The special drugs for underground pests and grubs include 50% phosphine emulsifiable concentrate, 50% parathion + 50% phosphine + and water, agricultural control, etc.
Octophans EC: 50% phosphine EC can be used to kill grubs, specifically by adding 10 times of water to spray on the soil, mixing the soil with this agent, and then applying the poisonous soil to the ditch, so that the grubs can be poisoned. Or use 3% vepardan, 3% methylisomerofol granules are also fine.
% parathion + 50% phosphine + and water: in addition to mixing soil with drugs, it can also be used to mix seeds, the specific drug selected is 50% parathion, 50% phosphine, and water, the ratio of seeds is 1:30:
400, so that after planting, it can avoid damage and can also treat some other pests.
3. Agricultural prevention and control: In addition to drug prevention and control, agricultural prevention and control methods can also be used. During the management of crops, organic fertilizer that is not well decomposed is not applied, and the soil is suppressed in a timely manner.
In areas where this pest is severe, the overwintering larvae are turned over to the surface to dry during autumn and winter, freezing to death or being killed by predators. In addition, the physical control method can also be used, and black light traps can be set to reduce the number of occurrences.
Morphological characteristics and living habits of grubs
The body of the grub is enlarged, larger than that of ordinary insects, and the body shape is curved in a C shape, mostly white, and a few are yellowish-white. The head is brown, the palate is prominent, and the abdomen is swollen. The body wall is soft and wrinkled, and the body surface is sparsely hairy.
The head is large and round, mostly yellowish-brown, with symmetrical bristles, and the number of bristles is often characteristic of species.
Grubs are one to two years old in one generation, and the larvae and adults overwinter in the soil, and the adults are beetles, which hide in the soil during the day and feed at 8-9 o'clock in the evening. Grubs have suspended animation and negative phototaxis, and have tropism to unrotted manure, and prefer to live in the planting areas of fatty root plants such as sugarcane, cassava, and sweet potatoes.
Larval grubs are always active underground and are closely related to soil temperature and humidity. When the soil temperature reaches 5 at 10 cm, it begins to rise to the soil surface, and is most active at 13-18 o'clock, and moves to the deep soil above 23, and then moves to the upper layer of the soil when the soil temperature drops to the suitable range for its activity in autumn.

Pesticides for the treatment of grubs: clothianidin suspension seed coating agent, insecticidal granules, chlorpyrifos EC, cyhalothrin, phoxanthion EC, matrine aqueous agent.
1. Clothianidin suspension seed coating agent: pesticide seed dressing to control grubs, choose clothianidin suspension seed coating agent, coat the seeds, the effect of preventing and controlling grubs is very good, wheat seeds, peanut seeds, corn seeds, etc., mix well in advance before sowing, sow after drying, you can also use chlorpyrifos microcyst suspension agent, seed dressing, etc., which has a good control effect on the larvae of beetle.
2. Insecticidal granules: sprinkle granules and insecticides before ploughing or transplanting, choose granules that are not easy to dissolve in water, which can play a long-term insecticidal effect in the soil, and common insecticidal granules include phosphine granules, clothianidin granules, chlorpyrifos granules and so on.
3. Chlorpyrifos EC: When planting, it can be combined with the application of organic fertilizer such as soybean cake and other cakes, and wheat bran can also be mixed with pesticides, it is best to fry soybean cake and wheat bran at least kilograms per mu, and then use 250 ml of 50% chlorpyrifos EC to stir evenly, before planting, mix with bottom fertilizer, spread evenly, and the control effect can reach more than 80 days.
4. High-efficiency cyhalothrin phosphine emulsifiable concentrate: eliminate the adult beetle, when a large number of beetles are stung every year, you can spray cyhalothrin only 1000 times of octathion emulsifiable concentrate in the evening, and the adult beetle lays fewer eggs, and the larvae of the scarab will be much less.
5. matrine water agent: after a large number of grubs occur in the field, the average number of grubs per square meter of the mountain is more than 5, and the harm to crops will rise significantly, resulting in economic losses.

There are a lot of tigers in the vegetable field how to sanitize.
Wait a minute, I'm glad to answer for you!! Underground pests can use pesticides such as imidacloprid, methylisosulfonate granules, phosphine capsule, phosphine fibre concentrate, etc. Common underground pests include root maggots, ground tigers, mole crickets, grubs, needleworms, etc.
How to apply the pesticide and the effect block is safe.
There are several pesticides to kill underground pests, you can choose according to the specific situation to see which one is said to be a medicine, that is, the larvae ex-wife to fight, not to say that the larvae have grown up and then get the insects in the ground as soon as they are dug up, all of them are adults, what to do.
Therefore, it is necessary to use these drugs for a **.

Summary. Hello dear, underground insects can use pesticides such as imidacloprid, Tiannuo line net, earth protection net, maggotin spirit, etc., when using pesticides, we must use them according to the actual situation.
Hello dear, underground insects can use pesticides such as imidacloprid, Tiannuo line net, land protection brigade quietly, and ground maggot, and when making the crack town imitate pesticides, it must be used in a targeted manner according to the actual situation.
The phosphine sage, the phosphine insecticidal spectrum is wide, the knockdown force is strong, it has the effect of contact killing and stomach toxicity, there is no systemic effect, it is unstable to light in the field, and it will soon decompose, so the residual infiltration period is short, and the residual danger is small.
Pesticides that kill underground pests 1, pesticides that kill underground pests include phosphine, chlorpyrifos, trichlorfon, avermectin and clothianidin and other agents, underground pests generally have ground tigers, mole crickets, grubs, needleworms, etc., and the main crops are cotton, soybeans, corn, vegetables and fruit trees. 2. Use 30 times the liquid of 90% crystal trichlorfon, mix the fried cornmeal and green reed leaves, sprinkle it on the ground around the crop in the evening, so that you can trap and kill the tiger, and use fried bean cake, corn and other feed kilograms per mu, 50% phosphine 50 grams, plus water and stir evenly in the evening sprinkled around the rhizosphere of crops in the field, and the control effect is better. 3. You can also use 30-40 ml of 25% bromohydroinulin to add 75 kg of water, Honghong sprays after the sunset in the digging zone, and the stems and leaves of the crop should be sprayed wet, sprayed 1-2 times, which can effectively kill the tiger.
4. Use 200-250 grams of 50% phoxanthion emulsifiable concentrate per mu, add 10 times of water and spray it on 25-30 kg of fine soil to make poisonous soil, apply it along the ridges, and then immediately carry out shallow hoeing, which can also effectively control underground pests.

Hello dear, subterranean insects refer to various pests that live and reproduce in the soil, such as aphids, bugs, termites, etc. Different types of pesticides are also different for different types of underground insects, so the selection of pesticides to kill underground insects needs to be determined according to the specific situation of Xungao. Here are some commonly used pesticide categories to kill underground insects:
1.Phosphate pesticides: dimethyl phosphate, trimethyl phosphate, etc., can block the nervous system of underground insects and make them die.
2.Carbamate pesticides, such as methamidophos, can interfere with the nerves and muscles of the insects, causing them to die.
3.Carbamate pesticides: such as imidacloprid, can block the nervous system of underground insects and achieve the effect of insecticide.
4.Nematicidal pesticides: such as carbendazim, nemazim, etc., can kill nematodes in the soil, thereby controlling underground insect pests.
It should be noted that the use of pesticides needs to be carried out in accordance with the dosage and use method on the instructions, and strictly abide by the safety regulations for use, so as not to cause harm to the human body and the environment. At the same time, the necessary identification and identification should be carried out before the pesticide is used to ensure that the pesticide selected is effective against the target pest and does not cause long-term effects on the environment and ecosystem.
Underground pests fire species: grubs: Scarab larvae feed on crops, young roots, stems, underground parts often bite or bite off the root hazard characteristics, the fracture is relatively neat, so that the seedlings wither and die, soybeans, sugar beet, sorghum are more seriously damaged. >>>More
When antibiotics are used to control termites in China, avermectin and derived ivermectin are mostly used. In the laboratory test, the use of a concentration of 20mg kg avermectin can eliminate termites, 4 5 days after the use of the drug is the peak period of termite death, the mortality rate is 32%, each termite contact with the dose of G will make termites appear semi-lethal, will not pollute the natural environment. >>>More
Planthoppers are migratory pests The most important thing should be unified control and control Controlling the source of the plant is the key At present, the source of planthopper is mainly from Yunnan, Guangxi and Southeast Asian countries. >>>More
