What pesticides are used to make green leafy vegetables green

Pyraclostrobin is a pesticide that can make the foliage of plants green quickly, and it is better to add iron and magnesium fertilizers and urea.

In fact, in this case, no pesticides are used, and the use of pesticides will pollute the environment, as long as the plant is sprayed with a 1% or 500% ferrous sulfate solution.

Ye Huilu, according to a scientific point of view, does not belong to pesticides, but to fertilizers. The principle is to increase the enzyme activity of plants and enhance photosynthesis. So that the yellow leaves and small leaves of the plant can be quickly adjusted to green.

Answer: Plant spraying foliar fertilizer is a popular way of modern agricultural top dressing, which not only absorbs quickly but also uses less fertilizer, easy fertilization, and can make the foliar green fertilizer 1As one of the three essential elements for crop growth, nitrogen-containing fertilizer has the main role of promoting tree growth, increasing chlorophyll and strengthening vegetative growth. If there is a lack of nitrogen fertilizer, the plant is thin, the leaves are yellow-green, the growth is slow, and the flowering can not be done, such as urea, high-nitrogen liquid fertilizer and other common fertilizers.

2.Iron-containing fertilizer, iron is the one with the most trace element content in crops, and the most abundant in crop roots, followed by lower leaves and stems, and the lowest content in upper leaves and ears. The role of iron in crops is to promote the formation of chlorophyll, and iron deficiency will directly affect the photosynthetic respiration of crops and promote the yellowing of leaves.

3.Magnesium-containing fertilizer, magnesium mainly exists in chlorophyll, phytophyll, and pectin, which plays an important role in photosynthesis, so magnesium deficiency and iron deficiency affect crop photosynthesis and cause the leaves to turn yellow and not green. 4.

Hormone fertilizers, also known as hormones, are foliar sprays that can quickly green crops, but have no significant effect on crop growth or yield. How to make leaves green 1Foliar sprays, can be sprayed.

<> data expansion: you can consider choosing high-efficiency low-DU low-residue shasan pesticides, which must be allowed by the state and can be used on vegetables, such as bromonilaterle, chlorantraniliprole, emamectin salt, acetamiprid, chlorpyramide, pyrethroid pesticides, trifluoropyrimidine, etc., which belong to the characteristics of low xing, microdu, good safety, low crop residues, and protection of beneficial organisms. <>

Pesticides are known to be toxic and harmful to the body. Therefore, we must be cautious to use those with low toxicity and short residual effect, which is extremely important for our own safety! Green worm fungus, borericidal bacillus, caterpillar pine, golden thuringiensis, Beauveria bassiana.

Pyrethrins: pyrethrin, deltamethrin, cypermethrin.

<> suggest that vegetable growers do not use pesticides during the planting period, if it is a large-scale planting of vegetables, it must be used, and it is also recommended that we choose a non-toxic, harmless, and no chemical ingredient pesticides for weeds and insects. The agent acts on the mitochondria of cells in insects, and acts through multifunctional oxidases in insects, mainly inhibiting the conversion of adenosine diphosphate to adenosine triphosphate.

The household does not raise pigs, and the three birds rely on the money from the part-time job to buy it as a plate. In addition, spraying agricultural fertilizer, any crop in modern times, without spraying pesticides, there is no harvest. In the past, it was only a seasonal crop, and there were no pests.

Today's varieties have a lot of insect pests. But I know very well that people are not as good as heaven, natural disasters are inevitable, pests and diseases occur from time to time, and weeds can be seen everywhere. If the manufacturer does not produce chemical fertilizers and pesticides, farmers cannot use chemical fertilizers and pesticides.

For example, if there is no market for 666 powder, farmers will not use this insecticide. If chemical fertilizers and pesticides are harmful to humans and animals, then production and use should be limited.

Do not use pesticides, not because of anything else, or because of small households, the planting area is limited, mainly can be used as waste, save costs, and the second is to eat by yourself, not for sale, do not care about the quality of the product. When all the farmers in China have left the land, the crops, the fruits and vegetables, they will no longer use pesticides and fertilizers. However, professional and technical personnel in the land of medicine fish in China still use pesticides.

It can be sung in a high tone, but agricultural production is something that needs to be paid attention to. Singing a high note with a hungry stomach will never sing well with a high note.

If you don't know how to spray pesticides, you can consult your grandparents, after all, grandparents have farmed.

You can ask your neighbors to help you, or you can ask your relatives or your parents to help you, but you must learn it yourself.

Ask for advice from others, ask from experienced people, and you can learn.

The growth of plants also needs trace elements, the role of agricultural chlorophyll is to help supplement the trace elements of crops, keep the health of fruits and flowers during the growth process, and also be able to strengthen crops, so that the yield can be increased, it must be used in the production of a variety of vegetables and fruits, to such as tomatoes, cabbage, zucchini, watermelon, loofah, strawberries, sweet potatoes, beans, cauliflower, potatoes, pumpkin, apples, bananas, cherries, mulberries, corn, wheat, tobacco, rice, chlorophyll must be used to increase yieldIt can control the prosperity of crops, make individual plants thicker, regulate nutrients, and promote more developed root systems. For example, potatoes in the use of agricultural chlorophyll, the tuber becomes larger, the skin becomes smoother, after the use of more than 20% of the yield can be increased, this crop nutritional supplement elements are cheap, the use of pollution-free, but different kinds of crops use the dosage is not the same, generally the use of sprayers diluted after spraying on the leaves of crops, the above is the role of agricultural chlorophyll, the product can not be mixed with hormones, if the use of alkaline pesticides, should not be rented when accompanied by chlorophyll, Many of the crops seen on the market today use this product.

What is Chlorophyll?

Chlorophyll is a green alkaloid found in green plants, algae, and some bacteria. In plants, chlorophyll is a key substance for photosynthesis, being able to absorb light energy and convert it into energy that plants can use.

Do vegetables contain chlorophyll?

Vegetables generally contain chlorophyll, and green vegetables usually contain more chlorophyll, such as spinach, lettuce, broccoli, green peppers, etc. Not only that, yellow and orange vegetables such as carrots, pumpkin, tomatoes, etc., also contain a certain amount of chlorophyll.

Can vegetables be sprayed with chlorophyll?

Although vegetables already contain a certain amount of chlorophyll, in some cases, chlorophyll spraying may be considered. Some diseases and other factors may affect the normal growth and health of vegetables, and the color of vegetable leaves may be yellowed or whitened, so chlorophyll spraying can be considered.

What are the benefits of chlorophyll spraying?

Spraying chlorophyll can promote the normal growth and health of vegetables, and in the absence of light, it can enhance chlorophyll photosynthesis, improve light use efficiency, and promote plant growth. At the same time, spraying chlorophyll can also improve the stress resistance and disease resistance of vegetables, making vegetables healthier and more nutritious.

How to spray chlorophyll?

Generally, the chlorophyll solution can be sprayed on the surface or leaves of vegetables by solution spraying, and then wait for the leaves to absorb. The concentration of spraying should be determined according to different varieties and different situations, it is not recommended to spray by yourself, try to seek professional help.

Precautions Spraying chlorophyll needs to be noted, too high concentration will cause leaf burning and even death; If the concentration is too low, it will have no effect, and the spraying concentration should be carefully decided according to different growing environments and vegetable varieties. In addition, the spraying time should be selected in the morning or evening to prevent the sun from being too strong and damaging the plants, and the spraying interval should not be too short.

Conclusion In general, vegetables can be sprayed with chlorophyll, but you need to pay attention to the ways and means to avoid unnecessary damage to vegetables. Spraying chlorophyll can make vegetables healthier and more nutritious, which is conducive to the normal growth and development of plants.

Hello, you can use sodium dinitrophenol, sodium dinitrate phenol is a powerful cell activator, after application, it can quickly penetrate into the plant body, promote the protoplasm flow of cells, and improve cell vitality. It can significantly promote the photosynthesis ability of plants, speed up the speed of plant sleepiness and hair roots, and have different promoting effects on reproduction and fruiting. It is widely used in wheat, corn, rice and other food crops, peanuts, soybeans, potatoes and other cash crops, cucumbers, tomatoes, eggplants, peppers, watermelons and other vegetable crops, apples, pears, bananas, kiwifruit, mangoes, longans, lychees, grapes, guava and other fruit trees and a variety of Chinese medicinal materials and flowers.

Due to its high efficiency, low toxicity, no residue, wide range of application, no residue, wide range of concentration, etc., it has been designated by the Food and Agriculture Organization of the International Association (FAO) as a recommended plant growth regulator for green food production.

Real organic food has been very popular in the market, and there are not many real organic green vegetables in the market now. For example, vegetables with organic certificates are not necessarily organic vegetables, and vegetables without organic certificates must not be organic vegetables, even if they are planted cleanly, they cannot be called organic vegetables. So, what are real organic greens?

Are real organic greens pesticides? The following country songs will be with you**.

1. Are vegetables with wormholes organic greens? Can you eat vegetables that have been bitten by insects?

Vegetables with wormholes are not necessarily organic greens. Because those with wormholes are not necessarily those that have not been sprayed with pesticides, and some are pesticides that have been sprayed after the wormholes appear; Pesticides are not necessarily not environmentally friendly, and most pesticides are pesticides with relatively low residues, as long as the safety period has passed, the problem is not big.

It is best not to eat vegetables that have been bitten by insects. Because insects will produce harmful substances in the process of biting vegetables, such as aflatoxins (strong carcinogens), which will induce liver cancer, which is more harmful; Once the vegetables are eaten out of the hole, vegetable farmers will definitely use higher concentrations of pesticides to prevent and control in order to "rescue" the vegetables. It can be said that vegetables with insect eyes are not only unsafe, but may be more dangerous.

2. Real organic green vegetables are not allowed to use chemically synthesized pesticides, but biological, physical and mineral pesticides or methods without any pollution can be used to achieve the purpose of insect treatment and disease prevention. Such as insect nets and insect control, yellow or blue boards to kill insects, etc.

3. Are there many organic green vegetables on the market at present?

It is difficult to market vegetables that are completely free of pesticides.

When I grow vegetables, especially Chinese cabbage, pai cai and Shanghai greens, etc., don't grow too tall without pesticides, and the dense little insects will crawl all over the leaves, and they will all be eaten up in a few days. In this case, how can there be vegetables to market? Some people say that the current organic certification is also very messy, whether it is really organic depends on the conscience of the enterprise, so when you see that kind of high-end vegetables, you will take a detour, which is purely a quick response to people who are stupid and have a lot of money.

The bar for growing truly organic greens is high. In the planting of organic green vegetables, it is necessary to ensure that there is a certain isolation zone between the organic land and the conventional land, including the water quality and agricultural tools of the watering land to avoid pollution, and to achieve that the planting land of the base does not produce for 5 years, and there is no income and net input within 5 years. Every year, the crops should be rotated, and the crops will grow into the ground, and the soil organic matter content will be continuously improved, and during this period, a large amount of organic fertilizer should be applied, and chemical fertilizers, pesticides, insecticides, etc. must not be used.

Think about it, just this requirement, how many people can do it?

Truly organic greens are something that can only be achieved by being tested with a conscience. In the production of organic green vegetables, it is necessary to avoid the transgenic and transgenic derivatives of vegetable seeds, and to use organic seeds, and to use organic fertilizers in the planting process, and to absolutely prohibit the use of pesticides in the planting process. If the real epidemic or insect plague comes, when facing the harvest of the year or season, whether to use medicine or not, this is definitely a test of the conscience of the operator, at this time the capital is profit-seeking, can you pass the test?
