The Environmental Protection Agency has issued an order to HPI Products of St. Joseph, Missouri directing the company to immediately halt the sale or distribution of its supplies of Warthog 2 EC following reports that a tainted batch of the herbicide distributed by the company damaged 8,000 acres of soybeans near Beattie, Kan. Similar Stop Sale, Use or Removal Orders have been issued by EPA to the pesticide's registrant, J. Oliver Products of Hernando, Miss.; and to Pony Express Warehouse, in St. Joseph, Mo., which received distribution of the product from HPI Products.
The Missouri Department of Agriculture investigated and found that samples of Warthog 2 EC taken from stocks at HPI Products appeared to be tainted with another herbicide, Dicamba. The National Pesticide Information Center says Warthog 2 EC is commonly used to control annual and perennial grasses among a wide range of field crops, including soybeans. Dicamba is used to control broadleaf weeds in a variety of settings, and can be harmful to soybeans and other legumes.
