Chitooligosaccharides (COS) are low-molecular-weight oligosaccharides derived from the degradation of chitosan, and they are the only amino oligosaccharides found in nature. With dual carbon-nitrogen nutritional properties, COS can alter soil microbial communities, inhibit plant pathogens, promote the growth of beneficial microorganisms, and enhance plant disease resistance and yield. These characteristics make COS highly valuable in …

Prohydrojasmon (PDJ) is a highly bioactive derivative of jasmonic acid, an endogenous plant growth regulator. It induces the orderly synthesis of ethylene, promoting anthocyanin production and accelerating fruit coloration. Once absorbed by the plant, it metabolizes into jasmonic acid, aiding in growth promotion, stress resistance, and ripening. Physical and Chemical Properties Appearance: Colorless to pale yellow …
