The invention belongs to the technical field of pesticides and discloses a cyhalofop-butyl pyriminobac-methyl penoxsulam oil flowable concentrate.
Active components of the oil flowable concentrate are cyhalofop-butyl, pyriminobac-methyl and penoxsulam; the oil flowable concentrate comprises, by
mass, 5 to 30% of cyhalofop-butyl, 1 to 10% of pyriminobac-methyl, 1 to 10% of penoxsulam, 1 to 15% of an emulsifier, 1 to 10% of a
wetting dispersant, 0.1 to 5% of a suspension stabilizing agent, 0 to 5% of an antifreezing agent and 0.1 to 0.2% of a defoaming agent, with the balance being an oil base. The invention further discloses application of the oil flowable concentrate in prevention and killing of
Alternanthera philoxeroides, Sagittaria pygmaea and barnyard grass in a
paddy field. The oil flowable concentrate has a substantial synergistic effect, can substantially improve prevention and treatment effects on weeds, broadens a
weed control spectrum, delays resistance of weeds, decreases an application amount, reduces application cost and has excellent spreading permeability, anti-shifting performance and anti-rainwash performance and high safety to crops.
