The most effective way to treat aphids

First of all, it is necessary to determine the degree of tooth decay, which can be improved through later remediation, some teeth are only some decay on the surface, not deep into the root, timely cleaning and filling can be alleviated, if it is connected to the root of the tooth has already occurred decay, then it is necessary to consider whether to use dental implant technology.

Aphids are one of the main pests of crops, because aphids reproduce quickly, are numerous, and cause serious damage. Aphids are mainly concentrated on vegetable leaves, sucking the juice of leaves, causing vegetables to lose water and nutrients, making vegetable leaves yellow, and aphids can also transmit a variety of viruses in vegetables, causing plants to wilt and die in serious cases, resulting in a decline in product quality. Let's take a look at how to control aphids.

1.Pharmacological prevention.

When a large number of aphids are found, spray pesticides in time. Spray the plants 1 2 times with 1000 times of 50% marathon emulsion, or 1000 times of 50% pine borer emulsion, or 3000 times of 50% anti-aphid wettable powder, or 3000 times of exterminating emulsion, or 1500 2000 times of 40% imidacloprid aqueous solvent.

2.Artificial control.

In autumn and winter, whitewash the base of the trunk to prevent aphids from laying eggs; Combined with pruning, cut off the damaged branches and residual flowers, and burn them intensively to reduce the overwintering insect population; In winter, scrape or brush off the dense overwintering eggs on the bark, clean up the residual branches and leaves in time, and reduce the eggs of overwintering insects; When a small number of aphids are found on the flowers in spring, you can use a brush dipped in water to brush them off, or you can tilt the potted flowers and put them under tap water to rotate and rinse.

3.Protect predators.

There are many natural enemies of aphids, including ladybugs, lacewings, aphid flies and parasitic wasps, etc., which have a strong inhibitory effect on aphids. Try to apply as little broad-spectrum pesticides as possible, avoid applying pesticides during the peak period of natural enemy activities, and artificially raise and release aphid natural enemies if conditions permit.

1. Physical removal.

This method is very simple and crude, that is, it is directly cleaned with water. For some robust plants, such as potted flowers raised on the balcony at home, once infected with aphids, they must be removed in time, and they can be washed away with some relatively strong water, and they can be washed away by pinching the side of the water pipe with a water pipe, which can wash away the aphids. But be careful not to damage the plants.

For some branches and leaves that are infected with particularly many pests, they should be cut off and burned directly, or thrown into the trash. For the parts of the branches and leaves that are less aphid, you can rinse them with water.

2. Garlic solution.

Using our usual garlic, it is best to chop them and crush them into garlic paste, and then soak them in warm water for about a day or so, you can filter out the residue, properly mix them with water and then spray them to the place where they are infected with insect pests, and spray them evenly, so that you can effectively remove the pests.

In order to enhance the insecticidal effect, you can add two spoonfuls of alcohol to the solution, let them mix well, add a few drops of soapy water, and then spray the mist water to the infected area.

3. Yellow plate to trap aphids.

Winged adult aphids have a strong tropism to yellow and orange-yellow, and can make 15 cm and 20 cm yellow cardboard in size, and apply a layer of No. 10 engine oil or commonly used pesticides to control aphids on the cardboard, and insert or hang the yellow cardboard between the rows of vegetables and the top of the vegetables. The yellow plate of engine oil should be replaced in time after being full of aphids, and the yellow plate of the drug can make the aphids die when they touch the drug.

4. Silver ash film to avoid aphids.

Aphids have a strong avoidance of silver-gray color, and can hang some silver-gray plastic strips in the field or cover vegetables with silver-gray mulch.

5. Lime powder to kill aphids.

Sprinkle lime powder on the leaves with aphids, which will be killed quickly.

There are the following ways to clear it

1. Drug prevention and treatment.

When a large number of aphids are found, spray pesticides in time. 1000 times of 50% marathon emulsion, or 1000 times of 50% pine borer emulsion, with 1:6—1:

8 ratios to prepare chili water (boil for about half an hour), spray the plants 2 3 times continuously; For aphids such as peach powder aphid, which is coated with wax powder, 1% soapy water or washing powder should be added when applying any agent to increase adhesion and improve the control effect.

2. Artificial prevention and control.

In autumn and winter, whitewash the base of the trunk to prevent aphids from laying eggs; Combined with pruning, cut off the damaged branches and residual flowers, and burn them intensively to reduce the overwintering insect population; In winter, scrape or brush off the densely overwintering egg masses on the bark, clean up the residual branches and leaves in time, and reduce the eggs of overwintering insects; When a small number of aphids are found on flowers in spring, they can be brushed with a brush dipped in water.

3. Chili water.

Take 50 grams of dried red pepper, add about 1 kg of water and boil for 10-20 minutes, filter and spray the clear liquid, which can control aphids, red spiders, whiteflies, etc.

4. Color prevention and control.

Silver-gray has a strong aphid-avoidance ability, and can be hung with silver-gray plastic strips or silver-gray mulch film in the garden to avoid aphids, which has a good effect on aphid migratory infection virus.

Aphid range:

1. Wheat aphids are widely distributed, almost all over the world's wheat-producing countries, there are many kinds of aphids that harm wheat in China, usually more common and important are: wheat long tube aphid, wheat bifurcated aphid, millet tube aphid, no net long tube aphid.

2. In China, except for the narrow distribution range of Aphid without net, the rest are common in all wheat areas, but often the number of Aphid long-piped and Aphid is the most serious.

Spraying prevention and control is the most commonly used prevention and control method at present, with fast effect and high efficiency.

However, the duration of the general agent is only 7 15 days, after the effective period, the adults who migrate from elsewhere quickly carry out parthenogenetic reproduction under suitable environmental conditions, and the number of aphids increases geometrically, so in order to control its harm, it has to be sprayed again, generally every 7 days to spray once, I don't know how many times I need to spray in a season, which is why it is difficult for aphids to completely **.

You can also use willow branches to trap aphids. Aphids have a strong tropism to the smell emitted by willow, and a certain amount of willow branches can be tied into a handful and placed in the plant place where aphids occur in large quantities, so that a large number of aphids can be lured together to facilitate centralized killing.

Use plant ash liquid to avoid aphids, use 10 kg of plant ash, soak in 50 kg of water for 24 hours and then filter out, add 25 grams of 80% crystal trichlorfon in the filtrate (can also not be added), mix and spray, can control aphids, cabbage insects and other pests. Spray 1 time every 7 8 days, 3 times in a row, the effect is good.

Aphids are pure pests, it mainly harms crops and some vegetables, and it must be eliminated with the conventional pesticide imidacloprid and then mixed with a small amount of pesticide 1605 mixed spraying, so as to eliminate the vast majority of aphids.

Hello, glad to answer for you. Aphids can be treated in this way1Soil Treatment:

Soil treatment has the characteristics of high efficiency, long duration and good effect. It can be combined with the application of base fertilizer before crop sowing and transplanting, and can be used with 2% imidacloprid granules 500 1000 grams of mu, or 2% thiamethoxam granules 300 500 grams of mu, mixed with organic fertilizer and sprinkled, furrowed, or hole applied, because imidacloprid and thiamethoxam have strong systemic conductivity, after the agent is absorbed by the root system, it can be quickly transmitted to various parts such as stems and leaves, fruits, etc., and better protect the stems, leaves, and fruits from aphids. 2.

Seed treatment: The cost of seed dressing is low, the operation is simple, the effect is long, and the effect is good. Before sowing, the seed coating can be suspended with 60% imidacloprid according to 1:

200 change the ratio of 300 to the front bridge seed dressing, or 30% thiamethoxam seed treatment suspension according to the ratio of 1:400 500 seed dressing, the agent forms a circle of protection area around the seeds of confession, and through the internal conduction effect, the agent is transported to all parts to kill the pests of each part. 3.

% of imidacloprid wettable powder 1500 times liquid;

1000-2000 times of pyrethrin EC;

Spray 1000 times liquid spray prevention and control of fast killing.

Tooth decay, also known as tooth decay, protects teeth from continued tooth decay, first of all, you should develop a good brushing habit in order to reduce bacteria and plaque adhering to the tooth surface, brush your teeth in the morning and evening, rinse your mouth after meals, and use the internationally recognized pasteurization method.

Don't ask about this kind of thing here, be sure to go to a regular tertiary hospital for consultation. Based on the results of the examination, listen to the advice of a medical professional.
