Mycorrhizas are fast gaining grounds as biofertilizer. How can one successfully commercialize the propagation of these species considering the time & technical knowhow involved?
18 Inoculum Production of Vesicular-arbuscular Mycorrhizal Fungi for Use in Tropical Nurseries
This chapter explains inoculum production of vesicular-arbuscular mycorrhizal fungi for use in tropical nurseries. Under tropical conditions (poor soils, extreme temperatures and high humidity or drought, presence of many pathogens) the use of vesicular-arbuscular mycorrhizal fungi can be especially beneficial to perennial crops that are produced in nurseries and then planted in the fields. Vesiculararbuscular mycorrhizal fungi not only give improved growth of different tropical crops, but also show the potential to increase resistance of the host to root pathogens and to reduce the severity of foliar disease. Most tropical perennial crops are propagated from seeds or cuttings in nurseries before they are transferred to the plantations. These crops are normally hosts for vesicular-arbuscular mycorrhizal fungi. An important characteristic of an inoculum of high quality is that it should be uncontaminated or contain only small quantities of plant pathogenic micro-organisms. Depending on the purpose for which the inoculum is produced, a low level of contamination can be ignored. The chapter further highlights control of inoculum infectivity.
