DCCA is a highly effective, broad-spectrum and new systemic fungicide with strong disinfection performance. It can kill all kinds of bacteria, algae, fungus and germs (bactericidal rate can reach99% at a concentration of 20ppm). If stored under drying conditions, no more than 1% effective chlorine of DCCA would decrease due to its stable chemical property, as well as other advantages such as convenience in storage and transportation, safety in use, less consumption and long duration of drug effect. The bactericidal effect of DCCA is carried out through releasing hypochloric acid slowly on the surface of crops, changing the membrane permeability, interfering with physiology of enzyme system and affecting DNA synthesis through denaturing mycoprotein, all of which result in the quick death of pathogenic bacteria.

DCCA is widely used as biocide in circulating cool water system and swimming pool. When used in circulating cool water system, the dosage of 50-80ppm every 2-3 days in summeris preferred, in spring and autumn, every 3-5 days and in winter every 5-7 days. For insurance of effects, nonoxidative disinfector may be also added into this product.
