Abstract: The field trial of Oligogalacturonides controlling apple mosaic was done ,the results indicated that the controlling efficacy of Oligogalacturonides diluted 300-500 times by water was 87.81%~92.08% which was higher than that 81.11% of contrast pesticide-Dukexing.The range of increased yield of the tree sprayed oligochitosan was 20%~23%. Oligogalacturonides is a good biocide to controlling Apple mosaic.
