| Reduced Risk Status: |
THIS AI HAS BEEN CLASSIFIED AS RR FOR ONE OR MORE FOOD USES.
|
| IPM Compatibility: |
This is a new mode of action for use in strawberry nurseries for suppression of crown and root rot and red stele. Revus will not only bring a new MOA but will also allow more robust rotations for resistance management.
|
| Reasons for need: |
More Phytophthora epidemics have been occurring in nursery fields. Currently there are only 2 modes of action that can be used for Phytophthora management in nurseries. One of them (mefenoxam FRAC4) is prone to resistance development. More modes of action are needed to develop a rotation program; CA-is overly reliant on mefenoxam for Phytophtora prevention & mgmt. Nurseries have been advised by researchers that our use threatens to create resistance as the material with the same mode of action is used at the nursery and fruit growing level. Tool needed with a different MOA:05/25; FL-Having an additional mode of action for use in strawberry nurseries will help protect mefenoxam efficacy in fruit production fields, as resistance has already been shown to originate from infected transplants:05/25; CA-Disease control and resistance mgmt:05/25; SC-a few nurseries in the stat that would benefit from registering for this use:05/25; CA-We have only one curative chemistry for use when we have phytophthora infections being Ridomil which we use sparingly due to resistance build up. Add'l tolls will help minimize risk by allowing FRAC group rotations:05/25; CA: Please add application through drip tape chemigation or conventional tractor spray rigs at 50-100 gpa:06/25;

| PCR Use Pattern: |
Proposed use is for production of daughter plants in nursery fields; These field-produced daughter plants will then be harvested and used for plant stock for commercial fruit production fields. Use Revus; 8-16 fl. oz/A; Overhead chemigation (sprinkler), Max annual rate 32 fl. oz/A; RTI: 30 days; No PHI since it is intended to use on non-bearing plants
