“…According to ISO 22866:2005, spray drift is ‘the quantity of PPP that is carried out of the sprayed (treated) area by the action of air currents during the application process’ . Among the pollutants from PPP use, agrochemical spray drift continues to be a major challenge because pesticides can be deposited in undesirable areas and pose risks to both the environment and bystanders . Spray drift is a more constant threat in bush/tree crops than in arable field crops.…”

BACKGROUND: Drift is one of the most important issues to consider for realising sustainable pesticide sprays. This study proposes an alternative indirect methodology for comparative measurements of drift reduction potential (DRP) generated by airblast sprayers, aimed at overcoming the practical inconveniences and drawbacks of standardized ISO 22866:2005. A test bench in the absence of target crop and wind was employed to measure drift potential values (DPVs). A variation to the proposed method that introduced a crop between sprayer and test bench device was considered to study the canopy effect (absence/presence) and to validate the method. In parallel, direct spray drift measurements (ISO 22866) were performed to obtain the drift value (DV). A representative vineyard airblast sprayer was evaluated in four configurations (a combination of two fan airflow rates and two nozzle types). The configurations tested under the three methods (direct and indirects) were classified according to achieved drift reduction percentages (ISO 22369-1:2013) and compared. RESULTS: Indirect methods discriminated DPVs from different nozzles (conventional, air induction) and fan airflow rate (high, low) combinations.Indirect methods also showed that despite crop influence on drift amount, target absence has a negligible effect when used specifically for DRP determination/classification. In fact, identical DRP final classifications were achieved for the two methodologies tested. Alternatively, all tested configurations resulted in lower DR values following the ISO 22866 field method, which caused different final classifications due to the high dependence of results on external factors. CONCLUSIONS:The alternative test bench methodology, characterized by the absence of target crop and calm of wind, was considered feasible for comparative measurements of airblast sprayer DRP.

“…Exposure via pesticide drift can have a risk impact on local residents, bystanders, livestock, and terrestrial and aquatic ecosystems. There are several potential routes of pesticide exposure for humans associated with spray applications in the field (Butler Ellis et al 2010). These include direct exposure to spray drift at the time of application, both dermal and inhaled; indirect exposure for a period of time following the application through contact with contaminated surfaces and inhalation of volatilised active ingredient.…”

Pesticide Drift: Seeking Reliable Environmental Indicators of Exposure Assessment

Pesticide drift, the physical movement of the pesticide droplets or particles through the air at the time of pesticide application or soon thereafter from the target site to any non-target site, is a constant concern in pesticide use because it inevitably occurs even in the most careful applications, and thus, can increase the possibility of detrimental effects of pesticide use on the environment. Numerous factors can affect the occurrence and the extent of pesticide drift, but the main ones are the application method and the spraying equipment used, the canopy type and height, the weather conditions, the physicochemical properties of the spray liquid, and the decisions made by the applicator. Several pesticide risk indicators have been developed so far to predict the potential environmental impact of agrochemicals (including pesticide drift), many of which have the advantage of requiring a small amount of inputs, being rather fast to calculate and easy to interpret, allowing comparisons both in space and time, and representing an integration of different processes in rather complex systems. However, the information to be included in such indicators varies widely among the different indicators utilized, with the selection process often reflecting to a great extent the specific background of the developers. Thus, different indicators may provide different results, depending on the compartments and effects taken into account, often resulting in difficult judgements about which results are most accurate. Assessing the contribution of each single pesticide to potential environmental problems, in addition to eco-toxicological aspects of the products, requires consideration of the method and the timing of application, without ignoring other aspects of pesticide use. Yet, a major problem in such assessments is the lack of reliable quantitative exposure information, a fact which is also related to the paucity of appropriate pesticide usage data, including the behavioural variable of the pesticide applicator. Nevertheless, it appears that indicators for assessing pesticide impact on the environment will presumably proliferate as long as more complete datasets and indicator prototypes are produced and as long as the pioneering efforts are continuously criticized and improved.
