1. A method for providing effective weed control of protoporphyrinogen oxidase (PPO) resistant weeds, comprising applying to such weeds, parts of it, its propagation material or its habitat with the compound of formula (I).1

OG Complex Work Unit Chemistry
wherein the PPO resistant weeds contain a ΔG210 mutation in the Protox enzyme conferring resistance to PPO-inhibiting herbicides;
wherein the application of the compound of formula (I).1 is during and/or after the emergence of the PPO resistant weeds, and
wherein the compound of formula (I).1 is applied at a rate in the range of from 5 g/ha to 2000 g/ha.
