APPLICATION OF REDUCED DOSES OF FUNGICIDES IN INTEGRATED PEST MANAGEMENT

Integrated pest management is actually the main direction taken in the cultivation of agricultural crops in the European Union. In accordance with its principles it is necessary to combine all available methods of reducing the occurrence of pests to a level where they do not cause losses of economic importance. Great emphasis is placed on the rational use of plant protection products and its selectivity. Essential is the large knowledge of the effectiveness of individual active ingredients and dosages in which they achieve the greatest efficacy. The aim of the experiment was to determine the possibility of using lower doses (than those registered in Poland) of fungicides in wheat cultivation in comparison to full doses. In BBCH 75 stage (medium milk) stem-base assessment was performed to confirm the effectiveness of mentioned above fungicides against eyespot of cereals (Oculimacula spp.) and Fusarium foot rot (Fusarium spp.). Application of fungicides in BBCH 31 stage in both doses (registered and reduced) allowed to obtain higher yields in comparison to non protected plots in two years of experiment.
