What should I do if a potted pomegranate tree has bugs?

1. Artificial anti-aphid method, in the early stage of aphids, take artificial anti-aphids, brush off the aphids with brushes and brushes, and bury them in the potting soil. 2. Plant repellent aphid method, the smell of leeks has a repellent effect on aphids, and planting them with flowers can reduce the number and harm of aphids. 3. Pepper anti-aphid method, use 50 grams of fresh chili pepper or dried red pepper, add 30 to 50 grams of water, boil for about half an hour, and spray the affected plants with its filtrate to have special effects.

4. Washing powder anti-aphid method, 3 to 4 grams of washing powder, add 100 grams of water, stir into a solution, spray 2 to 3 times continuously, and the control effect is 100%. Selective laundry detergent should be used. 5. Wind oil essence anti-aphid method, add 600 to 800 times of water solution with "wind oil essence", and spray the pests carefully with a sprayer to make the insect body stained with the potion.

The effect of killing aphids and scale insects and other pests is more than 95%, and there will be no pesticide damage to plants. 6. Yellow board trapping and anti-aphid method, using a piece of cardboard or wood with a length of 20 cm and a width of 15 cm, pasting yellow paper on it, and then applying a layer of butter on the yellow paper to make a booby trap board, inserting the booby trap board between the flower pots, and using the aphid's tropism to yellow, the aphids are glued to the booby trap board to achieve the purpose of eliminating aphids. 7. Green onion liquid anti-aphid method:

Take 1 kg of green onion leaves, dry and grind them into powder, add kilograms of water, soak and filter them and spray them to prevent aphids and snails. 8. Urine lotion mixture anti-aphid method, take an appropriate amount of water, add a little washing powder and urea, prepare a urine lotion mixture, spray it on the flowers with a small sprayer, spray it after 5 o'clock in the afternoon every day, spray it for 2-3 days, which can effectively control aphids.

Then prevent it. However, it should be noted that the medication for different insect pests is also different.

1. Physical booby-trapping: When physical booby trapping is aimed at a small number of pests, it can not only save costs, but also the effect will not be very bad. For example, whiteflies are a disease-prone species of guava and have a strong tendency to yellow.

So before this pest does not multiply in large numbers, it can be carried out by making a homemade yellow plate for intensive booby-trapping. 2. Chemical insecticide: In the planting process, if a large number of stubborn insect pests are encountered, the chemical insecticide method will be effective faster and more durable.

Pay attention to the targeted application of insecticides. An 800-fold dilution of acetamiprid with 3% content can kill whitefly. For peach moths, you can use 2000-fold diluted kung fu emulsifiable concentrate.

For aphids, 25% prochlorfen, diluted 1000 times, is often used.

In the process of planting, pesticides must be sprayed in a timely manner, and pesticides must be sprayed regularly, so as to prevent well.

When planting pomegranate fruits, spray a little pesticide on the ground first, and spray pesticides on time according to the growth of pomegranate fruits.

Guava fruit trees are suitable for tropical climates, are afraid of frost, and have general temperatures.

At 1 -2 o'clock, the young tree will freeze to death, and it is suitable to grow at a temperature of 15 or more. The soil requirements are not strict, sandy loam, yellow clay can be planted. Guava is a highly adaptable tropical fruit tree, and the insect pests of guava mainly include aphids and scale insects.

Wood moths, beetles, fruit flies.

Among them, fruit flies harm fruits, easily cause fruit rot, and can survive in fruits. Female flies prefer to lay eggs on near-ripe fruits, and the hatching larvae burrow into the pulp.

<> the soil was treated with 25% parathion microcapsules or phosphine.

Add 50 times of water to the microcapsules and spray them evenly on the canopy.

or add 5 times of water to the above-mentioned agent and mix 250 times of fine soil, and evenly sprinkle the poisonous soil under the canopy, which can achieve certain control effects. In the young fruit stage of pomegranate, the main pests and diseases that need to be controlled are hemp skin disease and cotton bollworm.

Scale insects, etc., can be used for the prevention and control of hemp skin disease in the young fruit stage. In early June of each year, it is also the germination stage of the first generation of larvae.

Pomegranate is very easy to have insects, and the pomegranate shell is very thick, it is not visible from the outside, if you want to prevent insects, first of all, the orchard must be cleaned up, not overgrown with weeds, so that there are fewer insect eggs, and then you can spray insect repellent when the pomegranate blooms to set fruit, (1) combined with winter pruning, the branches and leaves with insect pests, and the fallen fruits are removed in time for destruction. (2) During the period from the end of flowering to the expansion of the fruit, dip the absorbent cotton into trichlorfon.

1000 times the solution, stuffed into the sepal tube of the pomegranate.

Trapping and killing adults, using adult tropism, setting up black lights in the park.

Sweet and sour liquid traps to kill adults, spraying to treat insects, in the peak period of adult oviposition is timely spraying, to prevent larvae from eating fruits, the agent can be selected %20 to kill pyrethrin 2500 times, 50% phosphine 1000 times, 25% chlorpyramide 1500 to 2500 times, etc. The old method was to seal the pomegranate mouth with medicinal cotton. If it is not an old pomegranate area, there are few pests and diseases, this method is okay.

If there are more pests and diseases, then the pomegranate should be bagged and the loss will be less.

At the peak of the emergence of overwintering larvae, soil is laid or mulched under the canopy. Prevent larvae from emerging and emerging into adults. The soil was treated with chemicals, and 25% parathion microcapsules or phosphine microcapsules were evenly sprayed under the canopy with water 50 times.

Before the larvae emerge, fruit bagging is carried out in May to reduce their damage.

At this time, what should be done is to spray a large number of pesticides, so that it can be cleaned up in time in this area, and will not cause too much damage to itself, and can also avoid a decline in production.

After the guava is planted, there are insects in it, in fact, we should kill the insects when he grows to avoid the causes of insects in it, and we can also find out the reasons for the topography to avoid the effect of insects in it.

Choose different propagation methods, and the time to propagate seedlings is also different. If sowing is chosen, it is generally carried out in March. If the rhizome is selected for propagation, it is generally chosen to be carried out in November.

1. Artificial insect control method. In the early stage of insect occurrence, artificial insect control is adopted, and the aphids are brushed off with brushes and brushes and buried in the potting soil.

2. Plant insect repellent method. The smell of leeks has a repellent effect on aphids, and planting them with flowers can reduce the number and damage of insects.

3. Pepper insect control method. After boiling with fresh chili pepper or dried red chili pepper with water, spraying the affected plants with its filtrate has a special effect.

4. Washing powder insect prevention method. After adding water to the laundry detergent and stirring it into a solution, spray it several times in a row, and use it as a selective laundry detergent.

5. Wind oil essence insect control method. Spray the pests carefully with a sprayer of wind oil essence and water, so that the insect body is stained with medicine, and the effect of killing aphids and scale insects and other pests is very good, and it will not cause pesticide damage to the plants.

6. Yellow plate trapping and insect control method. Use a piece of cardboard or wood, paste yellow paper on it, and then apply a layer of butter on the yellow paper to make a booby trap board, insert the booby trap board between the flower pots, and use the aphid's yellow tropism to stick the insects to the booby trap board to achieve the purpose of eliminating insects.

7. Urine lotion mixture insect control method. Take an appropriate amount of water, add a little laundry detergent and urea, prepare a urine lotion mixture, spray it on the flowers with a small sprayer, spray it for a few days, and effectively control insects.

Many people who live in rural areas plant a few trees in their yards or in front of their houses, and even grow pomegranates in large quantities, which is also very economical. However, in the process of picking pomegranates, it is common to find that many insects seriously affect our appetite, and for large growers, seriously affect the yield and quality. So, how do you ** these pests?

Let me explain it to you.

During the flower bud period of pomegranate trees in spring, pomegranate trees are most prone to aphids, horses and other pests, and 33% of the water can remove chlorine emulsifiable concentrate or spray into mite humidification powder.

The main pests and diseases that need to be prevented in the oilfruit stage of pomegranate are horseskin disease, cotton bollworm, scale insects, etc., and 25% Seke emulsifiable concentrate can be used for the prevention of horseskin disease in the oilfruit stage. The first generation of larvae is also germinated in early June every year, but the entire tree can be sprayed with pesticides such as Fuling.

Spodoptera exigua: Dig for overwintering pupae around the trunk before the leaves sprout.

Spraying 90% trichlorfon solution and 50% new butter solution during larval occurrence can be effectively prevented. Yellow thorn moth prevention method: winter combined with winter scissors cut the advice value.

During the larval concentration period, the orchard is inspected, and the leaves are removed to eliminate the larvae. In the larval occurrence stage, 90% of trichlorfon, 50% of infrared drugs, and liquid medicine have good preventive effects.

In the adult stage, 50% of the insecticidal pine emulsion solution was sprayed, and after the injection in the field, the 5-day insecticidal rate reached more than 90%. Spraying 50% neo-yellow phosphorus or 90% trichlorfon solution 1 2 times during the hatching period of the first generation of eggs and larvae has a good effect.

Pomegranates are prone to insects, and the pomegranate skin is thick and invisible from the outside. To prevent bugs, you can first remove the orchard, lay fewer eggs to avoid overgrowing, and spray insect repellent when the pomegranate blooms. Pruning dry and bad branches in winter will do.

The old method used to be to seal the mouth of a pomegranate with cotton. If it is not the old area of the pomegranate, there are few pests and diseases, this method is okay. If there are more pests and diseases, it is necessary to give pomegranate cloth bags to reduce losses.

Because pomegranate trees themselves are prone to insects, especially during the flower bud and fruit setting periods of pomegranate trees, insect infestations are most likely to occur. At this time, it is necessary to spray the relevant pest medicine in time.

Because the pomegranate tree is not sprayed with pesticides for a long time, the pomegranate tree itself attracts all kinds of pests, and if you don't spray pesticides for a long time, there will be a lot of pests.

Pomegranate tree insects are mainly caused by rot and are mostly diseases caused by fungi. There is no way to do it if there are already worms in the guava fruit, and it is recommended not to eat guava with long worms. When the fruit grows, the method of bagging can better prevent flying insects from flying to the fruit to lay eggs and form small worms to enter the fruit.

If it is troublesome, apply the medicine when it is flowering.

Pomegranate insects are divided into two damage stages: seedling aphid and panicle aphid, and the strategy of "picking and treating seedling aphid and main ear aphid" should be adopted. When the number of 100 aphids in the field reaches 500 and the benefit-harm ratio is greater than 1 500;

50 ml of 25% aphid mite clear emulsifiable concentrate per mu, or 1500-2000 times of imidacloprid series products, 60-70 grams of 10% aphid lice; 20% imidacloprid 2500 times; 25% anti-aphid 3000 times liquid spray control.

The wheat area where wheat aphid is resistant to imidacloprid and acetamiprid should not be used alone, and can be reasonably mixed and sprayed with low-toxicity organophosphorus pesticides.

Insects growing on pomegranate trees need to be sprayed with corresponding insecticides according to the type of pests.

The most common is aphids, which can be sprayed with laundry detergent mixed with water, and other pests are mostly killed with cypermethrin. It should be noted that during the flowering period of the plant, it must not be used to remove insects, otherwise it will lead to flower drop, affect the subsequent fruit set, and can be manually captured or controlled by biological control.

To prevent pomegranate tree diseases and insect pests, pay attention to pruning in summer, keep the environment ventilated and transparent, can reduce the occurrence of pests and diseases, after fruit set, the main diseases are white rot, black pox, anthracnose, you can use the same amount of Bordeaux liquid, spray once every half a month or so, can prevent the occurrence of a variety of diseases.
