Reduced Risk Status:
IPM Compatibility: Per Requester: Very Good Fit: Glufosinate-ammonium use will offer a new mode of action for weed control in sugarcane and will aid in resistance management.
Reasons for need: Itchgrass [Rottboellia cochinchinensis (Lour.). Currently, the sugarcane industry is limited to paraquat for non-selective weed control utilizing post-directed/shielded/hooded applications. With concerns about the future of paraquat’s registration status, other herbicide options are needed. Glufosinate-ammonium may also provide benefits in controlling troublesome broadleaf weeds such as divine nightshade [Solanum nigrescens (Mart. & Gal.)], ragweed parthenium (Parthenium hysterophorus L.), and morningglory (Ipomoea spp.):06/24/sb
Requesting State(s): LA:Finger, A* ;
PCR Use Pattern: Make one application of Liberty/Rely per year to small weeds as 1) a directed spray, at 29 fl oz/a to row middles and across the lower (12" or less) canes or 2) shielded/hodded to row middles at 29 to 48 fl oz/a. Application shall be at least 75 days before cane harvest.
