Overview of Company and Facility Locations

American Vanguard Corporation (AMVAC) and AMVAC Chemical Corporation have been issued a Stop Sale, Use or Removal Order (SSURO) for potential violations of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). EPA took enforcement action after EPA laboratory analysis of AMVAC's registered pesticide product, Technical Grade PCNB 95%, revealed the presence of highly toxic impurities EPA considers to be of toxicological significance.

The products involved include AMVAC's technical grade and manufacturing-use pentachloronitrobenzene (PCNB) products, as well as numerous registered end-use products derived from the technical grade and manufacturing-use PCNB products. In addition, there are several downstream registrants of PCNB products that use AMVAC's technical grade and manufacturing-use products to formulate their own pesticides. EPA has reason to believe these downstream products also contain impurities and intends to issue SSUROs to those businesses as well.

AMVAC Chemical Corporation, along with its subsidiaries, is a global partner of American Vanguard Corporation, a diversified specialty and agricultural products company that develops and markets crop protection, turf and ornamental products, and public health insecticides. AMVAC products include insecticides, fungicides, herbicides, soil fumigants, defoliants, molluscides, and growth regulators. AMVAC specializes in working with agricultural businesses and marketing crop protection products in the agricultural marketplace. AMVAC products are marketed in liquid, powder, and granular formulations.

In 2009, AMVAC reported net sales of $209,320,000. AMVAC parent company is located in Newport Beach, California; AMVAC Chemical Corporation is located in Los Angeles, California; and AMVAC branches are located in Salt Lake City, Utah and Marsing, Idaho.

Potential Violations

EPA has reason to believe AMVAC's PCNB products are in violation of FIFRA. Additionally, EPA believes AMVAC and AMVAC Chemical Corporation have distributed and sold, and intends to continue distributing and selling these pesticide products in violation of FIFRA.

  • Composition Differs - Any distribution or sale of any registered pesticide product for which the Confidential Statement of Formula (CSF) does not accurately reflect the composition of the product is a violation of FIFRA Section 12(a)(1)(C) , 7 U.S.C. § 136j(a)(1)(C). AMVAC's pesticide, Technical Grade PCNB 95% (EPA Reg. No. 5481-197) has been shown to contain impurities of toxicological significance and therefore its composition differs from the CSF under which it was registered.

Health and Environmental Effects

Primary uses are as fungicides with a wide variety of uses to control fungal diseases on vegetable crops (such as beans, cole crops (i.e., cabbage), potatoes, peanuts, flowering bulbs and garlic, as well as products for seed treatment and controlling soil-borne diseases in turf. Based on recent studies of AMVAC's technical grade pesticide, impurities of toxicological significance are present at significant levels in AMVAC products. During the past year, Australia and Canada have taken steps to prohibit the distribution and sale of AMVAC's PCNB products due to these impurities.
