What medicine is used for pepper insects? What is the best insecticide for pepper trees?

1. What are the more common insect pests of Zanthoxylum bungeanum trees? The use of Sichuan pepper is relatively wide, it can be used as a seasoning, and can also be used to refine sesame oil, use medicine and produce soap and other products. As a plant with its own rue fragrance, the fruits and plants of Zanthoxylum bungeanum also have certain insect repellent and insect repellent effects, but it does not mean that Zanthoxylum bungeanum will not be eroded by insect pests during the growth process.

Scarabs, stinging moths, longhorn beetles, scale insects, red spiders and aphids are particularly common insect pests of pepper trees; According to rough statistics, there are more than 130 kinds of insect pests that may be eroded during the annual growth of peppercorns. In order to improve the yield and quality of Zanthoxylum, it is extremely important to take timely pest control measures.

2. Drugs commonly used for pest control of peppercorns. Since there are so many pests in the pepper tree, how should it be controlled? The most important thing is to prescribe the right medicine and spray it in time, and there are differences in the drugs corresponding to all insect pests and their different stages of development.

For example, scale insect pests mainly suck the sap in new branches, sprouts and young leaves of Zanthoxylum bungeanum pepper, and in severe cases, the whole plant may die; Adult scales are also one of the most difficult pests to control, and it is very difficult for drugs to penetrate into them, and it is necessary to use 1000 times the liquid of dimethoate to spray and kill them many times at the larval stage. There is also a red spider with strong reproductive ability, which is also difficult to control, and breeds more than 6 generations a year, which is more serious about the erosion and damage of the flowering period of Zanthoxylum bungeanum pepper; It can be fully sprayed with the amount of acaricidal net, gram mite or dimethoate. In order to reduce pesticide damage and damage to natural enemies of insect pests, broad-spectrum insecticides are not used as much as possible.

3. Improve yield through scientific cultivation and fertilizer and water management. To ensure the overall yield efficiency of Zanthoxylum bungeanum trees, pest control and fertilizer and water management are extremely important and mutually reinforcing. Good planting management and good fertilizer and water control are also important guarantees for reducing the erosion of diseases and insect pests of Zanthoxylum bungeanum trees.

The breeding methods of Zanthoxylum bungeanum trees are mainly based on sowing seedlings and cuttings, and can be planted in plots with good ventilation and sunshine and good drainage and irrigation. The cultivation of pepper trees is mostly in spring and autumn, and the depth of soil cultivation can be controlled at about 20 30 cm, and the soil should be sanitized in advance, and sufficient rotten farm manure and soil miscellaneous fertilizer should be applied. In addition, the planting density of Zanthoxylum bungeanum is also very important, and reasonable planting density has a certain impact on preventing the spread of pests and diseases and reducing shading. According to the slope of the mountain and the sunshine conditions, it is generally enough to plant 150 200 plants per mu.

In the later stage of growth, appropriate topdressing of phosphorus, potassium fertilizer and calcium fertilizer, and regular pruning of branches and leaves are also important tending measures to improve the yield of Zanthoxylum bungeanum trees.

You can choose to solve this problem with some insecticides, or you can spray some pesticides.

1. Zanthoxylum red spider. Multi-generation damage occurs in a year, the damage begins at the germination stage of Zanthoxylum, the damage is serious at the flowering stage, the degree of damage of red spider is related to temperature and humidity, and the damage is easy to occur in high temperature and drought. During the incubation period of red spiders from April to May, use 1000 times of dimethoate oxide, or 800-1000 times with 40% speed to kill for control.

Pesticides such as acaricide and mitete are also used for spray insecticide in accordance with the instructions.

2. Aphids. A year can reproduce 20-30 generations, eggs overwinter on the pepper tree, hatch in March in the beginning of spring and begin to harm the young shoots of Zanthoxylum, continue to reproduce on the tree body after 2-3 generations, produce winged viviparous aphids, winged aphids will move to other farmland to harm other crops, and some of them return to the pepper field in August to harm Zanthoxylum pepper for the second time. It can be sprayed with 8 ml of dissolute and 15 ml of Huifeng crack mixed with 30 kg of water.

When the insect pest is serious, compound preparations such as 8 ml of quick culling + 4 ml of avermectin can be used to control the pesticide with good control effect.

Special plant insecticides should be purchased, evenly sprayed on the leaves of peppercorns, and should not be watered during the medication, otherwise there will be no effect.

It's just ordinary, imidacloprid, acetamiprid, and thiamethoxam are OK, mainly to prevent and control aphids.

What is the specific reason: there are many pepper pests and pepper tree deaths, mainly pepper leaf rust, root rot, black shin disease (gum disease) and Huatianzhuan cattle, leaf creep jumping beetle

Diseases and insects such as scarab aeruginosa, mulberry white scale, and gall mosquito need to be sprayed differently. Don't know what disease your tree is? At present, in late April, the buds of pepper trees are susceptible to pepper leaf miners, and pepper farmers call it "fire wind".

With 1:1:3:

1000 times dichlorvos, dimethoate, methamidophos solution spray, the disease rate of young shoots of Zanthoxylum pepper can be reduced to less than 1. Zanthoxylum pepper was sprayed once before flowering, 1:1600 1800 times dichlorvos solution.

Immediately after the pepper flowers, spray 1 time 40% dimethoate emulsion 800 1000 times solution. Spray again 1 time after 10 days to prevent larvae from transferring damage.

Every spring to autumn, pepper trees can be overgrown with aphids. At a glance, there are swarms of ants in the trees, indicating that the harm of ants is already very serious。If you look closely, the leaves will be deformed, and even cannot grow normally, and the harm to the growth of young pepper trees and large-flowered pepper trees is not inferior to other pests and diseases.

People often use insecticides such as cypermethrin, aphids, and imidacloprid to control pepper aphids. Drug resistance often arises, and the dosage has to be increased and repeated use. Not only is the effect not good, but the pesticide residues exceed the standard, which is difficult to sell.

Price. After years of testing and application, the insecticide made by this method has a good control effect on Zanthoxylum pepper aphid. The biggest advantage is that there is no resistance.

Tobacco control peppercorns. There is a habit of growing tobacco in rural areas, especially in families with elderly people. They love to smoke.

There will be a lot of cigarette sticks, moldy tobacco shreds, and cigarette butts。They usually pile up and can be used when aphids appear on pepper trees. Very useful.

Soak the stick, butt, and shreds of tobacco in water, then spray carefully, not allowing any part of the plant to leak out, and the spraying volume should start with water droplets. If there are too many aphids, the medicine can be applied at one time, and the aphids at the bottom do not come into contact with the alkaline liquid. It can be sprayed every 5 days to control the number of aphids.

The specific method of use is: cut the cigarette stick into small pieces, add 15 kg of water to one pound of cigarette stick, soak for 24 hours and then apply. After the shredded tobacco is chopped, add 20 kg of water to one pound of shredded tobacco and soak for more than 12 hours.

Soak the cigarette butts in water for more than 12 hours, dilute them at a ratio of 1:10 and spray. The soaked tobacco water filters out impurities and sprays to avoid clogging the nozzles.

The aqueous solution of tobacco is strongly alkaline. It acts on the surface of the aphid, causing the waxy layer on the surface of the aphid to melt and enter the body of the aphid through the stomata, causing the aphid to lose water and die. The effect is very noticeable.

Plant ash controls capsicum aphids. Plant ash is the best potassium fertilizer and can also control pepper aphids. In the early stage of aphids, add 5 catties of water with one pound of plant ash, soak for 24 hours, and then take out the clear liquid and spray it.

The effect is good, and it can also play a role in supplementing potassium fertilizer. Orange peel and chili pepper control pepper aphidsMost families like to eat oranges and sugar oranges. There is a lot of dried orange peel at home.

When aphids are found on the pepper tree, you can use one catty of orange peel and half a catty of chili powder and 10 kg of water to boil. Let stand for 10 minutes, then let stand for 24 hours, take out the serum and spray it on the leaves, which has a strong contact killing effect. If there are a lot of aphids, you can spray them every 3-5 days.

Laundry detergent water to control chili pepper aphids. Laundry detergent has a strong cleaning effect, mainly contains strong alkaline substances and surfactants, and the aphid-killing effect can reach more than 95%.。Sichuan pepper trees are generally sprayed with one or two washing powders and 80-90 kg of water.

When the damage of aphids is severe, spray 2-3 times every 3-5 days to eliminate all aphids. If a little urea is added, the insecticidal effect can be enhanced, and nitrogen fertilizer can also be added.

thiamethoxam, pymetrozine, acetamiprid, dinotefuran, etc., the effect is very good, can have a good deworming effect, do not use some drugs at will, with a certain danger.

You can use enylpymetrozine, pymetrozine, clothianidin, thiamethoxam, pymetrozine, acetamiprid, dinotefuran and so on. I think the effects of these drugs are very good, but I don't know what the final result will be.

The drugs with better effects are insecticides, insect pesticides, insecticides, herbicides, fertilizers, insect repellents, and insecticidal sprays.

Sichuan pepper is a master of insect control and insect repellent.

Sichuan pepper is insect repellent because it is a natural antioxidant with a special fragrance. Rice worms are very sensitive to smells, and they are even more afraid of this special smell.

You can take 30 peppercorns, wrap them in 3 to 5 gauze bags with good air permeability, and put them into the bottom, middle, left, right, and upper part of the bag where the rice noodles are stored, and then seal the mouth of the rice noodles bag tightly, which can effectively prevent insects.

Sichuan peppercorns can repel ants.

Zanthoxylum bungeanum is a natural antioxidant with a special fragrance, and ants live by smell, relying on smell to find food, relying on smell to communicate, etc., the smell of Zanthoxylum pepper will interfere with the normal life of ants, so ants should be able to escape the smell of Zanthoxylum.

Sprinkle the peppercorn powder on the ground where ants often crawl, and then sprinkle the pepper powder in the cabinet or the four corners of the room, the effect of repelling ants is better than that of peppercorns.

Hello, Sichuan pepper can kill insects, as long as you add another kind of laundry detergent or the like, you can kill the insects.

Zanthoxylum pepper cannot be used to kill insects, because it is only a condiment and has no insecticidal effect.

Zanthoxylum pepper has the effect of sterilization, anti-inflammatory and insecticidal, of course, Zanthoxylum pepper is mainly used in the production of some foods, and it is not very useful for sterilization and insecticide.

Sichuan pepper is a medicinal and edible medicine, which has the effect of relieving pain in warmth, killing insects and relieving itching.

Hello dear with avermectin, low toxicity. Pests should use high-efficiency low-wheel bridge douxin pesticides as much as possible. The leaves of the pepper tree are hard and hard, generally easy to grow in the mountains, green and ecological, and it is best not to spray pesticides.

The pests of the wax grinding on the pepper tree should be zinc sulfur and dichlorvos, but they should be prevented early, and the effect should be better at the egg stage. Pests on pepper trees are generally not controlled with pesticides, and biological control is adopted. Avermectin plus imidacloprid has a good control effect.

Spraying low-toxicity avermectin is fine. See what insects spray what medicine, pay attention to the use of low-toxicity and high-efficiency pesticides. The pests on the pepper tree are mainly aphids, which are controlled with imidacloprid.

The insects on the pepper tree are called citrus butterfly larvae. The larvae of the orange butterfly like to eat citrus and pepper leaves, and do not eat the same pomelo leaves of the genus Spice, the larvae are about 45mm long, and mainly live in the Yangtze River basin and the north of the region. There are two types: spring type and summer type.

The spring shape has a body length of 21-24 mm and a wingspan of 69-75 mm. The summer shape is 27-30 mm long and has a wingspan of 91-105 mm. The female is slightly larger than the male, the color is not as bright as the male, the markings on the wings of the two types are similar, the body is pale yellow-green to dark yellow, there is a black longitudinal band in the middle of the dorsal body, and the sides are yellowish-white.

Habits of citrus butterfly larvae:

Adults are active during the day. Good at flying, the most active from noon to dusk, likes to eat nectar. The eggs are laid loose on the buds and on the back of the leaves, and the egg stage is about 7 days.

After hatching, the larvae first eat the egg shell, and then eat the buds and young leaves and adult leaves, a total of 5 instars, after the maturity of the old and mature more in the hidden place to spin silk as a pad, with the hip toe hook to grasp the silk pad, and then spin the silk in the chest and abdomen around the belt, wrapped on the branches and other things to pupate and overwinter. The natural enemies include the butterfly, the golden wasp and the broad-legged wasp. 1 year, 3-6 generations overwintering with pupa.

In March and April, they emerge into spring-type adults, and those that emerge in July-August are summer-type, and the generations in the field overlap. Adults mate during the day, and the eggs are laid on the back of young leaves or at the tips of leaves. The larvae feed here after hatching and can feed on 5-6 leaves in their lifetime.

When the larvae are frightened, they stretch out the smelly horn to emit an unpleasant smell to avoid predators, and when they are old, they will spin silk as a cushion and hang obliquely in the air to pupate.

Sichuan pepper is a common spice that has insecticidal and insect repellent properties. If you want to use peppercorns to kill insects, you can try the following methods:

1.Dry pepper powder is mixed with powdered white sugar and used as an insect control agent for ants, cockroaches and other pests both indoors and outdoors. Place the mixture in enclosed, bug-infested areas, such as under sinks, empty shirt corners, living areas, etc.

2.After drying, grinding pepper into powder, mixing it with water to form a paste, spraying it on plants or fruit trees to kill insects.

3.Place the ground pepper in a cloth bag or gauze, and place it in a dry space such as a wardrobe or study to avoid damage to clothes and books by pests such as clothes moths and bookworms.

In conclusion, Sichuan pepper can be used as a natural, green insecticide, which is very effective in the control of some small pests. However, for some large, more serious pest problems, other effective pesticides are also needed.

Summary. Hello dear.

Hello dear. The effective agents for the prevention and control of Zanthoxylum pepper aphids are pyritrazine, pymetro, thiamethoxam, pymetro, clothianidin, thiamethoxam, pymetrozine, acetamiprid, dinotefuran, etc., and the fast-acting agents are pyrethroid agents and chlorpyrifos, which can usually be used together, and can also be traced to add osmotic agents such as silicone, which is conducive to enhancing the control effect.

Hope this helps<>
