Disease management for organic groundnut cultivation

Abstract

The major diseases on groundnut are collar rot, stem rot, late leaf spot, and rust. For the management of these diseases and to produce organic groundnut various organic treatments were imposed. The experiment comprised of eight treatments replicated thrice in design RBD during Kharif-2011 at Oilseeds Research Station, Jalgaon. The results obtained revealed that combinations like seed treatment with mixture of Trichoderma sp. and Pseudomonas fluorescens @ 10 g each / kg seed + combined furrow application of Trichoderma sp. and P. fluorescens @ 2 kg each enriched with FYM @ 300 kg/ha + foliar application of mixture of both @ 5 g each /lit (2.5 kg/ha each) at 30 and 45 DAS was recorded least incidence of seed/soil borne diseases viz., collar rot at 30 DAS (3.58%) and stem rot at harvest (5.40%) as well as foliar diseases viz., late leaf spot (6.8%) and rust (3.8%) as against control 10.85%, 14.88%, 15.6%, 11.1%, respectively.
