Symptoms: leaf blight, putrefaction and anthrax are common diseases. The parts of the disease are first concentrated on the leaves, which is difficult to distinguish at the beginning. First, the leaves appear spots, leading to yellow leaves, and finally the whole plant rots due to serious disease.
Prevention and control: pay attention to prevention during daily maintenance and planting, strengthen ventilation, and do not make the plant in a sultry environment. If it is found that the infected leaves need to be removed in time to prevent infection to other healthy parts. It is also necessary to spray carbendazim solution for disinfection once a week for about three times.
Symptoms: the most likely insect pest to be infected is Starscream, which is easy to breed in the dry and hot environment. If the surrounding environment is poorly ventilated, it will be easier to breed. These pests will gather together to suck the sap of the plant, causing its stems to turn yellow and wither, and even cause death if it is serious.
Prevention and control: usually, windows need to be opened for ventilation, and a certain humidity needs to be increased by spraying water, so as to prevent its occurrence. It is also necessary to spray Omethoate solution regularly for sterilization, about once every 15 days. If it is first artificially scraped or removed directly, it will be used to kill with serious pesticide.
