What are the commonly used fungicides for fruit trees?

Mancozeb, difenoconazole, azoxystrobin, iprodione, thiophanate-methyl and other fungicides are more commonly used fungicides, which are usually suitable for fruit trees and can make fruit trees healthier.

Zinc Dyszeb, Antibacterium, Streptomycin, Fenthalin, Benlaite, etc., these fungicides are suitable for fruit trees.

Fruit trees are used for many antibacterial. For example, in the early stage of garden clearing, Bordeaux liquid and stone sulfur mixture can be used, and difenoconazole, propiconazole, mancozeb, manganese zinc, etc. can be used in the later stage.

Use new pesticides with low toxicity, high efficiency, low residue or no residue. For example, the drugs that kill red and white spiders with avermectin as the main ingredient include abadenine emulsifiable concentrate, oleotine emulsifiable concentrate, afordine emulsifiable concentrate, and insecticide emulsifiable concentrate. The urea insecticides used to control lepidopteran pests such as leaf miner moths are:

20% pyrethuron, 20% flubolylurea, 25% chlorpyramide No. 3, etc. The prevention and control of apple ring disease, anthracnose and dry rot are: 30% apple rot and 35% strong Kangmycelin water.

Use some new pesticides with a long residual effect. For example, the use of 10% imidacloprid powder to control yellow aphid, compared with conventional pesticides, the residual effect period can be increased by 2 3 times.

Use some low-toxicity organic synthetic insecticides to control peach heartworm. Such as 40% chlorpyrifos EC, 25% egg worm emulsifiable oil, 20% fruit insect buster emulsifiable concentrate, and 25% peach small primary net emulsifiable concentrate.

Some compound fungicides are used to replace pesticides that have developed resistance and single control objects. Such as 50% Shengcheng fruit disease powdericide, 70% round fall net (wettable ultrafine powder, % bacteria must be cured, 50% multi-bactericidal wettable powder and other composite fungicides.

Amino acid micro-fertilizer is easier to absorb than conventional methods, has a fast effect, and has a high rate. For example, ammonia calcium treasure, rich iron No. 1, and zinc-rich No. 1 are respectively bitter pox, yellow leaf disease, and small leaf disease.

The use of domestic drugs as much as possible can reduce costs under the premise of the same prevention and treatment effect. For example, 40% chlorpyrifos emulsifiable concentrate is used for the prevention and control of peach small and cotton aphids, and polyantimycin powder is used for the prevention and control of spotted defoliation.

The application of new pesticide dosage forms is relatively lagging behind. Among the existing dosage forms in China, the old dosage forms such as emulsifiable concentrate, wettable powder and powder account for 75% of the total number of preparations, and some new dosage forms such as microcapsulate release agents, fog agents, ultra-low volume sprays, electrostatic sprays and other high-efficiency and energy-saving preparations have not been introduced or popularized in China.

In real life, in the planting process of fruit trees, in order to ensure better growth, some fungicides are often used, so what are the functions of these things? In fact, their role is very obvious, that is, to help us kill the bacteria in our fruit trees, so as to be more conducive to the growth of our fruit trees. Because of this, they are very important, so naturally we have a great demand for him, and the best result is that there are all kinds of similar products on the market, and our choice becomes very difficult.

So for us, how can we make the right choice to be more conducive to their normal results? Let's take a brief look at it first. <>

The first is to choose a regular brand. For us, although there are many such things, they also have brands, and some big brands have relatively mature products, so they are naturally guaranteed. When we use it, it can also bring us more effects.

This is very beneficial to us, so we must pay attention to the choice of this brand, after all, it directly affects our final use effect. <>

Second, prescribe the right medicine. There are many such products on the market, and the effect of each product is different, and for us, the effect that may be achieved is different. So in order to reduce the impact of this, we have to choose products that are really suitable for us, so that we can maximize its impact and be able to make them more helpful to us.

I hope you will pay attention to it, because these things are really important to us. Only if we can make the right choice, can we reduce his influence and avoid some necessary surprises. Therefore, we must be serious, so that we can better solve the impact of this aspect and avoid his loss, so we must be cautious about this problem.

It can kill germs, effectively improve the yield of fruit trees, prevent pests and diseases, inactivate many enzymes, and promote wound healing.

The effect is that it can destroy bacteria, prevent bacterial breeding, can help fruit trees grow better, can prevent the appearance of some bacteria, and can also have the effect of repelling insects.

It can play a good bactericidal effect, and at the same time, it can also remove insect pests, promote the rapid growth and development of fruits, increase yields, and ensure the health of fruits and vegetables.

There is no doubt that for fruit farmers, a strong and effective fungicide is very important, which can protect our fruit trees from damage, and can also effectively kill pests, so that our fruit farmers can get the maximum benefit, so which fungicides are needed to protect fruit trees well, generally speaking, there are protective agents, it is the most commonly used by our fruit farmers, and the protective agent can effectively enter the inside of the fruit treeTo prevent pests and diseases, kill germs, especially heartworms and caterpillars, generally the protective agents we use can be durable, so that they can last a long time. The second is the eradicator, which kills the residual pests on the surface of the plant, and after the disease of the fruit tree, we can apply or spray on the surface, which can effectively kill the pests in the bark and inner diameter. There is also antibiotics, which is a powerful drug to kill pests, for the leaves of fruit trees, leaf necks have a good penetration effect, especially for mosquito bites, of course, they can not be used when the fruit trees are about to mature, to prevent harm to human body safety.

First, the protective agent, the protective agent in the use of the fruit tree to see whether the fruit tree grows to a certain extent, the use of too early and too early will affect the growth of the fruit tree, generally just when the fruit is used, the protection time is long-lasting, until the fruit harvest will play a certain role.

Second, the eradicator, eradicate some weeds around the fruit tree, prevent the weeds from absorbing the nutrients of the fruit tree, can well protect the growth of the fruit tree to absorb the nutrients in the soil, can be used to plant the fruit tree tools and in the soil, but it is not harmful to the beneficial insects, so that it can not only kill harmful bacteria, but also protect the beneficial insects of our nature, why not.

Third, antibiotics, antibiotics have the effect of inhibiting the growth of fruit trees, and have a good effect on bees and parasites. But it's better if we mix them up so they work better.

For example, there are chlorothalonil, sulfur mixture, eradicator, protective agent, systemic fungicide, antibiotic fungicide and so on. Distinguish according to different functions and effects.

Generally, it is divided into eradication type, sterilization type, systemic type, antibiotic pesticides, or metabolites of fungi, etc., which are included in the fungicidal pesticides.

The more common ones are protectants, and then they also include output agents, as well as systemic fungicides, and antibiotic fungicides. At the same time, it is also necessary to choose the right fungicide according to the fruit tree.

Fruit trees are generally treated with an inazazole fungicide, which is effective against many fungal diseases that attack fruits, vegetables and ornamental plants. Spray maceration of citrus, bananas and other fruits can prevent fruit rot after harvest.

Fungicides, also known as biocides, bactericides and algaecides, microbial agents, etc., usually refer to chemical agents that can effectively control or kill microorganisms in the water system - bacteria, fungi and algae. Internationally, it is usually used as a general term for the prevention and treatment of various pathogenic microorganisms.

Plant surface application method The application of pesticides to the surface of plants is called plant surface application.

Seedlings are treated with pesticides to treat seeds, seedlings, scions, cuttings and other propagating materials to eliminate the germs attached to the surface or inside of these materials, and to ensure that the sowing materials do not bring dangerous diseases.

First of all, we should pay attention to the problem of proportion, and we should also pay attention to the problem of dosage when spraying, and we should avoid rainy or windy weather.

The most common way to use fruit tree fungicides is to use a watering can, wear gloves, spray on the plants, and choose to use it in windless weather.
