Twentyfive endophytic bacteria were isolated from internal tissues of ischolar_main and stem portions of chickpea, sunflower, niger, chilli and capsicum plants. The endophytes were screened in dual culture on Potato Dextrose Agar (PDA) and Tryptic Soya Agar (TSA) against Fusarium oxysporum f. sp. ciceri, Fusarium udum, Rhizoctonia solani and Sclerotium rolfsii. Ten isolates exhibited inhibition of the pathogens. Maximum percent inhibition (37.93) of F. oxysporum f. sp. ciceri was obtained on PDA with B. subtilis (PDBCEN 3). On TSA percent inhibition was maximum (52.21) with isolate PDBCEN-7. Testing against F. udum in dual culture test revealed that Pseudomonas sp. (PDBCEN 8) showed maximum (40.45%) inhibition on PDA. Pseudomonas sp. (PDBCEN-2) was highly effective on TSA and showed maximum (56.9%) inhibition zone. Against R. solani, maximum inhibition (44.96%) was recorded with endophyte PDBCEN 7. On TSA all the ten endophytic bacteria were effective in restricting the growth of test fungus. Percent inhibition of S. rolfsii was maximum (40.93%) with Pseudomonas sp. (PDBCEN 6) on PDA. On TSA percent inhibition was maximum (46.73%) with P. fluorescens (PDBCEN 1). The endophytic isolates were able to promote better growth of chickpea but the vigour index varied between the isolates. We could not correlate high pathogen inhibition under in vitro with high vigour index.Keywords

Eight Trichoderma isolates were tested for their bioefficacy against seed, ischolar_main and seedling rot incited by Rhizoctonia solani by adopting an in vivo test method (blotter test). Vigor index ranging from 169.5 to 2239.4 and disease incidence ranging between 10 to 86 percent were recorded in various treatments. All bioagents were graded based on disease grading key proposed for their rating. The clear differentiation of efficacy of various Trichoderma species against R. solani obtained with the in vivo bioefficacy test method adopted (blotter test) in the present study shows suitability of this method for routine screening of fungal biocontrol agents against seed and soil borne plant pathogens.Keywords

Mushrooms are the edible fleshy fruiting bodies, protein rich of prescribed fungi, which may be grown under cultivation. The most commonly cultivated mushroom species is Agaricus bisporus. Cultivated mushrooms are usually grown in the dark in climate-controlled rooms. The fungal inoculum or ‘spawn’ is added to a pasteurized substrate in growing containers or beds. After the fungal strands (mycelia) have spread through the compost, a layer of peat or soil (the ‘casing’) is added. The fruiting bodies begin appearing about 6 weeks after spawning and continue appearing in brighten up about 7-10 days apart for the next 6-8 weeks. To maintain atmospheric condition and precipitation. About one dozen mushroom species are commercially grown in the world but in Haryana state mainly only two species are cultivated which are grown at commercial level.References

A mushroom is the reproductive structure which is produced by certain fungi, its edible part is fleshy fruiting bodies which may be collected naturally or can be cultivated under c l ima t e -cont rol l ed conditions. White button mushroom (Agaricu sbisporus) is most commonly cultivated species. The fungal inoculums called ‘spawn’ (seeds of mushroom) are added to a pasteurized substrate in growing container. The fruiting bodies begin appearing about 6 weeks after spawning and continue appearing in flushes about 7-10 days apart for the next 6-8 weeks. About one dozen mushroom species are commercially grown in the world but in Haryana state mainly two species are cultivated which are grown at commercial level.References
