| Reduced Risk Status: |
|
| IPM Compatibility: |
Per Requester: Good Fit; Useful for controlling weeds with known resistance to diuron, glyphosate and paraquat. Potential for chemical control of grape suckers. Low use rate herbicide as compared to glyphosate and glufosinate. Low risk of off-target movement due low vapor pressure. Limited number of PPO herbicide currently labeled for POST weed control in grape. Because of POST grass control, Epiryfenacil will provide an alternative to Group I herbicides
|
| Reasons for need: |
Annual grasses and broadleaf weeds, including bluegrass, horseweed, common lambsquarters, morningglory, Virginia pepperweed, common ragweed.Annual bluegrass (diuron and glyphosate resistant), horseweed (glyphosate and paraquat resistant), limited non-selective postemergence herbicides available for use in blueberry to replace paraquat, or complement the use of glufosinate; glufosinate and glyphosate may cause severe crop injury either dur to trunk splitting (glufosinate) or systemic activity trough sucker absorption (glyphosate):08/24;

| Requesting State(s): |
KY:Bessin, R ; NC:Mitchem, W ; NJ:Besancon, T* ; NY:Sosnoskie, L ; OH:Robinson, A ;
|
| PCR Use Pattern: |
Make 3 applications of Rapidicil at 5 fl oz/a plus adjuvant per year, 30 days apart, with the last application at least 14 days prior to harvest. Applications will be made along both sides and across the base of the crop. Valent supports a max of 2 applications with a 30 day retreatment interval during dormant and prior to bud break. Maximum annual use of 10 fl oz/A. Target use rate of 5 fl oz/A with a maximum per application use rate of 10 fl oz/A. Labeling will require tank mixture with another burndown herbicide for resistance management/product stewardship:08/24

Key Exports: Europe, Canada. Email from registrant indicated concern with systemic movement if suckers or other green tissue is exposed to spray. Early input from the registrant indicated only dormant uses in perennial crops:08/24/sb; Valent supports as Potential: E/CS Data Before Approval for Residue, with the Use Pattern noted:08/24/sb;
