What to do if jasmine has small bugs, jasmine buds have bugs in them

A complete guide to jasmine pest and disease solutions:

Found potted jasmine infected with aphids or whiteflies, basically will use imidacloprid, which is a necessary insecticide for flower friends, basically spraying once can remove the insect pest, when spraying, pay attention to the leaf surface, leaf back spraying evenly, to spray the whole plant evenly, the soil should also be sprayed some. Both aphids and whiteflies suck up the sap of the plant, causing the leaves to turn yellow and the plant to become worse and worse.

Thrips are usually the scourge of jasmine buds, stamens and young leaves, which will cause the leaves to curl up and wrinkle, and the leaves will grow deformed, and the flowers cannot be fully opened, the flowers will be deformed and withered early, which not only affects the ornamentation, but also affects the young leaf shoots, thrips are generally active at night, so spraying the agent should be sprayed in the evening or night, the effect is the best. If potted jasmine is accidentally infected with thrips, you can use thiamethoxam, dinotefuran or imidacloprid and spray it every 7 to 10 days, two or three times in a row. The way to physically remove insects is to hang some blue sticky insect boards next to them.

If you notice some pinhole-sized yellow spots on the back of the jasmine leaves, and the leaves gradually wither, and the leaves become very dirty, it is usually infected with red spiders.

The environment induced by red spiders is poor ventilation, dry air, and a stuffy environment, which are the main causes of the outbreak of red spiders.

If the potted jasmine has been infected with red spiders, you can cut off some branches and leaves with particularly serious insect infestation, and place the jasmine in a well-ventilated and sunny position, if the temperature can reach more than 20 degrees, and the weather is relatively clear, you can spray some mist water leaves on the back of the leaves of jasmine every morning or morning to ensure that the leaves can dry quickly, which can improve air humidity, and the environment is not suitable for the survival of red spiders, and they will naturally die.

After jasmine grows insects during the growth period, it is necessary to prune the insect leaves in time and burn them intensively to cut off the source of infection. After pruning the insect leaves, you can spray a fungicidal solution to remove insects, or you can spray pesticides to remove insects.

If there are fewer insects on the jasmine, you can spray the jasmine with a solution such as chili pepper water, vinegar water, garlic water or pepper water to get rid of the insects.

If there are more insects on the jasmine, you can spray the jasmine with insect forest or dimethoate and other insecticides. If you use a homemade sterilization solution to remove insects, you can generally spray once in 5 7 days, and after spraying 2 or 3 times in a row, you can get rid of pests. If it is to control insects with pesticides, it can be sprayed once in 7 10 days, and after spraying 3 or 4 times in a row, pests can be removed.

If there are a lot of insects on the jasmine flowers, there are also many pests in the potting soil, and the potting soil needs to be replaced for the jasmine. Remove the jasmine from the pot, trim the roots appropriately, soak them in a bactericidal solution and let them dry. After drying, the jasmine can be transplanted into new, loose, breathable soil.

Jasmine buds eaten by pests? Hurry up and treat the insects like this, so as not to hurt the buds, and the flowers will bloom smoothly.

[Double-striped whisker borer].

It belongs to the Moth family and the subfamily Divergence borer, which is known to occur in low mountains and flatlands in May and June and August September in Japan, and is the flower and fruit of the pest rodent. It is found to be harmful jasmine in China, commonly known as jasmine bud borer. The crowd called the flower drill worm.

Habits. The larvae overwinter on the young shoots and residual flowers of jasmine. At the end of February and the beginning of March, the spring warms the pupae, feathers, the adults lay eggs on the buds or young buds and young leaves, the larvae hatch into the flowers and eat the flowers, when there are no flowers, they are harmful to the leaves between the leaves, and can be transferred to the pest, and the larvae can also be harmful to the young branches, which occur more than ten generations a year. It has been observed that the insect is infested throughout the entire flowering period of jasmine, with overlapping generations, with the peak of the infestation occurring from June to September.

Prevention and control methods This insect is the main pest is flowers, and jasmine is the raw material for making flower tea, the safety requirements are particularly high, in the prevention and control, first of all, we should pay attention to not use high toxicity and high residue pesticides during the flowering period, we should try to avoid the flowering period of medication, and control the insect population density through the prevention and control before and after the flowering period. Here's how:

1) Clean the garden in winter, thoroughly cut off dead branches, insect wounded branches and insect branches, and burn them intensively. Sweep up dead leaves, or burn or bury them. To inspect the fields with a large number of overwintering insects, the application of pesticides can be combined to reduce the number of overwintering insect sources.

2) Attention should be paid to inspection during the flowering period, and all damaged flower buds, flowers and branches should be removed in time.

3) Smoke is used in the flower field at dusk to prevent adult insects from laying eggs.

4) Pharmaceutical prevention and control. You can choose 2000 times of multi-insect mites or 2000 times dilution of insect mite, or 800 1000 times of Sanle insecticide, or other avermectin pesticides, such as: 2000 3000 times of Aifudin, 2500 3500 times of 1% insect mite light, 2000 times of zitogenol, or 2500 3000 times of tea cicada clear, or 2000 times of Nonghaha, and 3000 times of cypermethrin can also be sprayed.

First, the method of insecticide.

1.Whitefly: This insect is relatively small and difficult to detect during the conservation period.

Most of them are judged based on the poor performance of the plants. When infested by whiteflies, nutrients are lost in plant leaves, resulting in wilting. The most effective way to control the insect is to spray insect chitinase to kill the insects.

2.Spider mites: This is a pest that tends to occur.

High temperatures and humidity are more frequent. When it happens, the leaves turn white and yellow. If not addressed soon, the plant will wither.

After discovery, spray with the relevant medicine cherry blossom as soon as possible. It is better to buy dicofol emulsifiable concentrate spray. Once in a while, the effect is not great, and you need to insist on taking the drug about 3 times.

2. Preventive methods.

During the breeding period, it is necessary to master the correct maintenance methods. If the breeding environment is not ventilated, the plants are susceptible to pests and diseases. Once there is an adverse performance, it is necessary to determine what kind of pest and disease it is as soon as possible, and then purchase the corresponding drugs for control.

Wipe off pests: Jasmine has bugs, so use a paper towel to wipe off the pests on the leaves. Spraying agent:

Spray dimethoate or imidacloprid once a week. Biological control: release ladybugs, thrips and other natural enemies around the seedlings.

Pruning treatment: Cut off the branches and leaves of jasmine that are seriously infected to avoid infection.

1. Wipe off pests

Jasmine has insects, you need to use a paper towel dipped in alcohol, toothbrush or brush to wipe off all the pests on the leaves of the plant to avoid serious conditions, and to put dish soap and washing powder into the water to mix, and then spray the jasmine solution to eliminate the pests.

2. Spray the agent

If you want to get rid of jasmine pests, you need to spray once a week, you can choose dimethoate or imidacloprid to maintain the normal growth of jasmine, and move the plant to a ventilated scattered light place to reduce the content of germs in the air, so as to avoid jasmine reinfection.

3. Biological control

When cultivating jasmine, it is necessary to release the natural enemies of pests such as ladybugs and thrips around the plant to prey on pests, and place insect trap lamps near jasmine to use the phototaxis of pests, and wait until night to turn on the lights to kill the pests hiding in jasmine centimeters.

4. Pruning treatment

If there are insects in jasmine, it is necessary to use sterilized sharp scissors to cut off all the branches and leaves of the plant that are seriously infected to avoid infection, and spray carbendazim or potassium permanganate solution to the fracture of the jasmine to avoid its wound from being infected by the disease and rotting.

Pruning insect leaves: pruning insect leaves and carrying out centralized incineration treatment to stop the source of infection from the root; Spraying drugs: use dimethoate to remove insects, spray once every 7 10 days, spray 3 4 times continuously; Replacement of soil:

Replace the potted plants with new soil and disinfect the pots; Ventilation culture: The replanted jasmine flowers are placed in a cool and ventilated place for a week, and then moved to a light and well-ventilated environment.

After jasmine peanut insects, it is necessary to prune the insect leaves in time and carry out centralized treatment, and it is recommended to use incineration to effectively eliminate the insect pest and stop the source of infection from the root. After the pruning of insect leaves, it is necessary to continue to observe the branches and leaves, and if you find small round spots, it is recommended to prune off the branches to prevent insect pests**.

When there are fewer bugs, you can soak a cigarette in water overnight and then spray it on the branches and leaves of the bugs and jasmine with a watering can. If there are more insects on the jasmine, it is recommended to use dimethoate insecticide, spray it on the branches and leaves every 7 to 10 days, and spray it 3 or 4 times in a row to remove it.

To avoid insect infestation due to residual eggs in the soil**, it is recommended to replace the jasmine pots with new soil and disinfect the pots. It is recommended to replace the soil with humus, pastoral soil, and silt soil according to 4:3

3 proportions of the preparation of planting. Before planting, the roots of jasmine can be properly pruned, and all blackened and rotten roots can be pruned off.

After pouring the replanted jasmine flowers with an appropriate amount of water, they are placed in a cool and ventilated place for about a week to allow them to slowly adapt to the new growth environment. After a week, it will be moved to an environment with sufficient astigmatism and good ventilation conditions to maintain it, so that the jasmine plants can fully receive sunlight and oxygen, and promote good growth and development.

1. Pour flour and whole milk powder into a container, add water and stir well, then filter with gauze, and spray the filtrate on the flowers and leaves to eliminate insects.

2. Put a cigarette in a spray bottle, soak it overnight, and then spray it on the insects to kill the insects.

3. Chop the garlic, put it in a spray bottle, add water, and spray it on the insects to eliminate it.

How to raise jasmine.

1. Proper watering is the key to how to raise jasmine, in spring and autumn jasmine does not require much water, only need to be watered once every 2 3 days.

In the case of high temperature in summer, it needs to be watered twice a day to meet its water demand, and in winter, it needs to be watered once every 5 to 7 days to avoid water accumulation.

2. As a sun-loving flower, jasmine should be placed in the sun when maintaining it, so that it can receive sufficient sunlight to better photosynthesize, so as to grow more vigorously.

However, it should be noted that the strong light in midsummer will sunburn the jasmine, so it is necessary to shade and protect from the sun in time.

3. Phased fertilization of jasmine requires continuous topdressing to supplement nutrients in maintenance, but the fertilizer required at different growth stages is different.

Generally, at the seedling stage before the flowering, it is necessary to apply an appropriate amount of nitrogen fertilizer to make the leaves flourish, and at the time of flowering, it is necessary to apply organic fertilizer to make the flowering period longer and the flowers more colorful.

However, after flowering, it is necessary to cut off the stumps of the flowers, and the sick and old stumps should be removed in normal times, so that the nutrients of jasmine are not wasted.
