Control of infections caused by Alternaria alternata with Trichoderma harzianum at different stages of tomato cultivation (Solanum lycopersicum)

Abstract

Tomato cultivation is one of the most widespread in Argentina. This is affected by various diseases, including those caused by the fungal genus Alternaria. It includes pathogenic species that can infect crops from planting and even cause significant post-harvest damage. The use of phytopathogen biocontrollers is a promising tool that gained a strong boost thanks to technology and coupled with the paradigm shift in society´s consumption habits. In this work we evaluated the effectiveness of Trichoderma harzianum ITEM 3636 as an antagonist of A. alternata.
