Research progress and prospects of microbial pesticide formulation for plant disease control

Formulation types of microbial pesticide for crop disease include dustable powder, wettable powder, granules, water dispersible granule, aqueous suspension concentrate and so on. In China, wettable powder is the main formulation of microbial pesticide for crop disease control. The research in other formulation types such as water dispersible granules, aqueous suspension concentrate and others need to be strengthened. The number of living organisms, processing conditions, storage conditions and field environmental factors may have important influence on the efficacy of microbial pesticide to control plant diseases. Evaluating these effects and studying the reasons and the inherent mechanism is of great importance for the development of microbial pesticide for plant disease control. In the light of performance of microbial pesticide for crop diseases, the present research reviewed the status, problems and development trend in the aspects of formulation types, performance or quality control and the effects of production, storage and field condition.
