AQUATIC PESTICIDE USE IN NEW JERSEY – 2006

In 1983 the NJDEP Pesticide Control Program (PCP) implemented an Aquatic Pesticide 

Use Permit Program. The specific purpose of this program was to identify and control

what pesticides are being applied to New Jersey’s waterbodies. Recently, the PCP was 

able to gather data from Records of Actual Treatment (RATS) and compute the total 

amount of each aquatic pesticide used during the aquatic permit season, which runs from

April to October. Furthermore, this total usage has also been broken down into Active 

Ingredient by County and by Watershed Management Area. 

All aquatic applicators are responsible for submitting their RATS forms to the department 

by November 15 of each treatment year. These records are then entered into the PCP’s 

database, and checked for any errors or misapplications. Once corrected, these data are 

analyzed and the pounds of active ingredient used determined for each treatment record. 

These data are then transposed to display the different permutations listed above.

Table 1 lists the chemicals and their amounts in pounds of active ingredient (A.I.) used 

during the 2006 Aquatic Pesticide Permit season. The most widely used trade names 

corresponding with these chemicals are also included. 

Table 2 lists the chemicals and their A.I. amounts applied by county for the 2006 season.

Table 3 lists the chemicals and their A.I. amounts applied by Watershed Management 

Areas for the 2006 season. For more information on Watershed Management areas, 

please visit http://www.nj.gov/dep/watershedmgt, or contact the NJDEP Division of Watershed 

Management.

This information will help us address the impacts, if any, of specific aquatic pesticides to 

the environment in a particular area, as well as track the use of these pesticides. 

However, we must keep in mind that aquatic ecosystems are extremely dynamic and may 

change significantly from year to year and thus, may affect the trend of such pesticide 

usage over time. Another factor is the adoption of IPM (Integrated Pest Management). 

One of the goals of the Pesticide Control Program is pesticide use reduction, and IPM is a 

tool that can be used to achieve this. Over the past few years an increase in these

activities has been seen throughout New Jersey, as many lake management associations 

have already incorporated some IPM techniques into their management programs. 

The following data has been gathered and charted for there is a general interest in the 

trends of aquatic pesticide use for the control of aquatic weeds throughout the state of 

New Jersey. All information is based on permitted sites only.
