Serhiyenko Y. Potato productivity when using preparations of protective-stimulating action in the growing technology in the conditions of Polissia of Ukraine

Subject of research - ontogenetic processes of potato productivity formation and realization under the influence preparations of protective-stimulating action at the treatment of planting potato tubers and haulm. Purpose of researches - the development and improvement of practices of the increase in potato productivity by means of the planting tuber and haulm treatment with preparations of protective-stimulating action. The research methods are field, measuring and weight, morphophisiological, chemical, mathematical and statistical, comparative and computation. The positive effect of tuber and haulm dressing in the vegetation period with certain preparations and that of their combinations on potato growth and development is established. This reduces the plant and tuber affection by diseases, increases yields and product quality. The best results are obtained when treating the seed material with the mixture of Prestige, 29% tiameoksam and Mikom and double spraying of haulm with fungicide Akrobat MZ, 69% imidacloprid. The components potato growing technology are improved by the application of preparations of protective-stimulating action what promotes the increase in crop productivity 1.8 fold. The research results are introduction in the Borodyanka district of the Kyiv region in 2003 - 2005 over an area 30 ha. The field of application - agricultural production.
