This article will introduce in detail six common pests and diseases of household flowers and their prevention and control methods, hoping to help flower lovers protect their beloved flowers and let them grow healthily and bloom beautifully.

1. Aphids

Aphids are small green-yellow insects that harm almost all flowers and trees. They often gather on the young branches and leaves of flowers and feed on the sap of the plants. The leaves of flowers infested by aphids will shrink and curl, and galls may form. In severe cases, the growth of flowers will be stunted or even wither.
Prevention and treatment methods:
Physical control: Aphids in small numbers can be gently wiped with a cotton swab dipped in water or soapy water.
Chemical control: Use imidacloprid pesticide or dimethoate emulsion for spraying. Dilute and use according to the instructions to avoid damage to flowers.
Homemade natural insect repellent: Mash garlic, soak it in water for 24 hours, and then spray it on the surface of plants to effectively repel aphids.

2. Scale Insects

Scale insects like to "visit" a variety of flowers, such as bergamot, camellia, rose, etc. They often gather on the branches and leaves of plants, penetrate into the plant tissues through their mouthparts to suck juice, causing damage to the growth of the plants. In severe cases, it will affect the ornamental value of flowers and even cause the death of flowers.
Prevention and treatment methods:
Manual removal: Small numbers of scale insects can be picked to death or brushed off with a toothpick or an old toothbrush.

Chemical control: Use 50% chlorpyrifos oil or other pesticides containing organic phosphorus ingredients for spraying. Also dilute and use according to the instructions.
Watering with white wine or alcohol: If the scale insects have grown to a certain size, you can use white wine or 75% alcohol to water or wipe the affected plants.

3. Red spider

Red spider mites are tiny and difficult to see with the naked eye. They can produce more than a dozen generations a year. They mainly suck the sap of the plant. When the damage is serious, the leaves will show dense and tiny gray-yellow spots or patches, and the leaves will gradually turn yellow and fall off. Red spider mites will also weave some webs on the back of the leaves, affecting the normal photosynthesis of the plant, and in severe cases, they can cause the death of the plant.
Prevention and treatment methods:
Physical prevention: Use a cotton swab soaked in alcohol to carefully wipe the area where the red spiders grow, killing them through the bactericidal effect of alcohol.
Chemical control: Use pesticides such as cypermethrin for spraying. Be sure to dilute and use according to the instructions.
Improve the environment: increase ventilation, maintain appropriate temperature and humidity, and reduce the breeding of red spiders.

4. Little Black Fly

If the soil of your potted plants is often damp or the environment is not ventilated, it is easy for black flies to breed. They themselves are not very harmful to the plants, but they reproduce very quickly and the dense appearance makes people's scalps numb. More importantly, the appearance of black flies often means that the soil is too humid, which can easily cause other diseases and pests.
Prevention and treatment methods:
Keep the soil dry: remove stagnant water around it in time to avoid over-wetting of the soil.
Improve ventilation environment: strengthen ventilation, maintain air circulation, and reduce the breeding of small black flies.
Physical control: Sprinkle some fine sand or diatomaceous earth on the soil surface to effectively reduce the breeding of small black flies.
Mosquito-repellent coils can be soaked in water and watered: Mosquito-repellent coils can be soaked in water and watered, which can play a certain role in preventing and controlling small black flies.

5. Powdery mildew

Powdery mildew is a common disease on flowers, caused by fungal infection. It is usually more active during the rainy season, with white spots appearing on the leaves at first, then slowly covering the entire leaf until it turns gray. If measures are not taken in time, powdery mildew will slowly spread to the entire plant, seriously affecting the ornamental value of the flowers.
Prevention and treatment methods:
Improve ventilation and lighting: Keep the plant's growth environment well ventilated and well-lit to reduce the occurrence of powdery mildew.

Clean up diseased leaves promptly: If you find powdery mildew infection, cut off the diseased leaves in time to prevent the spread of the disease.
Spraying agent: Use thiophanate-methyl or thiophanate-methyl solution for spraying, dilute and use according to the instructions.
Enhance plant disease resistance: Reasonable fertilization and watering can enhance the disease resistance of flowers and reduce the occurrence of powdery mildew.

Prevention of pests and diseases

When growing flowers at home, the prevention and control of pests and diseases is the key to maintaining the healthy growth of flowers. Once pests and diseases are discovered, measures should be taken as soon as possible to prevent them from spreading.
