Abstract
The present investigation was to determine the antifungal ativity of different chitosans and chito-oligosaccharides against Alternaria solani. Out of four chitosans tested, chitosan DA10 and 134 was recorded as 53.44 and 51.47% at 1000ppm, respectively where as at 1500 ppm conc, the inhibition percent was 67.54 and 59.01%, respectively. Among the treatments, chitosans exhibited maximum growth inhibition of pathogen at 1500ppmconcentration.Chito-oligosaccharides obtained by enzymatic degradation of the chitosans using promising biocontrol agents have exhibited a positive effect on the growth of the test pathogen showing that they were not effective in reducing the disease.
