What should I do if my plant has aphids? What to do if the plant has aphids

1. Artificial prevention and control

In the early stage of aphid infestation, it is recommended to take manual control, the specific method is to brush off the aphids with a brush or brush, and bury the swept aphids in the potting soil.

2. Plant insect repellent

The special smell of leeks can be used to repel and control aphids. Planting leeks and sick flowers together can play an effective role in control.

3. Prevention and control of wind oil essence

Add 600 to 800 times of water to dilute the wind oil essence, pour it into the spray, and spray it on the pests to ensure that the insects are stained with liquid. This method has a high insecticidal rate, and it will not cause harm to plants, and it can also have a mosquito repellent effect.

4. Onion insect control method

Mash a small amount of onion, add about 500 grams of water, filter it after 24 hours, and spray it on the flowers. This method is not only effective in controlling aphids, but also has a certain effect on red spiders.

5. Washing powder insect repellent method

Take 3 to 4 grams of laundry detergent, add 100 grams of water to stir, spray 2 to 3 times, preferably continuously, it should be noted that neutral laundry detergent should be used.

Aphids can be sprayed. Use dish soap first to see if it can be cured: pour the dish soap into the watering can, add water to dilute, then shake the watering can vigorously until a large amount of foam is produced, and spray it on the aphid part of the pepper, about 3 times; Soak the dried chili peppers in water for 24 hours, pour the water into a watering can and spray them on the aphids; Take 3 to 4 grams of neutral laundry detergent and add 100 grams of water to dilute it, stir and spray it 2-3 times.

If the effect of dish soap treatment is not good, it is necessary to use medicine.

Use imidacloprid + enemy killing for control.

Imidacloprid can be sprayed or rinsed several times with soapy water can also be effective.

The main reason is that the ventilation problem has not been solved well, and the medication is only temporary.

A little imidacloprid can kill aphids and is safe for people.

With 20% imidacloprid you can kill aphids, planthoppers.

It can be controlled with low-toxicity pesticide imidacloprid, and can also be controlled with water soaked in cigarette butts.

Imidacloprid is sprayed for control, and the toxicity of imidacloprid is low.

1. Spraying agents: Plants have aphids, and they need to be sprayed with wind oil essence water or soapy water. 2. Wipe off pests:

Use a toothbrush to wipe aphids off the leaves of the plant and apply alcohol. 3. Repot pruning: Cut off the branches and leaves of the plant with serious insects, and replace the potting soil.

4. Ventilation environment: Place the plant in a ventilated place to make it grow healthily.

1. Spray the agent

Aphids grow on the plant, you need to add wind oil essence to clean water for dilution, and then put it into a sprayer, and spray it on the leaves of the plant to make the aphids die quickly, or spray the evenly stirred soapy water on the branches and leaves of the plant, you can spray it 2-3 times every other week to make the stickiness of the aphid disappear.

2. Wipe off pests:

When cultivating plants, if you find that there are aphids on the leaves of the plant, you should use a toothbrush or brush to wipe off the aphids on the leaves, and then use the diameter dipped in alcohol to repeatedly wipe the leaves of the plant to kill the larvae and eggs together, this method will not cause harm to the growth of the plant.

3. Replace the potting soil

After the plant grows aphids, it needs to be replaced immediately for the potting soil, you can use nutrient soil with good drainage and rich humus, and then mix carbendazim into the soil for disinfection and sterilization, reduce the probability of plant infection, and then you can plant the plant into the soil to promote its vigorous growth.

4. Suitable environment

When cultivating plants, if the environment is too closed and humid, it will lead to a large number of bacteria in the environment, which makes the branches and leaves of the plants easy to grow aphids, and it is necessary to place the plants outdoors in a ventilated and ventilated environment, or open the indoor windows for 5 hours a day to promote the healthy growth of plants.

Aphids can be sprayed. Use dish soap first to see if it can be cured: pour the dish soap into the watering can, add water to dilute, then shake the watering can vigorously until a large amount of foam is produced, and spray it on the aphid part of the pepper, about 3 times; Soak the dried chili peppers in water for 24 hours, pour the water into a watering can and spray them on the aphids; Take 3 to 4 grams of neutral laundry detergent and add 100 grams of water to dilute it, stir and spray it 2-3 times.

If the effect of dish soap treatment is not good, it is necessary to use medicine.

Imidacloprid can be sprayed or rinsed several times with soapy water can also be effective.

The main reason is that the ventilation problem has not been solved well, and the medication is only temporary.

It can be controlled with low-toxicity pesticide imidacloprid, and can also be controlled with water soaked in cigarette butts.

Imidacloprid is sprayed for control, and the toxicity of imidacloprid is low.

Large white spots when raising flowers? It's an aphid, let's get to work on it now.

1. If it is a family-raised flower, etc., the number is small, you can consider the following methods: a cigarette butt, add an appropriate amount of water and soak for 48 hours, take water and spray the foliage to achieve the purpose of killing aphids. 2. If it is a large-scale planting plant, it should be sprayed with pesticides, most aphids are sensitive to pesticides and are easy to eliminate, dimethoate, imidacloprid and pyrethroids.

Aphids grow in the soil and leaves of potted plants, and are generally up to millimeters in length, most about 2 millimeters. Adult aphids have wings and fly to the damp and dark places of potted plants, where they lay eggs in large quantities in the soil and other places, and after a while, the eggs will break out.

Indoor potted plants are susceptible to aphid infection, so check regularly for aphids, and if found, deal with them as soon as possible to prevent infection with other plants. The growth of plants is poor, the growth environment is not suitable, and they are generally attacked by aphids. The soil in which the plants are maintained contains insect eggs, which can lead to the appearance of aphids in the plants.

Less precipitation, higher temperatures, and relatively low humidity will all promote the derivation and reproduction of aphids. The large use of pesticides in agricultural production has led to a sharp decrease in the number of aphids, and the seven-star ladybugs and lacewings are rarely seen, which has accelerated the spread of aphids.

Evolution and distribution of aphids

It is likely that aphids appeared as early as 280 million years ago in the early Permian, when they probably fed on cycad plants, and the oldest fossils of aphids are from the Triassic period. The number of aphid species was once small, but it began to grow with the emergence of angiosperms 160 million years ago. Angiosperms also made aphids specific, and the abdominal canal of the aphid's organ did not appear until the Cretaceous.

Aphids are widely distributed, almost all over the world's wheat-producing countries, there are many kinds of aphids that harm wheat in our country, usually the more common and important are: wheat long tube aphid, wheat bifurcation aphid, millet tube aphid, no net long tube aphid. In China, except for the narrow distribution range of Aphid without net, the rest of the aphids are common in all wheat areas, but A. wheatensis and Aphid bidonum are often the most abundant and the most harmful.

In general, the density of Aphid is quite large in both north and south, but it is heavier in the north.
