During 2007 and 2008 examinations with some herbicide variants (Pendimetalin, Trifluralin, Metribuzin and Metribuzin+Quizalofop-p-ethyl) and one control variant (untreated) were conducted on the experimental field of UGD, Faculty of agriculture – Strumica, to determine the efficacy of some herbicides (Pendimetalin and Trifluralin) in destroying weeds in pepper, and some herbicides (Pendimetalin, Metribuzin and Metribuzin+Quizalofop-p-ethyl) indestroying weeds in tomatoes, grown as summer crops in greenhouses. The weed vegetation in the experiment was consist of eight species, of which dominant were: Portulaca oleracea L. with 47, 5 plants/m2, Echinochloa crus galli L. (32, 5) and Galinsoga parviflora Cav. With 9,5 5 plants/m2. The weeding on the experiment is relatively
high and is in average, 108 plants/m2. The efficacy of the herbicides in destroying the weeds in the two year of the examinations in all herbicides and herbicide combinations is relatively high, and the coefficient of efficacy at the most variants is more than 92 %. Although used in greenhouses, neither one of the herbicides showed phytotoxic effect on the crops.
