Abstract
A national survey was conducted in Finland from 1982 to 1984 to determ ine the main weed species in spring cereals and the efficacy of herbic ides on Finnish farms. The most common dicotyledonous weeds producing the highest biomass in spring cereals were Chenopodium album L., Galeo psis spp. L., Stellaria media (L.) Vill. and Lapsana communis L. The m ain grass weed was Elymus repens (L.) Gould. The average reduction of weed biomass by herbicide treatment was 75%. More reliable efficacy wa s obtained with herbicide mixtures than with MCPA alone.
