The Bayer Pollen Beetle Predictor forecasts the start, peaks and progress of pollen beetle migration into winter OSR crops giving you the information needed to tell when it’s time to get out to the field – or not – and see what’s happening in crops.

Compared with previous advice – to monitor from green to yellow bud whenever temperature is 150C or higher – using Bayer Pollen Beetle Predictor can help reduce monitoring time. It also focuses monitoring effort to when it’s most needed, helps avoid unnecessary spraying and improve treatment timing accuracy.
