Abstract

Alternaria zinniae causes leaf spot and blossom blight in marigolds, resulting in yield losses of 50-60 % in tropical and subtropical climates. Chemical controls can have a negative influence on ecosystems and agronomic control approaches are difficult to execute change to Chemical control are highly toxic, enhance biodegradation and cause environmental pollution after repeated use. Potential adverse effects on the earth and prolonged use have prompted a complete exclusion or limited utilization of most chemicals and an urgent need for eco-friendly and efficient tools. In vitro evidence for the possible use of Trichoderma spp. for biocontrol of marigold leaf spot and flower blight has been reported in previous investiga-tions. In this study, we used a dual culture approach to investigate the antagonistic and myco-parasitic properties of 4 Trichoderma asperellum strains against Alternaria zinniae in vitro.
