Pyribencarb 是一种氨基甲酸苄酯型杀菌剂，对多种植物病原真菌具有活性。Pyribencarb 是一种有效的细胞色素 b (cytochrome b) 的 Qo 抑制剂。Pyribencarb 对灰霉病菌和核盘菌特别有效。

Pyribencarb is a benzylcarbamate-type fungicide, which is active against a wide range of plant pathogenic fungi. Pyribencarb is a potent Qo inhibitor of cytochrome b. Pyribencarb is especially active against Botrytis cinerea and Sclerotinia sclerotirum.

Pyribencarb potently inhibits succinate-cytochrome c reductase (SCR) activities of Botrytis cinerea (cucumber gray mold), Corynespora cassiicola (leaf spot) and decylubiquinol-cytochrome c reductase (UCR) activity of B. cinerea. Pyribencarb inhibits the UCR of B. cinerea in an uncompetitive manner, and the substrate-dependent inhibition constant is found from calculation to be 13 nM[1]. The target site of Pyribencarb is cytochrome b of complex III in the electron transport system of the respiratory chain. The inhibitory potency of pyribencarb on SCR activities of plants, rats and carp is relatively weak compared with that of strobilurin fungicides[1].
