Studies conducted worldwide on different crops, including the grape, show the expansion of species variety in micropathogens through the emergence of new species in Alternaria Nees, 1817, and Fusarium Link, 1809 genera. The Fusarium pathogenic species attack grape buds and bunches and cause an average mass reduction of 12.8% to 60.3% and a bunch length reduction of 7.7% to 39.4%. This negatively affects the quality of grape products and the tradability of table grapes in particular. The Alternar
