# AQUATIC PESTICIDE USE IN NEW JERSEY – 2006

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

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 tot al

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 t o 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 r ecord.

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.) use d

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 Managem ent

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

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 pesticide s.

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

change significantly from year to year and thus, may affect the trend o f 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 associ ations

have already incorporated some IPM techniques into their management programs.

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

trends of aquatic pesticide use for the control of aquatic weeds throughout the sta te of

New Jersey. All information is based on permitted sites only.Table 1. Compounds used during the 2006 Aquatic PesticidePermit season and their amounts (pounds of active ingredient).
