Double-Stranded RNA and Hypovirulence of Endothia Parasitica
The concept of biological control as a means of reducing the impact of disease or pest losses is an appealing one. The realization that the chemicals traditionally used to control pests can accumulate and have an adverse impact on the environment has created an interest in biological control as an alternative method of reducing the impact of pests. Biological control, however, has not generally proven to be successful, particularly in controlling microbial pests of plants. The difficulty in controlling microbial pests is that such control is dependent upon the use of other microorganisms that act as either antagonists or competitors of the pest species. For this approach to be successful, the competitor must be better adapted to the environment than the pest. This is difficult to achieve outside the laboratory where environmental conditions are so variable. The failure rate of biological control strategies has discouraged their widespread use (4).
