How to control peanut garlic underground pests?

You can mix seeds with pesticides to sow seeds, and you can ask the agricultural material store when you buy them to know what pesticides are used.

Peanut seed dressing controls underground pests such as grubs, and ripe peanut fruits meet the production standards of green pollution-free agricultural products, which have been recognized by authoritative departments. In 2008, the Ministry of Agriculture focused on the promotion and release of the "2008 Agricultural Leading Varieties and Main Technologies Notice" in the "Notice on Agricultural Leading Varieties and Main Technologies" is one of the 50 main technologies. Before peanut sowing, the peanut seed dressing was carried out with the "Diying" phoxant, the flower growth was good, the fruit had no empty shell, and the grain was full, and the demonstration households were very happy.

Peanut seed dressing is easy to use, no need to sprinkle, irrigate, spray, save labor and time, replace the traditional methods such as sprinkling poisonous soil, irrigation, spraying, etc., so that farmers can bid farewell to the history of carrying medicine barrels to prevent and control peanut underground pests. It is a slow-release agent, which can achieve a season without pests in one seed dressing. At the same time, it can also achieve the purpose of promoting roots, strengthening seedlings, disease resistance, no premature aging, high yield, high quality, and no drug residues.

Earn three or four hundred yuan more per mu than in the past. At the same time, it reaches the level of green environmental protection. It has been well received and welcomed by the demonstration households.

It not only has a good control effect on grubs and needleworms, but also has a significant control effect on underground pests and diseases such as ground tigers, leek root maggots, garlic root maggots, mole crickets and root rot.

Underground pests, you can sprinkle poisonous soil and peanuts at the same time, phosphine is the best, and the underground effect lasts for 2 months. Garlic can be sown at the same time with rabbit dung, which is safer.

Garlic insect pests are mainly root insect pests, and root pests are rampant, which is the most common and most serious insect pest of garlic. There are as many as 12 kinds of pests that damage the roots, and 4 of them are the most serious, they are the onion seed fly, the leek late-eyed mushroom mosquito, the gray bell fly, and the small radish seed fly. Flies and leek late-eyed mushroom mosquitoes feed on the sap of young garlic bulbs in the upper layer of the ground surface at 1 4 cm or the larvae burrow into the garlic cloves to suck the damage, forming yellow-brown holes, which further cause the rotting of garlic cloves, the shrinking of garlic heads, and the cracking of garlic heads, resulting in economic losses.

When the insect is underground, it already hatches its eggs on the garlic. That's why there's a worm

Deterin granules: To control grubs, mix Deterin granules with the soil and sprinkle them in the field. Available:

To control root mites, spray diluted 1000 times of available thiophos. Octophos EC: To control bacteria and flies, spray 800 times of diluted phoxanthion EC.

Dichlorvos EC: Spray 80% dichlorvos EC to control tigers.

1. Deterin granules

Grubs are omnivorous pests, will eat the roots of garlic seedlings in the field, causing the whole plant to die, in order to control this insect, to remove the weeds in the field in time after the sprouting, and do a good job of water and fertilizer management, you can also mix the Deterin particles and soil, and then sprinkle on the roots of the field.

2. Available thion

Root mites and stem nematodes are two pests that can harm the fibrous roots and bulb endothelium of garlic, causing the plant to turn yellow, slow down the growth rate, and die when the disease is severe, further causing a reduction in yield.

3. Zinc sulfur and phosphorus emulsifiable concentrate

Bacterial flies are pests that often appear on the feces, which will harm the garlic cloves, especially in the swelling period of garlic, this pest will cause damage to the garlic cloves by drilling into the field through rotten debris, and the control of this pest can be sprayed with diluted phoxanthion EC 800 times.

4. Dichlorvos EC

Tiger is a common underground pest, mainly harming the underground part of the garlic and leaves, after being eaten there will be many small holes in the leaves, and can drill into the bulb, bite off the whole garlic plant, to prevent and control this disease, can be sprayed with 80% dichlorvos EC.

Garlic planting to control pests and diseases: mainly maggots, allium thrips and leaf miners, before garlic sowing, to turn the soil deeply, dry for more than 15 days, reduce the number of soil residual pests and diseases. The base fertilizer should be fully decomposed, eliminate the eggs in the manure and avoid the adult worms from laying eggs.

Garlic should be watered in time during the mother rot period, combined with irrigation and ammonia bicarbonate to reduce the egg laying of adults. Let's take a look at the three main pest control techniques!

1. Maggots: larvae of flies such as onion flies drill into the ground to burrow garlic bulb disc parts or false stems, causing rot and mildew, wilting of the aboveground parts, yellowing of leaf tips or yellowing of the whole plant, and death. During the adult occurrence period, 48% chlorpyrifos EC 2000 times or deltamethrin EC 3000 times can be sprayed for control.

During the peak spawning period, 90% crystal trichlorfon 500 times or 80% dichlorvos emulsifiable concentrate 600 times can be sprayed on the compost pile. During the larval damage period, 75% fly amine wettable powder, 40% phosphine emulsifiable concentrate, 48% chlorpyrifos emulsifiable concentrate, 5% flubellura emulsifiable concentrate 3000 times liquid can be used for root irrigation.

2. Allium thrips: often occurs in the warm and dry season, and occurs 6 to 10 generations a year. Adults and nymphs are long, small, yellowish or dark brown in color, and suck the sap on the leaves and sheaths of garlic, causing the leaves to fade green.

It can be sprayed with avermectin EC 2500 3000 times, or 20% fenvalerate EC 2000-3000 times.

3. Leaf miner fly: generally occurs in 4 generations a year, overwintering in the leaves of the host plant with larvae or pupa. The larvae are mostly harmed in the late autumn and April of the following year, sneaking into the leaves to feed on the mesophyll, causing the leaf surface to appear gray-white curved submersible channels.

During the growth period of garlic, the damaged leaves in the field should be removed in time, and they should be fertilized or burned to reduce the source of insects, and at the same time, 48% chlorpyrifos EC 1500 times, or 40% phoxanthion EC 1000 times liquid.

Methods of agricultural control of garlic insect pests

1. Select disease-resistant varieties, strictly select seeds before sowing, and eliminate diseased and insect garlic.

2. Reasonable crop rotation to avoid continuous cropping with onions, leeks and other allium crops.

3. Do a good job in fertilizer and water management, and timely cultivate and weed.

4. Scientific medicine: aphids: 3000 4000 times of 10% imidacloprid wettable powder can be used for continuous control 2 3 times, with an interval of 5 7 days each time. Apply fully decomposed organic fertilizer as base fertilizer, and garlic seeds and fertilizer should be properly separated; Root maggots are seriously harmed.

It can be dissolved with 750 grams of 90% crystal trichlorfon and 50 kg of water per mu, sprinkled on 750 kg of manure, mixed and applied; At the same time, when suffering from root maggots and grubs, 1000 times of 90% crystal trichlorfon can be used to spray the root soil of the plant. To control allium thrips and leaf miners, you can use suitable insecticide sprays.

Summary. Prevention and control methods: to reduce peanut grubs, we should focus on prevention, adopt agricultural control, physical control, chemical control, and combine killing adults and larvae to carry out comprehensive control.

1. Seed treatment: When sowing, 40% zinc sulfate can be used, and the seeds can be soaked for 2 hours according to the ratio of medicine, water and seed grains in the ratio of 1 20 1000, and then sown. You can also use 50 phosphine emulsifiable concentrate, according to the amount of 200 250 grams per mu, mix with fine sand, mix evenly, and make poisonous soil.

Sprinkle in the sowing hole.

2. Strengthen cultivation management and reasonable fertilization. Apply well-rotted farmyard manure. Intensive farming, scientific watering and fertilization, achieve a reasonable ratio of nitrogen, phosphorus and potassium fertilizer, properly control nitrogen fertilizer, increase phosphorus, potassium and micro fertilizer, promote the healthy growth of peanuts, and improve the ability of peanuts to resist pests and diseases.

How to treat the peanut underground pest grub.

Prevention and control methods: to reduce peanut grubs should be based on prevention, and comprehensive prevention and control should be carried out by using agricultural control, physical imitation and anti-radical treatment, chemical control, and a combination of killing adults and larvae. 1. Seed treatment:

When sowing, 40% zinc sulfate can be used to soak the seeds in the ratio of medicine, water and seed grains to 1 20 1000 for 2 hours, and then sow again. You can also use 50 phosphine emulsifiable concentrate, according to the amount of 200 250 grams per mu, mix with fine sand, mix evenly, and make poisonous soil. Sprinkle in the sowing hole.

2. Strengthen cultivation management and reasonable fertilization. Apply well-rotted farmyard manure. Intensive farming, scientific watering and fertilization, so that the reasonable ratio of nitrogen, phosphorus and potassium fertilizer, proper control of nitrogen fertilizer, increase the application of phosphorus, potassium and micro fertilizer, promote the healthy growth of peanuts, and improve the ability of peanuts to resist pests and diseases.

3. Chemical control. The middle and late July of the vigorous period of grub hatching, and the beginning of August when the young larval stage is quiet, is the best period for chemical control with medicine, which can be mixed with 20 25 kg of fine sand with 48 chlorpyrifos EC 250 and 400 ml of shanbu per mu, and applied around the peanut plant. or 800 times with 40% chlorpyrifos EC; Remove the sprinkler head and sprinkle the plant around the root of the spike plant.

The timing of application can be before the rain, or the liquid medicine can be mixed with 40 kg of water to spray the roots. Water immediately after application. It can effectively control the damage of grubs.

Garlic is an ingredient that we can't do without in our daily life, many people in the countryside will grow some garlic at home, and even people living in the city will use some potted plants or foam boxes to grow garlic.

The first thing to do is to choose healthy seeds. In the case of planting, in the case of purchasing, we try to find the kind that is healthier, looks very round, and has not been affected by diseases. When such seeds are planted, they reduce the chance of developing some pests and diseases.

This is followed by the strengthening of their day-to-day management methods after planting.

Ultimately, drugs are used for prevention, but it must be noted that the drugs used should be changed frequently to prevent the formation of antibodies. In general, in the early stage of garlic leaf blight, its leaves will gradually become withered or turned dry. Therefore, if you find this situation, you can use mancozeb wettable powder, an aqueous solution mixed with acetamiprid and promethine wettable powder to treat.

In the case of viral diseases, the color of the leaves will slowly change. Therefore, after detection, it can be prevented by applying a 500 times solution of viral infection or hydroxyl chain protein wettable powder.

During the harvest years, the supervision should be done well, the temperature should be controlled at 6 to 8 degrees, the ambient humidity should be 85%, and the stored burrows should be steamed with 12 grams of sulfur powder all day. During the harvesting process, the harvest cannot be made when the temperature in the field is high. 8 days before picking, spray thiophanate-methyl suspension.

To improve the resistance of the plant, you can spray a lot of plant cells with immune system drugs around the week before picking. If the body's immune system is strong, the reproduction of viral infections will be suppressed.

Mainly due to the damage of some underground pests, resulting in garlic root rot, such as garlic maggots, grubs, ground tigers, root mites, etc., preventive measures can be solved before sowing seeds, preventive measures can be used, can be used to irrigate the roots. The sowing date should be as early as possible, advanced to late August to early September, so that it can not only achieve the suitable temperature (16-20) required for seed germination, but also achieve 5-7 leaves before the wintering period, which can safely survive the winter.

For the same soil layer, I propose that it is best to carry out crop rotation to prevent the lack of fertilizer efficiency in the soil layer, and in the case of more comprehensive soil organic matter, they can grow and develop faster. It is necessary to add some organic fertilizer to it, which is more beneficial to their growth and development. And they must be planted effectively, their relative density manipulated, and immediately ditched and drained to reduce their temperature to ensure their healthy growth and development.

Prevention should begin before planting, eliminate the garlic with insect holes when sowing, pay attention to weeding every day, do not plant with green onions, and then spray a little insecticide prevention every once in a while, not too strong.

Pesticides can be sprayed, and then the soil can be loosened in time to ensure that the soil is loose and breathable.

It is necessary to water on time, choose disease-resistant varieties, and pay attention to water and fertilizer management, so as to avoid continuous cropping, so as to prevent diseases.
