As a synthetic functional analog of salicylic acid, 2,6-dichloroisonicotinic acid(ina) is effective in inducing the host disease resistance of a plant against a pathogen. The effects of ina on controlling postharvest blue and green molds and anthracnose decay and defense-related enzymes on citrus fruits were investigated, and the ascorbic acid of naturally infected citrus flavedo was also measured. Results showed that 1.0 mmol L^(–1) ina treatments significantly reduced blue and green molds and anthracnose decay development on both wound-inoculated fruit and naturally-infected fruit compared with the control fruit. The treatment effectively enhanced the β-1,3-glucanase(GLU), chitinase(CHI), phenylalanine ammonia-lyase(PAL) and peroxidase(POD) activities and the polyphenol oxidase(PPO) in flavedo. The results presented here suggest that ina might be used as a chemical fungicide substitution to control postharvest diseases in citrus fruits.

The control and prevention of a growing number of diseases will only be effective if local and national public health policies adopt a global *** role of mass transportation,immigration,tourism, demographic growth,tourism and bioterrorism are but some of the engines behind disease dynamics and disease *** using recent epidemic outbreaks will be used to highlight not only the importance of these epidemic drivers but also to advance the importance of health policy perspectives without borders.
