Disease and insect pest control of cymbidium

Sclerotium rolfsii

There are two most likely diseases for this flower. The first one occurs mostly in seasons with heavy rainfall, and white filamentous substances will appear on the plant. This may be white rot, which can cause root rot. If it is serious, the entire plant will not survive, so it must be dealt with in a timely manner.

First, scrape off the part of the soil where bacteria have appeared, and then spread an appropriate amount of lime or other bactericidal substances on the soil. If you want to cure it completely, you need to move the flower pot to a place with better ventilation and light, and ensure drainage. If the plant is seriously infected, you can simply pull it out and burn it so it does not infect other plants.

anthrax

This is the second disease that it will develop. The symptoms start to spread from the tip of the leaves, so it is not easy to be discovered at first, so friends need to observe diligently. Especially when the temperature rises and the amount of water increases, the symptoms will become more obvious.

Once brown spots are found, timely prevention and treatment are necessary, otherwise it may lead to the death of the entire plant. In addition to improving the external environment, it is also necessary to spray pesticides in a timely manner. If you do it once a week, 3-5 times will be enough.

Scale insects

They also like to appear when the temperature rises, and they reproduce faster in such an environment, especially when the air circulation is poor, the situation will be even more serious. Therefore, after the insects appear, in addition to removing the insects manually, the plants should be placed in a ventilated place, and then sprayed with pesticides such as malathion regularly, but the dosage and frequency should be determined according to your own situation.
