NJ Farmers Soil Fumigant Compliance Inspection Advisory

During the weeks of May 13-17 and June 3-7, the NJDEP Pesticide Control Compliance and Enforcement will be conducting inspections of NJ farmers who currently or previously reported using soil fumigants, primarily Vapam (metham sodium).

There are about 50 NJ farms reporting fumigant use. These farms will be the targets of the compliance assistance inspections. The inspections are being conducted by NJDEP as non-citation “compliance assistance” in response to changing regulations from US EPA for assuring safety of fumigant application workers by licensed applicator farmers.

Growers Guide to Protectant Fungicides (FRAC codes M1 – M9)

Protectant (contact) fungicides typically offer broad spectrum control for many different pathogens. Protectant fungicides belong to FRAC groups which have a low chance for fungicide resistance to develop. These include:

  • the inorganics (copper, FRAC code M1) and sulfur (FRAC code M2),
  • the dithiocarbamates (mancozeb, FRAC code M3) and chloronitriles (chlorothalonil, FRAC code M5)

Just a Bud or Another Bug?

Unfortunately, this one is another bug.

Pine Sawfly Larval Case

The pine sawfly is normally kept under control by natural predators so I rarely see them. This, however, was my second sighting in the last 4 months so I guess environmental conditions have not be optimal for predator survival.

Keep a lookout for these insects. The larvae are voracious eaters that completely devour the needles and can totally defoliate pine trees. The first site I visited had a block of about 25 trees more than 20 feet tall that were without needles.


If treatment is necessary, first generation control will need to occur from mid-May to mid-June. The second generation is active in the July to August time period. Cornell University Cooperative Extension of Suffolk County put together a good review of pine sawflies. It can be found at:
