Potential of probiotics in the control of coffee leaf rust

Abstract: Considering the benefits that probiotics confer on the health of various hosts, as well as the availability of commercial products in the global market, this study aimed to evaluate the potential of probiotics in controlling coffee leaf rust caused by Hemileia vastatrix. We evaluate the potential of Colostrum™ BS Liquid, Colostrum™ BS Powder, Colostrum™ BIO 21 Liquid, and Colostrum™ BIO 21 MIX Powder (designed for animal use), along with Enterogermina™ (designed for human use), in inhibiting the germination of H.
vastatrix uredionospores, and in controlling coffee leaf rust in coffee seedlings. The
probiotics Colostrum™ BIO 21 Liquid, Colostrum™ BIO 21 MIX Powder, Colostrum™
BS Powder, and Enterogermina™ inhibited the urediniospores germination in 100 %, 31.1
%, 23.0 %, and 14 %, respectively. Colostrum™ BS Powder reduced the severity of coffee
leaf rust by 77.6 % and 98.5 %, while Colostrum™ BIO 21 MIX Powder reduced the
severity by 77.6 % and 78.8 % and 87.5 % in two different experiments.
