| Reduced Risk Status: |
|
| IPM Compatibility: |
Per Requester: Very Good Fit; Fluridone would fit well in carrot IPM because it would add another preemergence herbicide option with activity on pigweed species and a different mode of action from many current carrot herbicides. It could be integrated with existing practices while helping manage resistant pigweed populations and reduce reliance on PSII inhibitors:06/26;
|
| Reasons for need: |
Pigweed species and other annual broadleaf weeds. Primary: redroot pigweed. Carrot growers have very limited herbicide options for pigweed control. Current programs rely mainly on pendimethalin and S-metolachlor preemergence, followed by linuron and other PSII inhibitors postemergence. However, resistance to PSII inhibitors is already widespread in pigweed species in the region. Resistance to Group 3 and Group 15 herbicides has not been confirmed locally yet, but cases have been reported in the US, so additional moa are needed to protect these tools. Current technologies used: Growers currently rely mainly on pendimethalin and S-metolachlor preemergence, followed by linuron and other PSII inhibitors postemergence. These options are limited, and pigweed control can be inadequate when resistance is present or when residual activity breaks down:06/26; FL:resistance mgmt:08/26; OR:new moa for resistance mgmt in carrot & carrot seed production. Resistance to PSII inhibitors is present in common groundsel and pigweeds:08/26;
