Summary of Petition
The petitioner summary of the pesticide petition is printed below
as required by section 408(d)(3) of the FFDCA. The summary of the
petition was prepared by the petitioner and represents the view of the
petitioner. EPA is publishing the petition summary verbatim without
editing it in any way. The petition summary announces the availability
of a description of the analytical methods available to EPA for the
detection and measurement of the pesticide chemical residues or an
explanation of why no such method is needed.
EPA has received a pesticide petition (PP 1F6344) from Gustafson
LLC, 1400 Preston Road, Suite 400, Plano, TX 75093, proposing pursuant
to section 408(d) of the FFDCA, 21 U.S.C. 346a(d), to amend 40 CFR part
180 to establish an exemption from the requirement of a tolerance for
the microbial pesticide Bacillus pumilus GB34 when used as a seed
treatment in or on all raw agricultural commodities and on all food
commodities after harvest.
Pursuant to section 408(d)(2)(A)(i) of the FFDCA, as amended,
Gustafson LLC has submitted the following summary of information, data,
and arguments in support of their pesticide petition. This summary was
prepared by Gustafson LLC and EPA has not fully evaluated the merits of
the pesticide petition. The summary may have been edited by EPA if the
terminology used was unclear, the summary contained extraneous
material, or the summary unintentionally made the reader conclude that
the findings reflected EPA's position and not the position of the
A. Product Name and Proposed Use Practices
The active ingredient Bacillus pumilus GB34 is formulated into the
technical product, GB34 Technical Biological Fungicide and the end use
product GB34 Concentrate Biological Fungicide. GB34 concentrate
contains bacteria which colonize the developing root system of soybeans
suppressing disease organisms such as Rhizoctonia and Fusarium that
attack root systems. GB34 concentrate is used as a seed treatment
B. Product Identity/Chemistry
1. Identity of the pesticide and corresponding residues. Bacillus
pumilus GB34 is a naturally occurring isolate from the soil.
2. Magnitude of residue at the time of harvest and method used to
determine the residue. Two processing studies with soybeans were
conducted. The studies showed no uptake of Bacillus pumilus GB34 beyond
the seed hull. No residues were found in meal, oil, soymilk, or tofu.
3. A statement of why an analytical method for detecting and
measuring the levels of the pesticide residue are not needed. An
analytical method for enumeration of microorganisms is available but is
not required since the petitioner is requesting an exemption from the
requirement of a tolerance.
C. Mammalian Toxicological Profile
Bacillus pumilus GB34 was not found to be toxic or pathogenic from
acute intravenous administration of 1.1 x 107 cfu of
technical grade material. The oral LD50 of GB34 technical
was greater than 5,000 milligrams/kilograms (mg/kg) of body weight.
GB34 technical was classified non-irritating to the skin and mildly
irritating to the eye in primary skin irritation and eye irritation
studies. The oral LD50 of GB34 concentrate was greater than
5,000 mg/kg of body weight. GB34 concentrate was classified as non-
irritating to the skin and minimally irritating to the eye in primary
skin irritation and eye irritation studies. An avian oral pathogenicity
and toxicity study in northern Bobwhite showed no evidence of
pathogenicity during gross necropsy. The no observed adverse effect
level (NOAEL) was approximately 3.4 x 1011 cfu/kg/day for 5
D. Aggregate Exposure
1. Dietary exposure--i. Food. Bacillus pumilus GB34 does not
mammalian toxicity. Therefore, any dietary exposure would not be
harmful to humans. Also Bacillus pumilus GB34 is a naturally occurring,
ubiquitous microorganism indigenous to the United States.
ii. Drinking water. Bacillus pumilus is found in the soil and the
use rate of GB34 concentrate is 0.1 ounces per 100 pounds of seed,
equivalent to 1.7 grams per acre. Bacillus pumilus GB34 is unlikely to
leach from the treated seed and would not be distinguishable from other
naturally occurring Bacillus pumilus.
2. Non-dietary exposure. As a commercial seed treatment for
soybeans, the general population, including infants and children, will
have a very low possibility of exposure. Occupational exposure will be
limited to employees in commercial facilities handling the seed
treatment product. Commercial seed treating equipment minimizes
occupational exposure. Wearing protective equipment will also minimize
occupational exposure. Non-dietary exposure would not be expected to
pose a quantifiable risk.
E. Cumulative Exposure
The product strain belongs to the bacterial genus of Bacillus.
Bacillus pumilus GB34 may have a similar mode of action in mammals as
Bacillus subtilis that has been shown to be non-toxic and non-
pathogenic in mammalian species. A similar mode of action of Bacillus
pumilus GB34 and Bacillus subtilis would not be expected to result in
an increased adverse effect since both were shown to be non-toxic and
non-pathogenic in intravenous toxicity and pathogenicity studies.
F. Safety Determination
1. U.S. population. Based on the low treating rate of seed
treatment use, little evidence of toxicity or pathogenicity and limited
exposure potential, Gustafson LLC believes there is a reasonable
certainty of no harm to the U.S. population in general from aggregate
exposure to Bacillus pumilus GB34 residue from all anticipated dietary
and non-dietary exposures.
2. Infants and children. Based on the lack of toxicity and low
exposure there is a reasonable certainty that no harm to infants,
children or adults will result from aggregate exposure to Bacillus
G. Effects on the Immune and Endocrine Systems
Gustafson LLC has no information to suggest that Bacillus pumilus
GB34 will have any effect on the immune and endocrine systems.
H. Existing Tolerances
There are no existing tolerances for Bacillus pumilus GB34.
I. International Tolerances
Gustafson LLC is not aware of any international tolerances,
exemptions from tolerance or maximum residue levels for Bacillus
