This paper explores the application of asynchronous intermittent control (AIC) in stochastic highly nonlinear delayd systems (SHNDSs) with regime-switching diffusion, and studies the$p$-th moment exponential stability of the controlled systems. For SHNDSs that no longer satisfy linear growth conditions but rather polynomial growth conditions, a new Lyapunov functional is constructed, which includes both$p$-th power and$q$-th power terms ($q >p \geq \rm {2}$). Additionally, this paper introduces AIC into SHNDSs due to the independent-response of each node, which leads to traditional Halanay inequalities are no longer applicable. To address this, we introduce an auxiliary timer to the new constructed Lyapunov functional. By taking the Dupire's functional derivatives, combined with the Dupire's functional Itô formula for regime-switching and graph theory methods, the negative-definiteness of$\mathbb {L}\mathcal {V}$is successfully ensured in both the working interval and the resting interval of the control cycle, effectively guaranteeing the stability of the systems. As a result, some criteria for the$p$-th moment exponential stability of SHNDSs under AIC are provided. Finally, the theoretical results are utilized in the analysis of the stochastic delayed van der Pol-Duffing oscillators with regime-switching, while the simulation results confirm the efficacy of these findings.
