EFFECT OF HERBICIDES ON FLOUR QUALITY OF 2 WINTER-WHEAT VARIETIES

Two winter wheat varieties were treated with 11 different herbicides ( Belgran, Aniten D, Banvell M, Lorgan, Assert, Puma, Illoxan, IP-Flo, S tarane, Dikamin D and Dikotex 40) in field trials. The baking properti es of their grain yields (wet and dry gluten content, gluten spreading , valorigraphic value and water absorption, falling number (FN), SDS s edimentation volume) have been determined. Treatments with double dose s of herbicides modified the dry gluten content, gluten spreading, wat er absorption, FN and the SDS sedimentation volume, respectively. Cons idering the properties except for dry gluten, the interaction between varieties and herbicides seemed to be reliable, namely the quality of varieties was changed by the herbicide treatment. This variety specifi c effect of herbicides was different for every quality parameter. Out of the 11 herbicides Logran and Assert were found to be the most favou rable ones because the baking parameters have not been significantly d amaged by them, moreover they were in some cases favourably influenced .
