The efficacy of new herbicide BAS 812 00 H (tritosulfuron + florasulam) in winter cereals

摘要

Field experiments were carried out in 2010-2011 at the Research Station in Chylice. The objective of this study was efficacy of new herbicide BAS 812 00 H (tritosulfuron + florasulam) used against weed control in spring in winter cereals (wheat cultivar Ludwig and Muszelka, triticale cultivar Grenado and Alekto, rye cultivar Dańkowskie Diament and Caroass and barley cultivar Sigra). The herbicides were applied in the spring at tillering of winter wheat and triticale (BBCH 21-27) and at the shootinggrowth stage of winter wheat, triticale, rye and barley (BBCH 33-37). In all experimental variants the same herbicide treatments and doses were used. The standard herbicides at field experiment were Mustang 306 SE (tillering growth stage) and Starane Super 101 SE (shooting growth stage). Weed infestation in cereals depended on growing plant species and cultivars. In cereals the dominant weed species were: Viola arvensis, Stellaria media, Galium aparine and Matricaria inodora. Herbicide BAS 812 00 H efficiently controlled the most of dominant weed species. The lowest efficacy was observed in controlling V. arvensis, Geranium pusillum and Veronica spp.
