Abstract
Effect of potassium phosphonate on control of potato late blight was evaluated at two fields in Jeju island. The chemical showed 82.5% control value in field located at low seacoast with 100 m elevation, while dimethomorph copper oxychloride showed 75.9 % control value. However, its control value was only 40% in another field located at mid-hilly area with 300 m elevation, in which environmental conditions of high hummudity and often rainfall were favorable to the disease development. Application intervals of the phosphonate from 7 to 15 effectively suppressed the disease and did not show statistically different control values among the spraying intervals. Results indicated that phosphonate similarly or more effectively controls potato late blight than fungicide, however, its control value could be vared according to enviromental conditions for the disease development and 15-d spraying intervals ware sufficient to suppress ther disease.
