Abstract
Due to the steadily increasing cost of weed control in corn (Zea mays L.) and possible negative impact of chemicals on environment the demand for less and more efficient herbicide use is rising. Field studies were carried out in 2010 and 2011 in the Middle-West Poland in order to assessment the effective weed control. Treatments included herbicides tembotrione and flufenacet + isoxaflutole at recommended (88.0 and 36.0 + 7.5 g ha -1 ) and reduced rates (44 and 22 g ha -1 ; 19.2 + 4.0 or 9.6 + 2.0 g ha -1 ) with addition of methylated seed oil (MSO) and ammonium nitrate (AMN) adjuvants. Tembotrione was applied once at the stage of 3-5 maize leaves and flufenacet + isoxaflutole once at pre-emergence of maize. Mixtures of these herbicides were applied sequentially post-emergence, at 16-20-d intervals, after successive weed emergence. Results indicate that herbicide applied at reduced rates with adjuvants provided satisfactory weed control in maize. Application of reduced rates of tembotrione (44 and 22 g ha -1 ) and especially mixture of tembotrione with flufenacet + isoxaflutole and MSO + AMN adjuvants applied twice provided similar grain yield of maize as from treatments where tembotrione or flufenacet + isoxaflutole herbicides were applied only once at recommended rates (9.5, 9.7, and 10.0 t ha -1 , respectively).
