Phyto-Fungicides: Structure Activity Relationships of the Thymol Derivatives against Rhizoctonia solani

摘要

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