Three-year field experiments were conducted during kharif 2021, kharif 2022 and kharif 2023 at Pearl Millet Research Station, JAU, Jamnagar. Total five treatments [(Trichoderma harzianum (JAU @ 8 g/kg), PSB formulation (PSB 8g/kg), Neem oil (3%) and Metalaxyl (6g/kg)] including control was used as seed treatment. Seed treatment was carried out for management of pearl millet downy mildew. In 60 DAS observation shows that the Metalaxyl 35 SD (6 g/kg) recorded minimum downy mildew disease incidence (10.12%) and which was at par with seed treatment of Trichoderma harzianum (8 g/kg) (11.55%). The maximum downy mildew disease incidence recorded in control (18.58%). Maximum grain yield (2127 kg/ha) and fodder yield (38.02 q/ha) found in treatment Metalaxyl (6 g/kg) and which was at par seed treatment Trichoderma harzianum (8 g/kg) (2002 kg/ha grain yield and 36.86 q/ha fodder yield). Minimum grain yield (1418 kg/ha) and fodder yield (30.09 q/ha) recorded in control.

Downy mildew, Trichoderma harzianum, Metalaxyl

It can be concluded from the above results that the seed treatment of Trichoderma harzianum (8 g/kg) in pearl millet against downy mildew disease were found effective to minimize blast intensity, higher grain and fodder yield and additional income also
