Control of silver-leaf disease on apple trees


, : Control of silver-leaf disease on apple trees. Fruit Trees (4): 48-49

Silver leaf (Chondrostereum purpureum), a serious disease of orchards in the Changjiang river valley and along the Yellow River, can be controlled to some extent by the following measures: (1) exposing the thick roots during the growing season within a circle of 1.5 m diameter from the trunk, spraying once with a dilute fungicide, dressing monthly with dilute fermented night soil, and earthing-up after leaf fall; (2) pruning away diseased branches and disinfecting the wounds; (3) peeling the trunk bark thoroughly while avoiding injury to the cambium during fine weather in May; (4) applying fertilizers in split doses in an N:P2O5:K2O ratio of 1-1.3:1:1-1.3 jin per 100 jin fruit, and regulating the yield at 1500 kg/mu in order to maintain tree vigour; and (6) injecting kasugamycin into the bark through three 10-cm-deep holes made with a hand drill. (1 jin = 0.5 kg, 1 mu = 0.067 ha.).
