How many days does it take to eat cabbage?

It takes at least ten days and half a month for the insects to kill the cabbage before it can be eaten normally.

Because this drug has drug residues, although it is low toxicity, if you eat too much, it will also have an impact on your health and cause food poisoning.

How long can you eat the medicine is mainly related to the medicine, the slightly toxic pesticide can be eaten after 7-10 days, and the medium poison can be eaten after 15 days. Generally, the residual fertilizer attached to the green leaves will evaporate in 5 days to 1 week, but it is best to soak it in detergent for 10-15 minutes or cold water for 30-60 minutes to be safe. It should be noted that the soaking time should not be too long to prevent the surface fertilizer from entering the inside of the vegetable.

1. The vegetables can be eaten for a few days after being sprayed with insect medicine.

1. The insecticide can be eaten for a few days, which is related to the medicine. Generally, slightly toxic pesticides can be eaten after 7-10 days, poisoned pesticides can be eaten after 15 days, and vegetables sprayed with high toxicity and high residue pesticides can not be eaten no matter how long it takes.

2. Under normal circumstances, the residual pesticides on the leaves of green cabbage will volatilize after about 5 days to 1 week, but for safety reasons, they must be soaked in detergent for 10-15 minutes, or soaked in cold water for 30-60 minutes. Generally, leafy vegetables are heavily polluted by pesticides, among which leeks and rape are polluted with the largest proportion, and nightshade vegetables such as green peppers and tomatoes are relatively less polluted.

3. When soaking vegetables, you must pay attention to cleaning before soaking. However, the soaking time should not be too long to prevent the surface fertilizer from entering the inside of the vegetables.

2. Vegetables are suitable for picking in the morning or evening.

1. Vegetables are more suitable for picking at night, because after a day of sunshine in the evening, the nutrients in the body are relatively high, which is the best time for picking. Do not apply raw manure water for 30 days before harvesting, as this can cause large amounts of nitrate and nitrite to be absorbed by vegetable roots or leaves.

2. Before picking, you can spray a little plant growth regulator on the vegetables, because the growth regulator can improve the photosynthesis efficiency of vegetables to a certain extent, so as to achieve the purpose of early maturity, high yield and high quality.

3. Do not spray pesticides before picking vegetables, and choose low-residue types even if you want to spray, so as to avoid pesticides entering the body when eating vegetables.

It takes at least a week or so to do it, and the leaves need to be sprinkled daily.

The ingredients are different and the potency is different.

The main ingredients of chlormonocide are ivermectin, praziquantel, albendazole, synergist, and long-acting sustained-release agent. Chlorothalonil is a new type of high-efficiency fungicide, which can quickly penetrate into the inside of plant branches and leaves, kill pathogenic bacteria that invade crop tissues, and prevent the occurrence and expansion of early lesions, with significant antibacterial and sterilization effects.

After beating trichlorfon, the cabbage can be eaten for about 7 days.

Trichlorfon is suitable for the prevention and control of chewing mouthparts pests on rice, wheat, vegetables, tea trees, mulberry trees, cotton and other crops, as well as domestic animal parasites and sanitary pests.

As an organophosphorus insecticide, it is a high-efficiency, low-residue and broad-spectrum insecticide, which mainly has stomach toxicity effect, and has both contact killing effect and osmotic activity. It has a wide range of applications in agriculture, and is used to control a variety of pests such as cabbage worms, cotton leaf jumping insects, mulberry silkworms, fruit tree leaf bees, and fruit flies.

It's usually about a week.

Different pesticides have different safety periods, one week, half a month, and one month, depending on the instructions, as well as the weather conditions after application.

Three to five days is fine, rinse more.

Different vegetables, different pesticides, and different seasons have different safety intervals. According to the regulations promulgated by the Ministry of Agriculture, the safety interval of several commonly used pesticides in vegetables is.

40% dimethoate emulsion safety interval, Chinese cabbage not less than 10 days, Chinese cabbage not less than 7 days, the basic principle that should be mastered is that the pesticide toxicity is larger, the dosage is more, the concentration is high, and the temperature is low, the safety interval harvest period should be longer; Conversely, it can be shorter. Vegetables should never be picked immediately after application.

For pesticide varieties and vegetable varieties that have not yet been specifically specified, the current general implementation method is: high temperature in summer, pesticide toxicity disappears quickly, the safety interval after pesticide application is 5 7 days, at least 7 10 days in spring and autumn, and more than 15 days in winter.

It's not realistic to leave it for a few days. My solution is to wash the dish and soak it in a basin for 15 minutes, sprinkle in a little salt, and rinse it with water before putting it in the pot.

After a week, it was ready to eat.

If it rains during this period, you can eat it for a week.

<>1. Use of pesticides: 2-3 days after the emergence of Chinese cabbage, spray 1 time of cypermethrin, emamectin benzosalt, chlorantraniliprole suspension, imidacloprid mixture, and spray again every 5 days, requiring no residue and low toxicity to avoid harming cabbage seedlings. 2. Use poison bait:

After the seedlings emerge, sprinkle poison bait made of phoxanthion and chopped fresh vegetables around the vegetable field, and be careful not to sprinkle it on the cabbage seedlings. 3. Clean up the weeds: pull out the surrounding weeds in time, destroy the living place of pests, and reduce the source of insects.

1. How to treat insects with just out of cabbage

1. Use chemicals.

1) Generally, 2-3 days after the emergence of Chinese cabbage, spray cypermethrin, emamectin benzoate, chlorantraniliprole suspension, and imidacloprid mixture, and spray again every 5 days.

2) It should be noted that because the newly emerged Chinese cabbage is relatively tender, it is recommended to use a pesticide with no residue, good insecticidal effect and low toxicity.

2. Use poison bait:

1) When the cabbage emerges, you can mix the phosphine in the chopped fresh vegetables, and then sprinkle the poison bait around the vegetable patch at night.

2) It should be noted that the poisonous bait should not be sprinkled on the cabbage seedlings to avoid pesticide damage.

3. Clean up weeds.

1) Because pests usually hide among the weeds to harm, it is necessary to clean up the surrounding weeds in time to destroy the living environment of pests and reduce the source of insects.

2) Before the cabbage emerges, herbicides can also be used reasonably to kill weeds to avoid pests hiding in weeds.

Second, how many days is the seedling period of Chinese cabbage?

1. Seedling time.

The seedling period of Chinese cabbage is generally about 45 days, but because the varieties of Chinese cabbage are different, the time of the seedling period will also change, so the specific length of the seedling period of Chinese cabbage needs to be determined according to the actual situation.

2. How to manage the seedling stage.

1) After the emergence of Chinese cabbage, it is necessary to strengthen water management to ensure that the soil is moist and make the cabbage grow better. It should be noted that watering should be reasonable according to the actual situation, if the water retention of the vegetable field is better, it can generally be watered once every 2 days, and vice versa.

2) In order to avoid weeds competing with cabbage seedlings for nutrients, it is also necessary to pull out weeds to prevent poor growth of cabbage seedlings.

3) During the growth period of small white seedlings, it is necessary to ensure that there is appropriate light, but if the temperature is too high and the light is too strong, it is necessary to have proper shading, and at the same time, when the temperature is relatively low, it is also necessary to pay attention to heat preservation to ensure that the living environment is suitable.

If there are more baishen jujube insects in cabbage, the following measures can be taken to alleviate it: spray a large amount of clean water: spraying a large amount of clean water can dilute the pesticide concentration on the cabbage leaves, so as to achieve the effect of reducing the damage of pesticides.

Add an appropriate amount of alkaline surface to the sprayed water: because most pesticides are acidic, neutralization reaction will occur when encountering alkaline substances, reducing the efficacy, so it can speed up the decomposition of pesticides and reduce the pesticide damage of crops from the cavity. Please note that if the situation is serious, it is recommended to have a professional in the field for assessment and disposal in a timely manner.
