What are the control methods of wheat red spider?

The first thing to do is to clean up the surrounding weeds, as these weeds may be infested with a large number of spider mites or some eggs. Some people do not eradicate or treat the surrounding weeds when preventing spider mites, and it is very likely that after we prevent spider mites in wheat, red spiders will appear again in a few days. If we do not find the root cause, it will not do much to treat the symptoms.

Generally speaking, the damage of red spider is that there are some weeds, red spider insects, and some insect eggs, which will cause damage to the wheat in the field after hatching. <>

We also need to understand one of the habits of spider mites, some spiders generally ovulate on this clod of soil, we can choose to use ploughing to bury these eggs in the soil and crush them. This method should often be used before winter, because the hatching of insects often begins to be active in the spring period, and turning the soil in winter can effectively crush a lot of red spiders, so as to effectively avoid the flood of red spiders. <>

Of course, some pesticides can also be used for spraying control. There are many pesticides to kill red spiders, for example, this avermectin can effectively kill red spiders, we can spray these eggs, we can also spray these red spiders. It's just that pesticide spraying once can't fully meet the standard, and the second or third strengthening is needed to effectively kill red spiders.

It is also better to kill red spiders in spring, because red spiders are clustered, and spraying with pesticides when they gather can often achieve twice the result with half the effort. The gathering is generally in the morning, and there are three or four o'clock in the afternoon, and a gathering will be formed during this time period, so when we spray pesticides, we can choose to spray pesticides at 3:00 p.m. 4:4

00 This time period, for some of the people who have gathered, it is good to spray them directly.

You can use watering, so that you can prevent red spiders, and red spiders will not continue to stay here if you water, and you can also use pesticides to choose pesticides that can eliminate red spiders, and then spray, so that you can prevent red spiders, and you can also use fertilizers, and you can effectively eliminate red spiders by choosing the right fertilizer, these methods are all possible, and you can choose a suitable method to carry out.

The method of prevention and control is to fertilize the land when planting wheat, to disinfect the seeds of wheat, to disinfect the soil, to dress the wheat seeds, and to sprinkle some pesticides when planting, so as to prevent wheat spider mites.

It can be controlled with pesticides, or by using agricultural methods, or by using chemical control methods, and can be irrigated, or the situation can be observed in advance, and some pesticides can also be sprayed in advance.

To water in time, and must ensure the fertility of the soil, you can also choose chemical control methods, such as pesticides, be sure to pay attention to the appropriate concentration.

It is necessary to prevent and control pests and diseases in advance, turn the soil in time, choose the right varieties for planting, pay attention to ventilation, and also pay attention to the density of planting.

As follows:

1. It can be controlled with acetamiprid, pymetrozine, avermectin, etc.

2. Imidacloprid, acetamiprid, avermectin, pyridafen, etc. can be used for prevention and control.

3. It can be controlled with imidacloprid, pymetrozine, mite-sweeping and other agents.

4. Wheat red spider aphids can be controlled with avermectin, pyridoxalin, pyridoxrid, etc.

5. Wheat aphids and red spiders can be controlled with pesticides such as acetamiprid and pymetrozine.

6. Wheat aphids, red spiders are controlled with acetamids, pymetrozine, etc.

Precautions for daily prevention and control

1. In daily management, it is necessary to remove weeds in the field and in time, which may become the habitat and wintering place of red spiders.

2. The drier the disease, the higher the probability of the occurrence of wheat red spiders, so watering and other measures can be combined to limit the occurrence of wheat red spiders.

3. Pay attention to the time of medication, the most suitable survival temperature for wheat spider spider is 10-20 degrees Celsius, so when the temperature is particularly high at noon, spider mites may hide, it is recommended to take medicine before 10 o'clock in the morning and after 3 o'clock in the afternoon.

4. Spraying in early spring during the rejuvenation period, regardless of whether there is a red spider in the wheat field, it must be prevented, because returning straw to the field will indeed increase its probability of occurrence. Don't wait until the outbreak of red spiders to use drugs, which increases the cost at this time, and the effect is not necessarily ideal.

Wheat spider spider is a very harmful insect to crops, often distributed in Shandong, Shanxi, Jiangsu, Anhui, Henan, Sichuan, Shaanxi and other places. Wheat, barley, peas, alfalfa, weeds, etc. are infringed once the plant is dwarf, stunted, and the heavy ones dry up and die, the wheat red spider is grown, and the nymphs suck the wheat seedling sap, and the damaged wheat leaves appear yellow-white dots, and the damaged wheat leaves turn yellow later, and the dwarf leaves of the plants are yellow, and the plant grows poorly, can not be tasseled normally, and even dry up and die. <>

Control methods: spray a new high-lipid film 600 times a night to form a layer of physical polymer film before the disease pest, which has the functions of heat preservation, moisturizing, slow release, inhibition of virus spread and insect repellent on the surface of wheat. In the early stage of finding pests and diseases, timely use of highly targeted pesticides after 10 o'clock in the morning and before 4 o'clock in the afternoon when the temperature is relatively high.

In order to promote the growth of wheat and improve the yield, Zhuang Suiling and new high fat membrane can also be added to each mu of the liquid medicine to achieve the purpose of insect control and increase yield. Therefore, rainfall has an inhibitory effect on them, and combined with irrigation and shaking, some wheat red spiders can be drowned. In addition, removing weeds from the edge of the field, especially grasses, can reduce the source of insects.

Wheat red spider can choose 15% pyridoxenone EC 2000-3000 times (20% sweep mite net wettable powder, 3000-4000 times solution), or avermectin (insect mite gram) 5000-6000 times solution, 5% emamectin salt soluble granules 3-4 grams per mu, or use alkyne mites (gmite), benzene mites (dipper), dimethyl ether (mite). If you want to treat other pests as well, you can also use cyflumethrin, chlorpyrifos, fipronide (carfrenon) and other agents. <>

The control of wheat spider spider is actually relatively easy, as long as the right pesticide spraying is done. Our commonly used wheat control agents are: insect mite, pyridoxalin, avermectin, thiobenone, meticar, etc., which can be applied in combination with the pesticide preparations available in local agricultural stores and the resistance of insect pests.

Pesticides should be sprayed regularly, excellent varieties should be selected for planting, watered in a timely manner, and weeds should be removed regularly. Dimethoate powder, Luhebao Maiba emulsifiable concentrate, avermectin, phosphine emulsion, pyridoxalin, these agents are very effective.

It can be controlled by some insecticides. The more effective drugs are, insecticides, insect repellents, pesticides, fertilizers, and herbicides.

At this time, you should choose the right agent, and you should also pay attention to the appropriate use time when preventing and controlling, and you should also pay attention to the protection of the roots, and do not harm the soil.

In recent years, with the drought and lack of rain in winter, the temperature is high, and the phenomenon of "warm winter" continues to appear, and the overwintering base of wheat red spider has increased year by year, coupled with the small body of red spider spider, which is easy to be ignored, and gradually rises from a minor pest to a major pest, which has a great impact on wheat yield. Prevention and control methods:

1. Agricultural prevention and control Fine land preparation. Cultivating in early spring can kill a large number of insects; Shallow tillage and stubble removal after wheat harvest, early deep ploughing after autumn harvest, and crop rotation and stubble rotation according to local conditions can effectively eliminate summer eggs and adults and reduce the source of insects.

Strengthen field management. First, it is necessary to apply foot fertilizer to ensure that the seedlings are strong and strong, and to increase the amount of phosphorus and potassium fertilizer, and at the same time spray a new high-fat film to ensure that the later stage is not defertilized and enhance the crop's own ability to resist diseases and pests. Second, irrigation and weeding should be carried out in a timely manner.

Third, it is necessary to spray Zhuangsuiling at the booting stage to strengthen the physiological function of crops and improve the quality of pollination and filling. Practice has proved that wheat red spiders are difficult to occur in wheat fields where there is no drought in the field, few weeds, and good wheat growth.

Irrigation to kill insects. Irrigation during the incubation period of the spider mites can cause the worms to die by sticking to the surface of the ground by muddy water. Before irrigation, sweep the wheat plants to make the red spider fake dead and fall to the ground, and then release the water, which has a better effect.

2. Chemical control should strengthen the investigation of insect conditions, and pay attention to not turning over the wheat seedlings that need to be observed during the inspection, so as to prevent the insects from falling from being frightened. When most of the leaves are densely covered with white spots, targeted agents and new high-lipid films can be sprayed for prevention and control.

In daily life, it is common for wheat spiders to appear, but if you want to control it, how can you do it? Did you know?

In daily life, there are many farmers who often have red spiders when planting wheat, some of which are very serious, and some of which are not serious, but in daily life, the most serious thing I have ever seen is that those red spiders will make the wheat die directly, so do you know what to do to prevent this phenomenon?

If we want to prevent and control this phenomenon, then we must choose the soil is more fertile and wide land when planting, and we must use farmhouse fertilizer when fertilizing, do not use the fertilizer that buys Qingzheng outside, and often water the plants more, to prevent the occurrence of pests and diseases, if there is a situation of small insects, then we must spray the powder in time, but if the situation of red spiders is very serious, then you can spray some pesticides, So I think if we can do these things well, we will be able to control spider mites, and the effect will be very good.

In daily life, if there are often red spiders in wheat, it will affect the growth of wheat, and it will also affect the quality of wheat, if the situation is very serious, it will also make the wheat die directly, so I think if you can do the above aspects, you will be able to make the wheat grow very well, and the quality of the wheat will become better, and even the yield of wheat will become very large, but I think this is a very normal phenomenon, because those control methods are indeed very good, So these warn some people that if they want to grow wheat well, they must do a good job in those aspects, and never bring unnecessary trouble to themselves.

In ordinary life, if you want to prevent the appearance of red spiders, I think you can often spray some pesticides on wheat, but when spraying pesticides, you must have a small amount, never overdose, because if you spray too much, it will affect the growth of wheat, so you must pay attention to this problem.

Choose wheat varieties that are resistant to diseases and insects, and then control the soil temperature not to be too high, water more, increase the light time, and then spray with pesticides.

It is necessary to spray some pesticides in the wheat when planting, or Fu Jing should be exposed to the sun more when the hall is bent, and the planting distance between the stuffy ones should be increased when planting.

You should choose the drug of the red spider, and you should pre-prevent the mountain stove in advance when you tease the spike, and you must increase the dose of the drug, so that you can completely clean up the red spider.

Find an area where spider mites are infested, so that it can have a ** effect. Spider mites are a pest that likes to congregate, and they usually have a colony, where they often ovulate and then run to the wheat to wreak havoc, so we need to find out where they ovulate. Once we have found the location of ovulation, we can use pesticides to control it, or we can bury it deep in the soil to crush the eggs of those spider mites that have not hatched.

For some weeds on the edge of the field, it is easy to become the habitat of red spiders, so we should focus on removing these weeds, you can spray with glyphosate to kill weeds, and then we can burn these weeds with fire, for red spiders if they ovulate in the weeds, or ovulate under the weeds, these eggs can be killed well by fire. Weeds store a lot of insects, and if you burn the weeds, you will also burn some of the insects to death. <>

Prevention in advance, generally speaking, when the eggs are not adults, they should be killed, for example, deep ploughing can be carried out, and some eggs can be buried, which can effectively reduce the source of insects. You can also do some crop rotation, for example, this year we plant wheat, and in the second year we should plant some peanuts, potatoes, etc., which can effectively reduce the insect pest of red spiders. <>

Use chemical pesticides for effective control. This is a commonly used method and one that many wheat growers often use. After all, there are many pesticides that are sprayed with pesticides to save time and effort to deal with red spiders, and as long as they are blended well, then they can be sprayed on a large scale.

There are many pesticides for killing spider mites, such as this avermectin is a good drug to kill spider mite, and avermectin is a long-acting drug, which can be effectively prevented with one use.
