The white spot insects on the Milan flower branches cannot be removed manually, what method is good?

Because you didn't provide **, I can only guess from your description that it could be.

Scale insects. Scale insects are the most common pests on flowers and fruit trees, often clustering on branches, leaves, and fruits, sucking plant sap for survival, and in severe cases, they will cause branch wilting or the whole plant die. The secretion of scale insects can also induce coal stain disease, which is extremely harmful.

The affected flowers include Milan, jasmine, camellia, and smile.

The methods of prevention and control are: it may be more troublesome but it will definitely be effective!

Mix liquor with water in a ratio of 1:2

When treating insects, water the surface layer of the potting soil thoroughly. Scale insects at room temperature in the spring7

, start the activity. Available in 4

Water once in the middle of the month, and then every half month or so thereafter, for 4 consecutive years

times effective. Use vinegar (rice vinegar) 50

ml, put the small cotton ball into vinegar and soak it, and gently rub it on the stems and leaves of the affected flowers and trees with a wet cotton ball to wipe off and kill the scale insects. This method is convenient and safe, which can not only achieve the purpose of insect control, but also make the damaged leaves green and shiny again.

Gently and repeatedly rubbing the diseased plant with alcohol can remove the scale insects, and it can be removed very cleanly and thoroughly. If you wipe the orchid leaves with alcohol, not only can you get rid of the scale insects, but also the larvae that are not clear to the naked eye, and they are completely killed.

Press with diesel, laundry detergent, water.

The proportion is adjusted to the mother liquor, and the mother liquor contains 60% at this time

It is milk-like, diluted with water and contains 30% oil

After the solution, carefully spray the scale insects on Milan, kumquat, and cycads. After one week, most of the scale insects changed from fresh orange to shriveled state, indicating that this method has a good control effect on scale insects. Depending on the occurrence of scale insects, spray at the peak of nymphs.

Therefore, most nymphs hatch for a short time, the body surface has not yet secreted wax, and the shell has not yet formed, and it is still easy to kill with medication. Spray once every 7-10 days, 2-3 times in a row. It can be sprayed with 40% dimethoate 1000 times, or 50% malathion 1500 times, or 255 imithion 1000 times, or 50% dichlorvos 1000 times, or deltamethrin 3000 times.

Maybe a little verbose.

But if it's really this bug.

Introduce how to kill orchid scale insects.

1. Aphid control: spray plants with cigarette butts or pepper water. Spray 800 times the solution of aphidin.

If the quantity is small, it can be removed by manual brushing or by brushing the fire. Other control measures refer to the fact that the moon is quarterly. 2. Beetle, control:

Spray with 500 times the liquid of mediator l. When the quantity is small, the brush can be brushed off manually. Other control measures can be referred to Monarch Orchid.

3. Red spider.

Control: Spray the plants with dichlorvos 1000 times pinaculture solution or dimethoate 2000 times solution. For other control measures, please refer to Begonia.

There is no fermentation and rotting with nutrient soil, and there are more pests and diseases in the soil, and there are more pests and diseases in the animal manure, crop straw, and scraps, and if they are directly applied to the soil, they will spread, breed, and hatch in the soil, endangering the growth of crops, and outbreaks of pests and diseases.

People who have been raising flowers for a long time often encounter the situation of potting insects, and I will briefly introduce a few methods below:

1. Precautionary Act. Before potting the potted flowers, put the potting soil into a larger old food bag, pour boiling water, tie the bag tightly, expose it to the sun for a day, and then spread it out and dry it to use, which can play a role in killing insect eggs.

2. Chemical method. Long-term dampness in the potting soil causes insect pests, insecticides can be purchased, sprayed to kill insects, and indoor potted plants should be avoided.

3. Change the living environment of pests, move the flower pot to a dry and ventilated place, bask in the sun, pay attention to timely watering, and shade-loving flowers, such as orchids and bamboos, should cover the plants and prevent sunburn leaves.

Fourth, replace the potting soil. After changing the soil, it is necessary to pay attention to shading and maintenance for a period of time before it can be transferred to normal cultivation.

Summary: It is a very common phenomenon to grow insects in the soil of planting flowers, and there are many reasons for the generation, the most important reason is that the soil is not treated well, and many germs, eggs and pests are living or overwintering in the soil. So the best way is to change the pot, that is, to change the soil.

If you haven't started potting yet, sanitize the soil before potting.

The ** method of growing white spots on the branches of Milanese flowers is as follows:

1. Cut off the diseased old leaves.

2. It seems that you can also spray the foliage with pesticides for powdery mildew in proportion to water, for example: irrigate the roots with carbendazim 1000 times.

3. Pay attention to the water, fertilizer and ventilation conditions of Milan planting, and control the humidity.
