A Chitosan Composite Film Sprayed before Pathogen Infection Effectively Controls Postharvest Soft Rot in Kiwifruit
Soft rot caused by <i>Botryosphaeria</i> <i>dothidea</i> and <i>Phomopsis</i> sp. is a critical disease in kiwifruit. In order to efficiently control soft rot, a 28.6% chitosan composite film (CCF) containing chitosan, dextrin, ferulic acid, calcium, and auxiliari...
