Product Specifications

Mode of Entry: Contact and residual soil action

Time of Application: Pre-emergence

Mode of Action: Flumioxazin belongs to the PPO (Protoporphyrinogen Oxidase) inhibitor group of herbicides. It blocks an enzyme essential for chlorophyll formation in weeds. As a result, targeted weeds fail to establish and die during germination and early growth. The herbicide forms a protective layer on the soil surface, controlling weeds as they emerge.
