Abstract	There are several field problems of crop plants and vegetable plants effecting yield potential which include pests and diseases. Most of the diseases in plants are caused by microorganisms such as fungi. bacteria and actinomycetes The microorganisms are known to interact with each other and with the host plant simultaneously, sometimes resulting in useful effects on the host plant and at other times causing disease conditions. The microbes are known to colonize diverse habitats and substrates including plantsThe colonisation of different microorganisms on the same leaf offers interesting study related interaction of microorganisms and host plant under constantly changing atmospheric conditions and the host plant. During their life cycle both the host and the pathogen are subjected to several biotic and abiotic factors. The information on microbial ecology of aerial parts and other ecological niches of vegetable crops will help in understanding quality product, production thresholds, pre and post-harvest pathology and bio-deterioration. Such studies are important in understanding pathogenicity and control of plant pathogens. An attempt is made to understand the use of different biologically active fungicides and chemical fungicide on fungi. bacteria and actinomycetes populations in different ecological niches of Spinacia oleracea L. (Spinach) as test material. A comparative study of effectiveness of the biological fungicides- Neem cake. Neem oil and Turmeric and chemical fungicide Bavistin shows that while all the fungicides reduced the microbial populations over the season; Neem cake, Neem oil and Turmeric appears to be more effective than Bavistin in respect of reducing the Bacterial and Actinomycetes populations. Compared to the Control all the fungicides were ineffective in reducing the fungal populations. This also indicates biological fungicides - Neem oil, Neem cake and Turmeric are equally effective.
