### AQUATIC PESTICIDE USE IN NEWJERSEY– 2005

In 1983 the NJDEP Pesticide Control Program (PCP) implemented an Aquatic Pesticide Use Permit Program. The specificpurpose ofthisprogram was to identify and control whatpesticides arebeing applied to NewJersey’s waterbodies. Recently, the PCP was able to gather data from Records ofActual Treatment (RATS) and compute the total amount ofeach aquaticpesticide used during the aquaticpermit season, whichruns from April to October. Furthermore, this total usagehas alsobeenbroken down into Active Ingredientby County andbyWatershed Management Area. All aquatic applicators areresponsible for submitting their RATS forms to the department by November 15 ofeach treatment year. Theserecords are then entered into the PCP’s database, and checked for any errors or misapplications. Once corrected, these data are analyzed and thepounds ofactive ingredient used determined for each treatmentrecord. These data are then transposed to display the differentpermutations listed above. Table 1 lists the chemicals and their amounts inpounds ofactive ingredient (A.I.)used during the 2005 Aquatic Pesticide Permit season. The most widelyused trade names corresponding with these chemicals are also included. Table 2 lists the chemicals and their A.I. amounts appliedby county forthe 2005 season. Table 3 lists the chemicals and their A.I. amounts appliedbyWatershed Management Areas for the 2005 season.

This information willhelpus address the impacts, ifany, ofspecific aquaticpesticides to the environment in aparticular area, as well as tracktheuse ofthesepesticides. However, we mustkeep in mind that aquatic ecosystems are extremely dynamic and may change significantly from year to year and thus, may effect the trend ofsuchpesticide usage overtime. Another factor is the adoption ofIPM (Integrated PestManagement). One ofthe goals ofthe Pesticide Control Program ispesticide usereduction, and IPM is a tool that canbeused to achieve this. Although aquatic IPMpractices are currently few, many lake management associations have already incorporated some techniques into their managementprograms. The following datahasbeen gathered and charted forthere is a general interest in the trends ofaquaticpesticide use for the control ofaquatic weeds throughout the state of NewJersey. All information isbased onpermitted sites only.Table 1. Compoundsused during the 2005 Aquatic Pesticide Permit season and their amounts (pounds ofactive ingredient).
