SURFOM^® CS 8152 – SOLUTION FOR GLUFOSINATE COMBINATIONS

With increases in the number of existing glyphosate-resistant weeds and growth of genetically modified crops tolerant to glyphosate & glufosinate, use of herbicide combinations have grown in recent years. The level of technology in these formulations has increased, making usage safer in a wide range of crops, such as maize, soybeans, and cotton, possible.

Besides being effective in the management of glyphosate-resistant weeds, glufosinate also controls both acetolactate synthase (ALS) and triazine- resistant weeds. Paraquat replacement across certain regions of the globe has also benefited glufosinate in recent years, while particularly in the Americas, glyphosate & glufosinate combination formulations are becoming more common. The number of new products registered increased three-fold from 2017 to 2021, and the glufosinate market is estimated to be worth S$ 723 million, applied to more than 37,000 hectares. Glufosinate and its combinations play an important role in the future of the herbicide market, and development of new technologies requires careful consideration of the surfactant employed in these formulations. With this in mind, Oxiteno has developed SURFOM CS 8152.

INTRODUCTION TO SURFOM CS 8152

SURFOM CS 8152 is a novel solution developed by Oxiteno for standard load ammonium glufosinate standalone formulations and glufosinate combo formulations. Combinations of active ingredients may provide synergistic control, reducing doses and packaging in the field.

SURFOM CS 8152 is easy to handle, low viscosity and has excellent wetting and adjuvancy properties. Oxiteno developed this solution to provide improved AI efficacy in the field and an easy-to-formulate co-formulant.

The amount of the product included in the formulations depends on the final application.

Product properties are presented in the table below.
