Herbicide treatments for the control of resistant black grass (Alopecurus myosuroides Huds.) in winter wheat (Triticum aestivum L.)

Gehring, Klaus | Thyssen, Stefan
Different herbicide treatments were tested in the year 2010 – 2013 at eight locations in the north-west of Bavaria in Franken to control herbicide resistant black grass (Alopecurus myosuroides, Huds.). Application of Atlantis (Mesosulfuron + Iodosulfuron + Mefenpyr) was essential for the control of black grass in winter wheat. Combination with other herbicides was also in focus of the trial program as different treatment methods, application timing, application sequences, herbicide rate and the use of adjuvants. As a result of the trials sequence applications were more effective than single applications. The use of soil active herbicides in autumn and spring application of Atlantis was one of the best solutions to control resistant black grass in winter wheat. Reduced rate of Atlantis have to be compensated by addition of appropriate adjuvants. Higher level of resistance depends on implementation of integrated weed management to serve economic wheat production.
