What to do if the sunflower has black bugs, and the sunflower has white bugs

The appearance of black bugs on sunflowers is a common insect infestation. If there are only a few of these bugs, you can use physical methods to control them. Remove the bugs from the sunflower plants with tweezers and burn them to prevent them from reproducing and infesting the plant.

However, if the number of black bugs is high, chemical methods are needed to control the infestation. First of all, the severely infested branches and leaves need to be removed to prevent the further spread of the bugs. Then apply Baumé's stone sulfur mixture to the wound area, and spray the whole plant with a solution of 90% trichlorfon 1000 times or 40% dimethoate 2000 times solution once a week for one month.

This effectively kills bugs and helps sunflowers regain their health.

In the daily maintenance of sunflowers, the environment should be kept ventilated, overwatering should be avoided, and regular fertilization should be applied to strengthen the plant's resistance. If any insect infestation or other abnormalities are found, immediate action should be taken to avoid worsening the damage.

This is a scale worm.

Scale insects are very difficult to kill. If you want to kill scale insects, you can use chlorphosphine, which is a more commonly used medicine, but the smell is a bit loud and the smell is more pungent. Thiamethoxam.

It is also possible, and it can have a highly effective insecticidal effect.

If not more, you can use 75% alcohol, brush dipped in alcohol to brush the blades.

You can use avermectin, spirodifen, alkyne mite and other pesticides spray control, indoor maintenance, if you don't want to use pesticides, you can use dish soap and laundry detergent to mix with water, foaming is appropriate, and then brush with a soft brush, brush off the insects and then spray.

Sunflower is a purslane plant, the leaves and stems are fleshy, and it is easy to grow insects in summer, and the white bugs that often appear on sunflowers are usually mealybugs and whiteflies. Mealybug is an insect of the mealybug family, there is a layer of white and colored waxy cover on the surface, mealybug will suck the sap on the stems and leaves of the sunflower, harm the growth of the plant, and even kill the bridge pei, easy to occur in the environment of high temperature and high humidity, and the most harmful from May to June.

Mealybugs reproduce quickly, so they should be controlled in time and prevent them from spreading to other potted plants. In addition, whiteflies can grow on sunflowers.

Methods of whitefly control:

In the spring, whiteflies will occur, and 10% chlorpyrifin EC or 25% chlorpyrifin EC can be used for sensitivity control in the early stage, and a small amount of pyrethroid insecticides can be added during the nymph hatching period, sprayed once every 5 to 7 days, lasting 2 or 3 times. In severe cases, 20% methocarb EC, 10% imidacloprid wettable powder and antibiotic solution should be used regularly.

The solution to the white insects of the sunflower: use laundry detergent, wind oil essence, vinegar, mosquito coils, liquor, etc.

1. Laundry detergent

Spraying the sunflower with laundry detergent mixed with water can prevent and control this white bug, because the active substance contained in the laundry detergent is sodium alkyl benzoate, which can quickly remove the ash layer of the insect body when it comes into contact with flower insect pests, thus entering the pest's body and suffocating the insects.

2. Wind oil essence

Wind oil essence is also a good baby to kill white insects, spraying with wind oil essence can penetrate into the insect body, so that the pest is killed, the effect is very good.

3. Vinegar

Vinegar can also be a good white insect, put a small cotton ball into the vinegar and soak it, and gently rub the cotton ball drenched with vinegar on the stem and leaf with the insect to kill the insect.

4. Mosquito coils

Mosquito coils are also very effective in killing white insects, and after lighting the mosquito coils, put them on the sun flower pot with white bugs, and then cover the flower pot with a transparent plastic bag for about an hour to kill the insects.

5. Liquor

Mix some tap water with expired liquor at home, put it in a watering can, and pour a layer on the surface of a potted plant with white bugs. White insects begin to move when the indoor temperature reaches 7 degrees Celsius, so after using it once, it can be watered once every half a month, and 4 times in a row can be effective.

First, what's going on.

It tends to cause white bugs, also known as scale worms, during its growth. This is usually caused by a hot environment or if the soil is too wet. Although this pest is relatively small, it reproduces quickly and can seriously harm the growth of plants in the later stage, so it is necessary to treat it as soon as possible to avoid further deterioration.

Second, what to do.

1. Liquor mixed with water: liquor can be mixed with water when processing. There is expired liquor at home, mixed with water and put in a watering can. Spray on the surface of the potting soil layer infected with scale insects, spray once every half a month in between, and spray continuously for four seasons to eliminate it.

2. Laundry detergent mixed with water: When you first find it, you can spray it with laundry detergent with water, about 200-300 times of water. When spraying, sprinkle on the flower stems, every three to five days, until the pests are eliminated.

3. Use tweezers to tweezers: If the pests can be seen with the naked eye and the number is relatively small, it is recommended to pinch off directly with tweezers, or you can pinch off the stems and leaves of the insects. However, in the later stage of treatment with this method, it is necessary to observe diligently to avoid further infection.

4. Spraying drugs: drugs can also be sprayed during treatment. The medicine can be colein, which is generally sold in florists, and it can be diluted according to the above instructions after buying it.

When spraying, it should be sprinkled on the flower stems, and once every three or five days in the middle, and it can be eliminated after three or four times. However, if you want not to be infected in the later stage, it is recommended to change the soil, change the pot, and clean the pot.

What should I do if there are small insects in the flowers raised at home?

If there are only a few black bugs on the sunflower, you can use tweezers to pinch the bugs from the sunflower plant and then burn them. If the number of insects is large, it is necessary to remove the diseased branches and leaves, apply the baume stone sulfur mixture to the wound, and spray the whole plant with 90% trichlorfon 1000 times solution or 40% dimethoate 2000 times solution, once a week for one month.

The solution to black bugs on the sunflowers.

If there are not many black bugs on the sunflowers, and the sunflower plants do not show obvious developmental abnormalities, physical insect control methods can be used. Use tweezers to pinch the black bugs away from the sunflower plant and incinerate the black bugs so that the bugs do not move to the sunflower again.

If the quantity is large, chemical control methods are required. The branches and leaves of the sunflower plant that have been infested by insects are removed, the wound is smeared with Baumé stone sulfur mixture, and the diseased branches and leaves are burned in a centralized manner. Don't feel sorry for even the flower branches, as not removing the diseased branches will affect the health of the entire plant.

Once the diseased leaves have been removed and treated, it is time to prepare for spraying. Generally, for black insects, it is necessary to spray 1000 times solution of trichlorfon or 2000 times solution of 40% dimethoate emulsifiable concentrate on the whole plant, once every 5 to 7 days, for one month to consolidate the insecticidal effect.

After the sunflower returns to normal, it should not be taken lightly, and daily maintenance needs to take precautions to prevent the return of pests. For daily maintenance, you need to place the sunflower in a well-ventilated environment, spray some liquor on the leaf surface every week, and sprinkle some soot on the soil surface.

Generally scale insects.

Scale insects are a general term for insects of the order Hemiptera, the family Scales. According to ScaleNet (2014), more than 7500 scale insect species have been described. Most species of insects have waxy secretions on their bodies, which resemble shells, hence the name scale insects.

Scale insects are the most common pests on flowers and fruit trees, often clustering on branches, leaves, and fruits, sucking plant sap for survival, and in severe cases, they will cause branch wilting or the whole plant die. In addition, the secretion of scale insects can also induce coal stain disease, which is extremely harmful. The common ones are blown cotton scale, camphor mussel round shield scale, bran scale, Korean ball scale, mulberry white scale, Kang's mealybug, Fuso cotton mealybug and so on.

Prevention and control method: mix liquor with water, the ratio is 1:2.

When treating insects, water the surface layer of the potting soil thoroughly. Scale insects begin to move at room temperature 7 in spring. It can be watered once in April, and then once every half a month or so, 4 times in a row.

Use 50 ml of vinegar (rice vinegar), soak a small cotton ball in vinegar, and gently rub it on the stems and leaves of the affected flowers and trees with a wet cotton ball to wipe off and kill the scale insects. This method is convenient and safe, which can not only achieve the purpose of insect removal, but also make the damaged leaves green and shiny again.

Gently and repeatedly rubbing the diseased plant with alcohol can remove the scale insects, and it can be removed very cleanly and thoroughly. If you wipe the orchid leaves with alcohol, not only can you get rid of the scale insects, but also the larvae that are not clear to the naked eye, and they are completely killed.

Use diesel, washing powder, water according to the ratio of :6 to adjust the mother liquor, at this time the mother liquor contains 60%, milk-like, diluted with water 30% of the oil solution, the Milan, kumquat, cycad on the scale insects carefully sprayed. After one week, most of the scale insects changed from fresh orange to shriveled state, indicating that this method has a good control effect on the meso-combustion scale insects.
