When cutting leaves with a single ring, the upper part of the disease spot is easy to die. In the later stage, the lesion often falls off into a perforation. The disease of leaves near the ground often causes local rot, and in serious cases, it causes stem base rot or whole plant inversion. It is easy to get sick in high temperature and rainy season.

Prevention and control methods: reduce soil moisture. At the initial stage of the disease, Bordeaux solution, 53.8% can kill 2000 dry suspension 1000 times or 47% Garinon wettable powder 700x solution, spray 2-3 times in a row, once every 5-7 days.

Tiger skin orchid rot

Harmful symptoms: occur on the leaves. The disease spot is water-stained spot in the initial stage; after expansion, the disease spot is from round to irregular, dark gray, soft rot, slightly sunken; in the later stage, the disease spot is dry and sunken, grayish brown, the edge is reddish brown, and black mildew spots appear under wet conditions.

Bacterial soft rot of tiger skin orchid

Harmful symptoms: after infection, the leaves changed from green to light yellow to grayish yellow, water-immersed soft rot appeared at the base of the stem near the ground, and the injured leaves were easy to fold in the later stage.
