Dual actions of chloroinconazide on pepper blight in <scp><i>Capsicum annuum</i></scp>: disruption of <scp><i>Phytophthora capsici</i></scp> mycelium and activation of <scp>CaCNGC9</scp>‐mediated <scp>SA</scp> signaling

CHI exhibited potent dual inhibitory effects on P. capsici by disrupting mycelial structure and activating the CaCNGC9-mediated SA signaling pathway. These dual mechanisms of action suggested that CHI could serve as a promising alternative chemical fungicide for the effective management of pepper blight, offering a new approach to control this devastating disease. Our findings highlighted the potential of CHI as a sustainable and efficient solution to combat the increasing resistance of P. capsici to conventional fungicides, ensuring better crop protection and yield. © 2024 Society of Chemical Industry.
