Onion and garlic crops are weeded by a wide range of weed species, including annual and perennial monocotyledonous and dicotyledonous. The application of herbicides is an economical, rapid measure, which allows the cultivation of large areas and the achievement of high production yields and increased economic efficiency. Three active substances with pre-emergence application (metolachlor, pendimethalin and oxyfluorfen) and various concentrations of oxyfluorfen with post-emergence application were tested. The results showed good control of annual monocotyledons with metolachlor and good control of annual dicotyledons with small seeds, with oxyfluorfen and pendimethalin. The post-emergence application of oxyfluorfen with various concentrations controlled annual cotyledons with large seeds (Xanthium sp. and Abutilon theophrasti) but did not control perennial dicotyledonous species.
