The results of monitoring the distribution of phytopathogens and pests under conditions of maintaining mother plantations, improved and propagated in tissue culture, category original in the conditions of the Nizhne-Kundryuchensky sand massif in Rostov region, are presented. In the basic vineyard, conditions are met that exclude the possibility of secondary infection of healthy plants and make it possible to obtain planting material of the elite category. Vineyards have not been cultivated on these areas for at least 10 years, which reduces the risk of the presence of outbreaks of harmful organisms specific to grapes. Before establishing of the basic vineyard, the soil samples were diagnosed for the presence of harmful organisms in it. The results of the survey showed the absence of such pests in the soil as the larvae of scoops, beetles, click beetles, as well as bacterial diseases and nematodes. According to the results of monitoring observations, it was revealed that the mother plants of the basic plants of the ARRIV&W Branch of FSBSI FRANC are mainly spread by the following fungal diseases: powdery mildew, black spot, downy mildew, the intensity of which, due to regular protective treatments, did not exceed 2.5 points. The harmfulness of the main insects (leafhoppers, ticks, thrips) on the basic vineyard, is economically insignificant. Studies confirm the absence of migration of the leaf form of phylloxera. Pesticides were used during protective measures, guided by the principle of rotation of active substances and with the use of an active substance of one name no more than twice a season.
