Figure 1 (Wind Speed): This figure shows a
series of water-sensitive papers set up at 1.5 metre intervals from 1.5 metres
downwind from the point of spray release to 7.5 m, inclusive. The papers demonstrate
differences in spray coverage comparing a 10 kph wind to a 15 kph wind. The resultant
coverage is graphed to show spray drifts further when wind speed is higher.
