Abstract
Production of bio vine implies application in agriculture of substances of only organic origin. Despite the mentioned, for control of powdery mildew (oidium), application of preparations of sulfur as the most efficient means in vine growing is essential up to now and in a number of countries it is regulated only by legislative framework (frequency and interval of application). For the purpose in order to settle the mentioned problem and to achieve practical results within the framework of the project of the National Science Foundation “Use of innovation methods in vine growing of Georgia” together with the Institute of Organic Chemistry we have developed the substance bentonite. Chemically processed sulfur clay particles destruct spores of oidium; they have the same effect towards mycelium as pure sulfur and additionally have a property of high adhesiveness. For the preparation of sulfur-containing bentonite were used local natural clay from Askana ore and sulfur powder. Askana clay was being modified by sulfur in the same mode as the clinoptilolite. High density powder of Askana clay render scope and spectroscopic analysis showed, that supposedly amorphous sulfur had penetrated between clay layer structure layers and had been received homogeneous nanostructured material. For the first time we have tested bentonite in laboratory conditions on aquatic vine cultures, and also practically in the experimental vineyard.
