Abstract	There are several field problems of crop 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 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 rhizoplane of Spinacia oleracea L. (Spinach) as test material. There was positive effect of Neem cake in controlling fungi and actinomycetes, the bacterial populations were higher during Kharif season while fungi and actinomycetes populations were higher in Rabi season. Neem oil sprays were more effective in Rabi than in the Kharif. There was decrease in bacteria and actinomycetes populations when the plants were treated with Neem oil. Turmeric was effective in reducing the population levels of fungi and bacteria. On an average Bavistin was effective only on bacteria in reducing their population levels.
