ACTION: Plant related quarantine; domestic:

DOCUMENT ACTION: Proposed rule.

SUBJECT CATEGORY: Imported Fire Ant; Approved Treatments

DATES: We will consider all comments that we receive on or before May 20, 2003.

DOCUMENT SUMMARY: We are proposing to amend the imported fire ant regulations by adding the insecticide methoprene (Extinguish[reg]) to the list of chemicals that are authorized for the treatment of regulated articles. This product is registered by the U.S. Environmental Protection Agency for use against the imported fire ant and has been found efficacious based on testing by the Gulfport Plant Methods Center. This action would make methoprene available for the treatment of containerized plants and fieldgrown woody ornamentals in the quarantined areas.

SUMMARY: Fire ant, imported; methoprene, authorized treatment,

SUPPLEMENTAL INFORMATION

The imported fire ant, Solenopsis invicta Buren and Solenopsis richteri Forel, is an aggressive, stinging insect that, in large numbers, can seriously injure or even kill livestock, pets, and humans. The imported fire ant feeds on crops and builds large, hard mounds that damage farm and field machinery. Imported fire ants are notorious hitchhikers and are readily transported long distances when articles such as soil and nursery stock are shipped outside the infested area.

The Animal and Plant Health Inspection Service (APHIS) works to prevent further imported fire ant spread by enforcing a Federal quarantine and cooperating with imported fire antinfested States to mitigate the risks associated with the movement of regulated articles such as nursery stock and used soilmoving equipment. Also, APHIS evaluates the efficacy of regulatory treatments for preventing the artificial spread of imported fire ant and revises its regulations and procedures as necessary. APHIS works with States, industry, and other Federal agencies to develop and test promising new insecticides and biological control agents.

The regulations in ``SubpartImported Fire Ant'' (7 CFR 301.81 through 301.8110, referred to below as the regulations) quarantine infested States or infested areas within States and impose restrictions on the interstate movement of certain regulated articles from those quarantined States or areas for the purpose of preventing the artificial spread of the imported fire ant.

Sections 301.814 and 301.815 of the regulations provide, among other things, that regulated articles requiring treatment prior to interstate movement must be treated in accordance with the methods and procedures prescribed in the appendix to the subpart, which sets forth the treatment provisions of the ``Imported Fire Ant Program Manual.''

Tests conducted by APHIS's Gulfport Plant Methods Center in Mississippi have demonstrated that the insecticide methoprene (Extinguish[reg]) is efficacious at variable dosage rates in treating plants in containers and at 1.01.5 lb. (0.450.68 kg) bait/acre for treatment of fieldgrown woody ornamentals. On May 27, 1998, methoprene was registered by the U.S. Environmental Protection Agency (EPA) for use against imported fire ant in containerized plants and fieldgrown woody ornamentals.

Therefore, we are proposing to amend the appendix to the regulations to add the insecticide methoprene (Extinguish[reg]) as a treatment option for certain regulated articles requiring treatment against the imported fire ant. Specifically, we would amend the appendix to the regulations by adding methoprene (Extinguish[reg]) to:

1. The list of authorized chemicals;

2. The list of approved treatments for all nurseries within the quarantined area, to treat all exposed soil surfaces where plants are grown, potted, stored, handled, unloaded, or sold; and

3. The list of fire ant baits that may be used in combination with chlorpyrifos to treat fieldgrown woody ornamentals.

Miscellaneous

In addition to the proposed amendments described previously, we would also make one nonsubstantive change to the appendix to the regulations. Specifically, we would add a reference to the insecticide pyriproxyfen (Distance[reg]) to the second sentence of the paragraph titled Special Information in section III.C.5 of the appendix. When pyriproxyfen was added to the appendix as an approved treatment (see 64 FR 5796957971, published October 28, 1999), references to that product should have been added to all three sentences in the Special [[Page 13860]]
Information paragraph, but such a reference appears only in the first and third sentences of the paragraph. We would correct that omission. Executive Order 12866 and Regulatory Flexibility Act

This proposed rule has been reviewed under Executive Order 12866. For this action, the Office of Management and Budget has waived its review under Executive Order 12866.

This proposed rule would amend the appendix to the imported fire ant regulations to allow the use of the insecticide methoprene (Extinguish[reg]) against the imported fire ant. Methoprene is registered by the EPA for use against the imported fire ant in containerized plants and fieldgrown woody ornamentals and has been found to be efficacious against imported fire ant based on testing by the Gulfport Plant Methods Center in Mississippi.

Determining the cost to treat for imported fire ant in nursery operations is complicated because of the large number of insecticide products, varying soil conditions, and various types of nursery crops. For example, in two surveys conducted by Hall and Holloway (1994 and 1995) of 37 nursery crop growers in Texas, which represented more than half of all nursery crops produced in that State, chemical cost per treatment per acre for imported fire ant control averaged $12.10, with treatment costs representing up to 4 percent of their production cost. Almost half (47 percent) of those growers reported treating for imported fire ant and most of them reported using more than one pesticide in their operations (range=1 to 3; average=1.5) making the average cost per acre for insecticides to control imported fire ants $18.15 (i.e., 1.5 x $12.10).

Methoprene (Extinguish[reg]) would be the latest insecticide to be added to the regulations for the treatment of imported fire ant. The currently approved treatmentsFipronil (Chipco[reg]), Pyriproxyfen (Distance[reg]), Fenoxycarb (AWARD[reg]), Hydramethylnon (AMDRO[reg]), and Bifenthrin (Talstar[reg])cost approximately the same in the bulk market, $5 to $12 per pound, with each pound treating 17 colonies (i.e., mounds) of imported fire ant. However, any insecticide's retail price depends on the price charged by its local distributor and may vary from State to State. Although the insecticides generally do not differ greatly in price, at least some consumers can be expected to benefit from inclusion of methoprene as an alternative treatment. Impact on Small Entities

Businesses such as nurseries that work with regulated articles are the entities most likely to be affected by this proposed rule. This proposed rule would result in a wider selection of treatment options for imported fire ant. The economic effect on affected entities would either be positive, since a wider selection of insecticides will provide greater choice, or would have no effect, if they choose not to use methoprene.

The Regulatory Flexibility Act requires that agencies consider the economic effects of their rules on small businesses. Based on data from the 1997 Census of Agriculture, there were 14,762 nurseries and greenhouses in the 13 States that have been affected by imported fire ant plus Puerto Rico, of which 82 to 99 percent were small entities, according to the Small Business Administration criterion of annual sales of $750,000 or less.

It is expected that the economic effect of this proposed rule on these businesses would either be positive (a wider selection of insecticides will provide greater choice) or neutral (if they choose not to use methoprene). The majority (82 to 99 percent) of firms that may potentially be affected by this proposed rule are small entities.

Under these circumstances, the Administrator of the Animal and Plant Health Inspection Service has determined that this action would not have a significant economic impact on a substantial number of small entities.
