Objectives and competences
Students explore, analyse and understand:
-methods and procedures of PPP application,
-devices (equipment) for pesticide (PPP) application,
-methods of device calibration for application of PPP-s,
-methods of determination of pesticide dose per unit of target area (TRV, LEARP, etc.),
-relationships between pesticide application methods and biological performance (achieved efficacy) of PPP,
- and research methods used in studies of equipment for PPP application and studies of relationships between application methods and biological performance (achieved efficacy) of PPP.
Content (Syllabus outline)
PPP = plant protection product
-survey of pesticide application methods and pesticide (PPP) formulations
-types of devices for application of PPP-s and types of application procedures (spraying, dusting, weeping, etc.)
-physical and chemical phenomena involved in partial steps of PPP application (droplet production, droplet travelling, droplet collision with target surface, droplet deposition and retention, droplet dripping, pesticide deposit degradation etc.)
-methods of determination of pesticide dose per unit of target area (TRV, LEARP, etc.)
-mechanisms of simultaneous regulation of spray output during the driving
-methods of calibration of devices for application of PPP-s
-nozzle types for field boom sprayers
-nozzle types for air-assisted sprayers
-influence of sprayer operating parameters (driving speed, spray volume, pressure, fan air flow rate …) on biological performance of applied PPP-s
-mechanisms and procedures for pesticide drift regulation and prevention
-research methods in pesticide application and studies of relationships between application methods and pesticide biotical performance
Learning and teaching methods
• classroom lectures, seminars
• review of different types of documents (standards, etc.)
• practical exercises in measurements of equipment deposition characteristics (coverage analysis by use of WSP collectors – work with image analyses devices, deposit analysis by use of different tracer techniques, etc.)
Intended learning outcomes - knowledge and understanding
Students are able to:
• calibrate equipment for application of PPP,
• determine PPP dose per unit of target area by different methods,
• practically use common equipment for application of PPP-s,
• contribute to work in development and construction of new equipment and devices for application of PPP-s,
• perform sophisticated trials with equipment and devices for application of PPP-s,
• contribute to the application equipment inspection procedures,
• and carry out research tasks in PPP application methods and evaluation of impact of application methods on biological performance of PPP-s.
Intended learning outcomes - transferable/key skills and other attributes
