As the second most important fungal pathogen, Botrytis cinerea (B. cinerea) poses a serious threat to crop yields and agricultural safety. Pyraclostrobin (PYR), broad-spectrum QoI fungicide, has been widely utilized since its launch in 2003. However, inhibitory effects of both PYR technical formulations on B. are not outstanding. Even at concentration 50 μg/mL, inhibition rates by remain below 85%. In this work, we prepared an acid-responsive Pickering emulsion encapsulating (PYR@BTIB-PE), which completely inhibited low concentrations (25 μg/mL) for first time. The PYR@BTIB-PE achieved fragmentation release within 4 min pH 5, was consistent with around cinerea. can rapidly when infected increased cinerea, thereby enhancing efficacy PYR. addition, released organic solvent from enhanced passing property membrane, facilitating more enter body improvement membrane rapid response worked together achieve complete Furthermore, flexible amphiphilic structures interaction leaf surface, suppressed droplet splashing, promoted spreading, reducing pesticide loss improving utilization rate pesticide. This study presents efficient strategy inhibiting is also expected be extended other antifungal preparations.
