Bumblebees contribute to high-quality blackberries

Why use bumblebees in blackberry cultivation? Particularly in humid conditions, these diligent pollinators are very welcome. The reason being that excess pollen can be a breeding place for fungi in wet periods. By collecting all the pollen from the blackberry blossoms, bumblebees can play a key role in producing high-quality fruit.

Biobest advisor Jurgen Bouveroux, who speccializes in crop pollination, advises many soft fruit growers, producing strawberries, raspberries and blackberries from early spring through to late autumn – often in tunnels.

“Blackberries distinguish themselves from other berries by the copious amounts of pollen the flowers produce,” he said in a news release. “In wet periods, I recommend deploying bumblebees. Highly effective pollinators, they collect all the pollen so that nothing is left behind.”

Finding the right balance

In wet conditions Jurgen advises growers to install one Standard Hive per 500 m2. “In drier periods less bumblebees are needed as over-pollination is also undesirable,” he explains. “It is all about finding the right balance. At Biobest we provide tailor-made advice to ensure growers deliver higher volumes of larger, high quality fruit throughout the season.”
