Title: COMBINATION OF PLANT PROTECTIVE AGENTS WITH POLYMERS THAT FORM HYDROGEN BRIDGES
Abstract:
The invention relates to the combination of an agrochemical active substance, especially herbicides from the group of the sulfonyl ureas, with a polymer while forming hydrogen bridges for the controlled release of said active substance. The polymer and the active substance have functional groups that facilitate the formation of hydrogen bridges. The preferred polymers are polyvinyl alcohols or partially saponified polyvinyl acetates.
