Abstract :

Fungicidal evaluation for new ten benzimidazole derivatives, belonging to three different functional groups attached to C-2 of benzimidazole ring system, was carried out in this study aginst four pathogenic fungi. The tested fungi are Rhizoctonia solani, Fusarium oxysporium, Botrytis allii and Aspergillus niger. Some of the investigated compounds possessed promising antifungal activities. Structural activity relationship was discussed in this work. The most reactive derivative was formulated in the form of 10% Emulsifibale Concentrate (EC). The new formulation was re-evaluated and its activity was compared with the standard fungicide. Field performance efficacy of the local formulation against some pathogens that cause bulb rotting of onion during storage was also investigated. Data obtained under laboratory conditions showed that, some new benzimidazoles possessed high biological impacts. Local formulation showed also higher activity than that of the standard fungicide under laboratory and field conditions. 

Keywords :
