  The weekly survey carried out from first week of October to fourth week of January, 2008-09, revealed that the maximum disease incidence of Penicillium rot was observed to the tune of 4.93, 4.35 and 2.89% at Vegetable Market, Juni Shak Market, Station Road, Anand and Horticulture Farm Shop, A.A.U., Anand, respectively. The disease incidence of various rots (Penicillium, Alternaria, Colletotrichum, Aspergillus, Phomopsis and other rots) were found maximum at Vegetable Market and Juni Shak Market, Anand than the Horticulture Farm Shop, Anand. The pure culture was obtained from surveyed of aonla fruit and sent for identification to Indian Type Culture Collection (I.T.C.C.), Division of Mycology and Plant Pathology, I.A.R.I., New Delhi and was identified as a new recorded the Penicillium funiculosum (ITCC: 7046.08).

  The present investigation on was undertaken in the Department of Plant Pathology, B.A. College of Agriculture, A.A.U., Anand. The Penicillium funiculosum rot of aonla was found a new record in Gujarat and it was identified by Division of Mycology and Plant Pathology, Indian Agricultural Research Institute, New Delhi (ITCC No.: 7046.08). Bio-efficacy of nine phytoextracts at 10% were tested against the mycelial growth and sporulation of Penicillium funiculosum in vitro, among them significantly lowest mycelial growth of P. funiculosum was recorded in neem leaf extract (7.75 mm) showing 89.49% growth inhibition. Further it was also proved most effective in reducing the Penicillium rot severity both in pre- (20.44%) and post-inoculation (20.87%) treatments at 7 day after inoculation, respectively. The next best treatment in tested phytoextracts tulsi and garlic were found both in in vitro and in vivo condition.

  To encounter the acute shortage of properly decomposed organic manure the present study was conducted for investigating the pattern of decomposition of the temple waste. Isolation of the fungi from decomposing temple waste and soil mixed with manure was done by direct observation method, damp chamber incubation method and dilution plate technique. Total 28 fungus were isolated and highest fungal population was recorded by dilution plate technique followed by damp chamber and then direct observation method and according to their occurrence they were divided into three categories (1) Dominant fungi which show 70% frequency, (2) Common fungi which shows less than 70% frequency and (3) Rare fungi were observed once or twice during isolation. The moisture content of the decomposing temple waste recorded maximum 29.65% at 15 days of intervals. Deuteromycotina fungi were recorded highest 64.28% in comparison to Zygomycotina (7.14%) and Ascomycotina (3.5%). In early stages of infection Mucor racemosus, Rhizopus nigricans Alternaria alternata, Fusarium spp. were found abundantly but in later stages of decomposition prevalence of Aspergillus niger, Aspergillus flavus, Aspergillus fumigates, Aspergillus candidus, Penicillium rubrum, Penicillium citrinum was recorded. During the process of decomposition the moisture content of the temple waste gradually decreases whereas changes in pH follow an erratic pattern due to the activity of above mentioned mycoflora throughout the process of biodegradation.
