Summaries of Petitions

    Petitioner summaries of the pesticide petitions are printed below 
as required by section 408(d)(3) of the FFDCA. The summaries of the 
petitions were prepared by the petitioners and represent the views of 
the petitioners. EPA is publishing the petition summaries verbatim 
without editing them 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.

1. GlobeTech Industries Corporation

PP 7E4810

    EPA has received a pesticide petition (PP 7E4810) from GlobeTech 
Industries Corporation, 57 Pratt Street, Suite 504, Hartford, CT 06103 
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 to establish 
an exemption from the requirement of a tolerance for Crezasin when used 
as an inert ingredient in pesticide formulations applied to growing 
    EPA has determined that the petition contains data or information 
regarding the elements set forth in section 408(d)(2) of the FFDCA; 
however, EPA has not fully evaluated the sufficiency of the submitted 
data at this time or whether the data supports granting of the 
petition. Additional data may be needed before EPA rules on the 

A. Toxicological Profile

    The toxicity of Crezasin has been studied in Russia and the 
territories of the Former USSR for a period of 20 years on insects 
(bees, silkworms,) birds (chickens, ducks, turkeys), rabbits, dogs, 
sheep, swine and cattle and on an international level with companies 
from Japan, Mongolia, France, USA, Bulgaria, Hungary, and Poland. The 
results of experiments on the toxic effects of Crezasin on different 
animals indicate that the preparation has low toxicity with weakly 
defined cumulation and has a high index of safe application, 
LD<INF>50</INF>= 3,600 +/- 320 milligrams/kilogram in laboratory female 
mice and LC<INF>50</INF>= 6,570 +/- 150 milligrams/kilogram in 
laboratory female rats. The 50% lethal concentration (LC<INF>50</INF>) 
of Crezasin in water for Daphnia is 221.5 milligrams/liter.

B. Aggregate Exposure

    The usage pattern for Crezasin includes an economical effect on a 
limited number of agriculture cultures including potatoes, tomatoes, 
grapes and cereal grains (wheat, barley and oats). Practical usage of 
Crezasin is for the treatment of seeds and foliar spraying of plants. 
Rates of seed treatment of agricultural crops is between 2 - 10 grams 
per metric tons of seeds. Applications higher than 10 grams/ton can 
result in a reduced economic benefit of usage. For spraying of growing 
plants, the recommended dosage rates are between 0.32 x 10<SUP>-4</SUP> 
moles/liter (100 mg/liter) and 0.06 x10<SUP>-4</SUP> moles/liter (20 
mg/liter) of Crezasin, with working solution rates up to 166 liters/
acre (400 liters/hectare). Application rates higher than 
10<SUP>-4</SUP> moles/liter have resulted in a reduced economic 
benefit. The usage of Crezasin in ornamental plants, lawn care and 
other decorative public landscaping has not resulted in an economical 
or biological benefit, and thus its usage would not be found in these 
    Relating to the mobility and persistence in soils. Crezasin is 
considered easily soluble in water at 100 grams/liter at pH 7, 25 
degrees C. Crezasin is considered moderately stable in water, at pH 7, 
25 degrees C, 50% hydrolysis of Crezasin in water is observed in 8.59 
days, 95% hydrolysis is observed in 43.5 days. The constant of 
hydrolysis in neutral water is: C<INF>1</INF><SUP>25</SUP> = 0.05 
day<SUP>-1</SUP>. The persistence of Crezasin in soils, pH 5 - 8, 
organic matter content 1% - 4%, at 20 degrees C: 50% Crezasin 
degradation is observed in 16 days and 90% degradation is observed in 
23.5 days.

C. Safety Determination

    Based on the very low level of substance toxicity, relatively short 
period of environmental fate and its usage pattern which results in low 
concentration usage, Crezasin exhibits very minimal risk exposure both 
in dietary and non-occupational exposures to children.

D. International Tolerances

    There are no Codex maximum residue levels established for residues 
of Crezasin.
