How to eradicate or minimize scale insects?

1) If there are other plants in the house, they should be removed from the house in the winter and taken out of the house. By the way, the soil in each pot is turned over and the soil is disinfected again to reduce the number of eggs and nymphs overwintering.

2) Use liquor to water, the ratio is 1 2, and water the surface layer of the potting soil when treating insects. Scale insects begin to move at room temperature 7 in spring. It can be watered once in April, and then once every half month or so, and it is effective for 4 consecutive times.

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

4) Gently rubbing the diseased plant with alcohol can get rid of the scale insects, and the removal is very clean and thorough. For example, when rubbing the diseased leaves of orchids with alcohol, not only can the scale insects be removed, but even the larvae that are not visible to the naked eye can be completely killed. The above are simple physical control methods, which are convenient, simple and fast, but some corners are difficult to clean.

At this time, you can use a little potion to consolidate the effect, otherwise the little bugs will come back if you are careless. Therefore, it is necessary to spray several times during the peak hatching period of nymphs, and it is recommended here: spray 40 dimethoate EC 1000 times or 2 5 kung fu EC 4000 times, 20 dissolix EC 4000-5000 times, 10 cypermethrin EC 1000-2000 times, etc., spray once every 7 to 10 days, 2 to 3 times in a row, which can effectively prevent the harm of scale insects.

or spray 40% acetinos. Poison (Guoguang Bizhi) emulsifiable concentrate 2000-3000 times liquid for prevention, kill insect eggs, reduce the number of hatched insects. If you add human laundry detergent when spraying, it will increase the spreadability, and the effect will be better.

It can also be applied to the root, that is, 15-25 cm diameter flower pots buried with ferdigram granules or 3 aldicarb 100 ml, can receive satisfactory results. The above agents are selected by themselves, and the dosage is relatively reduced. <>

The main way for insecticides to kill pests is contact killing, that is, the agent penetrates the skin of the pest and enters the body of the insect to kill the pest; Stomach poisoning, that is, the agent enters the digestive tract with the pest's food, resulting in the death of pest poisoning; Fumigation, i.e., the agent volatilizes or enters the air by other methods (such as combustion) and enters the insect body through the insect respiratory system, resulting in the death of the pest; Systemic medicine, that is, the agent enters the plant body through the roots or leaves of the plant, and conducts or metabolizes into more toxic substances in the plant body, when the pest eats the plant juice or leaves by stinging or chewing, the agent can enter the insect body to kill the pest. Therefore, when choosing pesticides, the corresponding pesticides should be used according to the species, living habits and feeding methods of the pests to effectively kill the pests. It is known that scale insects have waxy scale shells outside the body, and it is difficult to eliminate them by contact; It usually sucks sap on the leaves or stems of plants for survival, and the stomach poison insecticidal efficiency that stays on the fleshy surface is also low (in general); The method of fumigation has not been tried, and some meat friends have studied this and can popularize science.

So personally, I think that the effect of systemic medicine will be good, and it will be the case after trying it. <>

1. If a small number of scale insects are found, they can be manually removed and directly eliminated.

2. If there are a large number of scale insects, you can choose to discard the plants with raw insects and throw them away together with the pots.

3. You can also use the insecticide of scale insects, and pay attention to the concentration of insecticides should be diluted before spraying.

4. In the larval stage, scale insects can be sprayed with low-toxicity agents such as flower protection, rapid culling, and matrine, which can have a good effect. When it comes to the adult stage, these agents can play a certain role, but it is difficult to **, and I still feel that I have not killed it after using it. At this time, three agents can be used: phosphorus, thiamethoxam, and organosilicon high penetrant, which cannot be used alone, and need to be used alternately to play the best role.

Extermination method: When the number of scale insects is not large, such as a few hypertrophic scale insects on the back of the stem and leaves, if it is not serious, you can use a needle, tweezers, toothpicks and other small tools to pick and prick to death.

Vinegar method: Wet the vinegar diluted about 500 times with a cotton swab, and then gently wipe the insect infestation, which can wipe off the scale insects and eliminate them, which is only suitable for the situation that the insect infestation is not serious.

Alcohol method: If the number of scale insects is too large and the leaf surface is densely packed with a large area, you can use a cotton swab or brush to dip the concentration of alcohol above 75% and wipe the insect infestation site repeatedly, which can effectively remove the scale scale insects.

Answer: If you want to completely eliminate the scale insect, you need to spray it with a special drug in the early stage of the plant disease, the scale insect is very harmful, and if it is not eliminated in time, it is easy to cause the plant to wither and die, if you want to avoid it from producing scale insect, you need to cut off the excess branches and leaves during daily maintenance, and apply thin fertilizer frequently during the plant growth period.

Scale insect is a pest that harms plants, if you want to completely eliminate it, we need to use special insecticides to spray the plant in the early stage of the disease, such as "cocoon must be cured" 750-1000 times liquid, etc., generally every 5-7 days can be completely eliminated by spraying twice in a row.

Indoor flowers and plants are susceptible to scale insects? Teach you quick solutions and prevention.

To prevent scale insects, it is necessary to give the plant a suitable growth environment, reasonable watering and fertilization during the maintenance period, and to keep the environment ventilated. During the growth period, spray the plant with fungicide once between 20 and 30 days, which can effectively prevent pests and diseases. If there are scale insects on the plant, it is necessary to cut off the leaves and branches in time, and then spray the plant.

Scale insects mostly occur in spring or summer, and plants are susceptible to scale insects in a high-temperature, dry and closed environment. In order to avoid the infestation of scale insects, reasonable watering and fertilization are required during the maintenance period, which can enhance the disease resistance of plants. During the maintenance period, the windows should be opened frequently to maintain indoor air circulation.

During the maintenance period, regular spraying of fungicides on plants can effectively prevent pests and diseases. During the curing period, the plant can be sprayed with a fungicide once between 20 and 30 days, such as chlorothalonil or carbendazim. Do not put the plant in a sunny place after spraying, you can put it in a cool and ventilated place indoors for maintenance.

If the plant is attacked by scale insects during the growth period, it is necessary to cut off the leaves and branches of the plant and burn them intensively to cut off the source of infection. If there are a small number of scale insects on the stems and leaves of the plant, you can use soapy water, washing powder, pepper water, cigarette butt water or pepper water to remove insects.

If there are a large number of scale insects on the stems and leaves of the plant, it is necessary to spray the plant with relevant chemicals to remove the insects. You can spray plants with chemical agents such as carbendazim, flower protector, worm forest or rapid culling, and the agent can be sprayed once for 1 time between 7 and 10 days, and after spraying 3 or 4 times in a row, it can inhibit pests and make the plant recover.

The control of scale insects is generally carried out in the egg stage and nymph stage, specifically from late April to the end of June every year. Control method: During the nymph stage, use 4000-5000 times of 20% emulsifiable concentrate, or 10% cypermethrin emulsifiable concentrate 1000-2000 times, or 40% dimethoate emulsifiable concentrate 1000 times, or 4000 times of kung fu emulsifiable concentrate for spraying, spray once every 7-10 days, and spray 2-3 times continuously.

1. The best time for the prevention and control of scale insects every year

1. The control of scale insects is generally carried out in the egg stage and nymph stage, because after the scale insects emerge into adults, the elytra on their back will secrete a waxy layer to protect themselves, and it is difficult for the sprayed drugs to enter the body of the pest and play a role.

2. There are many species of scale insects, but most of the first generation of nymphs are concentrated in late April to the end of June, which is the best period for the prevention and control of scale insects, in addition, from mid-July to the end of September, it is necessary to pay attention to the prevention and control of the second generation of scale scale insects and nymphs, and the specific control time needs to be adjusted according to the species of scale insects.

3. Blowing scales: In the northern region, the peak period of the first generation of eggs and nymphs is from mid to late April to June, and the peak period of the second generation of eggs and nymphs is from mid-July to September. In the southern region, the first generation of eggs and nymphs blooms from early March to May, the second generation of eggs and nymphs blooms from mid to early May to late July, and the third generation of eggs and nymphs bloom from mid-August to mid-October.

4. Sagittal scale: The peak period of nymphs is mainly 3-4 time periods (3-4 generation areas), which are mid-April, late June to early July, early to mid-September, and early December.

5. Fur scale: There are three main time periods for nymphs, namely late May to early June, late July to early August, and early to mid-September.

6. Red wax scale: the peak hatching period of eggs is from late May to mid-June.

7. Japanese turtle wax scale: the peak hatching period of insect eggs is around late June.

8. Pear scale: The peak period of nymphs is mainly in three time periods, namely early to mid-June, late July to early September, and September to early November.

9. Mulberry white scale: the nymph hatching period is mainly in early to mid-May, mid-to-late July, and early to mid-September.

10. Mealybug: The peak hatching period of larvae is mid to late May, mid to late July, and late August.

2. How can scale insects be completely eliminated?

1. In the nymph stage, use 1000 times of 40% oxidized dimethoate EC, or 4000 times of kung fu emulsifiable concentrate, or 4000-5000 times of 20% dimethoate emulsifiable concentrate, or 10% cypermethrin emulsifiable concentrate 1000-2000 times of liquid for spraying, spray once every 7-10 days, and spray 2-3 times continuously (laundry detergent can be added to the drug to increase the expandability of the drug).

2. In the early stage of egg hatching, 4000 times of spiromethane ethyl ester suspension + 2000 times of 5% acetamiprid were used for prevention and control.

3. In winter or early spring, spray 3-5 degrees of stone sulfur mixture to eliminate overwintering insect eggs.

4. At the peak of the occurrence of scale scale insects, use 800-1000 times of 40% melt scale emulsifiable concentrate + 20ml of Jiexiaoli spray for control.

Alcohol.

If you want to kill scale insects, you can use white vinegar and alcohol, compared to the effect of alcohol is better than white vinegar, whether it is alcohol or white vinegar, as long as the use method is correct, you can effectively get rid of scale insects, you can use an appropriate amount of water to dilute the alcohol, and then water it at the position of the root system of the plant, use it once every half a month, or wipe the leaves with a towel dipped in the solution, which can also play an insecticidal role.

Precautions for removing scale insects.

Scale insects are common insect pests of flowers and plants, which mostly occur in spring and summer, and plants with poor growth are generally attacked by scale insects. If there are a small number of scale insects on the leaves of the plant at the initial stage, you can spray pepper water, soapy water, cigarette butt water or pepper water on the flowers and plants, and spray them continuously for 3 or 4 times to get rid of the pests.

If there are a large number of scale insects on the leaves of the plant, the plant needs to be pruned and sprayed to remove insects. Use a sterilized knife to cut off the branches and leaves of the plant and burn them intensively to cut off the source of infection. After pruning, the plant can be sprayed with carbendazim, chlorothalonil or imidacloprid and other agents, sprayed once in 7 10 days, and sprayed 3 times in a row to get rid of pests.

Methods to completely eradicate scale insects:

According to the morphological characteristics of scale insects, the first choice for the control of this type of pest is the agent with super systemic and osmotic effect, such as "scale must be treated" 750 1000 times liquid spraying, after the liquid is absorbed by the tree, the scale insect sucks the poisonous tree sap and dies, and the insecticidal effect is good.

The medication was used in the afternoon when the temperature was high, and the interval was 5 to 7 days. For tall trees that are difficult to spray with the solution, the "tree insecticide" can be injected in the middle and upper part of the trunk, and the solution can be transported and conducted to the top through the xylem duct, which has obvious effect on the scale insects with large insect age, thick waxy layer and difficult to control, simple operation and thorough control.

The first is to strengthen quarantine measures, because under natural conditions, scale insects live a fixed life and are generally inactive or rarely active, so their own transmission ability is limited, and their distribution is very limited. However, due to the rapid development of the flower industry, scale insects are spread with the transportation, introduction, and exchange of flower seedlings, so quarantine must be strengthened to strictly avoid the introduction or removal of insect-bearing seedlings. When scale insects are found, effective measures should be taken to eliminate them immediately; When you find that there are scale insects on individual leaves or branches, you can gently brush them off with a soft brush or wipe them off with cotton balls and cloth balls, or you can combine pruning to cut off insect leaves and branches.

It is required to be brushed, cut, burned in a centralized manner, and not littered; When the scale insect occurs in large quantities, it is necessary to use pesticides to prevent and control them, mainly to spray them during the egg incubation period, because the scale shells have not yet formed or thickened at this time, and they are killed with pesticides. If the wax shell has formed, the spray is not good. The agent can be 40% dimethoate, 50% malathion, 25% imithion emulsion, 80% dichlorvos emulsifiable concentrate 1000 times liquid, sprayed every 7 to 10 days, 2 to 3 times in a row; If conditions permit, the natural enemies of scale insects can be stocked, such as the Australian ladybug can prey on the cotton scale scale worm, the large red ladybug can prey on the grass chloride scale, and the red-spotted lip ladybug can prey on the Japanese turtle wax scale, brown leaf garden scale, etc.

To control scale insects: use liquor mixed with water, the ratio is 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 wiping the diseased plant with sprinkler sperm can get rid of the scale insects, and it can be removed very cleanly and thoroughly.

If you wipe the orchid disease leaves with sprinkler, not only can the scale insects be removed, that is, the larvae that are not clear to the naked eye, they are also 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, washing powder, water according to the ratio of 10::6 to adjust the mother liquor, 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 cycads.

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.
