Conservation of natural soils supprissibility as a basic element in effective plants protection against diseases on the Black Sea coast of Russia
The review-analytical paper analyzed the materials relating to the environmental consequences of using chemical and biological plant protection products. It is shown that the intensive use of chemical pesticides and mineral fertilizers in crops cultivation has a negative effect on soil microflora. The paper also substantiated the effective principle of managing the agrocenoses resistance based on plant protection biologizing against pests. It is shown that suppressive soils, unlike conductive soils, are harmless for cultivated plants and contribute to the suppression of harmful phytopathogens.
