Tebuconazole 250 EC (4.78% urediniospores germination) was found to be significantly superior among the eight systemic fungicides evaluated in vitro condition against Puccinia sorghi at different concentrations. Among the non-systemic fungicides Mancozeb + Phyton (7.24% urediniospores germination) was found to be significantly superior followed by Mancozeb (24.44% urediniospores germination) at different concentrations screened in vitro. The fungicides revealed higher efficacy with the increase in concentration levels. Among the botanicals tested, Neemazol F5% caused significantly less percent spore germination (6.55%) followed by Nimbicidine (6.83%) at different concentrations and Trichoderma harzianum at  108spores/ml was recorded significantly less percent germination (31.07%) followed by Bacillus subtilis(43.42%) and Pseudomonas flourescens (53.39%) evaluated in vitro condition against P. sorghi at different concentrations. Jeevamruta at 20% concentration caused significantly less percent germination (22.69%) followed by Panchyagavya at 20% (33.67%).
