Online published on 15 December, 2016. Abstract In present study, the efficacy of bioinoculants viz., Azospirillum lipoferum (N2 fixer), Pseudomonas striata (PSB), Mythylobacterium spp. (PPFM) and Bcillus circulans (SSB) against major diseases and sucking pest complex in cotton Cv. PH-316 was evaluated. Results revealed that all the treatments significantly reduced the incidence of major diseases a well as sucking pest complex in cotton Cv. PH-316. However, significantly least incidence of angular leaf spot (7.96%), root rot (5.24%), grey mildew (10.25%) and reddening (20.93%) were recorded with the treatment T6 (Azospirillum lipoferum + Pseudomonas striata + Mythylobacterium spp.). The same treatment also recorded significantly least populations of the sucking pests viz., aphids, jassids, thrips and white flies. The second best treatment found was (A. lipoferum + P. striata + Mythylobacterium spp. + Bacillus circulans. All the treatments recorded significant increase in seed cotton yield and were found cost effective. Thus, for economical and eco-friendly management of major diseases and sucking pest complex in cotton the bioinoculants found effective in present study could be incorporated in integrated insect pest and disease management of cotton and exploited commercially.
