How to treat and prevent powdery mildew

1. How to treat powdery mildew

1. How to identify: Powdery mildew is just as its name suggests. When it is infected, the leaves of the plant will be covered with white powder, which will not only affect the appearance of the plant, but also the growth of the plant. When the disease is serious, a large number of white spots will appear on the leaves of the plant.

2. Chemical control: When the disease is relatively minor, you can use a soft cloth dipped in water to wipe off the white powder. When the disease is serious, cut off the leaves that are seriously affected, and spray the flowers with triadimefon and fenadone alternately. After spraying, pay attention to ventilation of the maintenance environment.

3. Folk remedies for prevention and control: Flower lovers who do not want to use pesticides can use an ear pick to scoop a spoonful of baking soda, add 50 ml of clean water, and spray the diseased leaves once every two days. Wait for an hour after spraying, and then spray again with clean water to prevent the high concentration of baking soda from burning the seedlings.

1. Ventilate frequently: Not only powdery mildew, but for most diseases, a poorly ventilated maintenance environment is the main cause of plant disease. Therefore, when we grow flowers at home, we must open windows frequently for ventilation to prevent the occurrence of diseases and pests.

2. Carbendazim: Spring and summer are the peak seasons for powdery mildew. You can spray the plants with carbendazim once every half a month for prevention. If you don’t have carbendazim, you can also spray the plants with onion water (chopped onions soaked in water) to prevent the occurrence of the disease.
