Copper Refined Actual Use Rates for Crops -- Hawaii
Ron,
Thank you for the call acknowledging the receipt of Hawaii's information.
Attached is the spreadsheet of Hawaii use data including information for papaya. Numbers which are larger than the previous version of the spreadsheet from the Task Force are indicated in red.
Also attached is some explanation for the papaya numbers. As you can see, a limitation of 5 applications per year is inadequate for papaya growers in Hawaii.
Regarding betel nut, this crop did not appear on any versions of the
Task Force spreadsheets. The numbers are based on a 24(c) registration
for Guam and a conversation with a pathologist on Guam.
Copper is not used every year on betel nut on Guam, but only when there
is an outbreak of the disease.
If you have any questions or concerns, please contact me.
Thank you,
Cathy
