Posted on Dec 28, 2018 in Main

Act 45 was passed by the 2018 Legislature and establishes new requirements regarding the use of pesticides in Hawaii. The following are new requirements that are effective on January 1, 2019.


Act 45 requires that all Certified Applicators of Restricted Use Pesticides (RUP) submit a report of the RUP that were applied each year.  Use Form P-45 to list all RUP products used and submit the form to HDOA’s Pesticides Branch by January 30th for the previous year.

The information on this form will be used to generate a report, for departmental use, that will provide the amount of RUP products used by County and includes the total quantities used, EPA Registration Number(s), commercial product names, and active ingredients for each RUP used.  The report will also include the amount of area in the county in which the RUP application occurred.
