Long-term use of herbicides based on pendimethalin, prometrin on vegetable and field crops contributed to the accumulation in agrocenoses of resistant weeds from the aster (Ateraceae), cabbage (Brassicaceae) families, as well as black nightshade (Solanum nigrum L.), upturned acorn (Amaranthus retroflexus L.), and tenacious bedstraw (Galium aparine L.) and reduced their effectiveness. The problem of expanding the range of herbicides on garlic with highly effective preparations of a wide spectrum and different mechanisms of action predetermined the carrying out of researches in 2021–2022 at the ARRIVG – branch of FSBSI FSVC (Moscow region, Ramensky district). Purpose of the research: assessment of the biological effectiveness and selectivity of herbicides not registered on garlic plantings: Butizan 400, SC, Bandur, SC and Estamp, EC of the tested preparations, the greatest effectiveness was ensured by the spring application of Butizan 400, KS at a rate of 2 l/ha in the phase of 2 garlic leaves. The herbicide suppressed 88–96% of annual dicotyledonous weeds, reducing their weight by 92–97%. The hard-to-eradicate weeds of common groundsel (Senecio vulgaris L.), common chickweed (Stellaria media Vill.), small-flowered galinsoga (Galinsoga parviflora Cav.), garden sow thistle (Sonchus oleraceus L.), field grass (Thlaspi arvense L.), shepherd's purse (Capsella bursa-pastoris Medik.), black nightshade (Solanum nigrum L.) and upturned acorn (Amaranthus retroflexus L.) were highly sensitive to it. Tenacious bedstraw (Galium aparine L.) showed less sensitivity. The condition for highly effective application of the herbicide Butizan 400, KS is its application on moist, fine-lumpy soil followed by precipitation (10–15 mm) or watering (150 m3/ha) within a week after treatment. The largest and most reliable increase in garlic yield (1.3 t/ha) was achieved in the variant of early spring application of Butizan 400, KS 2.0 l/ha. Herbicides Butizan 400, KS, Bandur, KS and Estamp, CE did not have a phytotoxic effect on garlic during the growing season and were selective towards it.
