An experiment was conducted under field conditions to observe the effect of bio-agents, botanicals and fungicide against Phytophthora infestans. Seven treatments were taken up with three replications and data collected was analyzed using randomized block design (RBD). Two botanicals (Neem extract and Garlic extract), three bio-control agents (Trichoderma viride, T. harzianum and Pseudomonas fluorescens) and treated control were used. Minimum disease intensity percent and maximum production of tomato was recorded in treatment P. fluorescens@5g/l (33.30% and 223.10 q/ha, respectively) followed by T. viride @5g/l (34.79% and 213.36 q/ha, respectively), as compared to treated control (30.80% and 244.50 q/ha) and untreated control (55.88% and 103.50 q/ha). P. fluorescens was found significantly superior over other treatments. In other parameters, plant height (cm), fresh shoot weight (g), fresh root weight (g), root length (cm), dry shoot weight(g) and dry root weight (g)of T. viride (62.41cm, 53.30 g, 7.02 g, 22.02 cm, 8.28 g and 4.70 g respectively) shoot weight (g), fresh root weight (g), root length (cm), dry shoot weight(g) and dry root weight (g)of T. viride (62.41cm, 53.30 g, 7.02 g, 22.02 cm, 8.28 g and 4.70 g respectively) was found(best treatment) and was significantly superior over other treatments.
