WEEDS. Annual grassweeds, Broadleaf weeds, Weeds are a persistent problem for carrot production as carrots are poor competitors. Herbicides are essential for carrot production as high-density planting limits the use of mechanical options. Therefore, carrot growers have long relied on herbicides like metam, trifluralin, and linuron. New regulatory restrictions along with loss of crop tolerances and costly environmental monitoring studies may lead to the loss of some good herbicides:08/23; NY/Carrots are in critical need of novel weed control options, particularly with the evolution of linuron resistance in pigweed species:09/23

| E/CS Research Comments: |
no early season phytotoxicity evaluation data collected in 2023 trial; vigor after the second application looks acceptable, but significant crop phytotoxicity was observed from the late application of both rates; original supporting data did not include sequential applications of treatments, though sequential applications are desired.

Data under XH498 (rec'd 2/2014) is variable and was converted with this new request. Original supporting data did not include sequential applications of treatments, though sequential applications are desired, and a more complete report has been requested. Requester may also desire a chemigation option for preemergence application.08/23/rbb/sb; Category changed per MFG to Potential, MFG Requires E/CS Data Before Residue Study, 09/23 JPB;
