Efficacy of phytoextracts, essential oils, homeopathic drugs, organic amendments and fungicides for the management of pigeonpea wilt
Keywords:Phytoextract, essential oils, Homoeopathic drugs, organic amendment fungicides, pigeonpea wilt and Fusarium udum.
AbstractPhytoextract, essential oils, homeopathic drugs, organic amendment and fungicides were evaluated in vitroÂ as well as in vivo against Fusarium udum the causal agent of pigeonpea wilt. Among the phytoextract,Â maximum radial growth inhibition (71.0%) of F. udum was recorded with Allium sativum at 10 %Â concontration after 120 hrs in vitro and maximum disease control (31.6%) in seed treatment. The oils ofÂ Eucalyptus citridora and Cymbopogon flexuosus showed inhibition zone and inhibited the growth of F. udumÂ by 15.6 and 11.6 % after 120 hrs of incubation, respectively whereas maximum disease control (33.2%)Â was recorded with E. citridora oil seed treatment. Acid nitric 30 potency at 500 Âµg/ml concentrationsÂ inhibited 64.6% mycelial growth of F. udum and recorded maximum disease control (35.5 %). The growthÂ inhibition of F. udum with different organic amendments ranged from 1.06 to 5.51 per cent after 120 hrs ofÂ incubation. Mustard cake was found to slightly promote (-1.26%) the growth of F. udum. Soil applicationÂ of Karanj cake resulted in 40.3% disease control followed by vermicompost 33.22 %. Among the fungicide,Â carbendazim, carbendazim + mancozeb and carboxin + thiram completely (100%) inhibited the radialÂ growth of F. udum at 1000 Âµg/ml and minimum wilt incidence (27.08%) and maximum disease control wasÂ recorded in seed treatment with carbendazim.
