Malathion is not only used in rice, wheat and cotton, but also used in vegetables, fruit trees, tea, and warehouse insect control because of its low toxicity and short residual effect. It mainly controls rice planthoppers, rice leafhoppers, cotton aphids, cotton red spiders, wheat armyworms, pea elephants, soybean heartworms, fruit tree red spiders, aphids, mealybug shellworms, nest moths, vegetable yellow-striped jumping beetles, vegetable leaf insects, a variety of scales on tea trees, as well as mosquitoes, fly larvae and bed bugs.

Summary. Hello, I have seen your question and am sorting out the answer, please wait a while Oh Hibiscus peanut worms, what to do.

Hello, I've seen your question, I'm sorting out the answer, please wait a while Hello, I've seen your question, I'm now hand-hungry for you, but it takes a little time, please wait patiently, thank you

Hello dear, 1Artificial insecticide: When the number of aphids is small, you can pick it with a needle or use a brush with hair.

2.Spraying: After cutting off the infected branches and leaves on the hibiscus potted plant, spray dichlorvos or dimethoate emulsion.

3.Root prevention: Soak hibiscus seeds in a sent-bond permanganese hydrolysis solution before planting.

4.Precautions: Cut off the rotten roots of the hibiscus, dry it and replant it with soil.

It is hatched from the eggs of flying insects, and some insecticidal drugs are used;

They affect the growth of plants, last year my bamboo also grew, I used a clever trick to get it, method: liquor, the degree does not need to be very high, with tap water 1:2 ratio to stir well, like weekday watering, two or three times to get all the insects.

Be careful not to have too much of the wine, don't burn the flowers, it's not good to get drunk, ......

When insects are found, high-efficiency and low-toxicity pesticides should be sprayed in time to avoid larval growth and achieve a timely control effect.

Hibiscus is a common woody flower with high ornamental value and is often used in the decoration of home gardens. So, do you know the methods and techniques of hibiscus pest control? How do they control pests and diseases? Today, Bian Xiao will give you a detailed introduction to the relevant knowledge.

There are few pests and diseases in the growth process of hibiscus, and the main diseases are anthracnose, leaf blight and powdery mildew. The main pests are spider mites

Aphids, moths, noctuidae, beetles, etc. When pests and diseases occur, the town will cut off the branches of the pests and diseases, and choose safe, efficient and low-toxicity pesticides for spray control or trapping. It is necessary to pay attention to early prevention and control, avoid pesticides during flowering and harvesting, and ensure that the harvested hibiscus flowers are not polluted by pesticides.

This hibiscus flower is susceptible to mites, aphids, and longhorns. Pay attention to early prevention and control. When pests occur, some high-efficiency and low-toxicity pesticides, such as Uranus, carnosine, etc.

It should be used, and branches should be inspected regularly. If the harm of the longhorn beetle is discovered, the hole should be plugged in time and the moth should be culled again.

The common pests of hibiscus are mainly aphids, leaf rollers, inchworms, and stinging moths.

Aphids

When the aphids hatch in spring, spray 200 times of 80% dimethoate emulsion or 2000 times of 40% dimethoate to kill the aphids on the branches. For the formation of galls or aphids on trees in autumn, the concentration of pesticides should be increased appropriately.

Leaf-curling moth

When the larvae first hatch or fall to the ground in a curled leaf state, spray 50%.

1000 times of phosphine or 1000 times of 90% trichlorfon.

Inchworms

During the larval occurrence period, spray 1000 times of 90% trichlorfon or 40% dimethoate to kill larvae and protect and release parasitic wasps. Stinging moths use picking, tapping, digging and other methods to collect insect cocoons, and dig pits to bury them deeply, which can effectively reduce the density of insect populations. The small larvae of the stinging moth are multi-clustered and can be manually removed and eliminated; It can also take advantage of the phototaxis of its adult insects to set up black light traps, and the effect is very good.

1. Artificial insecticide: When the amount of aphids is small, you can pick it with a needle or brush with a brush. 2. Spraying agent:

After cutting off the infected branches and leaves on the hibiscus potted plant, spray dichlorvos or dimethoate emulsion. 3. Root prevention: soak hibiscus seeds in permanganese hydrolysis solution before planting.

4. Precautions: Cut off the rotten roots of the hibiscus, dry it and change the soil and replant.

1. Artificial insecticide

Aphids are one of the common insect pests of hibiscus potted plants, when the number of insects is small, you can use a fine needle to pick out the pests, or brush them off with a brush tool, and then cut off the damaged branches and leaves, and apply plant ash to the wound to sterilize and disinfect.

2. Spraying agent:

If the hibiscus potted plant is accidentally infected with insect pests such as red spider and demoiselle, the infected branches and leaves should be cut off immediately, and then 40% dimethoate emulsion or 80% dichlorvos emulsifiable concentrate should be used to spray the pests, sterilize and disinfect, and then place the plants in a ventilated environment for maintenance.

3. Root cause prevention

Before planting, the hibiscus seeds can be soaked in potassium permanganate solution for more than 2 hours to fully absorb the solution, and then mixed with diluted carbendazim solution into the soil for disinfection, and then planted to reduce the probability of insect pests.

4. Precautions

If the hibiscus encounters serious insect infestation, it is necessary to remove the pot in time to check the roots, and cut off the rotten parts of the root system, apply the Bordeaux solution and put it in a ventilated place to dry, and change the soil and replant.

Dear, hello, happy to serve you When white flying insects appear on the hibiscus plant, you can use the flower protector to kill the insect, dilute the liquid with appropriate water, move the plant to an outdoor ventilated environment and then apply the pesticide. Or spray with drugs such as imidacloprid, cypermethrin, and avitamiprid, all of which have a definite effect. It should be noted that averidamidine is less toxic, but the taste is relatively large, and pets need to be isolated
