Description Role of actinomycetes in plant growth promotion and biocontrol are getting new insights as better alternative for sustainable agriculture production over agro-chemicals. Composts prepared using widely avail¬able herbs can be rich in actinomycetes with agriculturally beneficial traits such as siderophore production, chitinase production, and suppre¬ssion of disease causing fungi. Selection of novel, active actinomycetes can be done by examining microbial rich natural sources like composts and organic amended agriculture soils. Twenty nine different herbal plants foliage (with properties to help manage insect-pests) was used to prepare vermicompost in 12" d plastic pots and were used as source to isolate actinomycetes. Some of these isolates were present in large numbers (105 per g compost). Actinomycetes (136) were isolated,purified and further studied for plant growth promoting traits on different media and anti fungal activity against plant pathogenic fungi. The results indicated that 73%, 37%, and 53% were siderophore, chitinase and protease producers respectively whereas none of the 136 isolates were able to solubilize rock phosphate. Bio control studies indicated that 79%, 53% isolates inhibited Macrophom.ina phaseolina and Fusarium. oxysporum. f. sp. Ciceri respectively. Regular and liberal use of composts, prepared from these botanicals would highly likely enhance soil health
