L'eau de ruissellement d'un mince manteau de neige peut être chargée de poussière de sol et elle en aura accumulé davantage au moment d'atteindre la fosse. Par ailleurs, l'herbe touchée par la sécheresse dans les zones tampons peut être parsemée et moins efficace pour filtrer les particules.

There are other issues to keep in mind when dugout water levels are low. During a drought, there is less runoff to dilute accumulated nutrients and the runoff usually carries more nutrient-laden particles. Runoff water from a small snowpack may be laden with drift soil and will pick up more soil as it flows into the dugout. Compounding matters, drought-stressed grass in the buffer strip may be thin and less effective at filtering out particles. Nutrients can also be added by blowing soil. These nutrients may then, in turn, become more concentrated by evaporation during hot summer weather.

Les essais ont permis de confirmer que le nouveau modèle du PRD obtenait un équilibre satisfaisant entre une bonne atteinte de la culture et couverture du feuillage ainsi qu'une bonne efficacité (de 15 à 20%) de récupération du pesticide. Il a été démontré que la technologie du PRD réduisait la dérive de 90% et qu'elle pourrait servir à réduire les zones tampons jusqu'à 20 m sans conséquence pour l'environnement.

The tests confirmed that the new design achieved a satisfactory balance between a good canopy penetration and leaf coverage, and good efficacy (15-20%) in pesticide recovery. It was demonstrated that the DRS technology reduced drift (ground deposition) by 90% and that it could be used to reduce buffer zones by up to 20 m without impacting the environment. Field trials showed that late in the season, when vine canopy reaches its full size and density, 10% of the applied spray can be recovered and recycled. An economic analysis based on drift reduction and pesticide savings indicated that the DRS sprayer pays for itself in 15 years under current regulations. The technology is more economically viable if recognized as a drift reduction method for buffer zone management, in which case, the payback period can be as short as 2½ years.

Les pratiques qui ralentissent l'écoulement de surface, comme l'aménagement de zones tampons riveraines, les cultures couvre-sol d'hiver et le maintien des résidus de surface, aideront aussi à réduire le risque de contamination de l'eau.

Increased efforts are required throughout Canada to minimize the risk of nutrient, pesticide and coliform movement to surface water bodies and leaching beyond the rooting depth of vegetation. This is particularly so in higher rainfall areas of the country. This risk can be further reduced through practices such as regular soil testing and adoption of precision agriculture (better matching agricultural inputs application to localized field conditions), that increase the efficiency of nutrient use. Practices that mitigate surface runoff, such as establishing riparian buffer strips, winter cover crops, maintenance of surface residue, etc. will also contribute to reduced risk to water quality.

Une solution de pulvérisation de rechange était nécessaire pour éviter la perte de pesticide hors-trajectoire, en particulier en matière d'application des paramètres des zones tampons prévus par la loi près des endroits vulnérables (de 20 à 30 m au Québec).

With conventional airblast radial sprayers only 55% of the treatment solution is deposited on the foliage, 25% ends up on the soil and 20% goes away as airborne drift. Reducing off-target loss of spray solutions can lead to reduction in risk from pesticide contamination and better efficacy of pesticide applications. An alternative spray method was needed to avoid the off-target pesticide loss, especially in the context of enforcing legal buffer zone parameters close to sensitive areas (20-30 m in Québec). Agriculture and Agri-Food Canada researchers had developed a new drift recovery sprayer (DRS) technology designed for use in apple orchards which combined the advantages and configurations of both tower and tunnel sprayers. A prototype of DRS was later adapted for use in vineyards and other crops with similar canopy geometry (e.g. raspberries). This study evaluated the potential of the vineyard DRS prototype to reduce ground contamination and airborne drift in vineyards.
