Domestic microbes which had the antifungal, pesticide residue degradable, and heavy metal adsorbent activities were isolated individually. Mutants of their improved functions were induced by radiation. And finally microbial formulae of biocontroller were manufactured and respected to be industrialized promisingly. The effectiveness of the developed microbial formulae were confirmed in pepper, radish, and Chinese cabbage by field experiments for 5 kinds of fungal diseases. This technology is respected to be transferred to the agricultural companies. And a novel venture company could be established by the involved researchers using this technology. As a result, the productivity in environmentally-friendly farm could be improved gradually in the near future.
