Micro Flo Company
PP 7F4801
EPA has received a pesticide petition (PP 7F4801) from Micro Flo
Company, P.O. Box 5948, Lakeland FL 33807, c/o SRA International, Inc.,
1850 M St., N.W., Washington DC 20036 proposing pursuant to section
408(d) of the Federal Food, Drug and Cosmetic Act, 21 U.S.C. 346a(d),
to amend 40 CFR part 180 by establishing an exemption from the
requirement for a tolerance for residues of plant regulator Bacillus
cereus BP01 when used in accordance with good agricultural practice as
an active ingredient in pesticide formulations applied to growing
crops.
Pursuant to section 408(d)(2)(A)(i) of the FFDCA, as amended, Micro
Flo has submitted the following summary of information, data, and
arguments in support of its pesticide petition. This summary was
prepared by Micro Flo and EPA has not fully evaluated the merits of the
petition. The summary may have been edited by EPA if the terminology
used was unclear, the summary contained extraneous material, or the
summary was not clear that it reflected the conclusions of the
petitioner and not necessarily EPA.
A. Proposed Use Practices
Micro Flo Company's Bacillus cereus BPO1 is a foliar-applied plant
regulator. When combined with the plant growth regulator, mepiquat
chloride, for use on cotton, it allows the grower to manage the cotton
plant for short-season production leading to reduced risk of yield and
quality loss due to delayed and prolonged harvest. Benefits derived
from BPO1 in conjunction with mepiquat chloride include increased early
boll retention and/or larger bolls, reduced plant height which provides
a more open canopy, less boll rot, improved defoliation, less trash and
lower ginning costs, better harvest efficiency and a darker leaf color.
Micro Flo is currently exploring potential uses of BPO1 on other major
row crops.
BPO1 is applied from early season when the cotton is actively
growing and not under stress, through late season on fields that cut
out and then regrow or on fields where the cotton does not completely
cut out. Application rates,
[[Page 34278]]
depending on the cotton variety and its vigor, vary from 0.03 - 0.38
grams BPO1/A.
The maximum application level for BPO1 on cotton is 0.75 gram/acre/
year, with an average of 0.2 g/acre/year. For row crops (e.g., corn,
soybeans), the maximum application will be less than 2 g/acre/
application and less than 20 g/acre/year. This tolerance exemption
petition is for use of Bacillus cereus BPO1 up to 20 g/acre/year. There
is a 30-day pre-harvest interval (PHI). Livestock should not be fed or
permitted to graze on BPO1-treated cotton forage.
B. Product Identity/Chemistry
1. Identity of the pesticide and corresponding residues. The ATCC
classification of Micro Flo's Bacillus cereus BPO1 is 55675. Only
residues of BPO1 would be present, and these residues are
indistinguishable from naturally-occurring Bacillus cereus without
using specific genetic testing procedures for differentiating them.
2. Magnitude of the residue anticipated at the time of harvest and
the method used to determine the residue. No magnitude of residue (MOR)
studies have been conducted on BPO1 as total application rates are
exceedingly low (Cotton: average, 0.2 g BPO1/acre/year; maximum, 0.75
g/acre/year; Other major row crops [e.g., soybeans, corn]: <20 g="" bpo1/="" acre/year)="" and="" it="" is="" toxicologically="" innocuous.="" the="" pre-harvest="" interval="" (phi)="" is="" currently="" 30="" days.="" bacillus="" cereus="" is="" indigenous="" and="" widespread="" throughout="" the="" united="" states="" and="" the="" rest="" of="" the="" world.="" 3.="" statement="" regarding="" the="" lack="" of="" need="" for="" an="" analytical="" method="" for="" detecting="" and="" measuring="" the="" levels="" of="" the="" pesticide="" residue.="" as="" indicated="" above,="" the="" naturally-occurring="" population="" of="" b.="" cereus="" may="" make="" it="" impossible="" to="" distinguish="" between="" natural="" and="" introduced="" microbial="" populations="" without="" utilizing="" genetic="" differentiation="" techniques="" and="" therefore="" to="" establish="" and="" enforce="" tolerances="" for="" bpo1.="" in="" addition,="" the="" phi="" is="" currently="" 30="" days.="" c.="" mammalian="" toxicity="" profile="" acute="" mammalian="" toxicity="" studies="" via="" oral,="" dermal,="" inhalation,="" eye,="" intratracheal="" and="" intravenous="" routes="" were="" conducted="" with="" bacillus="" cereus="" bpo1.="" no="" pathogenicity="" was="" observed.="" bpo1="" was="" also="" tested="" for="" enterotoxin="" production;="" none="" was="" detected.="" in="" a="" blood="" agar="" hemolysis="" assay="" conducted="" with="" bpo1,="" weak="" alpha="" hemolysis="" was="" observed.="" based="" on="" the="" results="" of="" the="" above="" studies,="" subchronic,="" reproductive,="" teratology,="" chronic="" and="" mutagenicity="" studies="" were="" not="" deemed="" necessary.="" d.="" aggregate="" exposure="" 1.="" dietary="" exposure--a.="" food.="" bacillus="" cereus="" bpo1="" is="" currently="" pending="" registration="" for="" use="" on="" cotton="" at="" rates="" up="" 0.75="" g/a/year.="" micro="" flo="" co.="" will,="" however,="" be="" evaluating="" bpo1="" for="" future="" registration="" for="" use="" on="" other="" row="" crops="" (e.g.,="" soybeans,="" corn)="" at="" rates="" less="" than="" 20="" g/="" a/year.="" considering="" the="" extremely="" low="" application="" rates,="" ubiquitous="" nature="" and="" natural="" occurrence="" of="" bacillus="" cereus,="" the="" potential="" dietary="" exposure="" to="" bpo1="" is="" minuscule.="" b.="" drinking="" water.="" bacillus="" cereus="" bpo1="" is="" prohibited="" on="" the="" label="" from="" direct="" application="" to="" water,="" although="" possible="" spray="" drift="" may="" contact="" drinking="" water.="" again,="" considering="" the="" extremely="" low="" application="" rates,="" non-toxic="" mode="" of="" action,="" ubiquitous="" nature="" and="" natural="" occurrence="" of="" bacillus="" cereus,="" the="" potential="" drinking="" water="" exposure="" to="" bpo1="" is="" minuscule.="" 2.="" non-dietary="" exposure.="" there="" is="" no="" anticipated="" non-dietary="" exposure="" to="" bacillus="" cereus="" bpo1.="" contact="" with="" naturally-occurring="" populations="" of="" b.="" cereus="" is="" common="" throughout="" the="" world.="" residue="" exposure="" through="" contact="" with="" cotton="" seeds/oil="" and="" clothing="" produced="" from="" bpo1-treated="" cotton="" has="" been="" theoretically="" considered;="" residues="" are="" unlikely="" to="" be="" present="" after="" the="" delinting/cleaning="" process.="" e.="" cumulative="" effects="" although="" there="" are="" other="" currently="" registered="" bacillus="" products,="" some="" of="" which="" hold="" tolerance="" exemptions,="" their="" modes="" of="" action="" are="" unlike="" bpo1.="" specifically,="" the="" other="" products="" typically="" produce="" enterotoxin="" which,="" when="" the="" bacteria="" producing="" it="" is="" consumed="" by="" insect="" pests,="" causes="" the="" pest="" to="" die.="" bpo1="" does="" not="" produce="" enterotoxin,="" but="" instead="" appears="" to="" enable="" the="" target="" plant="" to="" more="" readily="" and="" efficiently="" uptake="" and="" utilize="" growth="" nutrients.="" bpo1="" is="" a="" true="" growth="" regulator="" and="" to="" our="" knowledge="" does="" not="" have="" classic="" pesticidal="" activity.="" maximum="" anticipated="" application="" rates="" are="" 0.75="" g/a/year="" (cotton)="" and=""><20 g/a/year="" (major="" row="" crops="" including="" soybeans="" and="" corn).="" based="" on="" the="" above,="" it="" is="" therefore="" felt="" that="" bpo1="" should="" not="" be="" considered="" similar="" to="" existing="" bacillus="" products.="" f.="" safety="" determination="" 1.="" u.="" s.="" population.="" since:="" (a)="" the="" maximum="" currently="" sought="" use="" rate="" is="" 0.75="" g="" bpo1/a/year="" for="" use="" on="" cotton="" (and="" 20="" g/a/year="" on="" other="" row="" crops="" for="" which="" registration="" applications="" have="" not="" been="" submitted),="" (b)="" the="" associated="" anticipated="" minute="" residue="" levels="" are="" extremely="" unlikely="" to="" add="" appreciably="" to="" the="" natural,="" indigenous="" background="" levels="" of="" bacillus="" cereus,="" (c)="" bpo1="" does="" not="" produce="" enterotoxin,="" and="" (d)="" the="" toxicity/pathogenicity/infectivity="" studies="" show="" virtually="" no="" negative="" effects,="" bpo1="" should="" be="" considered="" safe="" when="" used="" on="" raw="" agricultural="" commodities="" and="" meets="" the="" reasonable="" certainty="" of="" no="" harm="" requirement.="" 2.="" infants="" and="" children.="" as="" previously="" discussed,="" based="" on="" the="" minuscule="" quantities="" of="" bpo1="" used,="" its="" lack="" of="" toxicity="" and="" pathogenicity,="" and="" its="" mode="" of="" action,="" it="" is="" exceedingly="" improbable="" that="" infants="" or="" children="" would="" be="" at="" greater="" risk="" to="" bpo1="" exposure="" than="" would="" adults.="" bpo1="" should="" be="" considered="" safe="" when="" used="" on="" raw="" agricultural="" commodities="" and="" meets="" the="" reasonable="" certainty="" of="" no="" harm="" requirement.="" 3.="" endocrine="" effects.="" there="" is="" no="" evidence="" that="" bpo1="" has="" endocrine="" disrupter="" effects="" individually="" or="" in="" combination="" with="" any="" other="" chemical.="" it="" is="" unlikely="" to="" be="" an="" endocrine="" disrupter="" or="" to="" have="" a="" synergistic="" endocrine="" effect="" in="" combination="" with="" other="" chemicals.="" g.="" existing="" tolerances="" 1.="" existing="" u.s.="" tolerances="" or="" exemptions="" from="" the="" requirement="" of="" a="" tolerance.="" there="" are="" no="" current="" tolerances="" or="" tolerance="" exemptions="" for="" bacillus="" cereus="" strain="" bpo1.="" 2.="" international="" tolerances="" or="" exemptions="" from="" the="" requirement="" of="" a="" tolerance.="" there="" are="" no="" codex="" maximum="" residue="" levels="" or="" tolerance="" exemptions="" for="" bacillus="" cereus="" strain="" bpo1.="" [fr="" doc.="" 97-16358="" filed="" 6-24-97;="" 8:45="" am]="" billing="" code="" 6560-50-f="">
