Fruit growing
and viticulture of South Russia
The description of the signs of defeat of grape plant mildew is resulted and the basic agricultural practices to combat it used in production are listed. The chemical method presented fungicides of contact and systemic action is described. The data maintenances of residual quantities of preparations of group of copper and dithiocarbamate in grapes of table and technical direction are shown.
Tasks for basic research of transformation of triazoles on vineyards are to determine the mechanisms of biochemical process of their accumulation, translocation and degradation of ecosystems soil grapes. To this purpose, fungicidal heterocyclic compounds with three or more heteroatoms in the cycle chromatographic identification of triazoles and their toxic products of metabolism is executed. The article presents the results of the identification of triazoles in the soil and grapes, performance criteria for the identification of fungicides obtained an improved method of research.
Results of complex agrotechnical and ecologo-toxicological researches in viticulture are presented. A positive role of new agricultural practices of activation of living ability the soil microflora ampelocenosis to accelerate the degradation of pesticides by organic fertilizer and effective microorganisms is defined.
The results of studies on the effect of post-harvest handling biological products for storage of apples are presented. It is established that the use of antioxidants of guanidine in storage of apple fruits in coolers reduce losses and extends the qualitative state of the fruit.
The results of long-term work on the selection of the apple rootstocks adapted to the conditions of Southern horticulture are presented. The morphological description and the main economicallyvaluble characteristics of apple rootstocks series SK (North Caucasus) SK 2U, SK 3, SK 4, SK 5, SK 7 are given.
