Is it true that the pests and diseases that must be recognized in raising flowers often occur, so

It is true that there will be many pests in raising flowers, as well as environmental factors, which will affect the growth of flowers, so you must learn to maintain them.

Powdery mildew is very common in the family to raise flowers, such as we raise the moon season triangle plum and the like, these green leafy plants are most likely to occur in the vigorous growth season.

To raise flowers at home, you should choose some ones with a relatively low planting difficulty coefficient, fewer pests and diseases, and it is not difficult to take care of, and it is not troublesome. At the same time, you should also choose flowers that have less fallen leaves and occupy less land.

The first type, the triangular plum. Triangle plum is very easy to feed, basically does not need to be taken care of, and is relatively drought tolerant.

The second is roses. Roses have few pests and diseases and are ornamental, a small pot is enough, and some varieties are edible.

The third species, daffodils. Daffodils are also very few pests and diseases, but they need to be changed regularly.

Fourth, the sky is full of stars. The sky is full of stars, and it is also beautiful to make dried flowers.

There are relatively few pests and diseases of blue snowflake, generally speaking, its disease resistance is very strong, and there are few pests to disturb it, so the right pests and diseases can be considered less in the maintenance, but it can not be completely ignored, if there are pests and diseases, it must be prevented and controlled in time.

Cultivation methods and precautions for blue snowflakes.

1. Temperature. Blue snowflake is a relatively heat-loving plant, generally speaking, it will have growth stop below 7, it will have some cold damage below 5, and its leaves will all fall off above 0. The ideal growth temperature is between 15-28, and the high temperature above 35 also has a certain inhibitory effect on it. Therefore, in the maintenance of the country, except for the outdoor cultivation in the Lingnan area, which can not worry about any problems, other areas must enter the indoor cultivation in winter.

2. Illumination. Blue snowflake is a sun-loving plant and is slightly shade-tolerant, so it can be exposed to light at other times except at noon in the hot summer. In a shady or semi-shady environment, it can bloom normally, but the flower color will become dull and the amount of flowers will be reduced.

3. Moisture. Blue snowflakes are slightly drought tolerant in terms of water requirements, so don't water too much during the maintenance process, and do it dry and water thoroughly.

Fourth, fertilization. In the maintenance of blue snowflake, it can grow normally by giving it a thin water-soluble fertilizer of Vosch leaves every half a month during the growth period. It is not a particularly fertilizing plant, so it is a flower that is particularly easy to nourish and can easily achieve flowering effect.

A layer of white powder appears on the back or both sides of the leaf.

A gray mold layer is visible on the plants under wet conditions.

Near-circular lesions with light brown or grayish white in the middle and purplish-brown or dark brown at the edges. The lesions can be extended, and there are small black spots on the lesions in the later stages, and round or nearly round light brown spots can also be produced on the stems, and the lesions are mostly sunken.

When the seedlings have a certain degree of lignification, they are infected with pathogens, and the seedlings stand upright and die.

The leaves are yellowed and the shoots are wilted, which often induces coal stain disease.

The leaves lose green, showing dense and fine gray-yellow or patches, or the leaves are curled and shriveled, and in severe cases, the whole leaves are scorched and yellowed like fire, and fall off.

It will cause leaf curling, shrinkage, deformity, stunted flower development, and even wilting and death, which will also induce coal pollution disease.

The leaves appear pale white spots, and when the damage is serious, the spots are patchy, or the epidermis is punctured, so that the branches wither.

Leaves or shoots are incomplete.

Grass ash potting method: Frequent sprinkling of plant ash on the surface of the pot can greatly reduce the incidence of gray mold in tulips, cyclamen and other flowers, and at the same time increase the absorption rate of potassium fertilizer by flowers, so that the flower branches are thick and colorful.

Vinegar wiping method: With 50 ml of vinegar, soak the cotton ball in vinegar and gently wipe it on the flower stems and leaves, which can not only eliminate scale insects, but also make the leaves that have been damaged by scale insects turn green and bright.

Alcohol rubbing: Gently and repeatedly wiping the diseased leaves with scale insects with 75% alcohol can completely kill the larvae that are invisible to the naked eye.

Baking soda spraying method: spraying the damaged plants with a concentrated baking soda solution can control powdery mildew of more than 80% for flowers such as moon, chrysanthemum, impatiens, melon leaf chrysanthemum, etc.

1. Aphids: hibiscus, peach, hibiscus, hibiscus, yueji, honeysuckle, etc. are all susceptible to aphids. As the temperature rises, so do the number of aphids. The prevention and control methods are as follows:

1) 40% dimethoate or more or 50% imidothion water 1200-1500 times after spraying.

2) A small amount of potted flowers can also be sprayed with 70-100 times of neutral laundry detergent.

2. Red spider: the harm to jasmine, fusang, bamboo, yueji, dahlia, etc. from early April. The prevention and control methods are as follows:

1) It can be sprayed with 1000 times of rapid culling.

2) A small amount of potted flowers should be washed with tap water to the front and back of the leaves, or sprayed and dipped in 100-150 times of the batter water that has been boiled and cooled, and then rinsed with water once after a day or two, which can receive obvious results.

3. Scale insects: Most of the scale insects on succulents, magnolias, yueji, boxwood, and tung begin to hatch from mid-April to mid-to-late May. The prevention and control methods are as follows:

1) Gently brush off the worm body before it hatches.

2) Spray 1000-1500 times of 40% dimethoate during the larval hatching period.

3) Mix liquor with water in a ratio of 1:2. When treating insects, water the surface layer of the potting soil thoroughly. Scale insects begin to move at room temperature 7 in spring. It can be watered once in mid-April, and then every half a month or so, and it is effective for 4 consecutive times.

4) Use 50 ml of vinegar (rice vinegar), soak the small cotton ball in vinegar, and gently rub the wet cotton ball on the stems and leaves of the damaged flowers and trees, and then wipe off the scale insects to kill. 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.

5) Gently and repeatedly wipe the diseased plant with alcohol to get rid of scale insects, and it can be very clean and thorough. 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.

4. Blight: When the temperature reaches 20, newly sown flowers, saplings and some flowers that are prone to rot roots are very prone to blight when the soil moisture is high. The prevention and control methods are as follows:

1) Before sowing, each seedling was evenly mixed with 70% quintozenene kg in the soil.

2) Control watering at the seedling stage and do not make the soil too wet.

3) At the beginning of the disease, water 1% ferrous sulfate or 200-400 times 50% ammonium dyssen solution, and water 2-4 kg of potion per square meter.

5. Rust: Rust is invaded when the rose is budding. The prevention and control methods are as follows:

1) When the rose germinates, the yellow disease buds that germinate first should be removed and burned in time to eliminate the source of infectious diseases.

2) Spray 15% powder rust 700-1000 times in the initial infringement stage.

6. Powdery mildew: Powdery mildew and impatiens powdery mildew and other flower powdery mildew mostly occur in May and June, and it is easy to cause symptoms such as yellow leaves, dead leaves, and bent young shoots in summer. The prevention and control methods are as follows:

1) Pay attention to the ventilation and light transmission of flowers.

2) Apply less nitrogen fertilizer and more phosphorus and potassium fertilizer.

3) Spray 15% powder rust 700-1000 times liquid during the initial dyeing period.

We can go to the florist to buy some corresponding pesticides and apply the corresponding dosage according to the instructions of professionals and the specific conditions of pests and diseases in the home. This not only kills pests and diseases, but also prevents flowers from dying due to over-application.

Water control, increase environmental ventilation, reduce ambient temperature, spray drugs in time, and let it be exposed to sunlight, so that pests can be prevented from occurring.

Growing flowers at home is more likely to breed pests and diseases because the indoor ventilation is poor and the sunlight does not shine in. The flowers should be moved to an outdoor balcony to be maintained in a ventilated and well-lit place, and special pesticides should be used to kill insects.

1.Pest control method: spray 40% dimethoate 1500 times, in addition to scale insects, other pests can also be sprayed percent.

Cypermethrin 3000 times solution, the control of red spider can be sprayed with 20% dicofol 1000 times. 2. Leaf-eating pest control methods: manually eliminate overwintering insect seedlings, and spray 90% trichlorfon or 50% octathion 1000 times liquid in the initial incubation period of larvae.

You can burn some dead branches and leaves to get plant ash, or buy it directly from the Internet, and then dig a few holes in the side of the pot, and then sprinkle the prepared plant ash into the hole, and then fill the hole with soil, and then hand over some water, which can effectively ** powdery mildew of plants.

1. Pest control method: spray 1500 times of 40% dimethoate.

2. Leaf-eating pest control methods: manually eliminate overwintering insect cocoons, and spray 90% trichlorfon or 50% octathion 1000 times liquid during the initial hatching period of larvae.

Depending on the situation, what kind of insect pest is used in what way.

Household flower pests and diseases, prevention first, treatment as a supplement, more observation, early prevention and early detection.
