It spreads throughout the bell, and sometimes spreads onto the cotton fibers to produce a uniform layer of pink or light red mildew. After the rain, it easily sticks together. It becomes a pink block, which causes the disease bell to fail to crack, and the cotton fiber decays into a dead-petal shape. After the seeds become infected, the germination rate drops.
