USE OF POLYHEXAMETHYLENE GUANIDINE HYDROCHLORIDE AS PRESERVATIVE FOR PREVENTING AND CONTROLLING CITRUS SOUR ROT AND ITS APPLICATION

摘要

The use of polyhexamethylene guanidine hydrochloride as preservative for preventing and controlling citrus sour rot and its application are disclosed by the present invention. The citrus preservative calculated by 100% total mass fraction comprises 0.05%-0.5% polyhexamethylene guanidine hydrochloride, one or a mixture of several of the following: 0.05%-0.2% imidazole bactericide, benzimidazole bactericide, pyrimethanil, fludioxonil or azoxystrobin, and 0.02%-0.15% polyethenoxy ether emulsion or quaternary ammonium salt emulsion, and the rest is water. The citrus preservative can significantly inhibit the decay of citrus fruit such as Citrus microcarpa during storage, especially the incidence of sour rot. So the commercial value of citrus is obviously increased.
