Imidazolinone-tolerant black oil hybrids for simplified weed management
Black oil sunflower (Helianthus annuus L.) is one of the highest-value oilseed crops available to commercial growers. Its seeds contain 40 to 50 percent oil by dry weight — substantially more than confectionery sunflower varieties — making it the preferred choice for edible oil, biodiesel, and high-energy livestock feeds. Yet black oil sunflower is also […]

Planting date is not a calendar decision. It is an agronomic one. The difference between a productive sunflower crop and a mediocre stand often traces back to a sowing window of just ten to fifteen days. For professional growers, timing sunflower planting means reconciling soil temperature, varietal cycle length, downstream market requirements and regional climate […]

Choosing where to buy sunflower seeds for planting is not a simple sourcing question.It is an agronomic decision that conditions crop performance, market access, and production regularity over the season. Sunflower is grown across multiple filières: oilseed crushing, grain markets, animal feed, bird feed, forage, and occasionally as a cover crop.Each outlet imposes different varietal expectations, tolerance […]
Read moreBlack oil IMI sunflower seeds are hybrids combining a black-husk oilseed format with genetic tolerance to imidazolinone herbicides. This IMI trait allows growers to apply specific ALS-inhibiting herbicides while maintaining crop safety and achieving efficient weed control.
Our varieties are bred to ensure stable IMI expression and consistent performance across a range of environments.
Our varieties integrate robust IMI tolerance, competitive yield potential and a black oilseed format adapted to crushing. Developed through advanced varietal creation, our hybrid sunflower seeds deliver uniform plant architecture and reliable behaviour under field constraints.
Through our agronomic solutions, growers receive guidance to optimise weed-control programs and protect trait performance.
Black oil IMI hybrids differ from conventional non-tolerant hybrids by enabling the safe use of imidazolinone herbicides. Their black-husk format remains ideal for oilseed processing, while IMI tolerance provides additional weed-control capacity.
By simplifying weed control, IMI hybrids help growers secure yield in regions with challenging weed spectra. The black oilseed format aligns with conventional oilseed supply chains, ensuring compatibility with established processors.
Successful cultivation requires attention to weed-management timing, crop nutrition and correct placement. Our hybrid sunflower seeds express IMI tolerance reliably when grown under adequate stewardship.
Harvest at correct moisture to preserve seed quality and protect oil characteristics. Dry, ventilated storage prevents degradation and supports long-term seed stability.
Choosing an IMI hybrid depends on weed pressure, maturity requirements, climate and oil-market targets. Our ranges offer multiple options adapted to varied production conditions.
Our agronomic solutions provide growers with guidance on herbicide timing, sowing density, nutrition management and stewardship practices, enabling our hybrid sunflower seeds to deliver full performance.
They are sunflower hybrids combining black oilseed format with tolerance to imidazolinone herbicides.
The trait allows safe use of ALS-inhibiting herbicides, enabling targeted weed control without damaging the crop.
Our varieties provide stable IMI expression, strong yields and compatibility with oilseed processing.
Only approved imidazolinone herbicides should be used following recommended timing and stewardship guidelines.
Growers must rotate herbicide modes of action, control volunteers and avoid repeated IMI-only programs.
IMI hybrids offer improved weed control flexibility while maintaining similar oilseed processing characteristics.
Volunteers must be controlled using alternate herbicide modes of action in following crops.
IMI programs target specific broadleaf and grass weeds problematic in many rotations.
Consider weed spectrum, maturity class, expected yield and local performance data.
No, the IMI trait does not alter the oil profile or processing characteristics of the seeds.
To situate this IMI profile within the sunflower segment, growers often compare it with its parent category Black Sunflower Seeds and the broader Hybrid Sunflower Seeds, while also reviewing nearby options such as Black Sulfo Sunflower Seeds and Striped IMI Sunflower Seeds, which share similar agronomic behaviour and tolerance profiles.
