Oxyethylated glycerol fraction from biodiesel fuel system as ecological adjuvant material for herbicides.

摘要

Two new adjuvants - surfactant and oil adjuvant, based on oxyethylated glycerol fraction from biodiesel fuel production were tested. The new adjuvants were applied as a mixture with herbicide for weed control in spring and winter wheat and maize crop in Poland. As a standard, the same herbicides were applied in a tank mixed with commonly used adjuvants - surfactant (Trend 90 EC) and oil adjuvant (Actirob 842 EC and Atpolan 80 EC). Evaluation of adjuvants included determination of phytotoxicity for the crop and efficacy of weed control. Mixtures of new adjuvants with herbicides were not phytotoxic for the cultivated plants and weed control efficacy was similar to that of standard objects. The application of herbicides with adjuvants (tested and standard) caused the increase in weed control efficacy in comparison with plots, where herbicides were used alone.
