The herbicide suppressed the formation of flowers in R. acris, L. pratensis,and V. sepium and thus, the total seed production of these three species in theherbicide treated plots was significantly reduced (Table 2). Therefore, it was notalways possible to find 48 fruits in the herbicide treated plots. We were able tofind enough fruits for harvesting in the control, insecticide, and fertilizer treat-ments.
