Proper pollination is essential for optimal fruit set and production. In the past, growers relied on honeybees, manual pollination or plantgrowth regulators, depending on the crop being grown.

•  In general, honeybees don't work well in greenhouses or tunnels. They are generally less effective or inadequate during periods of low temperatures (under 15°C/59°F) and cloudy weather. 
•  Manual pollination is time consuming and difficult to manage. 
•  Hormones often result in low quality fruits, which are not saleable (soft, malformed and seedless fruit).
