Critical issues in the evaluation of spraying quality of canon mist blowers : a methodological case study
2012
Douzals, J.P. | Cotteux, E. | Rombaut, M.
The quantitative evaluation of a boom sprayer is typically achieved upon plants or ground distribution (in a sprayed area) and spray drift (outside sprayed area, downwind) as defined by International Standards. When transposed to mist blowers, protocols & methodologies might appear unadapted or undefined. This paper introduces experimental feed-back in the assessment of mist blower spraying quality used for crop protection (banana crops) or environmental purposes (mosquito control). The definition of an effective sprayed zone according to a spray distribution pattern is discussed through the comparison of two methodologies. The comparison between several types of sprayers might be critical as spraying conditions may vary (e.g. number of spraying sides). The results on drift values of a mist blower used on banana crop will be discussed as an example.
