What are the medicines for blind bugs? Special drugs for the prevention and control of green blind b

Methods of prevention and control.

1) Kill the adult insects that have already formed: in early spring, winter and late autumn.

During the overwintering period of the adults, the adults do not go to the activity, or in the evening or in the morning when the flight of the adults is relatively poor, to hunt and kill, which can greatly reduce the overwintering adults and reduce the amount of occurrence.

2) Removal of egg mass: The eggs laid by the rice green bug are lumpy, most of which appear on the leaves of peppers, and before the larvae go to hatch, combined with the operation in the field, the egg masses are removed, which can effectively reduce the harm of the larvae. <>

3) Chemical control: most of the nymphs.

At the beginning of hatching, most of the nymphs are concentrated near the egg shell and have not yet dispersed to use the drug, and 45% malathion can be selected.

Emulsifiable concentrate is about 500 600 times liquid, or 5% cis cypermethrin emulsifiable concentrate is about 700 1000 times liquid, or 26% chlorofluoroacetamiprid water dispersible granules are about 3000 4000 times liquid to spray for control.

When the occurrence of rice green bugs is more serious, 20% dinotefuran can be obtained.

Soluble granules are about 2000 times the solution, or 40% fiprofen ethyl polysine water dispersible granules are about 2000 3000 times, or 22% sulfoxapyr suspension is about 4000 5000 times the liquid, after 4 o'clock in the afternoon to carry out the control, depending on the severity of the occurrence of pests, can be sprayed again after 7 days, basically can quickly control the spread and harm. It can also be very good to inhibit the sucking of pests. <>

What is a blind bug.

The blind bug is what everyone calls a "fart bug."

Bugs. "Stinky Niangniang", etc., is a hemiptera.

The main species of pests of the family Elephantidae are the three-spotted blind bug and the green blind bug.

Alfalfa blind bugs and other insects are the main pests on pear trees, apples, jujube trees, peach trees, cotton and other crops in summer and autumn, this pest can harm the young stems, leaves, fruits and other parts, resulting in the growth and development of the plant has been hindered, and the fruit has no edible value, resulting in huge losses. <>

Symptoms of harm.

The main way of appearance of blind bugs is that nymphs and adults suck the growth points, leaves, young fruits and flower buds of the plants.

In case the blade is damaged, after the blade arrives, there will be a lot of small holes on the blade, and in serious cases, the blade may be twisted to deformation and there is no way to flatten; If the growth point is damaged, the growth point will be distorted, atrophy, and may die in severe cases; In the event that a young fruit is damaged, there will be spots on the surface of the fruit, and the damaged part will stop developing or develop slowly, and it will become a deformed fruit, which will cause the young fruit to fall off, and even if it is ripe, the fruit cannot be eaten.

For the control of these pests and diseases, it is best to use chlorine fluorine. Acetamiprid water dispersible granules for control, why do you say that? Because this insecticide is first of all particularly dispersed and can be used for large-scale farmland control, and secondly, it has strong penetration and can kill these pests very effectively.

Blind bugs can be used, acetamiprid, imidacloprid, thiamethoxam, all of which have the best effect in combination with avermectin.

The agents used to control blind bugs are: cyhalothrin, cyanoprofenophos, mala phosphine, chlorpyrifos, fiprofenide, etc.

The special drugs for the control of green blind bugs include: chlorantrancyan, imidacloprid, acetamiprid, pymetrozine and thiamethoxam

1.Chloranthacyan. It is a commonly used drug for the prevention and control of green blind bugs, and has shown very good effects in terms of duration and other aspects, but due to the negative impact on groundwater and bees, the state has stopped spraying and application.

2.Imidacloprid. Compared with similar drugs, the market is early, farmers have an application base, the price is relatively cheap, cost-effective, farmers are willing to use, and there are many varieties of dosage forms.

The disadvantage is that in addition to killing bees, the green blind bug is suspected to be resistant to it, the control effect tends to decrease, and the market purchase volume declines.

3.Acetamiprid. There are many similarities with the role of imidacloprid, the low temperature resistance is better than the former, and the current market dosage is relatively small, and it is a slow but certain market for the agent.

4.Pymetrozine. It has a unique mode of action, has a long duration of effect, and is harmful to beneficial insects, but the complete death time of the green blind bug is late after the medicine.

5.Thiamethoxam. The market is later than imidacloprid, the insecticidal fruit, the duration of effect is better than that of imidacloprid, and the fast-acting effect is significantly better than that of pymetrozine or other mold removal agents of the same kind, although the cost is slightly higher, but farmers are willing to accept it.

Prevention and control methods.

Catch the adult worms and remove the egg masses.

When the fruit begins to swell rapidly, spray the first spray to protect the fruit, and then at least once a month. It can be used 800 times of 90% trichlorfon, 1000 times of 40% oxidized dimethoate, 20 00 times of 5% Pepsi, or 1500 times of farmland.

Blind bugs are best beaten with flufenamide.

In May every year, when the temperature reaches more than 15 and the humidity is higher than 60%, the eggs of the blind bug begin to hatch, and it is also the time for the prevention and control of cotton bud worms. Flufenamide is a new type of pyridinamide insect growth regulator insecticide, mainly for the control of aphids and other pests of stinging and sucking mouthparts, and can be used to control blind bugs.

When planting crops, it should not be mixed with sugar beet and sugar cane, nor can it be planted close to sugar beet and sugar cane fields. Therefore, it is necessary to keep field crops ventilated and breathable, dehumidification and cooling, and the soil should be cleared and drained, cultivated and weeded, and the soil should be soft and permeable, and the water content should not be too large, and the soil is not easy to be too wet.

Hazards of blind bugs

In the cotton area of northern China, the feeding habits of cotton blind bugs are very mixed, and its hosts mainly include cotton, kenaf, alfalfa, beans, corn, millet, sorghum, etc. Blind bugs and beetles harm cotton for a long time, from seedlings to grow into green bells, the damage period is more than 3 months, but the cotton flowering period is the most serious. It uses adults and nymphs to suck the juice of young cotton tissues with stinging and sucking mouthparts, causing various damages.

If the growth point of the cotyledon stage is damaged and becomes black and scorched, it will not regenerate new shoots, forming "male cotton", if the growth point is damaged and dead after the appearance of true leaves, many adventitious buds will grow on the side, forming "broken heads" or "broom seedlings". If the young leaves are killed, black dots appear first, so that the local tissues are necrotic, and as the leaves grow, holes are formed, and the masses call them "broken leaf crazy" and "rotten leaves". If the young bud is killed, it first turns yellow-brown to black-brown, and then withers and falls off.

Thiamethoxam. The effect of thiamethoxam is better, there is no Li Qiao potato is too big, the speed of insect removal is very fast, it is the best, and it can be used according to the manufacturer's recommended dosage. Green blind bugs, belonging to the order Hemiptera, blind bugs.

Also known as mosaic insects, small bed bugs, etc. It is distributed in all cotton areas of the country. It is the dominant species of a variety of blind bugs and crubs that harm cotton in the Yellow River Basin and the Yangtze River Basin in China.

The hosts are cotton, mulberry, jujube, grape, hemp, beans, corn, potatoes, melons, alfalfa, medicinal plants, flowers, artemisia, cruciferous vegetables, etc.
