How to prevent insects in stored grain? Methods for storing food at home to prevent insects

1.Spread two layers of clean paper on the rice surface, put the paper close to the four walls of the container, mix the dry plant ash, chaff ash and lime in an appropriate amount and pile it on the paper, and then cover and close it. This method can make the rice stored for more than half a year without deterioration and insects.

2.Pressing a 2-inch tobacco stem on the top of the rice can keep the rice insect-free for half a year.

3.If moth pests are found, mosquito coils can be lit and smoked. First of all, the grain surface is flattened, 2 3 large bowls are placed per square meter of area, after the mosquito coil is lit, put it into the large bowl together with the incense holder, and the doors and windows are closed and sealed for three days and three nights, and the moth extermination rate can reach 100%.

Non-toxic mosquito coils should be used.

4.Put some liquor in a large bottle, tie the mouth of the bottle tightly with gauze, put it at the bottom of a clean grain storage container, put the dried rice in it, and seal it to prevent insects.

5.Dry kelp and rice are mixed in grain storage containers at a ratio of 1 100, and the kelp is taken out to dry and then put into the grain storage container after one week, which can reduce the moisture content of rice by 3%, make the mortality rate of powder mites and moths reach more than 90%, and reduce all kinds of molds by 60% to 90%. Kelp can be reused after being taken out and dried, and it does not affect the edible value.

6.Wrap pepper and fennel in gauze and put them on the surface of rice, and use 75 100 grams of pepper or fennel per 100 catties of rice.

7.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.

8.Toon leaves are insect proof.

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 the top with a layer of wheat to prevent insects. It can also be mixed with dried and crushed fragrant leaves into grain and bran, which accounts for grain or feed, and also has the effect of preventing insects, and the effect of frequent replacement of leaves is better.

9.In view of the habit of pests who like to climb on the grain surface when mating and laying eggs, they are culled with bamboo brooms, which has a good control effect on moth pests such as wheat moths.

1. Grain storage tools should be clean and tight. It is best to put the grain in jars, jars, buckets, and have a tight lid. If you use a cloth bag, put a plastic bag on the outside of the bag and tie the bag tightly.

2. Soak the cloth bag in boiled pepper water, then put the grain in the bag after drying, and then wrap some new pepper in gauze, put it on the top, middle and bottom of the grain respectively, and tie the bag tightly. This not only prevents mildew, but also repells insects.

3. Mix kelp and rice in a ratio of 1:100 by weight, and take out the kelp every week to remove moisture, which can keep the rice dry and not mildew, and can also kill rice worms.

4. Put a few crab shells, turtle shells or shallots in the storage box, or sprinkle 1 inch thick plant ash, spread white paper or gauze, seal the container, and place it in a dry and cool place, which can also achieve the purpose of preventing insect moth.

Wrap some peppercorns in gauze and put them in a container where the grain is stored.

1.Insecticidal phosphorus: Insecticidal phosphorus is the main agent used in rural areas to control stored grain pests.

It is a highly effective, low-toxicity, low-residue insecticide. The insecticidal phosphorus has a long effect, and it is very effective in controlling corn elephants, sawsaw grain thieves, long-horned flat grain thieves, wheat moths and other stored grain pests. Insecticidal phosphorus is a high-purity malathion used to mix grain, pay attention to the mixing should be uniform, and it is best to mix the medicine before the grain enters the warehouse on the drying field.

It can be sprayed evenly on the grain with a 20ppm insecticide phosphorus solution. The moisture content of the grain should be within the safe moisture standard, that is, the water content should be less than 13%. It is forbidden to mix insecticide phosphorus and dichlorvos, otherwise it will have a toxic effect.

There should be a safety interval of four months after application before it can be processed and consumed.

2.Grain Preservation Phosphorus: Grain Preservation Phosphorus is a grain protection agent developed by the Chengdu Grain Storage Science Research Institute of the State Food Administration, which has a good control effect on grain storage pests, and is especially suitable for rural grain storage.

The ratio of phosphorus dosage to raw grain is 1:2500. That is, each bag of 100 grams of grain retention phosphorus can be mixed with 250 kg of raw grain.

When using grain-preserving phosphorus, the grain must be dry (in line with the safe moisture standard). And the grain is insect-free or basically insect-free.

3.Phosphine.

Phos is a grain protective agent preferred internationally, its chemical name is methylpyrimidine (sulfur) phosphorus, and the common dose for the control of stored grain pests is generally 5ppm.

4.Grain worm (grain protectant).

Guworm net is a compound plant-based insecticide mixed with 4 6 kinds of Chinese herbal medicines as the main raw material and a small amount of chemical agents. It has a strong effect on repelling, avoiding and touching pests. It has an aromatic smell of Chinese herbal medicine.

The insecticidal effect is remarkable. The ratio of the net dosage of cereals to raw grain is 1:2500, that is, each bag of 200 grams of powder can mix 400-500 kg of raw grain.

5.Aluminium phosphide (fumigant).

Farmers commonly use aluminum phosphide tablets for grain storage, about 3 grams per tablet. The dosage is generally calculated as 1-2 tablets (3-6 grams) per cubic meter. Generally, 5 tablets per ton (1000 kg) of grain.

When applying the medicine, the tablets are first packed into a small cloth bag (one piece per bag), the cloth bag is tied tightly with a rope, evenly buried in the grain pile, so that the phosphine is released slowly, and the grain is sealed immediately after application (pay special attention to the sealing around the bottom) to ensure the effect. After fumigation for 5-6 days, ventilation should be carried out for 3-5 days, and the cloth bag should be taken out, and the water source should be far away, and a pit should be dug and buried deep in the soil.

The above agents are only used for storage in raw grains and seed warehouses, and should not be used for finished flour and rice.

1. Prepare simple peppercorns, garlic, dried ginger, fennel, star anise, etc., and then choose one or several, then wrap it in gauze and put it in the grain. Generally, it is more appropriate to put 50 grams of spices in 25 kilograms of grain.

2. When using jars, jars and other containers to fill grain, they can be sealed with plastic film, and tied tightly with ropes to suffocate pests to death.

3. Mix fresh and dew-free poplar leaves or sleeve leaves in the grain for storage, which can play an insecticidal role.

4. Dry and crush the leaves of Kudong trees and wild chrysanthemums, wrap them in cloth and tie them tightly, and put them on the surface of the grain or bury them in the grain, which can not only prevent insects, but also keep the grain in normal color and smell.

5. Spread paper on the surface of the grain, and then mix the plant ash, bran ash, lime and coal ash on the paper, which can prevent insects and moisture, so that the grain can be stored for half a year without deterioration and insects.

The methods of storing grain at home to prevent insects include ventilation management, the use of pepper to prevent insects, garlic to prevent insects, and plant ash to prevent insects.

1. Do a good job in ventilation management, in the storage environment of high temperature and high humidity, it is easy to cause insect pests, therefore, regularly ventilate the storage space, especially when there is even rainy weather, not only insect pests are easy to appear, but also easy to mold, in order to ensure the quality of food, ventilation is very important.

2. Use Zanthoxylum pepper to prevent insects, in the actual process, some farmers will use breathable small cloth bags, wrap some pepper powder, put it in the grain, you can put more, it is harmless to the food, and the smell released by the pepper has the effect of preventing insects, which is relatively simple and trouble-free.

3. In the process of storing grain, put some garlic in different areas, because garlic is still allicin, in the storage process, it can also play a certain insect control effect, interested farmers can try.

4. For the granary with a small grain storage area, you can sprinkle a layer of plant ash at the bottom of the grain, and then spread a layer of plastic cloth on top of the plant ash, and then put in the grain, which can greatly reduce the pests at the bottom and reduce the mold at the bottom.

Causes of insects in home storage of grain

These bugs do not come from outside, but with rice, corn, mung beans and other grains. From sowing to harvesting, the farmer grows in the wild for 2-4 months. In such a long period of time, many insects began to come from all over the world and began to live in the process of growing in the banker.

They not only eat crops such as rice, wheat, corn and so on that are grown and grown to completion. It will also lay eggs on the dealer, so these bugs grow up with the dealer. By the time they are harvested, their eggs are already stored in crops such as rice, wheat, and corn.

1. Freezing method: You can put the grain together with the container containing the grain, put it in the refrigerator and freeze it for 24 hours, and then take it out directly.

2. Poplar leaf insecticide method: After the grain is insected, move the grain to a dry and sealed container, and put the freshly picked poplar leaves into the container and seal it together with the rice noodles. After four or five days, open the storage container to find that the larvae and eggs have been killed

Sichuan pepper is insect repellent because it is a natural antioxidant with a special fragrance. Rice worms are very sensitive to smells, and they are even more afraid of this special smell. Here's how:

Prepare a few small pieces of clean gauze, wrap the peppercorns, and place them in different positions such as the top, middle, and bottom of the grain.

4. Cool ventilation method: insert chopsticks into the grain of raw insects, and pull out the insects after the insects on the surface of the grain climb up. Then, spread the grain in a cool, ventilated place, and the bugs in the depths of the grain will crawl out of the warmer grain.

This method is simple and convenient, but it takes a long time to get rid of insects.

5. Enlarge garlic: After peeling off the garlic, disperse it into the grain, you can pour the grain into the grain container and enlarge the garlic at the same time, and put a few cloves in it at intervals.

1. First of all, put the purchased grain (rice, beans, etc.) in the freezer compartment of the refrigerator, freeze it for four hours, and freeze the eggs to death. Take an empty plastic oil drum and wash it to dry, canned the frozen grain (rice, beans, etc.) in a dry plastic oil drum, and cover it so that flying insects are not allowed to enter.

2. Put a small amount of dried kelp in the grain, which can absorb the moisture in the grain and prevent its insects from becoming moldy, and the kelp will become wet after use, and it can be dried and put in again, still maintaining the ability of moisture absorption and sterilization, and does not affect the eating.

3. Wrap some new peppercorns in gauze and put them in a rice bucket to repel insects and prevent insects.

4. If there are already worms, first put the rice in the refrigerator and freeze it for 24 hours, freeze the worms in the rice to death, and the worms will become lighter after freezing to death.

1. Low temperature. Below 14 degrees, the pest is inactive. , freezing will freeze to death.

2. If there is a lack of oxygen, the rice should be pumped out of the air, or the insect-free rice should be put in a clean plastic bucket and sealed with the lid to prevent insects.

3. Low-dose fumigation of aluminum phosphide can control pests.
