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.
-
You can play a drug like 670, the effect is very good, and after you hit it, you can quickly eliminate the virus, and the reset will also be eliminated, so such a pesticide can be said to be very good, and then you pay attention to the proportion of this drug.

There are enylpymetrozine, pymetro, clothianidin, thiamethoxam, and penetrants such as silicones, which are conducive to enhancing the control effect.
-
Matrine, imidacloprid, pymetrozine, acetamiprid, chlorpyrifos, cypermethrin, etc., that kind of medicine will do.

Zanthoxylum pepper with insecticides, such as dimethoate 1000 times;In particular, the effect of 40% speed culling 800-1000 times is good, and the critical period must be grasped, in 4-5 months, the incubation period and high incidence period of pests and mites are controlled with 25% mite net 500 times and 73% gram mite 3000 times solutionor oxidize dimethoate 1000 times with systemic insecticides;40% speed culling 800-1000 times.
Biological control: Sichuan scleroderm swollen-legged wasp is the natural enemy of P. zanthoxylum, in July sunny day, according to the standard of 5-10 Sichuan scleroderm swollen-legged wasps per infected plant, the natural enemy is placed on the affected plant. Practice has proved that the application of Sichuan scleroderma swollen-legged wasp has a good effect on the control of Prickly prunum tiger longhorn.
In winter and spring, use a straw or brush to wipe out the overwintering females on the trunk or branches and the male pupae in the cocoon.

Aphids to prickly pepper to control pesticides, what kind of medicine is effective?
The effective agents for the prevention and control of Zanthoxylum pepper tree aphids are pyritrazine, pymetro, thiamethoxam, clothianidin, thiamethoxam, pymetrozine, acetamiprid, furophorid, etc., fast-acting agents have pyrethroid agents and chlorpyrifos, etc., which can generally be used together, and can also be added to the penetrant agent such as Hezhiyu silicone, which is conducive to enhancing the control effect.

In order to control aphid pests and insect pests of Zanthoxylum bungeanum pepper, it is necessary to spray a new high-lipid film during its flower bud period, as well as Zanthoxylum zanthoxylum pepper, and spray pyrethroid and chlorpyrifos during the fruit growth period. In the process of daily maintenance, it can also be ventilated for Zanthoxylum to maintain air circulation in the environment, and it can also strictly control the moisture for Zanthoxylum to avoid too humid environment.
Aphids are a kind of insect pest that often occurs in Zanthoxylum, it sucks the juice on the young branches and young leaves of Zanthoxylum for life, and gradually causes the branches and leaves to curl, if the disease develops further, it will cause the phenomenon of Zanthoxylum pepper falling flowers and fruits, so the harm is very serious.
For the occurrence of pepper aphids, because this insect pest is relatively difficult to treat, the focus is on prevention. First of all, nicotinic pesticides such as imidacloprid and thiamethoxam can be used to spray during the growth of Zanthoxylum bungeanum pepper, and the effect is very obvious, which can effectively kill Zanthoxylum pepper aphids.
When the pepper enters the flower bud period, it can be sprayed once a month with a new high-fat film to prevent insect infestation. In addition, in order to improve the pollination rate of Zanthoxylum bungeanum flowers, Zhuangtilin can be applied to prevent flower fall. Finally, during the fruiting period, pyrethroid agents and chlorpyrifos can be sprayed.
Everything in the world has natural enemies, so the natural enemy of the pepper aphid is the seven-star ladybug, when the insect infestation can be introduced into the seven-star ladybug and aphid-eating fly, in addition to artificial stocking, which can effectively kill the aphid, play a positive preventive role, so that the pepper grows healthier and the fruit is fuller.

Dear, thank you for your patience, I am your ** teacher, take your questions about you: Zanthoxylum pepper aphids You can use pyrethroid agents and chlorpyrifos and other agents to work best. In order to control aphids and insect pests for Zanthoxylum bungeanum pepper, it is necessary to spray a new high-fat film and Zanthoxylum pepper during its bud period, and spray pyrethroid and chlorpyrifos and other agents during the fruit growth period.
In the process of daily maintenance, you can also ventilate and breathe for peppercorns, maintain air circulation in the environment, and also strictly control the moisture for Huahong pepper to avoid excessive humidity in the demolition of Huanxiao, thank you for your trust, the above is all my reply, I hope it can help you.

<> can control the aphids of Zanthoxylum pepper trees are pymetrozine, pymetro, thiamethoxam, clothianidin, thiamethoxam, pymetrozine, acetamiprid, dinotefuran, etc., and the fast-acting agents are pyrethroid agents and chlorpyrifos, etc., which can be used together, or add penetrants such as silicones. Aphids have a large range, generally concentrated in temperate regions, and because species diversity is much lower in the tropics than in temperate zones, aphids can migrate over long distances. Aphids are also harmed by bacteria, fungi, viruses, and sometimes weather, such as rainfall, temperature, wind, etc.
1. What kind of drugs can be used for aphids on pepper trees?
1. The agents for the prevention and control of aphids in Zanthoxylum pepper trees include pyritrazine, pymetro, thiamethoxam, pymetrozine, clothianidin, thiamethoxam, pymetrozine, acetamiprid, dinotefuran, etc., and the fast-acting agents mainly include pyrethroid agents and chlorpyrifos, which can be used together, and penetrants such as silicones can also be added, which is conducive to enhancing the control effect. For pepper trees with a relatively large number of aphids, it is advisable to apply pesticides to the leaves and drip water.
2. The distribution range of aphids is very wide, mainly concentrated in temperate regions, and because the diversity of species will be much lower in the tropics than in temperate zones, aphids can migrate remotely. Generally spreading in the form of drifting in the wind, the body of the aphid is very soft, so it has a large number of insect predators.
3. Aphids are often infected by bacteria, fungi and viruses, and sometimes they are easily affected by the weather, such as rainfall, temperature, wind, etc. There are many natural enemies of aphids, mainly aphid-eating flies, parasitic wasps, ladybugs, aphid-eating gall mosquitoes, aphid lions, crab spiders, lacewings, etc., these insects have a strong inhibitory effect on aphids.
2. What are the hazards of aphids?
1. The performance of aphids to different plants is different, and vegetable aphids generally appear on the back of vegetable leaves or on the young leaves, which will make the leaves curled, deformed, and the whole plant is small. If it is a bulb vegetable, it will affect its core, resulting in loss and yield reduction. If the vegetables are attacked by aphids, they will not produce seeds and flowers, and in addition to this, they will also spread viral diseases.
This is often the case in warm areas or in greenhouses, especially in parts north of the Yangtze River.
2. The harm of wheat aphids mainly includes indirect and direct aspects, and the indirect harm is that aphids harm wheat and transmit wheat virus diseases at the same time, which will bring greater harm, and may appear lodging and yield reduction. The direct damage is that the aphids absorb the sap on the wheat stalks, leaves, and tender wheat ears to form certain dead spots, which affects the quality and yield of wheat. After absorbing the sap of wheat leaves, photosynthesis will be weakened, resulting in a large area of yellowing.
1. Remove the dead branches and fallen leaves, and cut off the diseased and insect branches. >>>More
3 May can be carried out, March is the spring of the recovery of all things, then for these insects also begin to wake up actively, bringing damage to crops, so it is best to fight these insects in spring. If you don't hit in this season, then our crops will be seriously harmed, which will directly affect the growth of these crops, so for some growers at this time do not carry out insecticide, and they will find it more and more difficult to treat in the later stage, after all, they will definitely lay eggs before it lays eggs, so it is more convenient. <> >>>More
