In Mexico, manzano pepper (Capsicum pubescens) is a crop of economic importance. 2022, in the municipality Taxco de Alarcon, Guerrero, leaf spots were observed mazano crop. The fungus Alternaria spp., was consistently isolated from symptomatic pepper. A molecular characterization carried out by amplification and sequencing internal transcribed spacer (ITS) region ribosomal DNA, major allergen (Alt 1), anonymous gene (OPA10-2). BLAST analysis indicated similarity that varied 99.5 to 100% with...
Roselle (Hibiscus sabdariffa L.) is a crop of economic importance, refreshing drinks are prepared from its calyces, it also attributed to antioxidant, antibacterial, and antihypertensive properties (Da-Costa-Rocha et al. 2014).

The symptoms consisted wilting, yellowing, root stem...
Background/Objective. Diseases of agricultural crops affect the yields and quality products. Synthetic chemical compounds are generally used to control them; these cause harmful impacts environment, as well human health. In this sense, beneficial microorganisms can be in agriculture biocontrol agents, contribute obtaining food sufficient safe quantities. The fungus Irpex lacteus has been reported a potential agent. objective research work was evaluate vitro mycoparasitic capacity endophytic...
