What are the reasons why wheat can have insects when stored? How can it be prevented?

The small insects that are stored in wheat are generally called warehousing logistics.

Pest. The losses caused by pests in warehousing and logistics are generally relatively large, and the losses caused by long-term storage of grain due to insects are about 5-10%. Warehousing and logistics pests not only cause immediate ingestion of harmful wheat resulting in quantity loss, but also cause hot mold and endotoxin.

It will not only endanger commercialization and useability, but will also continue to immediately lose the use value of seed use.

It generally refers to the moisture content and relative humidity of wheat.

Because water is an indispensable chemical substance for the growth and development of storage and logistics pests, when the moisture content of wheat is high, or when the relative humidity of the air is very high during storage, it is generally easier to eggify and harm the eggs of storage and logistics insect pests in wheat. For example, wheat moths are usually harmful when the moisture content of wheat is 9-10%. If the moisture content is above 13% and the relative humidity of the air is above 70%, there are often many breeding and daily life hazards.

Before storing the wheat, it is important to keep the moisture content to a minimum.

Generally, when the moisture content of wheat is less than 12%, it is not easy to produce insects and mold, so the wheat will be exposed to the scorching sun. Generally, when the wheat is put into the warehouse for storage, it must be exposed to about 40 degrees Celsius in the hot summer before entering the warehouse, and then we have to carry out a sealing solution, so that you can quickly make the wheat dormant and eliminate insect pests. There are many kinds of insect pests of general wheat, such as large grain thieves, corn elephants also have wheat moths, as long as you do a good job of prevention and control.

It can be used as the high-temperature closed type just said, or it can be fumigated by some medicines. There are many kinds of insect pests of general wheat, such as large grain thieves, corn elephants also have wheat moths, as long as you do a good job in prevention and control, you can use the high temperature closed type that is often said just now, and you can also fumigate through some medicines. Natural ventilation is crucialIn some wet and rainy seasons, the relative humidity of the air is very high, which may be digested and absorbed by the wheat seeds, which will then accelerate photosynthesis.

A lot of the heat is stored in the wheat.

This is due to the relatively high temperature and the environment in which it is used, so try to keep it in a dry place.

This has a certain relationship with humidity, and temperature also has a certain relationship, the temperature is relatively high is prone to this situation, the surrounding environment is directly related, we must pay attention to the cleanliness of the surrounding environment, maintain the appropriate temperature.

It could be too humid, or it could be too hot. At this time, it must be dried in time, and the storage environment must be paid attention to.

How to store the newly harvested wheat so that it does not have insects? Can putting liquor in wheat hoards prevent insects? During the wheat harvest season, when the wheat is harvested, some are sold directly, some are dried and then sold, and some are stored after drying.

Wheat seed coat is thin, the internal tissue is relatively loose, the air permeability is good, it is easy to release water in the sun, keep the wheat dry, but at the same time, in the case of high air humidity, it is easy to absorb water, resulting in an increase in moisture content, mildew and insect pests. Before storage, wheat seeds should be exposed to sunlight and the moisture content should be reduced by less than 12%. The reason is that wheat with a moisture content of less than 12% can be stored for a long time and is less prone to insects and mold.

<>, as an ordinary farmer friend, may not have precise instruments to measure moisture content. Under normal conditions, after the wheat is harvested, the weather becomes clean and it is exposed to the sun for 2-3 hours at noon. Wheat seeds are heat-tolerant, so storing them in the sun at high temperatures helps kill insects and help them get through their dormant period.

Under normal circumstances, the weather is sunny in summer, and the wheat can be dried to about 40 degrees, at this time, it can be stored in time, and then sealed, which takes about 10 and a half days, which can effectively kill pests. In the process of wheat storage, the main pests are moths, such as corn, large grain thieves, grain and so on, after the completion of the control work, you can take high temperature sealing method or agent, after fumigation, after the general practice of wheat drying, do a good job of cleaning (remove impurities), and then hit a levit, immediately sealed, fumigated, the available reagent is aluminum phosphide.

In autumn and winter, the temperature and humidity of the granary should be checked regularly, especially in some rainy and wet seasons. The wheat in the barn is easy to heat. If the temperature rises too quickly, it should be ventilated in time to cool down.

In addition, some family granaries are not very airtight, if there is water ingress, such as rainwater leakage or stagnant water, it will cause wheat mildew, and it is necessary to ventilate in time to ensure the quality of wheat.

Put it in a dry place, put it in a sunny place, put it in a good place, put it in a relatively high place, and put it in a cool place; I think that putting liquor in Maitun can have a preventive effect.

You can store the wheat in a rice jar, or you can put some orange peel appropriately, so that it has the effect of repelling insects and should be placed in a closed environment. In this way, it can also prevent insects, and alcohol has the effect of sterilization and disinfection.

Hello, dear, you put wheat in **.

There are about 80 cubic meters of iron silos in the iron silo.

Wheat is applied several times a year.

Usage and Dosage.

Wheat is generally sprayed three times during the growth process. Before the rejuvenation period, the temperature is not very high, and various pests and diseases occur rarely, so generally there is no need to deal with them. In the rejuvenation and jointing period, that is, in mid to late March every year, the temperature gradually rises, and various pests and diseases begin to occur, at this time it is necessary to pay attention to the occurrence of various diseases.

The second application was in mid-April, in order to prevent and control scab in time. The third spraying is to prevent the occurrence of premature senescence and dry hot air in wheat, and is generally carried out at the heading stage. The pesticides played in different periods are also different, and pesticides should be reasonably selected for spraying according to the actual situation and the law of medication.

The spraying must be in moderation, otherwise it will also affect the yield of wheat.

1.Rejuvenation jointing stage: sheath withering, stripe rust, total erosion, wheat spider, wheat aphid, with benzoconazole and hexaconazole + bifenthrin + thiamethoxam spray control.

2. Pumping and flowering stage: stripe rust, powdery mildew, leaf wilt, scab, wheat spider, wheat aphid, with benzoconazole or hexaconazole. Copper + thiamethoxam, cyhalothrin, potassium dibasic phosphate.

3 Filling stage: aphids, powdery mildew, leaf blight, armyworms, rust, with benzpropiconazole or hexaconazole thiamethoxam. Copper, bifenthrin, potassium dihydrogen phosphate.

Store wheat. 1. The moisture should be low, and the moisture will be mildew. The safe moisture in the north and south of our country is 13%, as long as the wheat is dried to normal moisture.

The teeth are clenched neatly and disconnected, and it takes a little effort to reach it. And pay attention to the warehouse utensils do not leak and do not return to moisture. Prevent condensation due to large temperature changes.

2. To prevent and control insects, wheat is easy to be attacked by stored grain pests, to avoid insect source infection, for storage utensils to be cleaned, you can take the method of hot storage to kill insects. Aluminum phosphide can also be used to prevent insects and insects as required. 3. The temperature is as low as possible, when the temperature is lower than 15 degrees, all wheat pests can not reproduce, and it is inactive below 10 degrees.

Household storage should avoid direct sunlight as much as possible, and the factory warehouse should meet the basic requirements of thermal insulation. Generally, moldy wheat must be higher than 30 degrees (local temperature) 4, check the grain condition frequently. For the wheat stored in the factory, the temperature, moisture and pests should be measured.

If it is found that the temperature and moisture change greatly, it should be ventilated and dried, and the insects should be prevented and controlled as soon as possible.

Proportion and method of application of stored wheat.

Stored wheat can not be put medicated.

Generally, as long as the wheat grains are not damp, there will be no insects.

If you store it for a long time, and if you don't put it for a long time, don't you put medicine?

Our family also stored wheat this year, and we put it in a bag, and we didn't put any medicine.

What kind of medicine do you put every year?

1. Oxygen-free preservation method: first spread out the wheat to be stored in a ventilated place to dry (note that it should not be exposed to the sun) to dry thoroughly, and then put the wheat into a non-toxic (food) plastic bag with less air permeability (it should be full), tie the bag tightly, and put it in a cool and dry place, so that the wheat can be stored for a long time.

2. Zanthoxylum pepper insect prevention preservation method: Zanthoxylum pepper is a natural antioxidant with a special fragrance and insect repellent effect. The specific method is to put 20 to 30 peppercorns in the pot, add an appropriate amount of water (it is advisable to soak the rice pocket), put it on the stove fire to cook the fragrance of peppercorns, and then remove the pot from the fire, put the wheat bag into the pepper water, take it out to dry after being wet, and then pour the wheat into the pocket.

In addition, wrap a few small packets of peppercorns with gauze, place them on the top, middle and bottom of the rice bag, tie the bag tightly, and put the wheat bag in a cool and ventilated place to prevent wheat insects.

3. Moisture absorption and preservation method of plant ash: at the bottom of the tank containing rice, spread a layer of plant ash (it is best to put the plant ash in a gauze bag and put it at the bottom of the tank), and then pour in the wheat that has been dried and blown through, and the wheat cylinder cover is tight, placed in a cool, dry and ventilated place, which can be stored for a long time.

4. Kelp insect-proof preservation method: Dried kelp has a strong ability to absorb moisture and has the effect of killing insects and inhibiting mold. When preserving wheat, wheat and kelp are mixed in a ratio of 100 to 1, and the kelp is taken out for about 10 days to dry and dry, and then put back into the rice, so that after repeating several times, wheat mildew and insects can be prevented.

1. Zanthoxylum pepper is insect proof. Sichuan pepper is a natural antioxidant with a special fragrance and insect repellent effect. The specific method is to wrap a few small packets of peppercorns with clean gauze and place them on the top, middle and bottom of the jar where the wheat is stored, so as to prevent wheat insects.

2. Neem leaves are insect proof. The neem leaves are half dried, and a layer of neem leaves is placed on the top, middle and bottom when storing grain, and the cover is tightened as the standard, a total of 3 layers. Neem leaves and fruits can also be crushed and sprinkled in the grain pile according to grain layers, and the last layer should be sprinkled more appropriately.

3. Wormwood is insect proof. There are many kinds of wormwood, and as long as they smell, they can be used to repel insects. Take fresh wormwood, wash and dry, put wormwood in a container for storing wheat, and lay three layers on the top, middle and bottom respectively, which can achieve the effect of repelling insects and killing insects.

In fact, not only wormwood, but also Chinese herbal medicines with insecticidal and insect repellent effects can replace wormwood to prevent insects, such as litsea cubeba, camphor leaves, pyrethrum, calamus, etc.

4. Biogas insect control and insect control. A plastic tube is inserted into the bottom of the grain storage container, biogas is introduced into the grain tank, and the grain tank is sealed. Generally, biogas is injected, and the pests in the stored grain are all annihilated after 3 5 days, and this method is used for wheat 5 and toon leaves to prevent insects.

Put a layer of toon leaves at the bottom of the grain storage tank, and then lay a layer of toon leaves every 30cm or so, and then cover a layer of hail on top after filling it with wheat to prevent insects. You can also mix the dried and crushed fragrant leaves into grain and bran finches, which account for grain or feed, and also have the effect of preventing insects, and the effect of frequent replacement of leaves is better.

If you want to prevent wheat insects, you can put garlic and pepper and other antioxidant items in the wheat, and then store them in a cool and dark environment, orange peel contains a special aroma, which can also achieve the effect of repelling insects, or put lime powder at the bottom of the box, spread a plastic bag to block it, and then put the wheat on it, which can also effectively avoid wheat insects.

1. Garlic preservation

If you want to store wheat without insects, you can put it in a container, and then put pepper and garlic in the tea bag, and put it in the center of the wheat, garlic and pepper have high antioxidant capacity to ensure that the wheat is not insect-free.

2. Orange peel preservation

Take an appropriate amount of orange peel and grapefruit peel, put it in the sun to the sun, dry it and put it in wheat, the orange peel contains a special aroma, has a good insect repellent effect, and the orange peel is replaced every other week.

3. Quicklime preservation

Quicklime can also be bent to effectively avoid wheat insects, take an appropriate amount of quicklime and place it in the lowest layer of the box or container, cover it with a plastic bag, and finally put it on top of the wheat to avoid wheat insects.
