What should I do if the fortune tree has no leaves because of the insects

1. Scale insects.

1. If the liquor is mixed with water for scale insects, the liquor and water can be prepared in a ratio of 1:2, and then poured on the potting soil. This insect is most active in spring when the room temperature is 7 degrees Celsius, so you can water it once in April, and then again every half a month, and you can see the effect 4 times in a row.

2. Vinegar. To control this kind of insect, you can also use a small cotton ball dipped in vinegar and apply it to the damaged stems and leaves, which will kill the insect. This method is not only safe and convenient, but also plays a role in removing insects, so that the damaged leaves can regain their luster as soon as possible.

3. Alcohol. Repeatedly wiping the lesion with alcohol can effectively get rid of this bug, and it is also cleanly treated. Even scale insects that cannot be detected by the naked eye will be eliminated, and they will not be ** in the second year.

2. Red spiders.

If it is a red spider, it needs to be sprayed directly with special drugs for prevention, and it should be sprayed as many times as possible when spraying, otherwise it will not have the effect of prevention and control.

3. Moth and butterfly larvae.

If it's these two kinds of bugs, it's even better, just catch them with your hands.

Fourth, post-maintenance.

In order to prevent the recurrence of bugs, we need to do a good job of usual maintenance, such as reducing watering when the temperature is high, because bugs are most likely to produce when the temperature is high. Then keep it in a low-light place for 2 to 4 weeks, and then move it back to a high-light place. There are several kinds of insects in the fortune tree:

Scale insects, larvae of several types of butterflies and moths, spider mite, etc.

1. For scale insects. You can use 50 ml of vinegar, put a small cotton ball into the vinegar and soak it, and gently rub it on the stems and leaves of the affected flowers and trees with a wet cotton ball, and you can wipe off the scale insects to kill. This method is convenient and safe, which can not only achieve the purpose of insect removal, but also make the damaged leaves green and bright again.

2. For the larvae of moths and butterflies. If you're brave enough, you can catch it and kill it.

3. For spider mites. To spray, such as: you can spray 20% dicofol EC 500 600 times, 20% mesolil EC 2000 times, 5% Nisolan EC 1500 times, 50% monocrotophos EC 1500 times, etc.

Cut off the twig from the trunk and wait for it to sprout.

It's a scale insect infestation.

Scale insects are a general term for insects of the order Hemiptera, the family Scales. According to ScaleNet (2014), more than 7500 scale species have been described [1]. 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.

Depending on the occurrence of scale insects, spray at the peak of nymphs. Therefore, most nymphs hatch for a short time, the body surface has not yet secreted wax, and the shell has not yet formed, and it is still easy to kill with medication. Spray once every 7-10 days, 2-3 times in a row.

It can be sprayed with 40% dimethoate 1000 times, or 50% malathion 1500 times, or 255 imithion 1000 times, or 50% dichlorvos 1000 times, or deltamethrin 3000 times. Protection and utilization of natural enemies: such as the Australian ladybug, the big red ladybug, the parasitic shield scale, the golden aphid wasp, the soft scale aphid wasp, the red-spotted ladybird, etc., are all effective natural enemies, which can be used to control the harm of scale insects, and should be reasonably protected and utilized.

When the occurrence of scale insects is large and the damage is serious, pesticide control is still a necessary means. In winter, you can spray 1 time 10 times of pine resin mixture or 40 50 times of engine oil emulsion to eliminate overwintering females, or before germination in winter and spring, spray Baumé 3 "- 5o stone sulfur mixture or 3% - 5% diesel emulsion to eliminate overwintering nymphs; In the peak stage of nymph hatching, 1000-1500 times of insecticide mixed with 40% oxidized dimethoate EC, 40% quick-culling EC or Lesben EC and 80% dichlorvos EC in a ratio of 1:l, sprayed 3 times in a row, alternately, all have good effects.

The insect pests of the fortune tree mainly include cane flat moth, scale worm, red spider and root rot nematode, etc., when the leaf of the fortune tree is infestation, the type of insect pest should be determined according to the specific symptoms, and targeted measures should be taken to deal with the medicine.

Dear I am working on the answer to this question, please be patient.

The insect pests of the fortune tree mainly include cane flat moth, scale worm, red spider and root rot nematode, etc., when the leaf of the fortune tree is infestation, the type of insect pest should be determined according to the specific symptoms, and targeted measures should be taken to deal with the medicine.

What insect bites out the holes of the young leaves of the fortune tree?

Spraying some insecticide will do.

What pesticides?

It's the kind that is commonly used in the market.

Let's be clear, okay?

Benzoylurea insecticides.

If the fortune tree dies, will there be insects at the roots?

Fortune trees grow insects, and if the environment provided during the maintenance period is not suitable, they will suffer from insect infestations, common insect pests such as scale insects and red spiders. No matter what kind of insect pest in Jianju Mountain, once found, it is necessary to spray pesticides as soon as possible to avoid aggravation of insect pests and harm to plant growth. Answer: The number of blind insect infestations is small, just spray homemade insecticide.

If the number of insect pests is large, spraying pesticides should be used to control them. In addition, it is necessary to change the environment in which you live. Be sure to strengthen ventilation and control temperature and humidity.

When breeding the fortune tree at home, if there is a pest, causing the fortune tree to get sick, you can use white vinegar mixed with water to kill insects, you can also use vinegar to kill insects, vinegar to kill insects, vinegar can also make the eroded place, so as to restore the brilliance, you can also use alcohol to kill insects.

1. Mix liquor with water

In the process of breeding the fortune tree, the fortune tree is most susceptible to the erosion of the wide shell worm, when the scale insect patronizes the fortune tree, especially in the spring is the most frequent, you can use liquor and water according to the ratio of 1:2 to mix, and then water it into the soil of the fortune tree, and then water it again after half a month, and water it 4 times in a row to eliminate the erosion of the scale worm.

2. Vinegar.

You can use vinegar to get rid of scale insects, you can dip a cotton swab in vinegar and then apply it to the damaged area of the fortune tree, which can not only eliminate the pest, but also allow the injured leaves to return to their previous state as soon as possible.

3. Alcohol.

You can also use alcohol to repeatedly wipe the damaged parts of the fortune tree, which can not only achieve the purpose of respecting the insect removal, but also disinfect the fortune tree to prevent the breeding of bacteria, and also make the fortune tree not produce scale insects, so that the fortune tree itself is harmed.

4. Insecticides

At the same time, if the scale insects on the fortune tree are not very serious, the insect leaves can be removed first, and then placed in a ventilated environment, so as to do a good job of light and fertilization measures, if serious, you can use 40% dimethoate emulsion 600 800 times liquid to kill insects.

<> if the fortune tree is insecticidal, it is necessary to prescribe the right medicine according to different pests and kill them in time. The occurrence of scale insects needs to be sprayed with dimethoate emulsion, and the control of red spiders is to use pine borer emulsifiable concentrate. If a moth larvae are infestation, a small cotton ball dipped in vinegar or alcohol can be used to wipe the injured stems and leaves.

Fortune trees often have a scale insect infestation, which mainly sucks the sap on the leaves, resulting in the phenomenon of yellowing and shriveling, and in severe cases, it will also lead to the death of the plant. Therefore, in the event of insect infestation, 40% dimethoate emulsion 600 800 times can be sprayed to kill.

Fortune trees often suffer from red spider infestation, which sucks the sap in the branches and leaves, resulting in the destruction of chlorophyll and the phenomenon of leaf wilting and falling off. Therefore, when the red spider insect knows how to take the damage, the lack of insect leaves can be removed, and 1000 times of 50% pine moth emulsifiable concentrate can be sprayed to kill.

Some moth larvae often occur in the fortune tree, which can be dipped in vinegar with a small cotton ball and applied to the damaged stems and leaves to kill the insects. In addition, you can also use alcohol to remove the insect infestation, so that the injured leaves can regain their luster as soon as possible.
