The Effectiveness of Low Volume Applications of High Concentration Oxine-Copper WP for the Control of Typhula Snow Blight on Turf Grass

Abstract

Experiments were conducted to test the effectiveness of low volume applications of hightly concentrated oxine-copper WP in the control of Typhula snow blight on turf grass at golf courses in Nagano Prefecture. An application of 0.1ml m^-2 of the fungicide diluted 40× was more effective in the control of this disease than that of the commonly used volume and concentration of 0.5ml m^-2 and diluted 200×.
