Edible oil economy of India is primarily dependent upon groundnut production. Among the various reasons attributed to low productivity, diseases are a major constraint (Ranjan, 1973). The important fungal diseases are stem rot & leaf spots of groundnut. Recently tank mix fungicide is in use to control multiple diseases (Campbell et al. 2010). Bio-efficacy of pre-mix fungicides Lustre 37.5 SE @ 320, 480, 640 and 800 ml/ha against the stem rot & leaf spots pathogens were conducted. Best result was obtained in reducing both the diseases and minimum disease severity 2.75% (stem rot) and 11.77% (leaf spots) was observed at higher dose of Lustre 37.5 SE at (800 ml/ha) statistically at par with the application of lower dose (640 ml/ha). Lustre 37.5 SE was not phytotoxic even at higher dose (960 ml/ha).Dose recommendation was 640 ml/ha which was cost effective. Different growth characters and yield parameters were also increased due to application of above dosages of Lustre 37.5 SE.ReferenceRanjan, S.S. (ed), 1973.
