The main objective of this work was to compare two methods to estimate the deposition of pesticide applied by aerial spraying. Hundred and fifty pieces of water sensitive paper were distributed over an area of 50?m length by 75?m width for sampling droplets sprayed by an aircraft calibrated to apply a spray volume of 32?L/ha. The samples were analysed by visual microscopic method using NG?2 Porton graticule and by an image analyser computer program. The results reached by visual microscopic method were the following: volume median diameter, 398±62 ? m; number median diam- eter, 159±22? ? m; droplet density, 22.5±7.0?droplets/cm 2 and estimated deposited volume, 22.2±9.4?L/ha. The respective ones reached with the computer program were: 402±58? ? m, 161±32? ? m, 21.9±7.5?drop- lets/cm 2 and 21.9±9.2?L/ha. Graphs of the spatial distribution of droplet density and deposited spray volume on the area were produced by the computer program. |
