Polyfly hoverflies are already pollinating onion and carrot in South Africa
Spring is advancing in the Southern Hemisphere, bringing with it a key moment for agriculture: the flowering season in South Africa. Our hoverflies are already at work in the field to achieve maximum pollination efficiency in essential crops such as onion and carrot.
High-quality seed production leaves no room for improvisation. Whether in open fields or in isolation cages, effective pollen transfer is decisive throughout the seed multiplication process. This is where our natural pollinators stand out from traditional pollinators:
Onion (Amaryllidaceae)
In onion seed production, pollen transfer between florets within the same umbel and between different umbels — and, in hybrid production, from the pollinator line to the male-sterile line — is the key factor behind a successful, abundant harvest. QUEENFLY® and GOLDFLY® have proven their effectiveness on these floral structures, offering full flexibility to work on their own or in combination with other pollinators. The result? A higher yield per hectare, delivering valuable F1 hybrid seed and heavier seed with optimal germination capacity.
Carrot (Apiaceae)
In hybrid carrot seed production, cross-pollination is essential: pollen must travel from the pollinator line to the male-sterile line. Its intense, long-lasting bloom, made up of dozens of umbels and thousands of tiny flowers, calls for pollinators that are morphologically adapted to carry pollen to even the smallest stigmas. Our hoverflies move nimbly across these small flowers, producing carrot seed of exceptional vigour and high reliability in hybrid seed production.
Present in South Africa from the first blooms, thanks to our international logistics
The start of the flowering season in South Africa reaffirms Polyfly’s global commitment. We don’t see pollination as a cost, but as the cornerstone of the seed producer’s business. Thanks to our international logistics, our hoverflies are in the country from the moment flowering begins, helping growers achieve higher yields and more vigorous crops.
