4.2.4. Foraging activity assessment

1) Foraging activity is observed on all the crop plots during the trial. It is possible to adapt the time of counting to the environment of the trial and to active foraging periods. All the bees present on the crop plots are considered as forager bees. They are all counted one after the other. Counts can be shifted if activity is not considered satisfying (late activity due to morning mist or disturbed by rainfall, etc.).

2) Assessments are managed at least once a day, except on the day of application where assessments are recorded twice before application with one count just before, and three times after with one count 35 min after application.
