Dr. Chin,
An rei of 5 days in coastal cole crops may be a little too much for most growers since in the spring and summer these crops move very quickly and the grower needs to get back into the field in a timely manner to perform certain cultural practices. Would the use of sprinklers in the field make our arid climate (central coastal California) a non-arid climate? Just something to think about.

Dear Colleagues:
EPA is proposing to increase the REIs from two days to five days in arid
areas (the REIs will remain 2 days in non-arid areas) for cauliflower and
broccoli (at the 0.5 lb ai/Acre rate; 3 applications, 7 days between
treatments.)
Please let me know if 5 days for REIs for bro! ccoli and cauliflower in
non-arid areas is unacceptable.
Also, we are still discussing the maximum numbers of applications on
celery at the 0.5 lb ai/Acre rate with 7 days between treatments. FYI. The
REI will be reduced to one day in non-arid areas and stay the same in Arid
areas at 2 days.
Please do not hesitate to contact me if you have any questions or comments.
Best regards,
