3(2H)-pyridazinone derivatives: a new scaffold for novel plant activators

“…Several plant activators, such as PBZ, 6 BTH, 7,8 TDL, 9 and ISOTIANIL 10 that molecularly mimic salicylic acid (SA), could induce the plant's systemic acquired resistance 4 and have been commercially applied in crop protection. 11–16 Owing to the great advantages of plant activators, it is necessary to develop more efficient and eco-friendly plant activators to protect plants.…”
