Cherry leaves are eaten by insects, what kind of medicine is used?

The medicine of cherries in each period is different, such as in the budding stage, you can use R. solanacearum and Diliwang silicone to irrigate the roots, which can promote the growth of the root system. So what is used in other periods? Let's take a look.

Embryonic stage

The medicine of cherries needs to be based on the growth of the tree, and the root irrigation should be carried out half a month before germination. Irrigate the roots with 200-fold dilution of R. solanacearum and 300-fold dilution of Diliwang silicone. It can effectively sterilize bacteria, and it can also promote the growth of the root system. Increase yields.

Spring bud stage

Spring is the budding stage of cherry trees and requires adequate nutrients. It is necessary to ensure the repair of the wound and reduce the occurrence of germs. At this time, you can spray 60 100 times of ulcer with silicone mixture on cherries, which can effectively repair wounds and replenish nutrients.

Flowering period

Before flowering, spray the agent, which can help flowering, at this time, the choice of agent can choose 300 500 times Liangguoan and silicone, and spray all the cherry trees. This can increase the bud sitting rate and sterilize.

Foliage period

When the leaves are spreading, you can spray them every 10 days with 300 times of Liangguoan, spray twice in a row, and add 600 times of the compound Wofengsu for the first time, which can effectively promote leaf development. It can also increase photosynthesis and make organic matter.

Fruit growth period

When the fruit grows, you can spray 300 500 times of Liangguoan, with silicone 10 15 days spray once, if the fruit growth is weak, you can add 600 times the compound of Wofengsu. Supplementing nutrients can also sterilize.

Late fruiting stage

After the fruit is picked, it is sterilized. At this time, it can be sprayed with 200 300 times of ulcer and 600 times of wofengsu silicone, which can effectively repair the wound, avoid the entry of bacteria, and can effectively kill bacteria.

DefoliationWhen the leaves are falling, you can spray 60 100 times of the mixture of ulcer and silicone to sterilize and repair the wound, which can avoid bacteria from invading fruit trees, and can also reduce the residual amount of bacteria, so as to better flower and fruit.

If you have planted one or two trees in your yard, then it is recommended that you catch insects with your hands; If you are planted with a large area of cherry trees and leaf curlers are common, then it is recommended that you buy a red-eyed bee card to release.

Cherry leaves can be sprayed with silicone and 300 times Liangguoan every 10 days, twice in a row, which can also increase photosynthesis and produce organic matter.

The symptoms of insect bites on cherry leaves are usually many small holes in the leaves or traces of gnawing on the spine, which is most likely caused by pests such as leaf aphids, leaf jumping insects, mealybugs, etc.

Here are a few things you can do:

1.Manual deworming. When pests are found in the ears of the leaves, they can be removed manually, which is the easiest and most natural method. Twist off the pest by hand or pick it off with a sharp object such as a bamboo stick, and then rinse the rock-deficient leaves with water. However, the effect may be limited, and it is difficult to completely remove the source of insects.

2.Chemical spraying. You can choose agents that are effective for pests, such as acetamiprid, permethrin, thiamcloprid, etc., and dilute them according to the drug instructions and spray them on the leaf surface to quickly exert their insecticidal effect. However, pay attention to safe use and observe the pollution-free picking period.

3.Biopesticide use. You can choose biopesticides that are safe for natural enemy insects, such as acetamiprid wettable powder, etc., which are safe for other beneficial insects by enhancing the plant's own immunity to achieve the purpose of controlling pests. The method of use is the same as that of chemical pesticides.

4.Fertilization conditioning. Proper management of nitrogen fertilizer and water fertilizer can enhance the growth potential and resistance of plants to pests and diseases. However, too much nitrogen fertilizer will produce weak young leaves, which will be more susceptible to pests. It needs to be balanced.

5.Eliminate hotbeds of pests and diseases. Regular weeding and pruning, removal of dead branches and leaves, can remove the breeding environment of pests and pathogens, and help pest control.

In addition to the above measures, biocontrol products can also be selected for prevention and control. However, harmless biological control methods, such as the introduction of natural enemies, have a long-lasting effect but require certain conditions. In short, it is necessary to use a variety of measures in a comprehensive manner, and at the same time strengthen tree management, so as to effectively curb the occurrence and spread of insect pests.

Summary. Insects that attack aphids include ladybugs, aphid-eating flies, parasitic wasps, aphid-eating gall mosquitoes, aphid lions, crab spiders, and lacewings.

Because it is allergic to organic pestine phosphine, some polyester pesticides can be used. The LG of DDV is non-collapsing. Imidacloprid, a very effective pesticide that kills sleepy stabbing and sucking mouthparts, can also be used.

What is the cause of the growth of honey worms on the trunk of the cherry tree, and what kind of medicine must be used?

You can use 1 bag of Shengnonsu (10 grams) + 1 stick (4 ml) of Nian Chenqing + 4 grams of imidacloprid (half a bag) + 50 grams of salt, add about 3-4 catties of water to spray and hold Shi. This mixture can be used alone to prevent insects, or it can be used to kill and sweep, and imidacloprid can be added to the above mixture at the same time to prevent insects. 2. Use local insecticides mixed with sannongin and salt to prevent insects.

I have to buy more than 100 trees to buy how much medicine, there is no actual definition, you can buy more, after all, you may need it later.

What is the cause of it, it looks like a honey worm Yes, will the tree die?

It's an aphid! Timely management is not much of a problem.

Insects that attack aphids include ladybugs, aphid-eating flies, parasitic wasps, aphid-eating gall mosquitoes, aphid lions, crab spiders, and lacewings.

Raising some natural predators will prevent the occurrence of aphids in large areas to a certain extent. You can't raise too many predators, otherwise they will flood.

Summary. Hello, cherries have red-necked longhorns, penetrated wing moths, mulberry white scales, and large green leafhoppers. The larvae of longhorn beetle are mainly harmed by larvae, and chlorpyrifos or kung fu pyrethrin can be injected into the wormhole with a syringe and then sealed the hole for control.

Scale insect damage is controlled with drugs such as libutrine or matrine or pymetrozine or thiamethine or thiazinone. Leafhoppers are controlled with drugs such as kung fu pyrethrin or deltamethrin or acitrin or emectin benzoate with high chlorine.

Hello, I have seen your question and am sorting out the answer, please wait a while Hello dear, cherries have red-necked longhorn beetles, penetrated wing moths, mulberry white scales, and large green leafhoppers. The larvae of the longhorn beetle are mainly harmed by larval silvershade insects, which can be controlled by injecting chlorpyrifos or kung fu pyrethrin into the wormhole with a syringe and then sealing the hole. Scale insects are harmed and controlled with drugs such as liverine or matrine, or pymetrozine or thiamethoxa, or thiazinone.

Leafhopper is controlled with drugs such as kung fu pyrethrin or deltamethrin or acitretin, or emamectin benzoate, and perchloride.

What medicine is used for the cherry trunk tossing upside down.

What does it mean to be upside down, haven't heard of it.

It's just worms, and they're withered.

I cut the branches, and the leaves have insect eyes.

What kind of medicine is used? 1. Agents for the prevention and control of scale insects (Mulberry scale, Korean ball scale, red wax scale, paramecium, etc.): stone sulfur mixture, engine oil emulsion, scale melting, phosphorus, rapid culling, speed scale, scale scale, aphid lice, imidacloprid, Chunfan is precious, Kangfuduo, Emilor, Gaida, acetamiprid, Nanbao, Mobilang, Haolabor, Anmin Le, Lesben, Youlede, thiazinone, etc.;

Is azoxystrobin, difenoconazole okay?

OK.

There are small insects in the cherry treetops, what medicine works well? The harmful larvae eat the branches, first eat vertically and horizontally under the cortex of the pests and diseases, and then bury into the xylem, penetrate deep into the center of the trunk, and accumulate sawdust-like insect feces outside the cavities, causing gum flow, and in severe cases, causing large branches and even the death of the whole plant.

Morphological characteristics (Fig. 40) The adult body is 28 to 37 mm long, black and shiny, and the anterior thorax and back are brownish-red. Antennae whip-shaped, 11 segments in total. The eggs are oblong, 3 4 mm long, the mature larvae are 50 mm long, yellowish-white, the head is small, the abdomen is large, and the nucleated foot is degenerate.

The pupal body is 36 mm long, and the fluorescent white is a naked pupa.

Habits occur in 2 to 3 years and 1 generation. The larvae overwinter in the trunk tunnels. In the spring, the overwintering larvae begin to damage after the sap flows.

4 June-month-old mature larvae pupate in the xylem with secretions, manure and sawdust. 6 In July, it becomes an adult worm, burrows out of the mating tail, lays eggs in the cracks of the trunk and thick branches, and hatches into larvae 10 days after laying eggs, and borers into the cortex. Always hazard within the branches.

You can water cherries in salt water for three to five minutes to repel insects. In short, the small insects of the cherry are the larvae of the Cherry Mosque and are harmless to humans. In order to avoid gnawing on the vibrating treetops, the vibrating falling method was used to kill the adults, and the 50% parathion-zinc emulsion was used 1500 2000 times during the injury period, and 600 groups of carbaryl wettable powder or 1000 times 50% phenytothion emulsion had a good control effect, and the treatment method was:

Leafhoppers kill adults and nymphs, trunk viscose, chemical tillage for cherry pests.

Everything we normally use is used. Dipping vinegar in vinegar is one of the things we use a lot. The main pests and diseases of cherry trees include blueberry white scales, stinging moths, peach-billed red beetles, beetles, heartworms, anthrax, and cherry leaves. It's hard**.

You can use clamphetamine to control the branches of the cherries while they are still green, while spraying weeds. When the fruit begins to change color, spray sugar, wine and vinegar on the tree. Medication control:

Apply 500 times 25% tebuconazole emulsion and 70% methyl tobuzine to the infected site. Fruit flies: harmful symptoms.

It is mainly harmful to cherry fruits.
