The strategy of modern plant protection at intensive grain production

Nowadays integration of plant protection involves scientifically based application depending on a specific agroecological and phytosanitary situation of a combination of four main methods of management of a number of harmful organisms in the agorocoenosis - immunogenetic, agrotechnical, chemical and biological ones. The ecological safety of technologies provides application of the protective measures which are not only safe for a person and environment, but also play a role of nature protection factors (increase in soil fertility, conservation of useful microflora, entomofauna, phytofauna, improvement of environmental conditions). The economic rationale of the system is defined by its efficiency and recoupment. The time when the application of agronomic practices, technologies and systems was unreasonable is a thing of the past. In this regard, by the example of grain crops we considered a concept, methodological approaches and practical results of the creation of adaptive integrated system of plant protection from harmful organisms in case of modern technologies of intensive crop production. The influence of plant varietal features, soil preparation, weather factors, infectious potential of diseases, etc. on epiphytotic processes of diseases and the loss caused to harvest is studied. The principles, recommendations, mathematical models and computer programs allowing to create the system of adaptation (address optimization) of protective measures on the basis of phytosanitary and agroecological inspection of protected fields are developed. The results of the system tests in different regions of the country (25 experiences, 2006-2010) showed that its application provided the saving of pesticides 1.0-1.5 times, the increase in protection efficiency by 20-30%, increase in net profit 1.5-2.0 times in comparison with traditional technologies.
