New herbicide in Argentina combines 2 molecules, 1 unprecedented

The multinational Sumitomo Chemical announced the launch of Terbyne Max, a pre-emergent herbicide formulated based on flumioxazin, a molecule discovered and developed by the Japanese agrochemical company.

The product also has in its formulation another new active ingredient: terbuthylazine.

The corn campaign is already in full swing in Argentina, but many lots are still implemented “lately”. These crops need special attention to prevent the proliferation of weeds before the sowing season arrives.

“The advantage of this combination is that by incorporating flumioxazin, a product belonging to PPO herbicides, it achieves a differentiated treatment, as it incorporates an alternative mode of action in the pre-emergence segment of corn. This gives the possibility to rotate the tools more and better, and thus better manage the problem of difficult weeds,” commented Lucas Díaz Panizza, Marketing Manager at Sumitomo Chemical.

According to Panizza, “The combination of active principles provides a synergistic effect, a burning effect, a greater control spectrum, and greater residuality, even in combination. with other herbicides, such as hormonal ones, graminicides, such as S-metolachlor, or desiccants, such as paraquat, with which it has excellent compatibility.”

Furthermore, due to its formulation, it is very simply incorporated into the soil with little rainfall, a situation that its competitors do not face. It is a fundamental factor in this season in which the La Niña phenomenon develops with below average rainfall conditions.

Another differential is the flexibility of use, as it has a wide range that allows it to be used throughout the year, following the recommendations, in different vintages, without problems. For example, Sumitomo Chemical positions Terbyne Max as “the new force for its corn.”

According to Díaz Panizza, the recommended dose is two liters per hectare, with the addition of 1.3 liters of Chronatol (S-metolachlor). Its application is recommended for up to ten days before corn sowing. Its control spectrum is broad: it is registered for Conyza (black branch), Amaranthus, Parietaria, and other weeds (Echinochloa, Eleusine, Lolium, Chloris) and cruciferous (Brassica).

According to the conducted tests, Terbyne Max generally achieves more than 80% control within 60 days of application, which is a significant difference compared to products in the same market segments.
