Fruit growing
and viticulture of South Russia
Phytosanitary condition of plants
Results of experimental researches for defi-nition of biological efficiency of chemical and microbiological preparations on plum (Kabardinskaya rannyaya) against clastero-sporium carpophilum allowing for the de-velopment of a common pathogenic process are presented and the most effective ele-ments of protection systems against the pathogenic process are specified.
The specific structure and harmfulness of fungal diseases of wild strawberry are defined. Comprehensive perspective of use the of hemical and microbiological fungicides immunomodulating factors and them admixtures against fungal diseases of wild strawberry is established.
A new approach to definition determining the harmfulness of pests and diseases in vineyards is offered that allows differentiat-edly to approach to modeling systems for the protection of plantations on the basis of a phytosanitary condition of the plantation, stability of the sort, the prevailing weather conditions and type of damage the pest. Be able to do the high-quality protection of vineyards and reduce consumption of pesti-cides by 25-30%.
The data about the increase of species composition and increase the range of Phytophags order Thysanoptera, Hmptera, Lepidoptera, Orthoptera in the vineyards are presented. The most significant changes occurred in the fauna of sucking pests. The reasons for the changes are named: the introduction of planting material, adaptation to the conditions of the grape ecosystem of local fauna.
Results of research on the application of the method of cartograms for working out of adequate measures for restriction of virus infection diffusion, for allocation of the most important ways of viruses diffusion and an assessment of their basic characteristics (speed and diffusion degree, localization, transmitting agents, etc.) are given.
