Abstract:

Thymol, the key component of the thyme oil and its derivatives were evaluated for their structure activity relationship as fungicide against Rhizoctonia solani. Since plant-based chemicals are considered as “Generally Recognized as Safe” (GRAS) chemicals, there is great potential to use those and synthetic derivatives against R. solani and other fungal pathogens, in vitro, and in the?greenhouse or field conditions. Among the six thymol derivatives evaluated, thymol acetate was considered as the most suitable commercially viable plant-based fungicide due to its superior efficacy as well as lowest residue.
