Abstract
Objective: Evaluate in vitro plant extracts of three plant species: mistletoe (Psittacanthus spp.), skunk grass (Petiveria alliacea) and ginger (Zingiber officinale), to determine the inhibitory effect on mycelial growth of Penicilliun citrinum isolated from coffee beans.
Design/methodology/approach: Filtrations were performed under aseptic conditions using a vacuum system. These were added to the Potato Dextrose Agar medium, once solidified a 5 mm disc of P. citrinum was placed in the center of the Petri dish.
Results: The ethyl plant extracts showed inhibition of (100%) on the development of the pathogen as well as the chemical product.
Findings/conclusions: Ethyl plant extracts can be an agroecological alternative to control P. citrinum.
