How does dried corn prevent insects? What s the best way to do it?

If you want to effectively prevent insects from dried corn, you must put it in a ventilated place; You can choose the method of cooling and drying, you can use the method of the drug center, you can also remove the impurities on the surface of the corn, or you can spray it with some insecticidal agents, and then dry it.

You can spray insecticides, you can also use pepper for insect repellent, the storage place should be low, the corn can be dried several times to reduce insect infestation, and pine branches can also be inserted into the corn pile for prevention.

It is necessary to spray pesticides regularly, and also pay attention to storing corn in a confined space, and be sure to lower the outside temperature. Remove the corn kernels in question.

Sichuan pepper insect repellent method:Prepare 30 grams of peppercorns, put them in a checkered net, divide them into 3 portions, wrap them in gauze, and put them in the eastern, central and western parts of the granary, and in less than a week, the pests will come out on their own.

Dry the corn as many times as you can:When the corn is not harvested, there will be a lot of small insect eggs on the corn plant, and the eyes will not be able to see at all. Before the corn is put into the warehouse for the first time, it should be dried for at least one week to reduce the moisture content in the corn kernels as much as possible.

After the corn is stored in the granary, it is dried every 3 months, each time to kill the eggs and reduce the moisture content inside. In this way, the breeding of insect pests can be prevented.

Spraying pesticides:Every time you dry corn on the ground, try to spread it out a little thinner, mix the insecticide with water with a concentration of 5%, stir evenly, spray it on the surface of the corn kernels with a sprayer, which is conducive to killing insect eggs, because many insect eggs are hidden in the cracks of the corn kernels, one thing to pay attention to is not to pollute the environment, and wash your hands immediately after the operation.

Storage to large grain purchasing stations:The advantages of large-scale grain purchasing station are good ventilation conditions, complete equipment, dry environment in the granary, etc., after harvesting every year, the corn is stored in the grain purchase point, although a certain amount of care fee will be charged, but it is always lower than the loss caused by the existence of the family, and when you want to sell the grain, sell it directly to this grain purchase point, saving the trouble of transporting grain back and forth, killing two birds with one stone.

Corn storage requires many methods, not to say that a single method can effectively prevent the generation of pests for a long time, another method can prevent pests from developing resistance, so a variety of methods should be mixed.

Here's how:

1. Reduce the temperature, below 18 degrees pests are almost inactive and do not reproduce.

2. Fumigate and kill insects with aluminum phosphide, and prevent insects in low dose. This is a method often used by grain depots.

3. Mix insect-free corn with the surface layer of insect-proof phosphorus to kill pests.

4. Isolate new corn without insects. The premise is that the grain storage container is strictly insecticidal and insecticide, and there are no insect eggs.

Corn worms need:

1. The appropriate temperature, generally pests need to be between 18 and 40 degrees.

2. Sufficient oxygen.

3. Stored grain pests can be killed by insecticides, but high residue agents can not be used in food, generally aluminum phosphide and insect-proof phosphorus, which is mostly used for insect control.

Precautions for corn storage.

1. Remove impurities.

Corn harvest often contains more impurities such as unripe grains, broken grains and cob fragments. The amount of respiration is large, the hygroscopicity is strong, the amount of bacteria is large, the void is small, and it is easy to accumulate damp heat and cause fever, mold and insect infestation. Therefore, after harvesting, corn must be sieved to remove impurities before being stored in storage.

2. Dry and moisture-proof.

The key to safe storage of corn is to improve the quality of storage and reduce the moisture of grain, so it is necessary to control the moisture and temperature conditions before storage. According to practice, corn contains water and has a temperature of about 35, which is generally safe to store. After harvesting, corn should be fully exposed to the sun or dried, and ventilation and humidity should be paid attention to during storage, and newly harvested corn should be kept dry and low temperature conditions to ensure safety.

3. Prevention and control of pests and diseases.

During the storage period of corn, it is necessary to check frequently and do a good job of mildew and insect control. When there is a sweet smell in the corn silo, it should be turned over or dried in time. Before the spring warm, the corn should be stored in a cold cap, which has a good effect on preventing moth pests.

The corn that has been infected with pests can be screened, and if the corn is combined with winter freezing and spring screening, the insect control effect is better.

Throw it away, it's all worms, can you still eat it, and it won't germinate when used as seeds.

The corn kernel storage method is to dry the corn (below the moisture) and store it after the corn is threshed. Autumn and winter, turn it over once in 10 days, ventilate and cool down, cover a layer of 10 12 cm thick dry locust leaves, rice bran, wheat bran and so on on before the end of March of the second year, cover it with broken sack pieces, and then wipe a layer of grass mud to seal, and the temperature can also be safely stored in the summer when the temperature reaches 35. In order to prevent corn insects, the following methods can also be used:

1) Select pine branches with high pine resin content, insert them vertically into the corn pile, determine the number of pine branches inserted according to the size of the tank and hoarding container, and insert 5 8 pieces into the container with a general diameter of 50 100 cm, and then cover and seal it.

2) Put a small cup containing 50 100 grams of sulfur powder in the jar or hoard containing the corn, light the sulfur and cover it tightly with a wooden or iron plate, and fumigate it every 3 months, the treated corn is not harmful to the human body.

Hello, I'm glad to answer for you, corn insect control has the following methods: First, be sure to completely dry the corn before storage. Find a thicker plastic bag in the shape of a bucket and tie one end tightly with a rope.

Then put the dried corn and some insects, mildew and safe medicines into the plastic bag together with the corn, and tie the other end of the plastic bag tightly.

Find a dry house and put a layer of bricks or other indestructible things on the bottom of the house to prevent pests. A sheet of iron is then placed in a bucket shape on the brick-covered ground, and a plastic bag full of corn is placed in a "tin bucket". Finally, use a wooden board or an iron sheet to cover the upper part of the "iron bucket" tightly.

Generally, our home users use the above methods to store corn, and my family has stored corn and millet for three years at the longest, and it has basically not deteriorated. However, there are some large-scale buyers or large households are made of cement and other building materials to make moisture-proof, waterproof, insect-proof corn warehouse, although the effect of this corn warehouse storage corn is good, but the cost is relatively large, this is up to your own consideration.

Hopefully, this answer will help you.

Put some peppercorns. Be careful not to overdo it.

Insect control methods for storing corn:

1. After threshing, it should be cooled to safe moisture (less than 14% in the Northeast and less than 13% in the other).

2. Try to place it in a low and dry environment, preferably with ventilation facilities and a sealed warehouse, and fully clean up insect eggs and other impurities before putting it to avoid infection, and check the grain situation in time in the hot and mildew rainy season (electronic temperature measurement is the best).

3. Ventilation and cooling (precipitation) should be carried out in winter when conditions permit, and large changes in temperature and temperature rise should be sealed before spring.

4. Use aluminum phosphide to prevent and improve pests under the guidance.

<>1. Thresh the corn cob, and then dry the grains until the moisture content of the state plum is less than 13%; Choose a dry, ventilated warehouse as the storage environment, and then clean up the debris in the warehouse.

2. Put the dried corn into the warehouse, and place an electronic thermometer in the warehouse, and check the grain situation in time when entering the hot season and the rainy season; After winter, it is necessary to ventilate in a timely manner in order to cool down the warehouse, and close the warehouse after the beginning of spring to prevent a large change in the temperature of the warehouse.
