RESISTANCE OF RHIZOCTONIA SOLAN! TO CERTAIN FUNGICIDES AND THEIR IMPACT ON BENEFICIAL MICROORGANISMS
Sami Shafik Ramses;
Abstract
The isolation trials were canied out from soil prepared for cotton cultivation at different locations as Basion province in Gharbia governorate and Sakha province at Kafr El-Sheikh governorate. Data indicate that several isolates of both R. solani and Fusarium monifilorme were obtained and have been tested for their sensitivity to three tested fungicides i.e., pencycuron, tolclofos-methyl and carboxin. One isolate {No2) of R. solani from Kafer El-Sheikh governorate, showed high resistance against higher concentrations (up to 1500 ppm) ofto1clofos-methyl with remarkable activity of mycelial growth on PDA medium treated with such fungicide. Acquired resistance was retained after five transfers on fungicide-free medium.
