It may be a whitefly infestation, and the nymphs resemble scale insects, flattened and oval, and are often covered with a cotton-like substance. This is small and can be gently brushed off with a soft brush.

The white cotton wool on the branches of gardenia flowers may be scale insects. Gardenia is prone to scale insect damage and is accompanied by soot disease when the ventilation is poor and the temperature and humidity are too high. For scale insects, bamboo skewers can be used to scrape off, and No. 20 petroleum emulsion can also be sprayed with 200 times water.

For soot disease, it can be scrubbed with water, or sprayed with carbendazim 1000 times for prevention and control.

This can be a whitefly infestation, nymphs like scale insects, flattened oval, and are often covered with a cotton-like substance. This is small and can be gently brushed off with a soft brush.

The white worms on the gardenia you are talking about should be called scale worms, because they often clump together and the secretions are white powdery, so they look like white bugs. The insect mainly feeds on the juice of gardenias, which is very harmful to the growth of gardenias.

If you want to talk about how to treat, it is actually very simple, divided into physical elimination method and drug elimination method, the specific way is as follows:

1. Physical extermination.

It's very simple, you just use a toothbrush or a stick or something like to get rid of the bugs and run them over. But this method requires you to have enough patience and time, which is relatively time-consuming.

2. Timely pruning, pruning dense places to ensure ventilation and light transmission, and reduce the possibility of scale insect growth.

3. Completely burn the removed branches and insect sources to directly cut off the source of infection.

The pests that harm gardenia are aphids, jumping beetles and moth larvae, the first two can be dimethoate and trichlorfon, and the latter can be controlled or manually caught by 666 powder.

Gardenia pest control. In addition, when the indoor ventilation and temperature and humidity are too high in winter, gardenia is prone to scale insect damage and is accompanied by soot disease. Scale insects can be scraped off with bamboo skewers or small brushes, and can also be sprayed with No. 20 petroleum emulsion and 100 150 times water.

Soot disease can be scrubbed with water, or sprayed with carbendazim 1000 times for prevention and control.

Cultivation technology: 1. The demand for soil.

Gardenias like to grow in an acidic soil environment, so when purchasing gardenia soil, pay attention to the selection of acidic soil for breeding, and pay attention to the soil pH value control between appropriate, so the choice of soil is also very important for the needs of breeding.

2. Suitable growth temperature requirements.

According to the needs of the growth temperature of gardenias, the optimal growth temperature is 16 -18 is the best, but it should be noted that the temperature is too high or too low is not conducive to the growth needs of gardenias, so it is recommended to choose a well-ventilated indoor breeding in summer and winter, so this is also important for farmers.

3. Sufficient moisture.

Gardenia is like a warm, humid and sunny environment, so the demand for water and the humidity of the air is also very important, during the growth of gardenia, we should pay attention to the appropriate amount of watering, but also pay attention to the gardenia foliar spray some water, can improve the humidity of the air, but also pay attention to the winter watering should not be too much, to prevent the occurrence of rotten roots.

4. Sufficient light time.

Gardenia during the growth period, but also pay attention to the need for the right amount of light, gardenia is a plant that loves light, so it is recommended to pay more attention to increasing the light time during the spring and autumn period, and in the summer and winter, it is recommended to put it into the same indoor breeding with light to avoid the growth period, the temperature is too high or too low.

5. Appropriate amount of fertilization and replenishment of nutrients needed for growth.

Gardenia's demand for nutrients is also very high, in order to meet the gardenia's demand for fertilizer during the growth period, it is recommended to apply fertilizer such as soybean cake, sesame sauce residue, peanut bran and other fertilizers every half a month during the vigorous growth period of gardenia, which is also conducive to the blooming of many and vigorous flowers.

6. Pay attention to pruning.

During the growth period of gardenias, the branches are easy to overlap and are not ventilated, so during this period, an appropriate amount of pruning can also promote growth and prune other branches that sprout from the root tillers.

Use a high-efficiency and low-toxicity insecticide diluent solution to kill it by brushing it with a brush.

Spray a slightly toxic insecticide, or cut off the leaves that have insects, do not place them in a dark place, and if there are too many eggs, put some beneficial insects.

Gardenias are prone to scale insects and soot disease in the case of poor ventilation and high temperature and humidity, so pay attention to it.

Don't worry about the return wind.

Answer: Gardenias are placed in a high humidity environment, if you can't distinguish the species of pests, you can spray the florist's parafen, which can generally kill the pests of gardenias.

If you want to prevent insects, you can strengthen ventilation conditions and promote air circulation, which can effectively prevent insects.

Bring sick leaves and ask — under the sale of pesticides, and then buy medicines, to kill insects.

1. Spraying: Gardenia When there are white insects, you need to use a wet paper towel to wipe off the insects, and then spray special insect killers. 2. Ventilation:

Move gardenias to a ventilated semi-shaded environment to reduce the chance of infection of the plant. 3. Humidity: Wait for the soil surface to dry before watering to promote the healthy growth of gardenias.

1. Remove bugs

Gardenia has small white insects, which will endanger the health of the plant, we can wipe off the insects and eggs with water, and then use trichlorfon, chlorchlorine, dimethoate EC and other insecticides to spray the plant according to the method of use, so as to completely prevent it from producing insects.

2. Ventilation environment

Gardenias are easy to grow white insects in a poorly ventilated environment, especially in winter when the indoor ventilation is poor, so when maintaining gardenias daily, we need to do a good job of ventilation management for them, and we also need to ventilate them while keeping warm in winter, so as to avoid it from growing white insects.

3. Suitable humidity

In the environment of high temperature and high humidity, gardenias are also easy to grow small white insects, so when maintaining gardenias in summer, it is necessary to take temperature control measures for them, and it is best to maintain them in a cool place.

Gardenia After the small white bugs grow, we can wipe off the bugs and eggs with clean water, and then spray them with a special drug**. In winter, if the indoor ventilation is poor, it is easy to grow small white insects, so in winter, it is necessary to do a good job of ventilation management while keeping it warm, and it should also be cooled in time in hot weather.

This is an aphid. Aphids, also known as honey worms, greasy insects, etc., mostly belong to the homoptera aphid family, are pests of stinging and sucking mouthparts, often clustered in leaves, young stems, flower buds, top buds and other parts, sucking sap, so that the leaves shrink, curl, deformed, in severe cases, cause branches and leaves to wither and even die of the whole plant. The honeydow secreted by aphids can also induce coal stain disease, viral diseases and attract ant damage.

Insecticides can be made homemade, take soap and hot boiled water according to 1:50 dissolution and spray Shi Qiaomo, because soap can block the respiratory organs of pests to their death, effective for aphids and scale insects. You can also take 50 grams of green onions and mash them into a puree, add 50 grams of water, soak them for 12 hours, spray them with filtrate after filtration, spray them many times a day, spray them for 3 or 4 days, and treat soft pests such as aphids and powdery mildew.
