Pest control. Gardenias are often susceptible to yellowing of leaves, which is caused by a variety of reasons, so different measures must be taken to prevent and control them. Yellowing caused by lack of fertilizer:
This yellowing disease starts from the lower old leaves of the plant and gradually spreads to the new leaves. Nitrogen deficiency: simple leaf yellow, new leaves small and brittle.
Potassium deficiency: The old leaves turn green to brown. Phosphorus deficiency:
The old leaves are purplish-red or dark red. In all cases, you can be forced to apply rotten human feces or cake fertilizer. Yellowing caused by iron deficiency:
This yellowing disease, manifested on new leaves, begins with pale yellow or white leaves, the veins are still green, and in severe cases, the veins are also yellow or white, and eventually the leaves will dry up and die. In this case, the aqueous solution of ferrous sulfate that can be sprayed can be prevented. Yellowing caused by magnesium deficiency:
This yellowing disease begins to develop from old leaves to new leaves, and the leaf veins are still green, and the leaves fall off and die when they are severe. In this case, boron and magnesium fertilizer can be sprayed to prevent and control. Excessive watering, freezing, etc., can also cause yellow leaves, so special attention should be paid during the maintenance process.
Gardenia is prone to scale insect damage and is accompanied by soot disease when the indoor ventilation is poor and the temperature and humidity are too high in winter. 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.
The pests that are harmful to gardenias are aphids, jumping beetles and moth larvae, the first two can be dimethoate, trichlorfon, and the latter can be controlled or manually captured by 666 powder.
Gardenia pest control.
1) Pest infestation. Gardenia is susceptible to scale insects in a high humidity and poorly ventilated environment, which can be removed with a small brush or sprayed with 100 150 times No. 20 gasoline emulsion.
2) Disease. Sooty disease: occurs on branches and leaves, can be scrubbed with water after discovery, or sprayed with 0 3 Baumé stone sulfur mixture, 1000 1200 times carbendazim.
Rot disease: often occurs on the lower trunk, the stalk swells, cracking, scraped or coated with 5 10 degrees of stone sulfur mixture immediately after discovery, several times to be effective.
Leaf spot and yellowing often occur in pests and diseases, and leaf spot is sprayed with 65% zebsen wettable powder 600 times, and ferrous sulfate solution is added to the watering regularly to prevent and control yellowing. Insect pests are stinging moths, scale insects and whiteflies, spray stinging moths with 3000 times of emulsifiable concentrate and spray 1500 times of dimethoate emulsifiable concentrate with 40% dimethoate and whiteflies.

Gardenias are easy to attract insects? Don't worry, it's easy to do it in 2 ways.
-
You can spray permethrin, dichlorvos, and dimethoate.

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. Drug Eradication Act.
80% dichlorvos is sprayed according to the ratio of 1000 times the liquid (1000 times the liquid is the ratio of 1 gram of dichlorvos to 1000 grams of water), which is trouble-free and worry-free, and it is also the most commonly used method. However, please pay attention to safety during the medication process, remember to wash your hands, and do not let children touch them.
In addition to being effective, we should pay more attention to prevention, and I will give you a few ways to make an appointment below.
First, it is necessary to apply fertilizer regularly, so as to achieve the principle of thin fertilizer and more fertilizer, that is, the fertilizer should not be too fat and too thick. This strengthens the resistance of gardenias.
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.

Gardenia peanut has white bugs, possibly chaffron and blown cottonworms. During the maintenance period, the leaves of the gardenia need to be cut off and burned intensively, and then sprayed with insecticides such as imidacloprid or dimethoate. The agent can be sprayed 1 time for about 7 days, do not stop halfway, spray 2 or 3 times in a row to get rid of pests, and the gardenia can be recovered in the later stage.
After gardenia induces insect infestation during the growth period, common white pests are chaff and blown-cotton. Pityriasis and cottonworms can endanger the young leaves of gardenias and affect the growth of gardenias. If the gardenia is infested by the chaff and the cotton-blown insect, the branches and leaves need to be cut off in time and burned in a concentrated manner to avoid the reproduction of the eggs.
After pruning the leaves of the gardenia, the gardenia can be sprayed with imidacloprid, dimethoate or dimethoate for insect control. The back of the pityriasis and the pityriass has a layer of wax that is not easy to remove. During the spraying period, a variety of agents can be used alternately, the effect is stronger, the agent should be used consistently, and it is not recommended to stop using it halfway.
After diluting the agent with water, carefully spray the stems and leaves of the gardenia to remove pests and eggs. After spraying the gardenia, the gardenia needs to be kept in a cool and ventilated place indoors. During the spraying period, the agent can generally be used once in about 7 days, and after spraying 2 or 3 times in a row, it can remove the chaff and blown cotton-mediated insects.
In the later stage, when the gardenia recovers, it needs to be given enough light, water and fertilizer for it to grow. Sufficient light and water fertilizer can make gardenias grow better and can enhance the disease resistance of gardenias. In the later stage of maintenance, you can spray the gardenia with fungicide once every 20 days, which can effectively prevent pests and diseases.

The solution of gardenia peanut insects: maintain a suitable humidity in the environment and do not create breeding conditions for insects; Rinse with clean water to get rid of bugs; Spray with yellow tobacco leaves or leftover cigarette butts soaked in water, and the contact killing effect is obvious.
1. Gardenia, also known as gardenia, yellow gardenia, is an evergreen shrub of the order Rubiaceae, Rubiaceae, and Gardenia, native to China. It prefers warm, humid and sunny environments, is more cold-tolerant, semi-shade-tolerant, afraid of stagnant water, and requires loose, fertile and acidic sandy loam soils.
2. Gardenia fruit ovate to oblong-elliptic, with 5 9 wing-like straight ridges, 1 chamber; The seeds are abundant and are embedded in the fleshy placenta. 5-Blooming in July, flowers, leaves, and fruits are beautiful, and the flowers are fragrant. Roots, leaves, and fruits can be used as medicine for liquid or land, which has the effect of purging fire and removing troubles, clearing heat and diuresis, cooling blood and detoxifying.
3. Common insect pests of gardenias include red spiders and scale insects. At the time of the disease, the leaves of the plant will be full of holes, which will not only affect the growth of the plant, but also reduce the ornamental degree of gardenias. Spider mites mainly damage the leaves of gardenias, and spider mites parasitize gardenias, mainly feed on leaf sap, and grow on the back of leaves.
Plants infested with spider mites have yellowed leaves and weakened growth. In addition, spider mites are more fertile in high, dry and warm environments.
4. Scale insects are pests that harm gardenia branches and leaves, although they are small in size, their lethality should not be underestimated. Scale insects live by sucking the sap of plants, the light ones are yellow and fall off, the plant growth is weak, and the heavy ones are dead, which has a great impact on the growth and development of gardenias.
