1.Dimethoate: It has fumigation, so it should be used in the morning on a sunny day or when the temperature is low in the afternoon, and the effect can be seen a day or two after use.

2.Imidacloprid: systemic insecticide, which has a good control effect on aphids and other pests.

3.Malathion: a relatively common contact insecticide, it has a good control effect on a variety of pests, but be careful not to pollute the water source.

4.Acetamiprid: systemic insecticide, a nicotinoid insecticide, mainly for aphids, scale insects, whiteflies, etc., with fast effect and no resistance.

5.Fluoxystrobin: a high-efficiency, low-toxicity and broad-spectrum fungicide, which has a good control effect on the appearance of oil sweat in Zanthoxylum.

6.Carbendazim: a broad-spectrum and efficient fungicide, which has a good control effect on a variety of pathogenic bacteria, and also has a certain effect on the appearance of oil sweat in Zanthoxylum bungeanum.

7.Sulfur fumigation: a physical control method, it has a good effect on the appearance of oil and sweat of Sichuan pepper, but pay attention to the fumigation time and temperature.

It should be noted that when using pesticides, they must be prepared and used in accordance with the instructions on the package, and do not change the use method and dosage at will, so as not to cause pesticide damage or reduce the prevention and control effect. At the same time, it is also necessary to pay attention to safety when using pesticides, wear protective gloves and masks, etc., to avoid poisoning or polluting the environment.

The oil sweat on the pepper is actually an aphid, and the control of aphids can be done with the pesticide fluridine pymetrozine, and the insecticidal effect is good.

Spray stone sulfur mixture, after the leaves of Zanthoxylum pepper fall, or before germination, spray 3 5 Baumé stone sulfur mixture, spraying should be careful and thoughtful, the whole pepper tree should be sprayed, so that some overwintering aphids can be killed, reduce the number of aphids after germination.

Before spraying the stone sulfur mixture, remove the dead branches and leaves of the pepper tree that are damaged by diseases and insects, remove the outside of the pepper orchard, and then spray the stone sulfur mixture.

The use of natural enemies, aphid flies and ladybugs, are the natural enemies of aphids, when spraying pesticides, try to use insecticides that are less harmful to natural enemies, if you use stocking ladybugs or aphid flies to control aphids, you must pay attention to the safety of medication during the release.

Fertilization Management:

Zanthoxylum bungeanum fertilization is mainly divided into basal fertilizer and top dressing, the role of basal fertilizer is to promote the differentiation of flower buds of Zanthoxylum bungeanum trees, improve leaf photosynthesis, restore tree potential, and lay the foundation for the high yield of Zanthoxylum bungeanum in the following year.

The base fertilizer is mainly organic fertilizer, generally after clearing the garden in autumn, open a 40 cm deep ditch at the drip line of the crown, apply organic fertilizer kilograms and superphosphate kilograms according to the young trees, and apply organic fertilizer kilograms and superphosphate kilograms to adult trees into the ditch, and then cover the soil.

Top dressing is generally carried out in the fruit expansion period, according to the amount of topdressing gram urea and kilogram of superphosphate per plant, which can not only effectively promote the growth of new shoots, but also improve the fruit setting rate and promote the growth of fruit ears.

Hello dear The oil sweat on the pepper tree is not a stubborn disease, and it is generally easy to extinguish. The author said that we used to use pesticides in the field to prevent and control it, and there are many pesticides to eliminate oil and sweat, and you can choose two kinds of sprays: worm curd, malathion, dimethoate, acetamiprid, chlorpyrifos, and matrine.

Some of these pesticides have fumigation, some are highly efficient and low toxicity, low residue, not easy to produce resistance, all have contact killing, and they are all buried in the hands of the nemesis of oil and sweat. Generally, it is advisable to choose two kinds of combinations, dimethoate has fumigation, which can be used as the first choice for convention, and then it is the best to choose the same as casually. When spraying, it must be careful, to a branch and a skill, from the bottom of the tree to move up in turn, the air pressure Zheng Liang to be enough, generally the first day sprayed the medicine, the next day will be significantly better.

When spraying, you can add some laundry detergent to the water to help, and you can put 1oo grams to 200 grams per 100 catties of water. It mainly acts on the adhesion between the potion and the leaves.

Kiss hello <>

The oil sweat on the pepper tree can be stopped with a polyestericidal drug. Before the fifth month of the lunar calendar, prepare a small amount of phosphorus imitation potassium dihydrogen dihydrogen foliar spray, and after 10 days, single spray of chlorfenloprid and oxidized dimethoate emulsifiable concentrate, once every 10 to 12 days.

Oil sweat is a common name, the scientific name is aphid, aphid is the most common pest on flowers, belonging to the Homoptera, aphid family, because the aphid compound insect can secrete a large amount of dense juice, so it is also called greasy insect, dense worm. Aphids are highly adaptable to climate, widely distributed, small, fecund, and have huge populations. One generation can be bred in 4 to 5 days in summer, and dozens of generations can be bred in 1 year.

Due to a large number of reproduction, young leaves, young stems, rotten oranges, flower buds and other tissues and organs are soon covered with aphids, which makes the damage aggravated. Aphids suck the stems and leaves of the plants with stinging and sucking devices, especially the young parts, absorb the nutrients in the body of flowers, and often live in groups, causing the leaves to shrink, curl and deform, so that the growth and development of flowers are retarded, and even withering and dying. The secretion of aphids not only directly harms flowers, but also acts as a good medium for pathogens.

As a result, coal stain disease and other further damage to flowers. Aphid hosts are complex and diverse, have a long damage period, and are also the main vectors for the transmission of viral diseases, so they must be treated early, continuously and thoroughly. For the control of chemical agents, 2000 times of 50% aphid mist ultra-fine wettable powder or 1500 times of 20% methocarb EC, 1000-1500 times of 50% aphid pine EC, 2000 times of 50% octafen thiophos EC, and 1000 times of 80% dichlorvos EC.

I wish you a happy life! Hope mine is helpful to you ha.

Summary. Aphids on pepper trees are more difficult to control. More than three kinds of insecticidal pesticides can be used to spray well in a certain proportion. It has a relatively good prevention and control effect. For example, use 5% acetamiprid plus 20 imidacloprid and add cyhalothrin and other mixed sprays.

Can't kill all the aphids Meadowsweet aphid occurs for more than 10 generations in 1 year, and overwinters with eggs next to the buds of branches, branches and jujube envy or bark crevices, etc., and the number of eggs in the wrinkles and scales of 2 or 3-year-old branches is more. In the spring of the following year, the host begins to hatch as a godmother when it sprouts, and gathers on the back of the leaves of the new shoots, young shoots, and new leaves to begin to be harmed, and more than 10 stools of cherry blossoms can be viviparous aphids after patting, called dry females, parthenogenetic viviparous reproduction, and only the last 1 generation of the late autumn in the whole year is hermaphroditic. After the dry female, it produces winged and wingless offspring, and the winged type transfers and spreads.

The reproduction rate in the early stage was slow, and most of the phenthic viviparous aphids were produced, and the winged parthenogenetic viviparous aphids could be seen in late May. From June to July, the reproduction rate was significantly accelerated, the population density was significantly increased, and aphids were clustered on branches, leaf backs and shoots. When the rainfall is heavy from August to September, the population density will decrease significantly, and the female and male sexual aphids will begin to be produced in October, and the tail will be mated and eggs will be laid for wintering.

Control of aphids: The hatred of aphids is deep into the bones, and the first time I used two poisons to kill all the aphids, the beneficial insects ran away from hunger, and I was never happy to take the medicine. There are many beneficial insects in his field, and there are fewer aphids than yours if they don't fight.

Fight aphids, only use a medicine that does not kill beneficial insects, do not kill the aphids every time, the beneficial insects have food to eat, and will never be flooded. Kill aphids in cool weather with Gaochang (imidacloprid) 6000 times. Hot weather with beaten down (acetamiprid) 6000 times.

Don't kill natural enemies, the effect is great. The crazy flood of aphid swarms is used in Gaochang, knocked down or cleared 3,000 times. There is a garden of wheat fields nearby, June|There will be no need to kill aphids in the future.

As soon as the wheat is harvested, the beneficial insects sweep away the aphids in only three days. In addition, try to make the orchard less autumnal, less tender, and less aphids. Hitting the top of the strip in time is also a way to reduce tenderness.
