Summary

Studies aiming at determining biological activity of propisochlor (720 ga.i./l in Proponit 720 EC) in green peas have been conducted from 1994 to 1996 at Skierniewice. The compound tested was applied pre-emergence either exclusively at rates of 1.8 and 2.16 kg ha-1or in a mixture with prometryne (1 kg ha-1) at rates of 1.44 and 1.8 kg ha-1. Best results were obtained with the mixture of both herbicides, separate applications giving lower control of weeds. The herbicides used were not phytotoxic to green peas. The yield of pods from experimental plots was somewhat higher than that from untreated plots, the differences being, however, not significant. Propisochlor may be useful for controlling weeds in green peas, especially if high infestation with annual grass weeds is observed.
