Plants Extract

Potato, (Solanum tuberosum (L.)) is a valuable stable food grown for its edible starchy tuber. This work was aimed to test the efficacy of indigenous plants extract for controlling wet rot disease of potato caused by Rhizopus stolonifer. The fungi was isolated from decaying bread and grown on potato dextrose agar (PDA) plates. Ripe Ginger (Zingiber officinale) (rhizome), West African pepper (Piper guineense) flower, Clove (Syzygium aromaticum) seed were collected from Muda Lawal Market, Bauchi, Nigeria. The dried seed were grinded using blender to get ginger, clove and West African pepper powder. Radial mycelia growth of Rhizopus stolonifer varied significantly (p≤0.01) with the application of different plant extracts. Mycelia growth of Rhizopus stolonifer was found to be low in potatoes treated with West African pepper (0.26 cm) than those treated with ginger (0.32 cm) and clove (0.33 cm). However, as observed from the result, ginger and clove did not differ statistically in their effect on Rhizopus mycelia growth (in vitro) but showed a better effect than the control treatment (0.40 cm). Inhibition of the mycelia growth by the West African pepper seed extract is an indication that it is fungicidal.

Rot Disease

Nine isolates of Trichoderma spp. were isolated from different agro- ecological regions of Nepal viz; Jumla, Palpa, Chitwan, Tarahara, Banke, Illam and Salyan and screened against Sclerotium rolfsii Sacc. Adreded soil borne phytopathogen causing collar rot of chickpea in chickpea; In-vitro efficacy of nine fungal antagonist (Trichoderma spp.) against Sclerotium rolfsii were screened. Pot experiment was done to find out the effective management of S. rolfsi through Tricoderma using different methods i.e. Seed treatment, soil drenching and soil application. All the tested isolates of Trichoderma spp. were found effective on mycelial growth inhibition and sclerotial parasitization of S. rolfsii. Trichoderma isolated from Palpa district showed maximum growth inhibition (%) of pathogen periodically after 48(93.78%), 72(96.00%), 96(97.96%) and 120(100.00%) hours of inoculation. Parasitized sclerotium showed minimum sclerotial germination on agar plates. Moreover, Trichoderma species isolated from Palpa districts showed second best percent mycelial growth inhibition periodically at 72(25.00%), 120(29.16%), 168(29.16%) and 216(29.16%).In pot experiment at 40 days after sowing, Seedling height was maximum in soil drenching with 30g per 100ml of water (22.27cm) and Mortality percentage of seedlings was least or highest disease control was observed in seed treated with 109cfu/ml (0.000%).

Rot Disease

Charcoal rot disease, caused by the fungus Macrophomina phaseolina, results in major economic losses in soybean production in southern USA. M. phaseolina has been proposed to use the toxin (-)-botryodiplodin in its root infection mechanism to create a necrotic zone in root tissue through which fungal hyphae can readily enter the plant. The majority (51.4%) of M. phaseolina isolates from plants with charcoal rot disease produced a wide range of (-)-botryodiplodin concentrations in a culture medium (0.14–6.11 µg/mL), 37.8% produced traces below the limit of quantification (0.01 µg/mL), and 10.8% produced no detectable (-)-botryodiplodin. Some culture media with traces or no (-)-botryodiplodin were nevertheless strongly phytotoxic in soybean leaf disc cultures, consistent with the production of another unidentified toxin(s). Widely ranging (-)-botryodiplodin levels (traces to 3.14 µg/g) were also observed in the roots, but not in the aerial parts, of soybean plants naturally infected with charcoal rot disease. This is the first report of (-)-botryodiplodin in plant tissues naturally infected with charcoal rot disease. No phaseolinone was detected in M. phaseolina culture media or naturally infected soybean tissues. These results are consistent with (-)-botryodiplodin playing a role in the pathology of some, but not all, M. phaseolina isolates from soybeans with charcoal rot disease in southern USA.
