For plums, it is very easy to be infected with a pest called heartworm during the growth process, this pest is the most serious pest that harms plum fruit, if left unchecked, the fruit damage rate of plums will be as high as about 90%, and the plums infected with heartworms can not continue to grow and develop, and will fall, affecting the quality and yield of plums. In the prevention and control of this plum heartworm, it should be reasonably sprayed with pesticides.

If it is in the peak adult and oviposition period of heart-eating insects, you can choose to spray dichlorvos, malathion, trichlorfon and other agents, but when spraying pesticides, you should pay attention to the reasonable concentration. In addition to spraying pesticides reasonably for control, it is also necessary to sweep all the fruits that fall from plums in a reasonable time, so that the chance of infection with pests and diseases in the second year will be reduced.

Plum heartworm should be controlled ten days after flowering, sprayed with high-efficiency and low-toxicity pesticides such as cyhalothrin and imidacloprid, sprayed again every ten days or so, sprayed once a month after that, and stopped spraying one month before harvesting.

If it is in the peak adult and oviposition period of heart-eating insects, you can use dichlorvos, malathion, trichlorfon and other agents for control, and you must pay attention to the reasonable concentration when spraying the pesticides.

Second, plum heartworms have flavor and phototaxis, and can be trapped, such as sugar:wine:vinegar:

Water = 1:1:2:

10 preparation, then add an appropriate amount of trichlorfon to trap the adults. Another example is to trap adult insects with insecticidal lamps. Thirdly, attention should be paid to the observation of the incubation period of each generation of heart-eating insects in Li Yuan for prevention and control.

Commonly used pesticides are ,..

Fruit tree heart-eating insects, pesticides to prevent the mainstay, after flowering to inject systemic insecticides.

Solid chair planting, at the earliest time when it begins to sprout, it should be beaten with dimethoate, so that it will kill insects.

After the plum tree falls flower, it can be sprinkled on the ground under the canopy, focusing on the radius of 1 meter around the trunk, poisoning the adults, and spraying about 25% of the parathion microcapsules. In the plum heartworm egg peak to the early stage of larval hatching. If conditions permit, black light and sweet and sour liquid can be used to trap and kill adult insects.

The availability of attractants was used to detect and report the occurrence dynamics of adult insects, and to guide the control of pesticides on trees. Plum tree diseases mainly include bacterial perforation, two-wheel pattern disease, brown spot, powdery mildew, and diseases can be sprayed once in late April or early May, and then sprayed twice to 3 times every half month. In the event of bacterial perforation, the leaves can be sprayed with 3000 times of 72% agricultural streptomycin soluble powder.

In 6 and 7 months, you can spray 1500 times of deltamethrin plus 1500 times of dimethoate oxymethoate, and spray four times in a row once a month. aqui te amo。

Summary. Hello, if it is in the peak adult and oviposition period of heart-eating insects, you can choose to spray dichlorvos, malathion, trichlorfon and other agents, but when spraying pesticides, you should pay attention to the reasonable concentration.

Hello, I am inquiring for you here, please wait a while, I will reply to you immediately Hello, I am happy to answer for you: pesticide such as phosphine EC and dimethoate EC for plum heart-eating insects.

Hello, if it is in the peak adult and oviposition period of the heartworm, you can choose to spray dichlorvos, malathion, trichlorfon and other drugs, but when spraying the agent, you should pay attention to the concentration and concealment is reasonable.

Is there anything else you need to consult? You can pay attention to the teacher's number, so that if you don't understand it in the future, you can ask the teacher directly. I hope the above is helpful to you If you are satisfied with me, please give it a thumbs up

How many times is trichlorfon as good? Does the young fruit have a response?

Dear, please wait a moment.

Hello, with 90% trichlorfon 800 times liquid, there is no effect on young fruits.

Thank you. You're welcome, that's the <> I should do

1) Before the overwintering generation of adults emerge, that is, after the plum tree falls flower, the focus of spraying on the ground under the canopy is within a radius of 1 meter around the trunk, poisoning the adult insects, and 25% parathion microcapsules can be sprayed per mu kilogram, and 50 90 times of water is added. It can also be used with 50% Diyanon, 20% pyrethroid, dimetrical emulsifiable concentrate, etc., which have good effects per kilogram per mu. If the agent lacks 6 10 cm thick soil to pat firmly, so that the adult can not be unearthed, the soil should be withdrawn in time after the feathering is completed to prevent the fruit tree from turning its roots.

2) From the peak of eggs to the early stage of larval hatching, the pesticides should be applied on the peach heartworm tree.

3) If conditions permit, black light and sweet and sour liquid can be used to trap and kill adults. The availability of attractants was used to detect and report the occurrence dynamics of adult insects, and to guide the control of pesticides on trees.

Hello dear, plum insect pests mainly include heartworms, red spiders, leaf rollers, stinging moths, etc., insect pests can be sprayed to kill pine borer 1000 times liquid or 40% dimethoate 1500 times liquid control. The preparation method of fruit vinegar is as follows: 1 part of the fruit, 1 part of vinegar, 2 parts of sugar, and water.

In the orchard, according to the standard of hanging 6-8 beer bottles per mu, hang the beer bottles at a height of about 10 meters from the ground, catch 2 or 3 live white star beetle adults and put them into the beer bottles, which will lead other adults to fly into the bottle.

Summary. For the control of plum heartworm, effective pesticides should be used, such as Bayer Chlorothalonil (Bayer Baccillus thuringiensis), Bayer Bacillus thuringiensis (Bayer Bacillus thuringiensis kurstaki), ciprofloxacin (Bayer cyromazine) and so on. These pesticides can effectively kill plum heartworms, but the dosage should be well controlled to avoid causing harm to the plant.

At the same time, attention should also be paid to the control time, choose the morning or evening application, in order to prevent too strong sunlight, so that the pesticide loses its effectiveness.

Ground application. Before the emergence of the overwintering generation of adults (after flowering), spray 75% phoxanthion emulsifiable concentrate kilograms per mu, or 500 times of 40% dimethoate emulsifiable concentrate in the tree disk, and rake it evenly with a rake after spraying, so that the medicinal soil is mixed and raised. At the end of flowering, Sui Ming can spray the first medicine when the small fruit has the size of a wheat grain, and use dichlorvos, enemy killing, quick killing Ding, and Lai Fu Ling, spray once every 7-10 days, and the effect is very good.

Biological control can be used for sub-canopy soil treatment, such as Beauveria bassiana, or for insect control by placing chicks in the orchard. Always maintain the hygiene of the garden and sweep the fallen fruits to reduce the source of insects in the next year. In addition, it is best for fruit farmers in a region to carry out unified control, which is an important factor for Fenghan to determine the quality of the control effect.

<> plum heartworm is a common insect pest in the process of plum tree growth, which seriously affects the quality of fruits. What pesticides are used to control plum heartworms?

Pesticide pesticides such as phosphine emulsifiable concentrate, dimethoate emulsifiable concentrate, permethrin, acitretin and emectin salt, chlorpyrifos and other pesticides are used for the control of plum heartworms. The spraying time is selected when the plum flowering period ends and begins to bear fruit, and it can be sprayed directly on the fruit, and attention should be paid to controlling the dose of medicine to avoid pesticide damage. The overwintering adults are dressed in the hole of the plum tree after falling flowers, and sprinkle the medicine on the ground under the canopy, paying attention to the radius of 1 meter around the trunk.
