Natupol Excel is especially developed for crops with a high amount of flowers per m2 (35-60 flowers) per week, such as cherry or snack tomatoes, (straw)berries and for crops grown under artificial light or in warmer environments.
How does Natupol Excel work?
After their release, worker bumblebees will start pollinating the crop. They are supported by more workers born in the weeks after their introduction.
The Natupol Excel contains a larger volume of sugar water, adjusted to the needs of the crop. This increases the overall pollination potential and gives the bumblebees more energy to control their own microclimate. The hive also houses a larger colony and thus requires more cooling. Therefore the ventilation openings are modified to improve ventilation. Screens in the ventilation openings prevent insects from entering the hive.
The improved visibility of the hives (Beevision) among the crop is based on the way bumblebees see. Bumblebees now easily find the hive, fewer bumblebees get lost in the greenhouse and pollination improves.
