What kind of medicine can be used to control stinging moths scale insects?

During the event, Li Zihai, director of Guosang Station of Chengde Forestry Bureau of Chengde City, Hebei Province, mentioned many times that a "bath medicine" is a special drug for the control of fruit tree diseases and pests.

Stone sulfur mixture - a variety of pests and diseasesThe main ingredient of stone sulfur mixture is calcium polysulfide, which has the ability to penetrate and erode the waxy layer of the epidermis of bacteria and pests, and forms a layer of film on the surface of the plant after spraying to protect the plant from the attack of the disease, and is suitable for spraying before or at the beginning of the disease of the plant.

Stone sulfur mixture has a wide spectrum of control, which can not only prevent and control powdery mildew, scab, anthracnose, rot disease, gum disease, rust and black spot disease of a variety of fruit trees, but also effective for the control of fruit tree red spiders, show ticks, scale insects and other pests and diseases. In terms of production, after winter pruning, the fruit trees will be sprayed and disinfected with stone sulfur mixture.

Abamectin is a high-efficiency, broad-spectrum antibiotic insecticide and acaricide, which has stomach toxicity and contact killing effect on insects and mites, without systemic effect, but has strong permeability on leaves, can kill pests under the leaf epidermis, and has a long residual effect period. Mites and insect larvae appear paralyzed after contact with the agent, do not move and do not eat, die after 2 or 4 days, have little residue on the surface of the plant, and have little damage to beneficial insects.

It can be used to control leaf mites, gall mites, tea yellow mites and various resistant aphids of fruit trees, vegetables, grains and other crops, and also has a certain control effect on diamondback moth, cabbage worm, leaf miner moth and other larvae.

Imidacloprid – stinging and sucking mouthparts pestImidacloprid is a nicotinic ultra-efficient insecticide, with the characteristics of broad spectrum, high efficiency, low toxicity and low residue, pests are not easy to produce resistance, safe for humans, animals, plants and natural enemies, and have multiple effects such as contact killing, stomach toxicity and internal absorption, after the pest is exposed to the agent, the normal conduction of the central nervous system is blocked, so that it is paralyzed and died.

It has a good control effect on aphids, planthoppers, leafhoppers and thrips with stinging and sucking mouthparts, but it is ineffective against nematodes and red spiders, harmful to bees, and it is forbidden to use it during the flowering period, and stop using it 15 to 20 days before harvest.

AcetamipridActamiprid has contact killing and stomach toxicity effects, and shows strong permeability in plant bodies. It has a wide spectrum of insecticidal spectrum, high activity, low dosage and long validity period, and is suitable for the prevention and control of hemipteran pests on fruit trees, vegetables and other crops, resulting in paralysis of insects and eventual death.

It can control all kinds of hemipteran insects, aphids, leafhoppers, whiteflies, scale insects, scale insects, etc., and is effective against diamondback moths, submarine moths, heartworms, longhorn beetles, and thrips. Soil treatment with granules can control underground pests.

Spiroethyl esterSpirometallethyl ester is a new type of insecticide and acaricide, which has two-way systemic conductivity, which can move up and down in the whole plant body to reach the leaf and bark, so as to control pests such as lettuce and cabbage on the inner leaves and fruit bark. It is highly effective and broad-spectrum, with a long validity period, and the effective prevention and treatment period can be as long as 8 weeks.

It can effectively control a variety of stinging and sucking mouthparts pests, such as aphids, leafhoppers, scale insects, psyllids, whiteflies, etc., and is relatively safe for important beneficial insects ladybugs, aphid-eating flies and parasitic wasps. It is commonly used in citrus to control red spiders and scale insects.

You can use plant-specific insecticides, evenly spray on the leaves of plants, and should not be watered during the medication, otherwise there is no effect, and it can be consolidated several times.

Chlorpyrifos, acetamiprid, stone sulfur mixture, etc., can be used to destroy scale insects. Dilute 1000 times, spray once every other week, and the scale insects will automatically fall off when they have an effect.

The occurrence of scale insects is inseparable from the growth environment of the monthly season, and in general, there are several points, such as temperature, rainfall and wind, which have a great impact on the population of scale insects. At 25 26, when the humidity is high, there will be a large number of outbreaks, and when the humidity is less than 15%, a large number of deaths will occur, so drought is not conducive to reproduction, and wind can make scale insects spread faster.

There are four schemes of mixing liquor with water, with a ratio of 1:2 . When treating insects, water the surface layer of the potting soil thoroughly. Scale insects begin to move at room temperature 7 in spring. It can be poured once in April, and then every half a month or so, and it is effective for 4 consecutive times.

Use 50 ml of vinegar (rice vinegar), soak a small cotton ball in vinegar, and gently rub it on the stems and leaves of the affected flowers and trees with a wet cotton ball to wipe off and kill the scale insects. This method is convenient and safe, which can not only achieve the purpose of insect control, but also make the damaged leaves green and shiny again.

Gently and repeatedly rubbing the diseased plant with alcohol can get rid of the scale insects, and it can be very clean and thorough. If you wipe the orchid leaves with alcohol, not only can you get rid of the scale insects, but also the larvae that are not clear to the naked eye, and they are completely killed, and the second year is rarely found to have scale insects as a pest, this method is simple, safe, and the effect is good.

Use diesel, laundry detergent and water to adjust the mother liquor in the ratio of :6, at this time the mother liquor contains 60%, milk-like, dilute the oil content of 30% with water, and carefully spray the scale insects on Milan, kumquat and cycad. After one week, most of the scale insects changed from fresh orange to shriveled state, indicating that this method has a good control effect on scale insects.

There is no way to kill scale insects, spray and sprinkle, two-pronged.

Methods of killing scale insects without drugs are:

1. You can use liquor to mix water, the ratio of liquor to water is 1:2, and the surface layer of potting soil can be watered thoroughly when treating insects. Scale insects begin to be active at room temperature 7 o'clock in spring, and can be watered once in mid-April, and then watered every half a month or so, and watered 4 times in a row to be effective.

2. You can use 50 ml of vinegar, put a small cotton ball into the vinegar and soak it, and gently rub the wet cotton ball soaked in vinegar on the stems and leaves of the damaged flowers and trees, and then wipe off the scale insects to kill. This method is convenient, safe, and also achieves the purpose of insect control, and can make the damaged leaves green and bright again.

3. You can use alcohol dipping cotton balls to gently wipe the diseased plants repeatedly, and you can also get rid of the scale insects, which is simple, safe and effective.

Hello, I'm glad you have a question about: what medicine is used to eliminate scale insects 1. "Scaleworm clearing" + "Qiqiang" spraying insecticide: each set is sprayed evenly with 100 kg of water, which strongly penetrates through the waxy layer of the insect body and quickly removes the stubborn scale insects.

2. Long-term insecticide: 40 kg of water per bottle, 10-20 trees below DBH can be watered, and they can be fully watered after irrigation. After the liquid medicine is absorbed by the root system, it is internally transmitted to all parts of the tree, and cached for a long time to form a comprehensive protective network, 360 degrees without dead angles to kill insects, and make up for the disadvantages of uneven spraying and incomplete control.

After effectively removing all scale insects in the tree, the agent will continue to play a role to control the recurrence of insect infestations throughout the year. Long-lasting root irrigation is also suitable for hedges, shrubs and flowers, and each bottle can be used to irrigate the roots with 200 kg of water. Long-term control of scale insects can also be used for root irrigation, as well as medicated fertilizer application of tunethamine and tunamamine.

Whether to use spirothiazinone or pyripropion:thiamethoxam.

Just follow what I've posted above. It is important that you read it carefully.

Two of those potions are better.

Excuse me, which two potions are you referring to?

Snails: thiazinone, or pyriprothiamethoxam.

These two comparisons: pyriprothiazam is better.

Hello dear, it is a pleasure to serve you, 1, Phosphine: Phosphine is a common drug for insecticide, which is not only safe, but also has a good effect, and can remove many common bugs. But there are also disadvantages, the disadvantage is that it smells a little pungent.

If you want to use it indoors, you still need to pay more attention. Sen Jian 2, thiamethoxam: this drug has little toxicity, no impact on human health, and also has a good insecticidal effect, Fengshi can be mixed with other agents, and the effect is better after mixing.

1. What kind of medicine to use 1. Phosphorus: This is a more commonly used drug for insecticide, which is relatively safe and can also have a good effect, and can remove a series of insects, the disadvantage is that the taste is a bit big, and the smell is more pungent, if you use it at home, you can pay attention to this.

2. Thiamethoxam: its toxicity is relatively small, has no effect on the human body, can play a highly effective insecticidal effect, and can be combined with other agents to kill insects, so that the effect will be better.

3. Silicone penetrant: it can have tension, penetrate into the pores of plants, the effect is very long-lasting, and it will not have an impact when it comes to rain, and the other two agents can completely penetrate the eggs and kill the eggs. In addition to spraying the leaves, spray the surface of the potting soil and irrigate the roots with clean water.

Second, what else can be done?

1. Alcohol: In addition to the medicine, you can also use the self-made method to mix water in the alcohol, pay attention to the proportion of water to be large, and then pour it to the position of the root, and wipe the leaves, so that it can be safer.

2. Vinegar: Vinegar is very suitable for plants that like an acidic environment, mix vinegar with water and rub the leaves.

3. Salt water: You can also use a brush dipped in salt water to slowly wipe the leaves.

Disinfect with alcohol and then apply anti-inflammatories.

The body hair of the larvae of the stinging moth is poisonous, so avoid contact with the insect body when working. If you are accidentally stung by a stinging moth, it is recommended to use a medical plaster to stick and pull out or use a sterilized needle to pull out the stinger first, then clean the wound with alcohol, and finally apply anti-inflammatory and hormone ointments.

The hazards of stinging moths.

1) The larvae of the young spiny moth eat the lower epidermis and mesophyll of the plant, resulting in irregular yellow patches on the leaves, and the gnawed leaves form a net.

2) When the larvae grow up, the leaves are eaten into notches, and when they are serious, the leaves are eaten up, and they germinate twice in autumn, affecting the growth and development of trees.

3) Stinging moths often eat leaves, which will reduce the photosynthesis of trees, increase water transpiration, and in severe cases, will cause branches or whole plants to die.

4) It should be noted that the larvae of the brown-edged green thorn moth have poisonous hairs, which will cause swelling and itching after human contact, which endangers human health.

Scale insects are the most common pests of camellia, often clustering on branches, leaves, and buds. The special mouthparts of adults and nymphs are inserted into the camellia leaves and branch tissues to absorb the juice, causing the branches and leaves to wither, and even the whole plant to die, and can induce disease, which is extremely harmful.

Scale insects are small insects, most of which have waxy secretions. Female and male aliens. The female has no wings, while the male has a pair of membranous forewings and the hindwings are specialized as balance sticks.

Scale insects have a strong reproductive ability and occur in multiple generations a year. The eggs hatch into nymphs, and after a short time of crawling, they form a shell and live in a fixed life. Scale insects have strong drug resistance, and it is difficult for general agents to enter, so it is difficult to prevent and control.

Therefore, once it happens, it is not easy to clean up.

The scale insects that harm camellia mainly include blowing scales, red wax scales and chaff scales.

Blowing scale: female adult body length 5 7 mm, oval, orange-red. Male adults are about 2 mm long and orange-red. The eggs are oblong, orange-yellow at first lay, and then orange-red.

Red wax scale: Female adult body is millimeter long, oblate, purplish-red. The back is raised and covered with a white waxy shell. The male adult is about 1 mm long and has a small, translucent shell. The oval is oval, pale yellow at first birth, purplish-red when hatching.

Adult female is about 2 mm long, round or oval, purplish-red. The shell is about 1 mm long, oblong, grayish-white or grayish-brown. Male adults are pale purple, with elongated shells and grayish-white. Oval or oblong-ovate, lavender.

Blowing scales and red wax scales live on camellia leaf stalks and twigs to absorb sap. The bran scale often adheres to the apical sprouts or the front and back of the leaves, and absorbs nutrients from the epidermis of the leaf sprouts. They use their mouthparts to insert branches and leaves to absorb the sap, causing the branches and leaves to wither yellow, and also excrete more sugar and wax, which is easy to make the camellia complicated with gray-black soot disease, which will cause the death of the whole camellia plant in serious cases.

Blowing scales and chaff scales reproduce for 2 to 3 generations a year, and overwinter on branches and leaves with eggs under fertilized adults or shells. The first generation nymph is born in late April. Hatched nymphs swarm on the back of the leaf and on the tender tips to harm.

The second generation moves to flower buds and branches in July and August. In the third generation, the chaff scale is born in September, and the blowing scale is born in October. The red wax scale reproduces only one generation per year, and hatches in late May, and the peak hatching season is mid-June, when nymphs swarm on the shoots.

Male adults begin to emerge in mid-August and damage the leaves. Female adults are mostly harmful on the branches, fertilized in November and crawl onto the branches for overwintering.

Control methods: 1) In the early stage of hatching of scale insects, before the waxy scale shell is formed, dilute it with 40% oxidized dimethoate emulsion with water 1200 times, spray on the front and back of camellia branches and leaves, spray once every 7 10 days, 2 3 times in a row, and spray evenly to be even. If the shell has already formed, it is difficult to spray it.

2) The shell has been formed, which can be brushed off with a soft brush, pinched to death with fingers, or combined with pruning, cutting off insect branches and leaves, and burning them intensively.

3) Scale insects can be treated with liquor, vinegar and urine. The urine should be stored for half a month and used after it has decomposed. Mix about 60 degrees of liquor with 2 times water. Dip cotton balls in white wine and vinegar and soak them on the scale insects of leaves and branches, and the effect is also very good.
