Honeysuckle seedlings summer pests and diseases, how should we solve them?

In people's lives, when it comes to anger, most people think of honeysuckle soaking in water and drinking. As a traditional Chinese medicine in China, honeysuckle has a very good market demand. Many of the raw materials of proprietary Chinese medicine have their ingredients.

Let's learn about honeysuckle field management and pest control.

1.Brown spot disease.

Brown spot disease is common in the high temperature and high humidity season from June to September, and mainly damages leaves. Diseased leaves can be washed and removed, and phosphorus and potassium fertilizers can be applied appropriately. At the beginning of the disease, spray 1:

1:200 times Bordeaux liquid or 500 times 65% zeb wettable powder, which can enhance the disease resistance of honeysuckle.

2.Coffee Tiger Bull.

The coffee beetle is active in May-June, and the larvae will eat honeysuckle over 5 years old, mainly harming the branches. During the adult growth period and the larval incubation stage, 80% dichlorvos emulsion can be sprayed 1000 times in advance. or use sugar, vinegar, water, trichlorfon in proportion to trap and kill adult insects; Or it is the natural enemy of the longhorn that releases the coffee tiger in the adult stage, that is, the control of the longhorn beetle.

3.Silver inchworm.

The tea inchworm is a pest that feeds mainly on honeysuckle. It mostly occurs from June to September and bites the leaves. It can clean the garden in winter. It can be controlled by spraying 1000 times of 80% dichlorvos EC or 800-1000 times of 95% crystal trichlorfon.

After the honeysuckle seedlings are planted, they should be ploughed and weeded in time. During the operation, attention should be paid to the depth first and then the shallowness to avoid injury to the roots. After weeding, ridges should be set in early spring and after autumn before freezing to prevent the root system from being exposed.

Dig a shallow ditch around the flower mound, cover it with soil after spreading fertilizer, and determine the amount of fertilizer according to the size of the flower mound, mainly to apply farmhouse fertilizer and a small amount of chemical fertilizer. Usually, for perennial flower mounds, 5 kg to 6 kg of farm manure and 50 g to 100 g of compound fertilizer are applied. After fertilization, top dressing can be carried out according to the actual situation, and the fertilization effect is good after ridge formation.

In the first two years after planting, choose to leave 2-4 seedlings with good growth and developed trunks, cut off the excess shoots, and repeatedly remove the side buds, so that the honeysuckle can be better shaped into an umbrella shape, and then pruned every winter and summer. Winter pruning: In accordance with the principle of "light pruning of strong branches, heavy pruning of leading branches, full pruning of dead branches, and pruning of all branches", 8-10 pairs of strong branches should be left with buds, 3-5 pairs of weak branches should be retained, and all diseased branches, thin dead branches, winding branches, and high branched branches should be cut off.

Summer pruning: Usually after harvesting the flowers of the previous stubble, the tips of the well-growing branches are cut off, and the small branches with weak growth and the yellow leaves that affect the ventilation and light transmission of the whole plant are cut off. Remember to prune lightly during the summer pruning process, which is conducive to sprouting new branches and increasing yield.

After the seedlings are planted, it should be ploughed in time, regular weeding, should follow the principle of deep and shallow, after sprinkling fertilizer, it should be covered with soil, according to the size of the flower tons, so as to determine the amount of fertilizer, you can also add a small amount of chemical fertilizer, compound fertilizer, and later can also be topdressed, and the branches and leaves should be pruned regularly, and pesticides should be sprayed regularly to prevent and control insect pests.

When this happens, it is necessary to water it in time, drain the soil, choose the right insecticide according to the type of pest and disease, and prune off the rotten roots or leaves.

This problem can be solved by spraying pesticides, spraying insecticides, spraying nutrients on plants, watering and turning soil.

Before germination in spring, sprinkle 1% trichlorfon powder around the dry perimeter, 15 grams per mound, then cultivate soil, and sprinkle phosphine around the trunk with 50-100 grams per mound. In winter, pruning is combined to remove insect branches and eliminate overwintering larvae.

We should spray some pesticides to prevent pests and diseases, so that we can control honeysuckle pests and diseases very well, and the effect is also very obvious.

Pesticides should be sprayed in time to prevent pests and diseases, or the surrounding soil should be treated, which can also prevent the occurrence of pests and diseases.

Cut off the diseased leaves and spray them with Bordeaux solution in a ratio of 200 to 1 time every 7 10 days for 2 3 times, or with a 500-fold dilution of 65% zebsen zinc or a 1000-1500-fold dilution of Tobuzin, spray once every 7 days for 2 3 times.

Common pests and diseases of honeysuckle are aphids, which can damage the leaves, cause curling up and stop growing, so they need to be treated with drug sprays.

There is also powdery mildew. The disease is more serious in hidden places, which will cause flower fall and dry branches, so it is necessary to clean up the residual beads in time and spray them with drugs.

Honeysuckle can also have brown spot disease, which causes the plant to weaken and need to be pruned and sprayed with medicine.

In ordinary life, when it comes to fire, most people will think of soaking honeysuckle in water to drink, and honeysuckle, as a traditional Chinese medicine, the market demand is really good, many Chinese patent medicine raw materials have its ingredients, the following is the main research to understand honeysuckle field management and pest control.

1. Field management of honeysuckle.

1.Cultivating and weeding.

After the honeysuckle seedlings are planted, they should be cultivated and weeded in time, and the operation should be paid attention to the first deep and then shallow, do not hurt the roots, and then freeze in early spring and autumn after weeding* to prevent the roots from being exposed.

2.Scientific top dressing.

Dig a shallow trench around the flower pier, sprinkle * cover, and the amount of fertilizer is determined according to the size of the flower pier. Usually perennial large flower mound, apply farmhouse fertilizer 5kg-6kg dun, compound fertilizer 50g-100g dun, fertilizer can be topdressed according to the actual situation, * fertilization effect is good.

3.Trim. In the first two years after planting, 2 4 plants grow well, the trunk of the original seedling grows vigorously, the leaf tips and branches are cut off, the edge buds are repeatedly pulled, and after pruning in winter and summer, honeysuckle can form a good umbrella shape.

Winter scissors: according to"10 pairs of buds, 3 5 pairs of buds, weak branches, thin dead branches, winding branches and high forked branches are cut off 8 10 pairs of buds, 3 5 pairs of buds, weak branches, thin dead branches, curly branches and high forked branches.

Summer flower cutting: Usually after the first stubble flower harvest, the top of the growing branches is cut off, and the weak branches are cut off, and the leaves turn yellow, affecting the ventilation and light transmittance of the whole plant. Remember, during the summer harvesting, it is necessary to cut lightly, which is conducive to the germination of new shoots and the increase in yield.

Second, the prevention and control of common pests and diseases of honeysuckle.

1.Brown spot disease.

Brown spot disease is more common in the high temperature and high humidity season in June and September, mainly harming leaves, removing diseased plants and leaves, appropriate application of phosphorus and potassium fertilizer, and spraying 1 1 2 0 0 times or 6 5% zinc wet powder 5 0 0 times in the early stage of the disease, which can improve the disease resistance of honeysuckle.

2.Coffee Tiger Bull.

Coffee tiger beetle is active in May and June, the larvae will eat honeysuckle over 5 years old, mainly damage the branches, in the adult growth period and the larval initial hatching period can be pre-sprayed 80% dichlorvos emulsion 1000 times; Adults can be trapped in a ratio of sugar, vinegar, water, and trichlorfon 1:5 4; Or release the natural enemy of the coffee tiger beetle in the adult stage, that is, the natural enemy of the white moth, that is, the natural enemy of the white moth, which can be sprayed with 80% dichlorvos emulsion 1000 times in advance.

3.Honeysuckle nematode.

Honeysuckle nematode disease is a honeysuckle-dominated pest that occurs in June and September and can be used to clean the countryside in winter by spraying with 80% dichlorvos EC 1000 times solution or 95% crystalline trichlorfon 800-1000 times solution.

To sum up, some planting skills of honeysuckle, honeysuckle is actually not very strict with soil requirements, compared to many Chinese herbal plants are irresponsible for planting.

The key point of control is that pesticides need to be sprayed regularly to achieve a pest control effect, and attention should be paid to the drainage and irrigation of the land, to avoid too humid terrain environment.

You can use more pesticides, so that it can play a good role on the surface, and it has a huge effect on the maintenance of honeysuckle

Observe honeysuckle more, spray some pesticides at a stage of growth, and pay attention to the ratio of pesticides to water when becoming pesticides.

3. Biological controlIf you want to grow your own honeysuckle, which is particularly green and healthy, you can use biological control. Natural enemies of evolutionary pests and diseases can be attracted, and then these pests and diseases will be driven away, so that honeysuckle can grow vigorously and healthily. In short, we should always pay attention to the growth of honeysuckle, and if we find something wrong, we must immediately take corresponding measures to prevent honeysuckle from being attacked by pests and diseases.

After infection, the branches will lodging and die. Rust: It is highly susceptible to infection in humid environments.

Powdery mildew: Severe in warm, dry or shaded environmental conditions, with small white spots on the leaves. Spider mite, aphid infestation:

The larvae suck up the sap from the leaves, causing the leaves to curl, yellow flowers, and eventually fall off. Longhorn beetle: The larvae burrow into the xylem and eat the base.

Hello, please refer to it.

Agricultural measures can be carried out, such as improving the disease resistance of plants, strengthening cultivation management, removing diseased branches and buds, reducing soil moisture, proper pruning, and increasing organic fertilizer.

Honeysuckle pests and diseases mainly include brown spot, aphids, coffee pot beetle, leaf spot, etc., comprehensive control can use professional pesticides to remove diseases and insects, as long as spraying in accordance with the standard dose on the instructions, it can be effectively controlled.

And you need to buy some chemical raw materials to prevent harmful insects from biting the trunks of these flowers. Because honeysuckle is a relatively fragile plant, it also needs to be careful when maintaining it, and it cannot be concentrated in too hot places, as direct sunlight will cause evolution to wither, so we must pay attention to these problems. In addition, to prevent insect pests, regular check-ups are also necessary to ensure that such plants can survive better.

Common diseases of honeysuckle are brown spot, powdery mildew, insect pests mainly aphids, red spiders, it is strictly forbidden to use highly toxic, high residue or with three pesticides, in the use of mixed organic synthetic chemical pesticides, mixed chemical pesticides can only be selected as specified varieties.

Spray pesticides, choose the right varieties for planting, pay attention to the soil, pay attention to the density of planting, pay attention to light.

Spider mites are a kind of mite pests that harm honeysuckle, red spiders have small bodies, mainly swarm on the back of the leaves to suck sap, causing honeysuckle leaves to curl, yellow, and finally fall off. The environmental conditions of high temperature and dry air are very likely to cause the occurrence of red spiders. Prevention and control methods:

Prune in time to remove old leaves and decaying branches; Improve ventilation and light transmission environment. Spray 2000 times of thiofenone solution, or 2500 times of egg mite net solution for control, use the drug once every 7 to 10 days, and spray 2 to 3 times continuously, with good effect. Severe occurrences usually occur between April and June.

Aphids mainly damage the leaves, clustering on the front and back of the leaves, with the back being the majority. The young leaves are more severely damaged, causing the leaves and flower buds to curl and stop growing. Aphids can secrete honeydew when they are harmed, resulting in bituminous coal disease, which not only affects the growth of honeysuckle plants, but also affects its ornamentality.

Control method: 1000 to 1500 times of 40% dimethoate emulsion, or 1000 to 1500 times of aphid pine can be sprayed, and the effect is good for 2 to 3 times in a row.

Be sure to spray pesticides in time, and also clean up the fallen leaves in time, burn them intensively, and avoid breeding a lot of bacteria.

Pest control: In addition to reducing the source of the disease and strengthening the management, in the early stage of the disease, plant protection measures such as physical or pharmaceutical agents can be used to kill pests and diseases, and a new high-fat film can be added to enhance the active ingredients of pesticides to ensure the robust growth of plants.

Field management: loosening soil, soil cultivation, watering, fertilization, pruning, fertilization and soil cultivation at the same time, reasonable watering, pruning too long branches, diseased branches, dead branches, downward extension branches, so that the branches are erect in clusters, the main trunk is thick, the branches are dense and even, and the pruning mouth should be coated with callus antiseptic film to promote wound healing as soon as possible.

Growth period: After pruning, new branches are generated, and flowers are sprayed at the bud stage, which can effectively inhibit vegetative growth, promote the development of flower buds, enlarge petals, improve medicinal substances, and pick flowers in a timely manner.

Overwintering protection: apply overwintering fertilizer at the end of autumn every year, loosen the soil, kill pests and diseases, paint the tree body, spray a new high-fat film on the ground, report moisture, protect fertilizer, keep warm, prevent cold, and safely overwinter.

The main diseases of honeysuckle are powdery mildew and leaf spot, and the main insect pests are coffee tiger, aphid, leaf bee, honeysuckle, etc.

The following pesticides have different names depending on the region, and they can be selected according to their efficacy.

a) Powdery mildew.

Damage to honeysuckle leaves and young stems. At the beginning of the disease, round white velvety mold spots appear, which then expand and connect into patches, forming white pink spots of different sizes. Finally, it causes flower drop, leaf withering, and drying up the branches.

Prevention and control drugs: colloidal sulfur, trichlorfon, dimethoate, pink embroidery, DuPont Yibao and so on.

b) Aphids. It generally begins to occur around Qingming and is mostly on the back of the leaves. In cloudy and foggy days before and after the beginning of summer, when the east wind blows, the damage is extremely serious, which can make the leaves and flower buds shrink, stop the growth, and cause a serious reduction in yield. Generally, it can be controlled by spraying 800-1000 times of 40% dimethoate emulsion once during Qingming and Guyu.

Pests of honeysuckle and the common pests it controls: carrot microtubule aphid.

Eggs can be used to reduce insect infestation, and spraying 3-5 Baumé stone sulfur mixtures can effectively kill eggs. In order to prevent the migration of insect pests, 10% imidacloprid wettable granules can be sprayed 2000 times in early spring, or 1% azadirachtin agent 800 times.

Common pest: Elm hornworm.

The elm worm moth has spike phototaxis, so it can be used to install black lights for booby-trapping. There is also the option of spraying insecticides on the roots of the plant for extermination.

Diseases of honeysuckle and its control.

Most of the diseases of honeysuckle are caused by fungal infections, so in daily care, water and fertilizer management should be continuously strengthened, and attention should be paid to the pruning of plants. When brown spot disease is found, it can be sprayed once a week with 65% zebsen visible particles 600 times, and sprayed continuously for three to four weeks, which can be effectively controlled.

When powdery mildew is found, you can choose 1000 times of 75% chlorothalonil wettable granules and spray them once a week, three to four times in a row, and you can suppress the disease in time.

In order to control the occurrence of coal pollution disease, we must first control the harm of aphids, and secondly, select 1000 times of 75% methyl tobuzinchai rolling wettable particles for prevention and control, and also prepare for swimming once every seven days, spraying three to four times in a row.
