Your key to successful beet growing

SMART KWS varieties offer an additional option for beet cultivation. In bottleneck situations in spring.

CONVISO® SMART with only two applications can help to free resources and control challenging weeds (e.g. mallow, wireweed).


Only SMART KWS varieties have the specific tolerance to the new herbicide CONVISO® ONE.

The specific tolerance of SMART KWS varieties enables best crop safety during herbicide application – it protects the beet from phytotoxic damage.

Difference with our previous seeds

SMART KWS varieties will eventually be equipped with the same tolerance package as our classic varieties such as Rhizoctona tolerance. Ongoing breeding efforts are aiming to improve yields as well as broaden our product portfolio and deliver the right varieties to growers.

Breeding History

The backbone of the new system is a family of new SMART KWS varieties. Classic breeding techniques were used to identify and to integrate the tolerance to ALS (Acetolactat-Synthase)-inhibitors into KWS breeding programs to make SMART KWS varieties the perfect partner to the herbicide CONVISO® ONE.

The specific ALS-tolerance of the SMART KWS varieties allows us to use the new herbicide CONVISO® ONE, efficient against grass and broad-leaf weeds. This broad-spectrum control was not possible in beet before. As in classic breeding, a new breeding program takes some generations to reach highest performance.

The search for this new specific tolerance to an ALS-inhibiting-herbicide and the development of the first generations of varieties was a dedicated piece of KWS research and development.

It took more than 15 years of enthusiasm and commitment of an engaged team of KWS researchers and breeders to develop this strategic new approach for beet. Out of 1.5 billon individuals one single herbicide tolerant individual was naturally found, which formed the basis for the development of the new CONVISO® SMART system.

The tolerance of the new SMART KWS varieties has been obtained through a naturally occurring change in an enzyme involved in the biosynthesis of essential amino acids. Beet plants with this spontaneously changed enzyme were specifically selected and used for further breeding to develop SMART KWS varieties.
