Abstract： RNA fungicides use RNA interference technology to inhibit or kill crop pathogenic bacteria by suppressing the expression of important functional genes. These fungicides have strong targeting and environmentally friendly characteristics， which are beneficial for green and precise prevention and control of crop diseases. The mechanism of RNA interference， dsRNA synthesis technology， research and development of RNA fungicides and their application in disease prevention and control were summarized. And the existing problems of RNA fungicides were analyzed， prospect for their future development trends was presented.

Key words： RNA fungicides; RNA interference; crop diseases; research progress

作物病害的发生给农业生产造成严重的经济损失，目前对农作物病害的防控主要是采取化学农药防控，但化学农药过量使用导致病害抗药性增强、农药残留超标、生物多样性降低和环境污染等负面问题[1]，导致防治成本提高，还严重影响农产品品质和人体健康。（剩余10287字）
