.

<> taking herbicides as an example, if it rains more than 6 hours after spraying, the efficacy of the herbicide will usually not be affected, and if it rains within 6 hours after application, you can observe the growth of weeds for a period of time, and decide whether to respray according to the specific situation. If the pesticide is to be re-sprayed, the dosage of the drug should be appropriately reduced, or other herbicides should be sprayed to avoid pesticide damage and ensure the effect of the application.

1. Is it effective to rain with pesticides?

1. There are many types of pesticides, and the efficacy is also different, taking herbicides as an example, if it rains after 6 hours after spraying, it will generally not affect the efficacy, if it rains within 6 hours, you can first observe the growth of weeds for 1-2 weeks, and decide whether to re-spray according to its growth.

2. If the rainfall is more, reaching the level of moderate rain and above, the water content of the soil in the field at this time is more, and the water absorbed by the plant will also increase, which will cause the drug absorbed by the weeds to be diluted by the water.

3. When there is more water in the plant, the transportation efficiency of the drug in the body will be affected, and in this case, it is generally necessary to re-spray the drug to achieve the weeding effect.

4. If it is necessary to re-spray, the amount of drug used should be reduced, or other herbicides with different effects should be sprayed, which can not only prevent pesticide damage, but also ensure the effect of pesticide application.

Second, the pesticide vegetables can only be eaten after a few days

1. If it is sprayed with low-toxicity pesticides, it can generally be eaten after about 7-10 days. If a toxic pesticide is sprayed, it usually takes about 15 days or more before it can be consumed. If you spray highly toxic pesticides (such as carbofuran, methocarb, methamidophos, etc.), it is recommended not to consume them.

2. If there are pesticide residues on the vegetables, they can be thoroughly cleaned first, and soaked in detergent solution for 10-15 minutes (or soaked in water for half an hour to 1 hour), then removed, and the residual drugs can be effectively removed after re-washing.

3. It is recommended to soak vegetables with detergent solution, which can remove residual drugs faster. It should be noted that the soaking time should not be too long to prevent the drug from entering the water and being re-inhaled by the vegetables.
