How to deal with the long insects of potted honeysuckle, and the control of diseases and insect pests of honeysuckle (spraying insecticide)

Honeysuckle is a kind of good-smelling flower. Honeysuckle is loved by people for its unique fragrance. With the progress of pot technology, honeysuckle can also be raised at home. Any plant in nature can grow worms. Of course, honeysuckle is no exception. How to deal with honeysuckle worms? The common pests of honeysuckle are red spider, bark moth, winter round tail aphid and so on. Let's take a look at the pest control of honeysuckle.

First, how to deal with honeysuckle worms, spraying to kill insects

Speaking of honeysuckle, I believe we are not strange, honeysuckle vitality is very tenacious, but if poor care may also lead to honeysuckle pests. Earlier we talked about what to do when the leaves of honeysuckle turn yellow. Now let's take a look at how to deal with the honeysuckle worm. There are many kinds of diseases and insect pests of honeysuckle. Let's explain the solutions one by one.

II. Pest control of Flos Lonicerae

1. Red spider

This insect is one of the main pests of Flos Lonicerae, which is rare. But once it is infested by red spiders, it is a headache. The way of doing harm is to suck the juice from the leaves of flowers with mouth organs, so that the chlorophyll of flowers is destroyed, the leaves show gray-yellow spots or patches, and the leaves become withered and yellow, or even fall off.

Solution: how to deal with honeysuckle worms? When the above symptoms are found, it should be noted that if individual leaves are injured, insect leaves can be removed. When more leaves are damaged, spraying should be carried out as soon as possible. The commonly used pesticides are propargite, dicofol, dimethoate, Huachongjing, and so on.

2. coffee tiger longicorn beetle

Coffee tiger longicorn beetle is an important stem-boring pest of Flos Lonicerae. It is mainly distributed in the old producing areas of Honeysuckle in Shandong, especially in Pingyi and Feixian. The damage rate of the flower stump that has been investigated for more than ten years is 80%. The honeysuckle affected by this damage will grow weak, and the whole plant will die after a few years.

Solution: honeysuckle pest control in April to May adult occurrence period, and larvae first hatching stage with 80% dichlorvos emulsion 1000 times spray to control adults and newly hatched larvae have a certain effect.

3. APHIS gossypii and APHIS gossypii

This kind of disease and insect sucks the leaf juice with adults and nymphs, which makes the leaves curl and yellowing, the flower bud is killed at the bud stage, and the flower buds are deformed; honeydew is secreted in the process of damage, which leads to the occurrence of soot disease and affects the photosynthesis of leaves. In October, the insect migrated from the first host Umbelliferae to the honeysuckle to mate and lay eggs over the winter. the damage was the most serious in the first and middle of May, seriously affecting the yield and quality of honeysuckle, and generally moved back to the first host in June.

Solution: spray 1000 times of 40% dimethoate emulsion or 1000-1500 times of 80% dichlorvos emulsion once every 7 to 10 days for 2 times in a row. Do not spray at least half a month before honeysuckle picking to prevent pesticide residues on honeysuckle.

4. Leopard bark moth

After hatching, the larvae of the leopard beetle moth are eaten from the branches or new shoots. 3-5 days later, the new shoots of honeysuckle withered, and the larvae grew to 3-5 mm and excreted insect feces from the hole. At this time, it is easier to find insect pests. When the larvae bite between the xylem and phloem, the branches are easy to break in the wind, and there are often several fecal holes on one side of the damaged branch. insect feces are cylindrical and yellowish, and withered plants appear at the flower stump from September to October. The insect has the habit of transforming plants to do harm.

Solution: clean up in time, pay attention to observation, after harvesting the second crop of flowers, be sure to combine pruning from late July to early August, and cut off the insect branches. If the pruning is too late, the larvae eat into the lower coarse branches and then cut branches have an effect on the growth of the flower stump; spraying pesticides. I believe everyone knows what to do with the honeysuckle worm.

III. Prevention of diseases in Flos Lonicerae

1. Brown spot

It mainly harms the leaves, there are many yellowish-brown dots on the leaves at the beginning of the disease, and gradually expand into round or polygonal disease spots in the later stage. There is a gray-black mildew on the back of the leaves when it is wet, which is easy to break when dry, and when the disease is serious, the leaves fall off after withering and yellowing, affecting plant growth and flowering.

Prevention and control methods: pay attention to keep clean, remove diseased branches and fallen leaves in time, cut off diseased leaves at any time during the disease period, and then take them out of the garden for centralized burning. At the initial stage of the disease, you can spray with 1V 15v 200 Bordeaux liquid, or with 50% carbendazim wettable powder 1000 times, or 75% chlorothalonil wettable powder 1000 times spray, once every 7 to 10 days, 2 to 3 times in a row.

2. Rust

A kind of leaf disease that is easy to occur in high humidity, tea-brown or dark brown spots appear on the back of the leaves, some also appear near round spots on the leaf surface, and there is a small blister in the center, which can cause leaf death in a short period of time.

Control methods: in the cultivation and management, apply more phosphorus and potassium fertilizer and less chemical nitrogen fertilizer to promote the healthy growth of the plant and improve its disease resistance. Chemical control must grasp the spraying at the initial stage of the disease, and the available fungicides are 50% rust rather than 800 times of wettable powder, or 50% dinitrate powder 200 times, sprayed once every 7 to 10 days, 2 to 3 times in succession; spreading 400 times of Dysen zinc around the plant during the growing period has a better control effect. The above is the whole content of honeysuckle pest control and how to deal with potted honeysuckle worms. I hope I can help you.

How to deal with potted cactus worms, cactus pest control (spraying insecticides) 1. How to deal with potted cactus worms, spraying insecticides to kill insects

Although the cactus is very easy to raise, there will still be diseases and insects if it is not well taken care of. The diseases and insects that often appear in potted cactus are: locusts, red spiders, scale insects, and so on. Many people do not know how to deal with cactus worms. In fact, the control methods of each kind of diseases and pests are different. Let's take a look at the prevention and control methods of cactus diseases and insect pests.

II. Prevention and control of diseases and insect pests of cactus

1. White shield scale insects

Cactus white shield scale, also known as cactus scale, Homoptera, Coccidae, female shell nearly round, about 2 mm, gray-white. It occurs 2 to 3 generations a year, and occurs for many generations in a greenhouse or plastic shed, causing harm all the year round. In spring, the nymphs were concentrated on the fleshy stem after hatching from mid-January to early February. When it entered the peak incubation period from April to September, the number of insects increased rapidly, the insects were concentrated in piles, and the phenomenon of generation overlap was serious. The growth and development of the damaged plants were inhibited, and in severe cases, the succulent stems partially or completely rotted.

Solution: after the occurrence of shield scale damage in the cactus, the scale insects parasitic on the succulent stem of the cactus should be manually removed immediately, and attention should be paid to maintaining the ventilation and light transmission of the plant so as to reduce the occurrence of insect pests. Chemical control measures can be adopted to seize the favorable opportunity of nymph hatching period and weak nymph resistance, choose 40% omethoate 1000 times, or 50% fenitrothion 1000 times, or 40% fenvalerate EC 1500 times, 20% fenvalerate EC 2500 times. All the cactus plants harmed by the white shield scale can be sprayed, which can have a good control effect.

2. Red spider

Red spiders, commonly known as fire dragons, are mites. Its individual is very small, less than 1 mm long, round or oval, orange or reddish brown. We should try our best to defend against red spiders, so the cultivation environment must be ventilated and the humidity is suitable to avoid dryness and muggy heat as far as possible.

Solution: 40% omethoate 1500 times liquid and 40% dicofol 1000 times liquid. Spray for 1-2 weeks in summer, and thoroughly before overwintering.

3. Aphids

There are many kinds of aphids, usually green, yellow, black and brown. Aphids occur all the year round and reproduce most rapidly at about 29 ℃. Most of them gather on the buds, tender leaves or twigs of the plant, sucking the juice endlessly, the branches and leaves of the killed plant are yellow and deformed, the flower buds are rotten, the florescence is shortened, the flower volume is reduced, and the plant wilts and dies seriously.

Solution: bury 30% carbofuran or 30% aldicarb particles into the basin soil at a depth of 5 to 10 cm, which can be effective in 2 to 3 days (highly toxic, beware). Soak aphid cut tobacco in 20 times water for 48 hours, then add 20 times water and 10% washing powder to stir, filter residue can be used for spray killing. The washing powder, urea and water can be mixed into a mixture according to the proportion of 1:4:l00, which can be used to spray plants, which can kill insects and fertilize two birds with one stone.

4. Thrips

When thrips live in young leaves, they will die at the top, making it unable to grow. If it feeds at the back of the leaf and excrete brown substance, it will deform the back of the leaf, and gray or grayish brown stripes will appear on both sides of the midrib, deforming and bending.

Solution: this situation of cactus pest control, can be sprayed for treatment, select imidacloprid, acetamiprid, thiazide and other effective ingredients. The above is how to deal with cactus worms, do you know? Let's take a look at the disease of the cactus.

III. Disease control of cactus

1. Anthrax

Symptoms: anthracnose is an important disease of cactus flowers, is a fungal disease, which is characterized by pink sticky matter on the spot. The disease often causes stem nodes or globular stems to rot and dry, affecting the normal growth of plants. During the initial infection of the diseased plant, the local part of the flat stem appeared no obvious water-stained spot (or light brown spot), the lesion site was sunken, the edge was slightly raised, and there were small black spots in the upper part, which were slightly arranged in the shape of a wheel.

Solution: note that anthrax is spread by spores of pathogenic fungi, which are light and easy to float in the air, so it is necessary to isolate the diseased plants and cut off the diseased leaves and burn them, otherwise, it will not only be difficult for the diseased plants to recover, but also infect nearby healthy plants with anthrax.

Spray 50% methyl topiramate 600 to 1000 times every 10 days, or 75% chlorothalonil 800 times, or 1% Bordeaux solution (either of the above agents) every 10 days. In order to increase the effect of pesticide application, pot and cultivation sites should be treated at the same time of spraying.

2. Stem rot

Disease: stem rot, also known as Fusarium wilt, is a fungal disease, many varieties can be infected, cactus is easy to occur common diseases. Young cacti and grafted plants are particularly sensitive to the disease. The disease occurs in the near-ground stem, can spread upward gradually, and can also occur in the upper stem node.

Solution: immediately remove the diseased tissue from the diseased plant, smear and disinfect the incision with sulfur powder or charcoal powder, at the same time, control watering, change the basin, eliminate the disease root, and disinfect the soil with 20% lime milk or 50 to 100 grams of bleach per square meter. At the initial stage of the disease, the base of the plant was sprayed with Bordeaux solution or 4000 times of agricultural streptomycin, once every half month, for 2 to 3 times. The above are the solutions to the prevention and control of cactus diseases and insect pests. Have you learned? The answer to how to deal with cactus worms hope to help you.

What about the growing insects of potted camellias? disease and pest control of camellias (spraying insecticides)

With the progress of pot technology, camellia has become a scenic spot in many people's homes. Insects can grow in any plant, and camellia is no exception. What about the camellia worms? Camellia common pests are aphids, stem borer, red spiders, for each different insect, its control methods are not the same, let's take a look at camellia pest control.

What about the camellia worms? spray to kill the insects.

Camellia is very common in life, and its unique flowers and fragrance are loved by people. Earlier, we talked about how to raise camellias, the efficacy and function of camellias. Now let's talk about one of the most common problems: what to do with camellias and the prevention and control of diseases and insect pests of camellias. There are many common pests in camellias, and each method of prevention and control is also different. Let's explain one by one below.

II. Control of diseases and insect pests of camellia

1. Aphids

Aphids are divided into winged aphids and wingless aphids. Aphids will cluster on the tender shoots of camellias to absorb juice, which will shrink the bud leaves of the injured camellias and seriously affect their growth. At the same time, the excrement of aphids can also cause bituminous disease.

Control methods: in the early stage of being injured by aphids, camellia plants can be sprayed with 2000 times of 50% phosphamine milk or 50% dimethoate emulsion every 3 to 5 days, and aphids can be eliminated about 3 times. Another method is to use 0.5 kg of cigarette sticks, 0.25 kg of quicklime, add water (about 10 to 15 liters), soak for one day and night, filter and remove slag after spray prevention.

2. Scale insects

What about the camellia worms? It's probably the kind of bug that looks like this. There are many species of scale insects, among which three kinds of scale insects are seriously harmful to camellias. The number of eggs laid by scale insects is very large, and each female can lay about a thousand eggs, which can lay 3 or 5 times a year. Therefore, when it is serious, the branches and leaves are covered with scale insects to absorb leaf liquid. The damaged leaves changed from green to grayish green and finally to yellow, resulting in the death of the whole plant.

Control methods: because most of the insects are concentrated, it is easier to find that the insect can be killed directly on the branches and leaves when the number is small in the early stage. If the number of insects is relatively large, it is necessary to grasp the characteristics of weak drug resistance of newly hatched nymphs and grasp the period of drug application. The body surface of the adult is waxy, and the effect of spraying is poor.)

3. Stem borer

Harm the branches of camellias, so that the killed branches wither and die. The harm is usually from March to April and from August to September.

Control method: cut off and burn the branches that give birth to stem borer, and trap and kill adults with light. During the peak period of adult Eclosion, 20% dimethoate emulsion 500 times or 90% trichlorfon 1000 times solution can be sprayed, and 90% trichlorfon 500 times solution can also be used in larval stage.

4. Dendrolimus spiniferus

Absorb the sap on the leaves, harm the insects of camellia leaves, its secretion can also lead to a large number of bituminous coal disease, seriously affect the normal photosynthesis of camellias, serious will cause a large number of falling flowers and other phenomena.

Control method: cut off the branches and leaves with insects and burn them centrally in winter or early spring. In the nymph incubation period, you can use imidophos, marathon, or dimethoate spray, once every 7 days, can be effectively controlled. Through the above answers, I believe we all know how to do camellia insects, camellia disease and pest control bar, let's take a look at camellia disease control.

III. Disease control of camellia

1. Anthrax

This disease is one of the common diseases of camellia, which usually occurs on the leaves of flowers and seedlings from June to July, and the disease spot starts from the leaf tip or leaf edge. At the beginning, water-stained green-brown disease spots appeared at the edge of the basal leaves, and then expanded into a layer of small black spots arranged in irregular large stripes to spread to the whole leaf, and finally caused the leaves to fall off.

Control methods: strengthen cultivation management, pay attention to the application of organic fertilizer and phosphorus and potassium fertilizer, improve plant disease resistance, remove diseased leaves and burn them in time. After the spring shoot grows, spray with 1% Bordeaux liquid to prevent bacterial infection. At the initial stage of the disease, 65% Dyson zinc wettable powder was sprayed with 600 times aqueous solution, or 70% methyl topiramate wettable powder 1000 Mel 1500 times was sprayed.

2. Soot disease

The disease can damage the branches and leaves, especially on the leaves. At the initial stage of the disease, soot-like mildew spots appeared in the disease, and then gradually expanded and connected to each other into pieces, so that most of the plants were covered by soot-like mildew layer. After parasitism, the pathogen not only absorbs the nutrients of flowers, but also seriously affects the photosynthesis and respiration of plants, resulting in a large number of fallen leaves.

Control methods: planting should not be too dense, keep the plants in good condition of ventilation and light transmission. Do not make the humidity too high, control the conditions for the growth of germs. During the onset of the disease, Baume 0.3 degree stone-sulfur mixture was sprayed once every 10 seconds for 15 days, for a total of 3 times. You can also use 50% tophan wettable powder 500 times liquid spray, 7 murine once every 10 days, spray 3 times, can receive the therapeutic effect.

3. Root knot nematode disease

The disease harms the roots of camellias, turning them dark brown and causing nodules to rot and break. The main root was enlarged, the new beard was not born, and the ground plant stopped growing, which gradually led to the death of the whole plant.

Prevention and control methods: disinfect the cultivated soil and kill the disease-causing insects before putting on the pot. Immediately after ② found the patient, the sterilized culture soil was used as the basin soil to change the basin. Before changing the basin, the potted soil can be used again after 3 days of exposure in the scorching sun factory. The soil can be disinfected by spraying the soil with dibromochloropropane and 100Mel 150 times water, but the soil after using this drug must be stacked for 20 days before it can be planted in the pot. Otherwise, it will damage the root system. The above is the whole content of the prevention and control of camellia diseases and insect pests, and what to do about camellia insects. I hope I can help you.
