Fertilizers based on complexes of chelated trace elements are the most common and effective agricultural products for the induction of protective-compensatory and other adaptive reactions of plants. The influence of various leaf treatments technologies with chelated micronutrient fertilizers application on the stability of grapes is studied under increasing abiotic and biotic environment factors within the Taman Peninsula (Russia) considering the content of proline, photosynthetic pigments (chlorophylls and carotenoids), total water in the leaves, as well as the development of infectious drying of clusters and leaf spotting reduction due to the treatment. The new optimized scheme application on the chelated micronutrient fertilizers showed a predominantly positive effect on the grape plants adaptation to high-temperature drought and fungal diseases susceptibility, as well as essential increase of the average cluster weight and yield per hectare.
