  1. TOPPS-PROWADIS Stakeholder Workshop – Brussels, 26 April 2012 DIAGNOSIS &DECISION TOOL DRIFT Greg DORUCHOWSKI ResearchInstitute of Horticulture Skierniewice, POLAND

  2. Keyquestions for betterdecisions Whatis the risk of drift in the S P E C I F I Cweather and field situation ? Whatfactorsneed to be considered to assess the risk? Whatmeasurescan be used to mitigate the risk ? How efficientare the measures ? DIAGNOSIS & MEASURES

  3. Objectives • Development ofa practical tool to: • diagnose the drift risk • propose riskmitigationmeasures • help the operator makebetter decisions • reduce contamination of water and othersensitiveareasdue to spray drift

  4. Assumptions Drift Risk Diagnosis - Advice & awarenessraisingtool • visualevaluation of driftrisk • performed by farmer/advisorhimself • for specific/currentconditions • by simple choice of options • highlightingkeyriskfactors to createawareness and understanding of the problem • givingadvice on driftmitigationmeasures and instant indication of theireffectiveness

  5. Diagnosis • identificationof the nature and cause of PROBLEM > DRIFT • logics • analytics • experience • determination of CAUSE & EFFECT relationship • mitigations for problems • solutions to issues

  6. Diagnosis CAUSE & EFFECT (Ishikawa, K., 1968) Meteo & Field Conditions SITUATION Effect Cause Equipment Process People PROBLEM Secondary cause Primary cause Environment Management Materials SprayingAdjustment Equipment of Sprayer MITIGATION

  7. Precondition Standard situation: Wind 3-4 m/s Temperature 15-25 °C Humidity 40-60% Nozzles ISO-03 Pressure 3 bar Boom height 50 cm Drivingvelocity 6-8 km/h Where the risk of contaminationexist ? ACCEPTABLE RISK – sprayingwithin the zone of awareness Buffer zone Buffer zone Boom width Boom width Zone of awareness Zone of awareness NEGLIGIBLE RISK – sprayingbeyond the zone of awareness

  8. Precondition Is spray applied in the „zone of awareness” ?

  9. SITUATION Meteorologicalconditions • AIR • temperature • relativehumidity • WIND • direction • velocity T°C V m/s RH%

  10. SITUATION Field conditions • crop • adjacent vegetation TREES SHRUBS MEADOW CROP HEIGHT WATER COURSE
