Abstract
Potato late blight, caused by *Phytophthora infestans*, is a devastating disease. This study designed a self-assembled multicomponent nano-bioprotectant using dsRNA and a plant elicitor. Nanotechnology solved the dsRNA delivery bottleneck for *P. infestans*, extending RNAi protection. The nano-enabled dsRNA and elicitor synergistically boosted dsRNA stability, optimized intracellular delivery, and amplified plant defense. Field tests showed superior control efficacy compared to a commercial pesticide.
