      Plaintiff Ralph Rogerson, a licensed pest-control applicator in Kansas, challenges

a regulation of the Kansas Department of Agriculture, Kan. Admin. Regs. § 4-13-26
(2003), on the ground that it requires excessive pesticide treatment in preconstruction

applications.1 He filed suit for declaratory and injunctive relief against the Secretary of

the Department, claiming that the regulation (1) is preempted by the Federal Insecticide,

Fungicide, and Rodenticide Act (FIFRA), 7 U.S.C. §§ 136–136y, because it conflicts

with pesticide labels approved by the Environmental Protection Agency (EPA), and (2) is

preempted by the Sherman Antitrust Act, 15 U.S.C. § 1, because it limits consumer

choice and competition through retail price maintenance. The United States District

Court for the District of Kansas rejected both claims, and Plaintiff appeals. Exercising

jurisdiction under 28 U.S.C. § 1291, we affirm. The Kansas regulation is neither

expressly nor impliedly preempted by FIFRA. And Plaintiff has conceded the absence of

an essential element of his Sherman Act claim.

    I.      DISCUSSION

         The Kansas regulation requires both horizontal and vertical application of termite

pesticides in preconstruction areas. It states in full:

         In addition to the requirements of the label, each preconstruction
         application of pesticide for the control of termites shall consist of
         establishing both horizontal and vertical chemical barriers, as specified in
         this regulation.
         (a) Horizontal chemical barriers shall be established in areas intended to be
         covered, including the soil beneath slab floors and porches, footing trenches
         for monolithic slabs, and the soil beneath stairs.

         (b) Vertical chemical barriers shall be established in the soil around the
         base of foundations, plumbing fixtures, foundation walls, support piers, and

  Two other plaintiffs, Mary Ann Schoenhofer and Autumn L. Johnson, were dismissed
by the district court for lack of standing. They do not challenge that ruling on appeal.

       voids in masonry, and any other critical areas where structural components
       extend below grade.

Kan. Admin. Regs. § 4-13-26 (emphasis added). According to Plaintiff, however,

pesticide labels approved by the EPA under FIFRA do not require both horizontal and

vertical application, nor do they require application to as many areas as the regulation

requires. For example, as Plaintiff put it, an approved “label for I Maxx Pro [a pesticide

used by Plaintiff] . . . gives the applicator discretion to . . . conduct either vertical or

horizontal or both treatments,” and “states that only construction objects such as pipes

which penetrate the slab need treatment.” Aplt. Br. at 13–14.2 Also, he points out that

the label, in accordance with the command of 40 C.F.R. § 156.10(i)(2)(ii), states: “It is a

violation of Federal law to use this product in a manner inconsistent with its labeling.”

Pls.’ Resp. to Def.’s Mot. to Dismiss at Ex. 3, Aplt. App. at 71. He complains that the

Kansas regulation (1) endangers humans and the environment because it requires

  Regarding horizontal and vertical application, the label states: “The purpose of
chemical soil treatment for termite control is to establish a continuous chemical treated
zone (horizontal and/or vertical as needed) between the wood and other cellulose
material in the structure and the termite colonies in the soil.” Pls.’ Resp. to Def.’s Mot. to
Dismiss at Ex. 3, Aplt. App. at 72 (emphasis added). As for what areas to treat, the label
states:

       Apply an overall treatment to the entire surface of soil or other substrate to
       be covered by the slab including areas to be under carports, porches,
       basement floor, and entrance platforms. . . . In addition, apply 4 gallons of
       solution (see APPLICATION VOLUME) per 10 linear feet to provide a
       uniform treated zone in soil at critical areas such as along the inside of
       foundation walls, and around plumbing, bath traps, utility services, and
       other features that will penetrate the slab.

use of dangerous pesticides, and (2) stifles competition by requiring all

applicators to apply too much pesticide when some applicators could reduce their prices

by applying only necessary pesticide.

       Plaintiff raises two legal challenges to the regulation. Under FIFRA he contends

that the regulation is preempted by federally approved labels for pesticides because it

imposes stricter use requirements on pesticide applicators. And under the Sherman

Antitrust Act he contends that the regulation is preempted because it is a covert price

regulation that forces consumers to pay for unnecessary treatments and prohibits

applicators from competing against each other (since all are required to offer the same

unnecessary services).

       A. FIFRA Claims

       FIFRA is a “comprehensive regulatory statute” that regulates the sale, labeling,

and use of pesticides. Bates v. Dow Agrosciences LLC, 

, 437 (2005)

(internal quotation marks omitted). When a manufacturer wants to register a pesticide,

FIFRA requires that a proposed label and supporting information be submitted to the

EPA. See 

(citing 7 U.S.C. § 136a(c)(1)(C), (F)). The EPA will register the

pesticide if the manufacturer meets certain conditions, such as showing that the product is

effective and “will not cause unreasonable adverse effects on humans and the

environment.” 

136a(c)(5)(A), (C), (D); § 136(bb)). The States, within

limits, can also play a role. See 

“A State may regulate the sale or use of any

federally registered pesticide or device in the State, but only if and to the extent the
                                              4
regulation does not permit any sale or use prohibited by this subchapter.” 7 U.S.C.

§ 136v(a). Further, “A State [under certain circumstances] may provide registration for

additional uses of federally registered pesticides . . . .” 7 U.S.C. § 136v(c)(1). For

labeling, however, the statute requires national uniformity: “[A] State shall not impose or

continue in effect any requirements for labeling or packaging in addition to or different

from those required under this subchapter.” 7 U.S.C. § 136v(b); see Indian Brand

Farms, Inc. v. Novartis Crop Prot. Inc., 

, 214 (3d Cir. 2010) (“the states

have joint control with the federal government in regulating the sale and use of pesticides

with only the exception of the EPA’s exclusive supervision of labeling”). The reason for

requiring uniformity in labeling, but not in other subjects of regulation, is a pragmatic

one. State-by-state variation in how a pesticide is sold or used does not create any

significant inconvenience. But not so for labeling requirements. As the Supreme Court

expressed the point, “[I]magine 50 different labeling regimes prescribing the color, font

size, and wording of warnings—that would create significant inefficiencies for

manufacturers.” 

.

       Plaintiff appears to raise two preemption arguments. One is based on the

prohibition in § 136v(b) against “any requirements for labeling or packaging in addition

to or different from those required under [FIFRA].” Plaintiff contends that this

prohibition applies to the Kansas regulation because it is a labeling requirement, see Aplt.

Br. at 16 (the Kansas regulation “is in essence a labeling requirement, since it controls the

areas and structures to be treated in a manner which is inconsistent with the labels
                                              5
approved by the EPA”), and requires variations from the federal requirements. We

disagree. The prohibition in § 136v(b) does not apply here. The Supreme Court has

described the limits on “labeling or packaging” preemption:

       For a particular state rule to be pre-empted, it must satisfy two conditions.
       First, it must be a requirement “for labeling or packaging”; rules governing
       the design of a product, for example, are not pre-empted. Second, it must
       impose a labeling or packaging requirement that is “in addition to or
       different from those required under this subchapter.”

. Though Plaintiff devotes most of his attention to the second

condition, the first is not satisfied.

       FIFRA defines label as “the written, printed, or graphic matter on, or attached to,

the pesticide or device or any of its containers or wrappers.” 7 U.S.C. § 136(p). And it

defines labeling as “all labels and all other written, printed, or graphic matter--(A)

accompanying the pesticide or device at any time; or (B) to which reference is made on

the label or in literature accompanying the pesticide or device, except to [various

described] current official publications.” 

definitions—or common usage for that matter—the Kansas regulation

does not govern labeling. It governs use. It instructs termite-pesticide applicators how

and where to apply the pesticide. It does not say a word about what to put in any

“written, printed, or graphic matter” connected with a pesticide. The Supreme Court in

Bates provided examples of rules not affected by § 136v(b):

       Rules that require manufacturers to design reasonably safe products, to use
       due care in conducting appropriate testing of their products, to market
       products free of manufacturing defects, and to honor their express
                                              6
       warranties or other contractual commitments plainly do not qualify as
       requirements for “labeling or packaging.” None of these common-law rules
       requires that manufacturers label or package their products in any
       particular way.

(emphasis added). The Kansas regulation is even further removed

from the mandate of § 136v(b) because the regulation is addressed to those who apply

pesticides—not to the manufacturers who package or label them. Recall that the need for

national uniformity in labels and labeling is to avoid the “significant inefficiencies” if a

manufacturer had to produce a different label on its product for each State. 

There is no need for such stringent uniformity with respect to applicators, who can

readily adjust their operations for each State.

       Alternatively, Plaintiff appears to argue that, apart from the express preemption

language in § 136v(b), the state regulation is impliedly preempted. State law can be

impliedly preempted when it conflicts with federal law. See Arizona v. United States,

, 399 (2012). “This includes cases where compliance with both federal and

state regulations is a physical impossibility, and those instances where the challenged

state law stands as an obstacle to the accomplishment and execution of the full purposes

and objectives of Congress.” 

internal quotation marks omitted).

Preemption is not lightly inferred. See 

       Plaintiff’s argument is quite limited, contending only that the Kansas regulation is

preempted by FIFRA because it “requires more pesticide use than the [EPA-approved]

label,” Aplt. Br. at 18, and its “requirements . . . are . . . in fact inconsistent with the uses

                                                7
approved by the EPA,” 

Though somewhat unclear, he also may be arguing that

the regulation is preempted because it requires “additional uses” that have not been

approved by the EPA. 

All these arguments fail for a common reason: every

use required by the regulation is permitted by the label that Plaintiff relies on.

       Even assuming that an EPA-approved label could preempt state law,4 the conflict

alleged by Plaintiff does not exist. As mentioned earlier, Plaintiff argues that the Kansas


3
  In addition, Plaintiff may be arguing that the presence of the Kansas regulation has
somehow resulted in an independent violation of FIFRA by “causing misbranding of the
product.” Aplt. Br. at 19. But he has not sufficiently developed the argument to require
our review. See Murrell v. Shalala, 

, 1389 n.2 (10th Cir. 1994)
(undeveloped arguments insufficient to preserve appellate review). He utterly fails to tie
the regulation to FIFRA’s definition of misbranded in 7 U.S.C. § 136(q).
4
  It is not clear that EPA-approved labels can preempt state laws on their own; if
anything, Bates suggests the opposite. It identified only two sources of preemption:
FIFRA itself and any implementing regulations. See 

(“[Section
136v(b)] . . . pre-empts any statutory or common-law rule that would impose a labeling
requirement that diverges from those set out in FIFRA and its implementing
regulations.”). Indeed, the Court remarked: “At present, there appear to be relatively
few regulations that refine or elaborate upon FIFRA’s broadly phrased misbranding
standards. To the extent that EPA promulgates such regulations in the future, they will
necessarily affect the scope of pre-emption under § 136v(b).” 

n.28 (emphasis
added). It gave no indication that state rules could be preempted by federal labels alone.
Accordingly, some lower courts have stated that EPA approval of a product label likely
does not carry preemptive force. See Indian Brand 

(“[T]he
remand [in Bates] established that mere inconsistency between the duty imposed by state
law and the content of a manufacturer’s labeling approved by the EPA at registration did
not necessarily mean that the state law duty was preempted.”); see also Hernandez v.
Monsanto Co., No. CV 16-1988-DMG (EX), 

, at *6 (C.D. Cal. July
12, 2016) (“In noting that the ‘relevant EPA regulations that give content to FIFRA’s
misbranding standards’ have preemptive effect, the Bates Court appears to have been
referencing the EPA-promulgated regulations themselves, not the administrative
determinations made in approving a registration.” (quoting 

));
Hardeman v. Monsanto Co., No. 16-CV-00525VC, 

, at *2 (N.D. Cal.
                                              8
regulation conflicts with a label for I Maxx Pro, because it (1) limits the discretion of the

applicator in applying vertical and horizontal treatments and (2) requires the treatment of

additional surfaces. But the label does not forbid both vertical and horizontal treatments.

Rather, as Plaintiff himself describes the label, it “gives the applicator discretion to . . .

conduct either vertical or horizontal or both treatments.” 

And although the

label directs the applicator to treat “construction objects such as pipes which penetrate the

slab,” 

it does not forbid application to other objects. Thus, even though the

regulation and label are not congruent, the applicator can comply with both.5 We

therefore reject Plaintiff’s claim of preemption by FIFRA.6




Apr. 8, 2016) (“Of course, if the EPA’s approval of Roundup’s label had the force of law,
it would preempt conflicting state-law enforcement of FIFRA. . . . But there’s no
indication that the EPA’s approval of Roundup’s label had the force of law.” (citation
omitted)).
5
  We also note that the statutory provisions governing pesticide use permit state
departures from the applicable federal regulations. Both § 136v(a) and § 136v(c)(1)
expressly allow States to authorize, under certain circumstances, uses that deviate from
those approved by the EPA. See 

(“Most significantly, States may
ban or restrict the uses of pesticides that EPA has approved, § 136v(a); they may also
register, subject to certain restrictions, pesticides for uses beyond those approved by
EPA, § 136v(c).”).
6
  In addition, the Maxx Pro label deferred to local law. One section of the label begins:
“Treatment standards for subterranean termite control may vary due to regulations,
treatment procedures, soil types, construction practices and other factors.” Pls.’ Resp. to
Def.’s Mot. to Dismiss at Ex. 3, Aplt. App. at 72 (emphasis added). And the label further
directs the applicator to “[f]ollow all federal, state, and local regulations and treatment
standards for protection of a structure from termites.” 

Sherman Act Claim

       The Sherman Act provides in relevant part: “Every contract, combination in the

form of trust or otherwise, or conspiracy, in restraint of trade or commerce among the

several States, or with foreign nations, is declared to be illegal.” 15 U.S.C. § 1. The Act

has not been construed literally. As the Supreme Court has explained: “[A] judicial gloss

on this statutory language has established the ‘rule of reason’ as the prevailing standard

of analysis. Under this rule, the fact-finder weighs all of the circumstances of the case in

deciding whether a restrictive practice should be prohibited as imposing an unreasonable

restraint on competition.” Cont’l T.V., Inc. v. GTE Sylvania Inc., 

, 49–50

(1977) (citation omitted). A rule-of-reason analysis is unnecessary, however, for limited

categories of “per se” violations of the Act. These “are certain agreements or practices

which because of their pernicious effect on competition and lack of any redeeming virtue

are conclusively presumed to be unreasonable and therefore illegal without elaborate

inquiry as to the precise harm they have caused or the business excuse for their use.” 

(internal quotation marks omitted).

       Although the Sherman Act contains no express preemption language, the Supreme

Court has held that a state law is preempted if, and only if, it is the type of restriction on

economic freedom that always violates the Act:

       [A] state statute should be struck down on pre-emption grounds only if it
       mandates or authorizes conduct that necessarily constitutes a violation of
       the antitrust laws in all cases, or if it places irresistible pressure on a private
       party to violate the antitrust laws in order to comply with the statute.

Fisher v. City of Berkeley, 

, 265 (1986) (internal quotation marks omitted).

That is, “[s]uch condemnation will follow under § 1 of the Sherman Act when the

conduct contemplated by the statute is in all cases a per se violation.” Rice v. Norman

Williams Co., 

, 661 (1982). This standard reflects ordinary conflict-

preemption principles. See 

(“As in the typical pre-emption case, the inquiry is

whether there exists an irreconcilable conflict between the federal and state regulatory

schemes.”). And it “[r]ecogniz[es] that the function of government may often be to

tamper with free markets.” 

.

       Our analysis of Plaintiff’s claim can be brief. He acknowledges the per se

requirement for preemption. And he concedes that in light of recent Supreme Court

authority, “even if the effect of the proposed regulation is to reduce consumer choice and

maintain retail prices, such conduct is no longer a per se violation.” Aplt. Br. at 23–24.

There is nothing left for us to decide. Plaintiff raises a rule-of-reason challenge to the

regulation; but, to repeat, analysis of that challenge requires “weigh[ing] all of the

circumstances of the case,” Continental 

, and that is a process not

available in a preemption challenge to state law, see 

.7 We affirm

the district court’s dismissal of Plaintiff’s claim under the Sherman Act.



7
  Plaintiff may be making two final arguments under state law. He asserts that Kansas
law does not grant the Kansas Department of Agriculture a license to engage in economic
regulation. He also asserts that the Department did not prepare, as required by Kansas
statutory law, either an economic or an environmental impact study before promulgating
the regulation at issue in this case. We do not consider these arguments because he does
