Sensitivity of Phytopathogens of Berry Crops to Novochizol Nanopreparations In Vitro

Abstract

Fungal diseases are prevalent among agricultural plants, accounting for more than 80% of all plant diseases. Berry crops, for instance, are susceptible to several fungal infections such as smut, rust, and root rot. In certain regions, these diseases can cause crop losses exceeding 70%. The in vitro fungicidal action of Novochizol nanopreparations containing sulfur and copper against pathogenic fungi from the genera Alternaria and Fusarium was demonstrated. Analysis of the sensitivity of Alternaria tenuis and Fusarium solani to these nanopreparations revealed that Alternaria pathogens showed the highest sensitivity to preparations No. 1, No. 2, No. 3, No. 11, and No. 9. Similarly, Fusarium solani was most sensitive to preparations No. 1, No. 2, and No. 3. The sensitivity of Alternaria tenuis to Novochizol nanopreparations positively correlates with their fungicidal and fungistatic properties, with a correlation coefficient of 0.845. Conversely, the sensitivity of Fusarium solani to the same nanopreparations exhibited a weaker positive correlation, with a coefficient of 0.596.
