The values outside and inside of parentheses are the total and daily mean of observed data, respectively. a) Measured values taken from the conventional plots (labeled as LA/LV-S1,S2, LA/LV-S). b) Measured values taken from the bare plots (labeled as LA/LV-B). c) Measured values taken from the zero-percolation plots (labeled as LA/LV-Z). d) Measured values taken from the foliage application plots (labeled as LA/LV-F).
