Requirements for plot trial equipment and how to control

Abstract

Plot trial technology is an important element to guaranty high quality and reproducible trial results – this is relevant for all phases of the development of a Plant Protection Product. Beside proper calibration and homogenous distribution safety aspects play an important role. Calibration and homogenous distributions needs to be controlled before applying each individual trial. In a defined sequence preferable before the season starts these controls should be done and documented by an authorized quality assurance system. Quality parameter should be:
- Distribution pattern controlled via patternator or alternatively individual nozzle flow rate
- Control of pressure gauges
- Control of leakage
Bayer is using the Herbst Sprayer test 1000.
