What should I do if there is something sticky on the flower leaves?

Scale insect infection: Scale insects mostly occur in spring. Before infection, we should take precautions, strengthen ventilation, control temperature and humidity to avoid infection. When found, cut off the leaves with pests in time, or brush off the pests with a brush. If there are many pests, chemical agents should be sprayed. Imidacloprid, methidathion and omethoate can be selected and diluted according to the instructions. When spraying, the leaves should be sprayed on both sides, and the effect is fast and good.

Infected with powdery mildew: If flowers are infected with powdery mildew, the plants should be isolated as soon as possible to avoid further infection. An environment with good ventilation and suitable temperature and humidity should also be provided. Clean and burn all infected leaves, and spray carbendazim disinfectant for disinfection. The specific spraying frequency depends on the condition.
