AGROCHEMICAL IMPACTS ON QUALITY AND PESTI CIDE-RESIDUE FIGURES OF WINTER-WHEAT (TRITICUM-AESTIVUM L.)

Agronomic impacts profoundly influence the milling and baking quality of wheat. In a two-year field experiment (1996-1997) the quality param eters and pesticide residue figures of different wheat varieties were evaluated in fertilizer, herbicide, fungicide and insecticide treatmen ts. According to the experimental results agrochemical treatments caus ed only minor changes in quality parameters. Wet gluten figures were s lightly reduced by herbicide, fungicide and insecticide applications, while the farinographic values were endangered mainly by in appropriat e fertilization. Varietal differences and the climatic effects of the different crop years proved to be significant. Pesticide treatments of ten resulted in detectable residue levels, but the use of the recommen ded doses and appropriate methods of application ensured food safety.
