The blight of impatiens
[symptoms] mainly damage the stem. The first root and stem showed oil-stained dark green strip patches, which became black-brown and irregular after rapid expansion, and in severe cases, the stems and leaves all blackened, and the plant was quickly folded and the root neck sunken, resulting in plant lodging and death. Under the condition of humidity saturation and long duration, the disease developed sparse white mold, that is, the sporangium and sporangium of the pathogen. [morphological characteristics of pathogens] grow fast and produce more spores on CMA, OMA and V4A medium, and grow on PDA medium
