Efficiency of a national herbicide Sirius 400, SC (metazachlor, 400g/l) for spring and winter rape (Brassica napus) crops was investigated in the conditions of the Republic of Belarus. Weeds were presented by annual bilobed and legume weeds: winter triticale drops - 68 pieces/m2, field pansy (Viola arvensis) - 44, lamb's-quarters (Chenopodium album) - 19, corn mayweed (Matricaria inodora) - 12, shepherd's-purse (Capsella bursa-pastoris) and winterweed (Stellaria media) - 8, annual meadow grass (Poa annua). Total crop weediness was 163 pieces/ square m. Research results showed that herbicide application in doses 1,5 and 2,0 l/ha after sowing before seedlings in wet soil and at early phases of weed growth in tight soil protected rape crops against annual legume and bilobed weeds, decreased weed number till economically safe level.
