List of Producers and Formulators of Commercial AM Inoculum

These bio-inoculants are now formulated in different formulations. These are designed on the basis of their application to different crops and locations. They are available in the form of powders, tablets/pellets, gel beads, and balls. Intraradical forms of Glomus sp. (vesicles and mycelium fragments) were entrapped in alginate and used as inocula. Isolated intraradical material was found to regenerate in alginate beads and the regenerated mycelium infected roots under controlled conditions (Declerck et al. 1996a,b; Strullu and Plenchette 1991). Glass beads have also been suggested an inoculum type with spores and mycelia inside (Redecker et al. 1995). The application in nursery plantations is normally done using pellets or tablets placed just below the seeds or small plantlets initiating mycorrhization in the hardening phase. Alternative approaches for inoculum disbursement include broadcasting in the field or mycorrhizal products often contain other ingredients designed to increase

the effectiveness of the mycorrhizal spores. For example, organic matter is often added to encourage microbial activity, soil structure, and root growth. Stress vitamins improve nutrient uptake and build root biomass. Water absorbing gels help "plaster" beneficial mycorrhizal spores in close proximity to feeder roots and encourage favorable soil moisture conditions for mycorrhizae to form and grow. Organic biostimulants, in general, are effective ingredients in mycorrhizal products. By promoting field competitiveness, stress resistance, and nutrient efficiency, biostimulants reduce barriers to rapid mycorrhizal formation especially during the critical period following root initiation or transplanting. A list of commercially available mycorrhizal inocula is provided in the table above.

Recent advances in the in vitro mode of mass multiplication like optimizing various growth parameters like pH, media manipulations (Douds 2002) can further increase the recovery of propagules. Recent report on the success of co-culturing two different genera together with single host under in vitro as it occurs in nature, opens a new scope of an in vitro consortium package as inoculum, which may prove more superior in varied edapho-climatic regions where multiple mycorrhizal isolates may function better than single isolate inoculation for future (Tiwari and Adholeya 2002). Industry-based research documentation's as such are not available to the end users but a recent brief insight into some of the potential techniques by Moutoglis and Beland (2001) along with other alternative production techniques such as bioreactor-based production techniques proposed by Jolicoeur et al. (1999); Jolicoeur and Pirrier (2001) making use of ROC proposes a bright future for AM biofertilizer.
