Symptoms and control methods of cotton boll Aspergillus rot
Symptoms It occurs in all cotton regions. It mainly damages cotton bolls. Initially, water-soaked yellowish-brown spots appear at cracks, insect holes, wounds or splits on the cotton boll, followed by yellow-green or yellowish-brown powdery material that fills the boll cracks, causing the cotton boll to fail to open normally. During continuous rainy weather or high humidity, yellowish-brown or yellow-green fuzzy mold grows, namely the pathogen's conidiophores and conidia, and the cotton lint quality is contaminated to varying degrees or becomes dry-rotted and deteriorated. Pathogen Aspergillus flavus Link, called yellow aspergillus, Aspergillu

Control Methods for Bacterial Gill Rot Disease (Flexibacteriosis) in Koi
I. Symptoms: The gills of diseased fish rot and carry some sludge. Sometimes the tissue at the tips of the gills rots, causing the gill edges to become incomplete and ragged; sometimes one or more spots on the gills rot, but not at the edges. The inner membrane skin of the operculum (gill cover) becomes congested, and sometimes breaks down and corrodes into a roughly circular transparent area, commonly known as "open skylight." Because the gill tissue is destroyed, the diseased fish has difficulty breathing and often swims near the water surface in a floating-head manner. In severely affected fish, the floating-head phenomenon persists even after changing to clean water. II. Pathogen: Cytophaga columnaris (columnar flexibacterium), synonym: Myxococcus piscicola.
