**7. Bioformulation**

*Pseudomonas* spp. and *Trichoderma* spp. have many success stories as a part of bioformulation inducing disease resistance and plant growth promotional activities. Different organic and inorganic carrier materials may function for effective delivery of biocontrol agents. However, the concentrated formulation with potential biocontrol agents provided an extra advantage of smaller packaging with respect to storage and transportation, and low product cost as compared to other carrier

materials such as charcoal, vermiculite, sawdust and cow dung [92]. A talc-based formulation with *T*. *harzianum* was developed aiming at supply of concentrated conidial biomass of the biocontrol agent with high colony forming units (CFU) and long shelf life which significant increased the plant growth promotion [93]. The application of seed based bioformulation using *Pseudomonas fluorescens* not only reduced the disease incidence of *F. verticillioides* causing disease of maize but helped the plant to achieve the plant's growth [93].
