Pot culture experiments were conducted under glasshouse conditions to evaluate the biocontrol efficacy of arbuscular mycorrhizal fungi viz., Acaulospora levis, Gigaspora margarita, Glomus mosseae, G. macrocarpum and Rhizophagus intraradices @ 15 g plant−1 and compared with carbofuran 3G and an untreated control. Among these, application of R. intraradices @ 15 g plant−1 was found to be effective, which enhanced the plant growth parameters by 62.3%, 47.6%, 45.3%, 56.0%, 46.2% of shoot length, shoot weight, root length, root weight and fruit weight, respectively along with 64.3% of AM colonization, increased spore load (169.3/100cc soil) and 0.55% of total phosphorus content. Soil population of M. incognita was also found to be significantly reduced by 49.4% with gall index (2.5). The effect was followed by G. mosseae, G. macrocarpum and G. margarita. However, A. levis showed the least effective against M. incognita and it was at par with carbofuran 3G application.
