Streptomyces ANSCa22 treatment on Rhizoctonia bataticola inoculated Soybean seeds could control Rhizoctonia bataticola infection of Soybean in pot study which was evident from the significant increase in the values of average shoot height, pod number, seed weight and plant dry weight after the treatment. Streptomyces ANSCa22 treatment of normal soybean seeds without any pathogen inoculation also resulted in positive effect on three out of four tested plant growth parameters as compared to control. Microscopic examination of Streptomyces ANSCa22 revealed typical features of Streptomyces. Partial sequencing of rRNA gene identified ANSCa22 as Streptomyces rochei. This strain was compatible with Bradyrhizobium japonicum, exhibited tolerance to calcium carbonate and calcium sulphate upto 5% concentration and indict...

R. bataticola causes many diseases in soybean. Total 21 Streptomyces were isolated from rhizospheric soil of different plants of fields in kanheri sarap. The diversity of Streptomyces was most wide in rhizospheric soil of Pomegranate. Fourteen isolates of Streptomyces exhibited zone of inhibition against R. bataticola by dual culture method. Out of fourteen, twelve isolates were isolated from soil of Pomegranate. Streptomyces ANSP2, ANSP4, ANSP12 and ANSN14 shows strong antagonistic activity against R. bataticola. These four isolates were also found compatible to Bradyrhizobium japonicum. Efficacy of ANSP4 treatment was tested on germination of soybean seed, challenged with R. bataticola. ANSP4 shows better results than chemical treated seeds.

Streptomyces ANSP4, an indigenous isolate from the rhizosphere of pomegranate from Kanheri Sarap village of Akola district, demonstrated antagonistic potential against R. bataticola by dual culture technique. When evaluated under pot culture conditions Streptomyces ANSP4 treatment of R. bataticola inoculated seeds resulted in control of R. bataticola infection as evident from the remarkable improvement in all the tested parameters of plant growth. This biological treatment was more effective as compared to Carbendazim treatment. Streptomyces ANSP4 treatment of healthy seeds promoted plant growth as compared to control. ANOVA and T test confirmed the significance of the observations. Streptomyces ANSP4 was identified as Streptomyces malachitospinus by 16s rRNA gene sequencing and found to degrade cellulose, chitin, gelatin and starch. It also exhibited varying degree of growth in neutral to al...
