Introduction of integrated plant protection on 1 January 2014 has been aimed at ensuring safety of food coming from the agricultural production process. One of the elements of providing consumers with healthy food is reasonable use of plant protection products. Right plant protection includes use of plant protection products at the optimal time, when the established threshold of economic harmfulness is reached. This purpose is served by, among other things, earlier establishment of the values of thresholds of harmfulness and decision support systems. Stand experiments on winter wheat compared use of fungicide protection according to the traditional scheme (of developmental stages), where farmers conduct spraying procedures with protection according to recommendations of decision support system. Adopting protection according to recommendations of the system enabled to reduce the prevalence of leaf and ear diseases and resulted in higher yield and thousand grain weight.

The Czech cereal market integration into the common agricultural market (EU) is studied using monthly price data for wheat and barley in Belgium, Germany, Austria and the Czech Republic in 1993 – 2010. Stability in the law of the one price (LOP) equation is studied through multiple structural breaks within the equation. The results indicate that the integration of the Czech Republic into EU cereal markets is more unstable than that of Austria (a fourth enlargement country), although there is more empirical support for the LOP when structural breaks are taken into account. The structural change also occurred in the old EU LOP equation between Belgium and Germany.
