To kill underground pests, you can choose the eight best tricks!

Trick 1: spray on the ground

Use the enemy to kill the tiger under the new rule of law as a conventional pesticide. The practice is: after work is finished in the evening, use a knapsack sprayer, use 30 buckets of water per hectare, add 2.5% of the enemy to kill 8 milliliters in each bucket of water, mix it into 2000 times the liquid, stir evenly, and spray all over the ground. As night falls, the temperature drops, evaporation is less, coupled with dew cover, the soil and seedlings are in a moist state, ensuring the efficacy. When all kinds of ground tiger larvae came out to harm the seedlings, they were in contact with the medicine. The stomach poison, heavy fumigation and contact with several arrows could be brought into full play, and all the ground tiger larvae were poisoned.

100% pest control effect.

The second trick: dressing seeds with chemicals.

Seed dressing with chemical agents is a simple and effective method to protect seeds and seedlings from underground pests, and the dosage is low, so it has the least impact on the environment. The commonly used agents are phoxim, parathion, dimethoate, methamidophos and so on.

Trick 3: dig the land deeply and cultivate it carefully.

Deep ploughing and turning soil is mainly through deep ploughing to change the living environment of underground pests, so that the pests in deep soil are exposed to the surface and threatened by high temperature, low temperature and drought, resulting in their death, or being preyed on by natural enemies, and reducing the population density of insects. Intensive tillage has a strong mechanical killing effect on underground pests, which directly leads to the death of pests.

Trick 4: irrigation to kill insects

Soil moisture can control the activities of underground pests. In the plots with better water sources, irrigation can be used to control underground pests without affecting the normal growth of crops. Ground tigers, mole crickets and crickets can all be killed by irrigation, while grubs will migrate to the depths of the soil and suspend the harm.

Trick 5: black light trap

The adults of ground tigers, beetles and grubs have a strong tendency towards black light. According to the actual situation of various places, they can be trapped and killed by some black lights during the peak period of adults.

Trick 6: poison bait

① traps and kills mole cricket with fried wheat bran and bean cake. Generally in the evening when there is no rain, dig holes in the field, put poison bait, pick up the next morning and be concentrated on the luring pests.

② rubbed 2.5kg of the new rapeseed cake, stir-fried it in the pan, put the fried rapeseed cake in a bucket, then poured the trichlorfon into the bucket and stuffed it for 3-5 minutes. In the evening, the poison bait was divided into small parts and scattered in the field of transplanting cotton field, and the poisoned ground tiger body could be seen early the next morning.

Trick 7: sprinkle the soil with medicine

Mix fine soil with 50% phoxim with a ratio of 1: 200 per hectare, sprinkle 450 cubic 500 kg of medicinal soil per hectare, sprinkle it in the row when sowing, or spread medicinal soil in a trench beside the root of the crop, and then cover the soil.

Trick 8: clean the countryside

Weeds are the main places for underground pests to hide or lay eggs. Weeds in the field should be removed in time after the previous crop harvest to reduce the number of overwintering larvae and pupae. Weeds in and around the field should be removed in time during crop growth in order to reduce the intermediate hosts of pests and destroy their spawning sites.
