What diseases and pests does Torch Flower have and how to prevent and control them

1. Diseases

Symptoms: The main disease of torch flower is rust, which is mainly caused by the parasitic fungus rust. It harms the leaves and flower stems, causing small blisters to appear on the affected parts. Some of them may also cause tumors, bent branches, and bushy branches on the branches, and even cause leaf fall and poor growth. If it is serious, it will cause a large amount of water in the plant to evaporate, causing the plant to die quickly.

Prevention and control: Take preventive measures on a daily basis, strengthen ventilation, and promote contact with fresh air to reduce the occurrence of diseases. In the early stage of the disease, you can spray with 400 times diluted 25% carboxin emulsifiable concentrate or lime-sulfur mixture.

2. Pests

Symptoms: It is also very easy to be infected by pests, mainly beetles, which are prone to bite the flowers during the flowering period, causing problems in the growth of the entire plant and seriously affecting its appearance.

Prevention and control: In daily maintenance and management, prevention is necessary. In winter, pay attention to pruning and cut off branches infested with insects. It is also necessary to remove the weeds piled around to reduce the source of disease. If the situation is serious, you can use omethoate.
