QoI

Q_o inhibitors (Q_oI),^[1] or quinone outside inhibitors, are a group of fungicides used in agriculture. Some of these fungicides are among the most popular in the world.^[2] Q_oI are chemical compounds which act at the quinol outer binding site of the cytochrome bc₁ complex.

Most Q_oI common names end in -strobin and so are often called strobs.^[3] Q_oI's are the resulting fusion of three fungicides families, the well-known family of strobilurins and two new families, represented by fenamidone and famoxadone. Some strobilurins are azoxystrobin, kresoxim-methyl, picoxystrobin, pyraclostrobin, and trifloxystrobin.
