Abstract

Results of studies with the herbicide 1-(3-chloro-4-methylphenyl)-3-methyl-2-pyrrolidinone (hereinafter referred to as BV-207) suggest that it interferes appreciably with photosynthesis. A concentration of 10-4 M of BV-207 almost completely inhibited fixation of labelled carbon dioxide by leaf disks of various plants. In addition, carbohydrates protected plants from the phytotoxic action of the chemical. BV-207 was considerably more toxic when plants received light after application of the herbicide, compared with those held in the dark. On the other hand, root growth was inhibited only slightly by BV-207.
