CONVISO SMART is a new system to control monocotyledonous and dicotyledonous weeds in ALS-inhibitor tolerant sugar beets. This system consists of an ALS-inhibiting herbicide and a sugar beet variety which is tolerant against the complementary herbicide due to classic breeding mechanisms. The herbicide CONVISO is a combination of the two active ingredients foramsulfuron and thiencarbazonemethyl. Whereas foramsulfuron is the leaf active compound, thiencarbazone-methyl is leaf as well as soil active. The product will be formulated as an oily dispersion (OD). The registration was requested with an application rate of 1 x 1 l/ha or 2 x 0.5 l/ha in ALS-inhibitor tolerant sugar beets. Application should be done from BBCH 10 – 14 of the weeds, especially of Chenopodium album as well as from BBCH 12 – 18 of the sugar beet. The estimated introduction of this system on the German market will be 2018. CONVISO is well active against the most important weeds in sugar beets, including Polygonum and Chenopodium species. Furthermore several difficult to control weeds as Aethusa cynapium and Mercurialis annua will be controlled by CONVISO. The addition of special herbicides to control those difficult weeds will no longer be necessary. The tolerance of the variety against CONVISO is very strong, which will be shown by the results of the weed free selectivity trials. Due to the high tolerance of the variety against CONVISO and the not occurring of negative herbicide effects, the full yield potential can be utilized.
