Figure 3

Box plots of the deposited dye, visually assessed into 10% bins, found on upper (adaxial) and lower (abaxial) leaf surfaces demonstrate that the spot-gun application (top) provided similar coverage on both leaf surfaces whereas the broadcast application (bottom) did not. Each treatment had different application rates, therefore a one-to-one comparison across treatments cannot be made. The line in the centre of the boxes shows the median value, while the first and third quartiles are the bottom and top boundaries of the box. The whiskers extend to the minimum and maximum values. The data were bound by the upper limit of the 91-100% bin and the lower limit of the 1-10% bin.
