KWS YSTOS CL

Technical Superiority of Clearfield in KWS Justos CL

The winter rapeseed hybrid KWS Justos CL, developed by the German breeding giant KWS, serves as a high-precision tool for farms prioritizing weed management and consistent yield output. The hybrid's architectural foundation is its full genetic compatibility with the Clearfield herbicide technology, ensuring clean fields without compromising the crop's physiological development.

Phytosanitary Defense Against Phoma

A core engineering goal in the development of KWS Justos CL was reinforcing the plant’s innate immunity against fungal threats, particularly Phoma. The pathogen Phoma lingam poses a severe risk to vascular health and stem structural integrity. KWS breeders implemented a multi-faceted resistance strategy, focusing on high tissue lignification at the root neck, which acts as a physical barrier against spore infiltration, effectively reducing the risk of lodging.

Planting Density and Performance Management

The recommended planting density ranges from 400,000 to 500,000 plants per hectare. This flexibility allows agronomists to optimize the crop based on specific soil types and sowing windows. At the 400,000 threshold, the hybrid exhibits excellent branching capacity, maximizing individual plant productivity. Conversely, the 500,000 rate is ideal for regions with shorter autumn seasons, ensuring rapid canopy closure to shade out weeds early on.

• Clearfield Technology: Efficient control of a broad weed spectrum, including hard-to-kill species.
• Biological Resistance: High tolerance to Phoma, reducing the dependency on prophylactic fungicide applications.
• Versatility: Exceptional adaptability across diverse European climatic zones and soil conditions.
