Chronic soft rot prevalent in Taizhou this summer

At the onset of the disease, the old grass first yellowed the central leaf for more than a month, and then the foot of the leaf dried up, and then it was also transferred to another leaf, slowly the whole plant died. This disease is neither like stem rot nor soft rot, the yellowed central leaf is gently pulled out to see a blackened water quality, characterized by slow pathological changes. In the early stage of the disease, water stains are often inappropriate for a moment and do not attract enough attention. When it is found that there is a universal image in the whole basin, it is too late, and it is more harmful to orchids. Taizhou calls it chronic soft rot!

Treatment: the root was irrigated with agricultural streptomycin or Ke, and chloramphenicol eye drops were dropped into the central lobe and phosphorus stem.
