Herbicidal composition comprising glyphosate, glufosinate or their salts

The present invention relates to a herbicidal composition which comprises:a) at least one herbicide A selected from glyphosate, glufosinate and their salts, andb) a herbicide B which is 3-[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)pyrazol-4-ylmethylsulfonyl]-4,5-dihydro-5,5-dimethyl-1,2-oxazole [common name: pyroxasulfone].The present invention relates in particular to a herbicidal composition comprising:a) at least one herbicide A selected from glyphosate, glufosinate and their salts,b) a herbicide B which is 3-[5-(difluoromethoxy)-1-methyl-3-(trifluoromethyl)pyrazol-4-ylmethylsulfonyl]-4,5-dihydro-5,5-dimethyl-1,2-oxazole [common name: pyroxasulfone], andc) at least one further herbicide C, which is selected from the herbicide groups C.1 to C.8:C.1 herbicides of the group of acetolactate synthase inhibitors (ALS inhibitors),C.2 herbicides of the group of protoporphyrinogen oxidase inhibitors (PPO inhibitors),C.3 herbicides of the group of auxines,C.4 herbicides of the group of 4-hydroxyphenyl-pyruvate-dioxygenase inhibitors (HPPD inhibitors),C.5 herbicides of the group of phytoene desaturase inhibitors (PDS inhibitors),C.6 herbicides of the group of photosystem II inhibitors (PSII inhibitors),C.7 herbicides of the group of microtubulin inhibitors, andC.8 herbicides of the group of inhibitors of the synthesis of very long chain fatty acids (VLCFA inhibitors).
