The effectiveness of herbicides (Stomp 3, 4 and 5 l/ha, Harnes 1.5, 2.0 and 2.5 l/ha, Topogard 2 and 3 kg/ha, Gesagard (standard) 2 kg/ha, Basagran M and time of harrowing in the stand of semi-leafless pea variety 'Odin' was investigated at the Kaltinenai Research Station of the Lithuanian Institute of Agriculture on soddy-podzolic loamy soils of hilly relief over 1995-1997. The results show, that even twice harroving the stand of pea, as an ecological measure, was not sufficiently effective in controlling weeds, because of the low ability of the crop to compete. Twice harroving the stand of pea, i. e. before emergence and in the stage of 3-5 leaves, reduced the weediness evidently, but not enough. All the herbicides used have reduced weediness (47.2-89.8) better than harrowing (2.9-15.9). The most sensitive weeds to herbicides were the annual dicotyledonous ones. The best action on killing of weeds and yield of pea increase was registered Stomp 4 l/ha application
