Assessment of Selected Organotin Complexes against Plant Pathogen Fungi
نویسندگان
چکیده
Organotin complexes were screened extensively in vitro against a number of plant pathogens, which are responsible for various diseases in plants. Antifungal activity was determined in 2007 by Hanging drop method (in C. glocosporiodes, A. brassicicola and C. capsic) and found to be very much active in this respect. The order of increasing activities is schiff base<Et3SnL<Bz3SnL<Ph3SnL. The results provided evidence that the studied complexes have a potential to be used as drugs and these would further enable us to evaluate their utility in agriculture. The present results will add new information to synthesize antifungal drugs as the synthesized compounds showed promising antifungal activity.
