Symptoms: the disease resistance of R. repens is very strong, and it seldom infects diseases. However, there is a lot of precipitation in summer, which may lead to waterlogging. Soaking in water for a long time may lead to root rot. After the outbreak of the disease, the root will lead to decay, the function of absorbing water and nutrients will gradually weaken, the whole plant leaves will also be yellow and withered, and eventually the whole plant will die.
Prevention and control: pay attention to drainage in summer, and do not allow water to accumulate in flowerpots. When the disease needs to be treated in time, the blackened part should be removed, and then coated with bactericide, which can play a role in inhibiting the growth of bacteria. It is also necessary to disinfect the soil and thoroughly remove the bacteria.
1. Whitefly: if the water in the basin soil is serious, it will cause whitefly to gather together to suck juice, resulting in water shortage and dry up. There is no need to worry about this pest. It can be eliminated with low toxic insecticides.
2. Snail: the rain orchid will grow close to the ground. It may infect the snail after the rain, causing the leaves to be torn. If found, special attention should be paid to remove the harmful leaves in time, and then use the special tetraacetaldehyde.
