The present study was planned to evaluate the efficacy of various fungicides, plant extracts, biocontrol agents and oil cakes against Macrophomina phaseolina causing dry root rot of chickpea. Among the tested biocontrol agents against Macrophomina phaseolina, T. viride was found the most effective against the fungus followed by T. harzianum, Bacillus subtalis and P. fluorescens was the least effective in reducing root rot incidence. Among the fungicides carbendazim was found most effective and recorded minimum root rot incidence. Among plant extracts, garlic extract was found most effective in reducing root rot incidence followed by neem leaf extract. In the case of organic amendments, Neem cake was the most effective in reducing the root rot incidence while wool waste and goat manure was found least effective in controlling root rot incidence.

Fungitoxic potentials of Piper guineense, Ocimum graticimum, Casia alata, and Tagetes erecta extracts in the management of postharvest fungal deterioration of cassava root were investigated. Pathogenicity tests revealed Aspergillus niger, and Trichodderma viride as causal organisms of root rot of cassava which utilized the substrate for their growth and development. A. niger was found to be more virulent having the highest rot incidence of 75% followed by T. viride which depicted a lower pathogenic effect with rot incidence of 33.3%. The result of the inhibitory potentials of the water and ethanolic extracts of P. guineense, O. graticimum, C. alata, and T. erecta against the two fungal pathogens showed significant differences (p≤0.5) in their rates of fungitoxicity on A. niger, and T. viride. The ethanolic extract of T. erecta gave the highest mean inhibitory effect of 63.8% on A. niger while the least mean growth inhibition of 9.20% was recorded by water extract of P. guineense on T. viride. The results of in vivo test of the plant extracts applied before and after inoculation with spore suspension of test fungi indicated high significant effect on the rot incidence and severity. Piper guineense water extract was less effective in controlling the development and spread of the pathogens during pathogenesis hence the highest percentage disease incidence and severity when it was applied after the inoculation with spore suspension of A. niger. The lowest incidence of rot was recorded with water and ethanol extracts of T. erecta applied before inoculation of T. viride. A. niger showed a stronger resistance to the plant extracts than T. viride in the control of cassava root rot in storage.

Efficacy of two strains of <i>Pseudomonas aeruginosa</i> (Pa-5 and IE-2) and <i>Bacillus subtilis</i> isolate alone or in conjunction with neem cake or <i>Datura fastuosa</i> was tested for the management of three soilbrne root-infecting fungi including <i>Macrophomina phaseolina, Fusarium solani</i> and <i>Rhizoctonia solani</i> and the root-knot nematode, <i>Meloidogyne javanica</i> on uridbean. Biocontrol bacteria used in combination with either neem cake or <i>D.fastuosa</i> gave better control of the root-rot and root-knot infection with the enhancement of growth of uridbean compared to the use ofeither component alone. Neem cake l% w/w mixed with <i>P.aeruginosa</i> strain IE-2 caused greatest inhibition of the root-knot development due to <i>M.javanica, P.aeruginosa</i> and <i>B.subtilis</i> used with organic amendment also increased <i>Bradyrhizobium</i>-nodules in the root system.

<p>The aim of this study was to assess fungicidal potential of homeopathic globules namely <em>Thuja occidentalis</em> and <em>Arnica montana</em> (30C) on plant growth and root infecting fungi particularly <em>Rhizoctonia solani</em>,<em> Fusarium</em> spp. and <em>Macrophomina phaseolina.</em> Both <em>in vitro</em> and <em>in vivo</em> experiments had found positive results in the suppression of root rot fungi. Investigation on present study showed that <em>A. montana</em> and <em>T. occidentalis</em> globules (100, 75 and 50% v/w concentrations) reduced disease intensity caused by root rot pathogens and improved growth of test plants, but it produces negative effects on leguminous test crops in which nodules were failing to produce.</p>
