PR#PriorityPesticide(MFG)Commodity (Crop Group)Project Status

Reduced Risk Status:
IPM Compatibility: Per Requester: Good Fit; reduces emergence of weeds and slows their growth, allowing for more timely weed control options later in the season. It may prevent weed pressure from building up to threshold levels. It may control weeds throughout the critical weed free period:02/24
Reasons for need: weeds; Only one other preemergence herbicide is registered in hemp (Sonalan / ethafluarlin). Additional, more effective options are needed:02/24
Requesting State(s): VA:Flessner, M* ;
PCR Use Pattern: Zidua SC herbicide applied once at 2.5 to 5.0 fl oz/a premergence or early postemergence to hemp. Original request indicated 0.5 day re-treat interval. IR-4 HQ suggests that this was probably misunderstood as re-entry interval and should actually be zero since only one application is requested.
