White silk disease

White silk disease often occurs in the plum rain season. At the beginning of the disease, the leaf base of yellow cicada orchid was covered with white silk, which eventually led to rotting of the rhizome.

The control method is to remove the bacteria-carrying basin soil and sprinkle it with pentachloronitrobenzene powder or lime. If you want to get a radical cure, you need to pay attention to ventilation and light, and the basin soil is well drained.

Anthrax

Anthrax occurs all the year round, especially in the high temperature and rainy season. The disease spot will gradually extend from the leaf tip to the rhizome. At first, the disease spot is brown, and as the disease spot expands, it will gradually turn black, and in severe cases, the whole plant will die.

The method of prevention and control is to actively change the environmental conditions of Bodhisattva. It can also be sprayed with 1500-fold solution of 50% methyl topiramate wettable powder once a week, supplemented with 1% equivalent Bordeaux solution, once a semimonthly, 3-5 times continuously.

Scale insect

Scale insects are commonly known as "blue lice". They often multiply rapidly in an environment of high temperature, humidity and poor air circulation.

The control method is to spray 1% omethoate or 1500 times 50% Mala sulfur during the incubation period of scale insects. If the number of pots is small, you can also brush off the eggs by yourself.
