Recently, the “Application of Polyhexamethylene Hydrochloride Hydrochloride in Controlling Citrus Acid Rot and Its Preservativeâ€, completed by researchers from the South China Botanical Garden of the Chinese Academy of Sciences, was granted a national invention patent.

Citrus is the world's largest fruit, a non-breathing-type fruit, but the post-harvest breathing metabolism is strong, leading to a rapid decline in its nutritional and flavor quality. For example, the sugar orange peel is thin and juicy, and the post-harvest disease is serious and less resistant to storage. The main diseases are acid rot, green mold, black rot and rot. At present, the most effective way to control the disease of sugar orange fruit is to treat it with low temperature storage combined with chemical fungicide . The fungicides used are carbendazim, methyl thiophanate, imazalil, bismuth salt (Baccarat), etc. The control of decay, especially acid rot, is still not ideal.
Polyhexamethylene hydrazine hydrochloride (PHMG) is a new environmentally-friendly broad-spectrum antibacterial agent newly synthesized internationally. It acts on the cell wall of the pathogen and the membrane system of the cytoplasm to bind to the fatty acids in the cell membrane phospholipids, rapidly breaking through the cytoplasmic membrane of the cytoplasm, breaking the core of the bacterial cells, and allowing the living matter in the pathogen to flow out, thereby achieving the best bactericidal effect. .
According to the China Pesticide Network , the researchers proposed that polyhexamethylene hydrazine hydrochloride can be applied to the prevention and treatment of citrus acid rot, and a new preservative is invented based on this. The preservative can significantly inhibit the rot of citrus fruits such as sugar orange during storage, especially the occurrence of acid rot, and greatly improve the economic value of citrus.
