Abstract
By using a small-sized power sprayer (power spray:ARIMITU CS-10K) and a power sprayer drivel battery (battery sprayer:TOSHIBA GARDEN SPRAYER EH-15), the eftect of spray pressure on the contral of Gray blight was studied.Two fungicides, chlorothalonil (75% WP, dilu-tion:1/600) and captafol (80% WP, 1/2000) were sprayed 200 litres per 10 a. to tea bushes within a few hour after the artficially inoculation of Pestalotia longiseta SPEGAZZINI. The discharge rates of the power sprayer and the battery sprayer were 4.76l/min and 0.29 1/min, respectively.The spray pressures on an area of 5×5 cm at a distance of 30 cm from nozzle of a sprayer were 159g in the power sprayer and 2g in the battery sprayer.In the application of chlorothalonil, the number of diseased leaves was significantly fewer in the power sprayer than in the battery sprayer. On the case of captafol, the power sprayer also showed the effective control on Gray blight.
