Fr., the anamorph of an ascomycete fungus (<em>Botryotinia fuckeliana</em> Whetzel). Locality Smilica, Kavadarci, Republic of North Macedonia, was the place where experimental fields with white varieties Smedervka and Zilavka were continuously observed. Working hypothesis was to follow development of the disease after increasing glucose over 11% until the time of the grape harvest, and microclimate was monitored at the same time. In both white varieties Smederevka and Zilavka on the control variants weren’t used botricide treatments to distinguish between the variants that were conventionally treated against <em>B. cinerea</em>. The aim of the research was to determine how microclimatic conditions affect the development of <em>B. cinerea</em> and consequently to create forecasting model for gray mold. The forecasting model for <em>B. cinerea</em> is based on relationship between temperature and humidity in the vines’ canopies. The aim of the research is to prevent development of <em>B. cinerea</em> and consequently reduce the number of chemical treatments.展开更多
