For disease management, Trichoderma spp was usually applied as an important role among biocontrol agents of plant diseases. So far, the biopesticides may mainly include biofungicides, bioinsectcides, and bioherbcides. Generally, the basic requirements of a successful system of biological control of plant pests are (a) an effective biocontrol agent, (b) production and formulation methods that give rise to high yields of biomass consisting of appropriate efficacious propagules of high viability and stability, and (c) delivery systems that provide a conducive milieu and minimize growth of competitive microflora. In addition, the processes of the biopesticides for commercially available still need to complete the field tests, and to pass toxicity tests, and registration by Environmental Protection Agency and Council of Agriculture of Taiwan. |
