Results of researches carried out in 2000 and 2001 have demonstrated, that main factors determining yield of winter<br />wheat are: agrotechnical measures, mainly proper choice of field, optimal nitrogen fertilization as well as choice of<br />cultivar well adapted to local climatic conditions. Chemical protection of winter wheat affects first of all stability of<br />yield. Regular inspections of fields with special account to present phytosanitary situation, thresholds of noxiousness and<br />expected development of disease and pest populations should decide on the need of chemical treatments.
