Grouping #14, Protoporphyrinogen oxidase (PPO) enzyme inhibitor, Inhibits protoporphyrinogen oxidase enzyme important in chlorophyll synthesis, Absorbed through the leaves does not move in the plant, Causes formation of a light-absorbing chlorophyll precursor outside of the chloroplast, This compound absorbs energy from sunlight, but cannot pass through the Z-scheme, Energy is passed on to oxygen, creating radical oxygen and cell membrane disruption, Not used as a plant growth regulator in Florida aquatic plant control applications, No tolerance or resistance issues reported in Florida, Resistance has been reported for PPO inhibitors in terrestrial applications, Rotate or combine with other active ingredient where appropriate, Important to know water depth to calculate appropriate concentration for submersed applications, Important to have accurate bathymetry to calculate appropriate concentration for submersed applications, Can be used in slow moving, quiescent waters, Relatively fast-acting contact type herbicide, Controlling large area may reduce dissolved oxygen level, Wait 10-14 days if treating as much as half of the waterbody, Use buffer if tank mix water exceeds pH 7, Apply submersed applications early in morning when pH is generally at lower values, Higher light intensity usually equates to more robust growth of submersed target plants, Sand/Clay no issues related to this tool, Does not adsorb to suspended material in water body or in tank mix water, Cabomba usually present in lower pH waters, Combination of flumioxazin at 100 ppb + diquat at 370 ppb, 50 ppb for submersed application to control water lettuce, Need an area >15 ac to compensate for dissipation, Increasing use for selective water lettuce control, ~50 ppb for submersed applications and 2-8 oz / ac foliar application, 4 oz / ac + 4 oz / ac penoxsulam for water lettuce / water hyacinth mix, 4 oz flumioxazin + 96-120 oz glyphosate / ac, Adding flumioxazin accelerates knockdown unclear if it increases efficacy, Need actively growing plants for herbicide uptake, Mature plants are more difficult to control due to higher carbohydrate reserve, Good alternative to diquat for controlling water lettuce mixed with bulrush, Does not cause bulrush stem spotting or browning associated with diquat applications, Foliar applications when wind speed < 10 mph to reduce damage from drift, Apply in early fall (Oct/Nov) or late winter (Feb/Mar) for best hydrilla control, Water lilies in application zone may be impacted, Especially when applied with diquat for hydrilla control, Regrowth from seed or new plants flushed into control zone, Regrowth is rapid when applied to mature or slowly growing hydrilla, Must kill root crowns to slow regrowth from tubers, Needs 4-8 hours of contact for good herbicidal activity, Need actively growing target plants for herbicide uptake, Higher light intensity usually equates to stronger growth and therefore better control of young submersed plants (hydrilla / cabomba), Similar chemistry available in carfentrazone, Not as much operational monitoring or use of carfentrazone, Area of submersed plant control (hydrilla, cabomba, limnophila, hygrophila) is generally confined to the area to which flumioxazin is directly applied, Low-dose submersed applications with expectations of dispersal to control water lettuce, Hydrilla efficacy improves when applying to young actively growing plants, Better efficacy during cooler weather October/November February/March, Longer control duration when root crowns killed, Needs 1-2 hours of foliar contact for control activity, Symptoms in 3-5 days control in 7-14 days, Needs 4-6 hours for good control activity, Symptoms in 7-14 days control in 14-28 days, Foliar applications by backpack, airboat for small-scale applications to water lettuce, Shallow hose for submersed application to control water lettuce, Apply with deep water trailing hoses for larger scale submersed plant control.
