Abstract

The present experiment was conducted to evaluate the efficacy of three chemical fungicides i.e., Cupravit, Ridomil and Dithane M-45 and cow-urine on seeds of two wheat varieties as Prodip and Akbor. Through seed treatments Bipolaris sorokiniana, Aspergillus sp., Trichoderma viride, Penicillium sp. and Rhizopus sp. were detected by blotter method from the tested wheat seeds.Tested with fungicides and cow-urine remarkably increased the germination rate and also reduced seed associated fungal incidence over control. Higher seed germination (100%) was found at 2500 ppm of Ridomil in Prodip variety where 98.67% was in Akbor variety with Cupravit and Ridomil. Cow-urine also increased seed germination (36.99%) at 75% concentration. At 1500, 2000 and 2500 ppm of Cupravit, Ridomil and Dithane M-45 showed promising results to eradicate (100%) all associated fungi in both varieties. Moreover, among the three fungicides Cupravit had shown the best effect reducing seed associated fungal infection. Beside this, 75% concentration of cow urine were successfully controlled all associated fungi from the seeds of both varieties and increased germination.
