What is the white stuff growing on the leaves and flowers? How to remove it

1. What is the white thing?

If white stuff appears on the leaves of the flowers you grow, you can pick them apart and take a look. If there are no insects inside, they may be infected with powdery mildew, which is caused by bacterial infection. There are many factors for this situation. If the water and fertilizer are not applied correctly and the light is not well controlled, it will cause this disease. At first, it is just irregular small spots, which will slowly expand later.

If you pick it open and see small bugs inside, it means it is infected with pests, namely beetles. They absorb the juice in the leaves, which will cause the leaves to fall over time.

2. How to remove

1. If it is powdery mildew, you can spray some carbendazim or other antibacterial drugs, and cooperate with timely ventilation and exposure to sunlight, and it will be cured after a period of time. This disease is easy to occur when the seasons change, so you can pay more attention to it at that time.

2. If insect pests occur, you can spray some insecticides, such as cypermethrin, imidacloprid, etc., and spray them with water. You can also use a brush dipped in salt water or soapy water, and brush from the bottom of the leaves downwards. Be sure to brush several times to prevent missing any, and then place it in a ventilated place.
