If you want to prevent pests when planting peanuts, what skills should you master when dressing seed

Before planting peanuts, the first thing to do is to make preparations, remove the turf on the planting ground, collect the turf after being exposed to the sun, and then spread soil on top of the turf, light it on fire, and call it "fire ash" in the local dialect. Therefore, underground pests have become a major obstacle to the high and stable yield of peanuts. According to the survey of Xinxiang Plant Protection Station, the main types of underground pests of peanuts are grubs, mole crickets, needleworms, and new black ground bead scales.

At the same time of insecticide, we should pay attention to the prevention and control of diseases, that is, the seed dressing agent must have excellent fungicides, and it is best to add special seed dressing fertilizer.

It is necessary to purchase the most efficient and economical peanut seed dressing from agricultural material stores; Before sowing, farmers should mix seeds evenly, which can effectively prevent and reduce the harm of underground pests and soil-borne diseases to peanut seeds and growth, and effectively increase the stress resistance of peanut plant growth"Low concentration of poison (agent), high efficiency effect". When purchasing, you must go to the entire agricultural material store, so that it is a formal channel, which can well ensure the effectiveness of the seed dressing, which is a foundation. Try to use a special peanut seed dressing machine, and stir carefully to avoid peeling and crushing of peanut seeds.

Seed dressing should be even, so that each peanut seed can be coated. After mixing, find a cool and ventilated place to spread out and dry evenly, and handle it gently during the operation.

<> kinds of peanuts are generally dressed, and imidacloprid, thiamethoxam, clothianidin, dinotefuran and other pests are controlled. At present, there are many peanut fertilizers, such as chlorpyrifos peanut fertilizers of Henan Vision. Peanut has a relatively high demand for geological soil, so it is advisable to choose sandy loam land with relatively flat terrain and strong drainage ability in peanut planting.

Choose the right recipe for the seed dressing. At present, there are a variety of peanut seed dressing on the market, and a formula of high-efficiency and low-cost peanut seed dressing is recommended for growers, which can not only control underground pests but also aphids at the seedling stage, and at the same time prevent dead seedlings and rotten roots. The best principle of seed dressing is "low concentration of poison (agent), high efficiency".

When purchasing, you must go to the entire agricultural material store, so that it is a formal channel, which can well ensure the effectiveness of the seed dressing, which is a foundation.

15 20 kg of peanut seeds per mu need 20 ml of Gaoqiao + 40 grams of Yiwei, first dissolve 20 ml of Gaoqiao + 40 grams of Yiwei with 400 ml of water to prepare the liquid medicine, evenly spray on the surface of peanut seeds, stir while spraying, stir evenly and place it in a cool and dry place, dry it for more than 24 hours before sowing to prevent pests and diseases at the seedling stage.

Try to choose a relatively large container, stir carefully to prevent peanuts from breaking the skin, and stir evenly to prevent peanuts from being stained with medicine.

Peanuts can be used to dress seeds with pesticides, with 48% clothianidin suspension seed coating agent according to the ratio of 250-500 ml 100 kg of seeds dressing, drying and sowing can basically ensure that the seedlings are not destroyed.

The best way to prevent this bug is to spray this pesticide, this pesticide of 670 is very good, spraying twice a day can achieve very good results, about a week of spraying will have a good effect.

Seed dressing with insecticides can kill or repel underground pests, prevent rodents and birds, and promote whole seedlings. To prevent and control peanut seedling diseases, 5 grams of 25% carbendazim per kilogram of seeds are generally used.

Seed dressing with peanut medicine and fungicide can kill all kinds of germs attached to the seeds; Seed dressing with insecticides can kill or drive away underground pests, prevent rodent pests and bird pests, and promote the whole seedling. In order to prevent and control peanut seedling diseases, seed dressing generally uses 5 grams of carbendazim containing 25% per kilogram of seeds; To prevent damage from underground pests, rodents and birds, 2 grams of phosphine 50% octathion per kilogram of seeds should be used when dressing seeds.

Pesticides can be sprayed, which can kill some of the eggs of the bugs, which can kill some pests.

We should put these peanuts in a relatively dry environment, so that we can prevent pests and diseases, and it will also reduce pests and diseases.

Peanut seeds can be coated with seed coating agent, which can play a good role in sterilization and insect control, improve seed vitality, and avoid or reduce the impact of adverse environment. Because at present, the frequent pests and diseases of peanuts remain high, especially in the past two years, the damage of needleworm peanut has become more and more serious. A variety of diseases are intertwined, and soil-borne diseases are serious, which need to be treated from the source seeds.

According to the ratio of 25 grams of rhizobia agent per mu of peanut seeds, put the fungus agent in a clean container, add 2-3 times of water and pour it on the seeds, and then gently stir to make each seed stained with powder to sow seeds. Seed dressing can achieve seed safety, promote germination, is the world's safest seed coating agent, in the peanut growing season can effectively control aphids, thrips, planthopper damage can also prevent and control peanut blight. It can promote crop growth, improve germination rate, and develop root system.

Pharmaceutical seed dressing: The agent of the drug seed dressing can be selected according to the local pests and diseases, and generally can be used with thiophanate-methyl, carbendazim, seed dressing and other agents, and the amount of the agent can be according to the amount of seeds, which can effectively prevent rotten roots and dead seedlings. At present, the seed dressing of phosphine emulsifiable concentrate and dimethoate emulsifiable concentrate can effectively control underground pests; Using kerosene or diesel fuel to dress seeds according to the amount of seeds can effectively prevent underground pests and birds and beasts from damaging seeds and improve the emergence rate.

Good safety: It is safe for seeds, promotes germination, and is the safest seed coating agent in the world.

Good varieties are the key, and the first task before planting is to choose the local varieties that are suitable for planting. In order to ensure the neat emergence of peanut seedlings, it is recommended to treat peanuts before sowing, which can avoid the harm of underground pests and aboveground pests to a certain extent. Sandy soils rich in organic matter are selected for planting, which is soft and conducive to the expansion of peanut fruits, as well as the emergence of peanuts.

Peanut growers must pay special attention to the fact that in mid to late July every year, especially in the peanut kernels planted by people, the most likely to produce underground pests (such as loaches, loaches, etc.). Some agricultural producers say that every year before planting peanut kernels, they need to use worms or poisoned maids to make bibimbap. Generally, after mixing seeds with this type of drug, the peanut kernels will no longer be damaged by underground pests during the growth period.

However, in the rainy season, it is not clear whether peanut growers can find out, that is, whether everyone can use bibimbap, whether the damage of underground pests is still relatively serious when peanut kernels are obtained, or whether many peanut kernels are hollowed out by underground pests.

It is said that peanut seed mixture can prevent underground pests in advance, but only as a preventative effect. In a rainy year, or a year when underground pests occur, this type of bibimbap usually does not work very well.

The damage of peanut kernel was more significant during the planting process. I don't know if you've ever had this experience. When the peanut kernels are perfect, go to the field to pull the peanut kernels, and the peanut kernels are plucked with many small insects and eyes, and some peanuts will be pested after peeling.

Since most of them are caused by loaches, precautions are taken when planting peanut kernels.

In response to loaches, the little helper proposes to closely combine prevention with prevention to prevent problems before they occur, so as to prevent assistance.

Precautionary measures: peanut kernels should be planted without injection to mix seeds, which can very well prevent underground pests (in addition to loaches, other needleworms, ground tigers, loaches, etc. can also be prevented together), and the needle-free ingredients that can be used include full worms, yellow phosphorus, cordyceps, etc.

Precautionary measures: If loaches have already occurred in the farmland, precautionary measures should be taken as soon as possible. The sooner the better, there are three ways to do it:

Poison *** soil layer (bran).

In the case that there are already loaches in the ground, you can use slender soil or wheat husks, pour phosphine or poison grass, mix well and sprinkle them in the peanut kernel field, if it is poisonous soil, you can sprinkle very thin soil, if it is wheat husk, you can sprinkle it around the peanut roots, improve the actual effect of loach prevention.

Irrigation lines

Loaches can also be prevented according to the method of the roots, and the drug phosphine or poisoning can be used to kill the grass, but when spraying the roots, you should pay attention to the concentration value of the insecticide, and you do not have to invest in rainy days.

Nebulizers

If the above two types of methods are inconvenient, you can immediately spray insecticides to prevent loaches, you can apply drugs, you can select new yellow people or full worms, and you can spray many loaches to cause great harm quickly.

You can sprinkle some pesticides around the soil, or stop the reproduction of aphids, or you can prevent insect pests in the soil in advance.

You can sprinkle some pesticide powder in the soil, or loosen the soil frequently, or you can spray pest prevention agents regularly.

You can sprinkle pesticides in water and then water them when fertilizing them, which can also play a good role in removing pests.

After the valley rains, the peanuts are sown. Now seed dressing has become a good method of insect control, disease prevention and yield increase, but many farmers have some misunderstandings about seed dressing, resulting in poor seed dressing effect and even affecting seedling emergence. In the past two days, some farmers have asked whether peanuts can be used to prevent insects with pesticides containing chlorpyrifos.

This pesticide has been used before, but it has been found to be very ineffective. I don't know if I can use this ingredient when planting this year.

Peanut seed dressing is mainly used for insect and disease control, and the general disease prevention drugs are based on the diseases that occurred in the field in previous years, but there are many kinds of pests. For example, grubs, ground tigers, aphids, needleworms, etc. After sowing, it will begin to harm, especially after the peanut pods are poded, the grub is more harmful, affecting the yield and quality of peanuts.

Then, the use of chemical agents to dress seeds is to reduce the harm of underground pests to seeds after sowing, as well as the harm after seedlings emerge. So, in general, there are two important aspects when choosing a drug. The first step is to choose the active ingredient and content.

Second, there must be a certain duration. We often use imidacloprid and chlorpyrifos as seed dressing agents to control pests, and there are also two kinds of compounds. The farmer used chlorpyrifos to mix seeds, which was more effective against grub underground pests.

There are several reasons why farmers say that control is poor:

There are several reasons why farmers say that control is poor:

First of all, chlorpyrifos uses stomach poison to control pests, which is different from imidacloprid insecticidal methods. It has no system characteristics and has a good control effect on underground pests, but it cannot control upper pests such as aphids. When using peanuts to mix seeds, chlorpyrifos microcapsule suspension should be used, but the conventional dosage form has poor effect and short duration of effect.

Then the pesticides purchased by farmers are not standardized, the content is insufficient, or the seed dressing method is incorrect, and the concentration is too high when dressing, which will reduce the control effect and affect the emergence of seedlings. Finally, the choice of chlorpyrifos component peanut seed dressing is influenced by soil conditions. For example, when there is a lot of rain, pesticides will seep into the ground after sowing, and pests will not come into contact with pesticides, thus losing the control effect.

We can see the quality of the seed dressing effect in the growth process of peanuts, and we should avoid misunderstandings when choosing the seed dressing agent. Chlorpyrifos is effective in controlling underground pests. Microencapsulated pesticides have a long effective life, and seed dressing should be carried out the day before sowing.

If you have a large number of aphids or other above-ground pests, you can use agents that contain imidacloprid. Of course, imidacloprid and chlorpyrifos can also be used to dress peanuts. But no matter what kind of medicine is used, it is necessary to choose a regular product and sufficient content.

Some farmers believe that the darker the red color after seed dressing, it proves that the larger the amount and the higher the concentration of the liquid medicine, it is a good medicine. But let's think about it the other way, the color of the seed dressing is a warning color, and its purpose is to distinguish which ones are mixed and which ones are not. It is inedible to avoid accidental eating, it only plays a warning role.

There are many flower diseases and insects, and the yield is low, and there are these misunderstandings that need to be avoided in peanut dressing: 1The darker the color of the seed dressing, the better, the color of the peanut seed dressing is basically red, but not the darker the color, the better, in the case of excessive concentration, it will definitely have an impact on the germination rate of the seeds; 2.

Ignore the ingredients, do not look at the pesticide ingredients, only look at the size of the package, think that the packaging is more cost-effective, must look at the ingredients; 3.Ignoring the content, in fact, the specifications with high content are smaller, but the active ingredient will not be less, and the high content of active ingredients is better than that of pesticides with low content.

These misunderstandings should be avoided, and some peanut dressing can only supplement soil fertilization with micro-fertilizer, and cannot replace fertilization. The active ingredient in the seed dressing is not effective against all pests and diseases. No, the darker the color of the seed dresser, the better.
