that agencies use to create their documents. on III. In this study, the sensitivity of 89 R. cerealis isolates to different fungicides was evaluated using mycelial growth inhibition assays. 2. Aggregate cancer risk for U.S. population. Consistent with section 408(b)(2)(D), EPA has reviewed the available scientific data and other relevant information in support of this action. Other types of entities not listed in the table could also be affected. If you would like to request a waiver of the tolerance objection fees, you must mail your request for such a waiver to: James Hollins, Information Resources and Services Division (7502C), Office of Pesticide Programs, Environmental Protection Agency, 1200 Pennsylvania Ave., NW., Washington, DC 20460. Its mode of action is to inhibit transport-associated phosphorylation of . Chinese hamster ovary cells were tested with and without metabolic activation from 1.37 to 700 μg/mL. a. Ciba has submitted over 25 separate toxicology studies in support of tolerances for fludioxonil. Statistically significant trend for malignant lymphomas in females. documents in the last year, 532 After calculating DWLOCs and comparing them to the EECs for surface and ground water, EPA does not expect intermediate-term aggregate exposure to exceed the Agency's level of concern, as shown in the following Table 5: Table 5.—Aggregate Risk Assessment for Intermediate-Term Exposure to Fludioxonil. Biochemical. According to Ciba, fludioxonil has a low order of acute toxicity by the oral, dermal, and inhalation exposure routes. Start Printed Page 82934. The linear default risk methodology (Q*) is the primary method currently used by the Agency to quantify carcinogenic risk. Using the exposure assumptions described in this unit for intermediate-term exposures, EPA has concluded that food and residential exposures aggregated result in aggregate MOEs of 1,200 for the U.S. population and 530 for infants/children. Using the exposure assumptions described in this unit for chronic exposure, EPA has concluded that exposure to fludioxonil from food will utilize 3.7% of the cPAD for the U.S. population, 12% of the cPAD for all infants (< 1 year old) and 9.8% of the cPAD for children 1-6 years old. In rats, fludioxonil produced a significant trend and pair-wise increase in hepatocellular tumors, combined, in female rats at doses adequate to assess carcinogenicity. Fludioxonil is an odorless, colorless to yellowish synthetic compound of the phenylpyrrole group of substances. A respirator is not normally required when handling this substance, but in case of chemical aspiration, find a well-ventilated area or go outside where there is fresh air. 2. The registrant has proposed high performance liquid chromatography using ultraviolet detection Method AG-597B as the analytical enforcement method. fludioxonil. It can control peach-potato aphids, flea beetles, and cabbage stem flea beetles. This variation will be taken into account in more refined screening-level and quantitative drinking water exposure assessments. NOAEL = 3.3 mg/kg/day (F) and 33.1 mg/kg/day (M). Thus, TPI is a drug target of the phenylpyrrole class of fungicides, inducing elevated MG which alters HHK . Fludioxonil 95% TC. On the other hand, there was no evidence of carcinogenic potential with fludioxonil in the study in rat models. Together these findings reveals that the sensitivity to fludioxonil is not only positively controlled by the Hog1 pathway, but also mediated by the Chk1, Mps1, Cga1 and Cgb1 pathways. In addition, several Section 18 emergency exemptions for use as a foliar spray on strawberries, caneberries and as a post-harvest spray treatment on apricots, nectarines, peaches, and plums have been approved. allow fludioxonil contaminated waste water from the processing plants to enter lakes, streams, ponds or other waters. While filling the remainder of the spray tank add the required amount of SCHOLAR. Micronucleated hepatocytes were found in Phase II at the low and mid dose levels but not at the high dose level and not in Phase I. Fludioxonil safety. documents in the last year, 829 "There's more to be studied . Therefore, the tolerance is established for residues of fludioxonil 4-(2,2-difluoro-1,3-benzodioxol-4-yl)-1 H-pyrrole-3-carbonitrilein or on grapes at 1.0 ppm, strawberries at 2.0 ppm, dry bulb onions at 0.20 ppm, and green onions at 7.0 ppm. Default body weights and drinking water consumption values vary on an individual basis. There were no comments received in response to the notice of filing. The evidence is inadequate and cannot be interpreted as showing either the presence or absence of a carcinogenic effect.

Risk assessments were conducted by EPA to assess dietary exposures from fludioxonil in food as follows: i. However, the Agency has since received the additional mutagenicity studies and based on the negative preliminary findings of the studies, the fact that the statistical increase in liver tumors in female rats occurred only at the highest dose, the lack of tumorigenic response in male rats and mice, the Agency has concluded that fludioxonil does not pose a significant cancer risk. DWLOCs are theoretical upper limits on a pesticide's concentration in drinking water in light of total aggregate exposure to a pesticide in food and residential uses. ZERO BIAS - scores, article reviews, protocol conditions and more regulatory information on FederalRegister.gov with the objective of It interferes with glucose transport across fungal membranes. Chinese hamsters were orally dosed at levels from 1,250 to 5,000 mg/kg. For toddlers, dermal and non-dietary oral post-application exposures may result from dermal contact with treated turf as well as hand-to-mouth transfer of residues from turfgrass. Introduction: Fludioxonil is a synthetic phenylpyrrole-group substance. documents in the last year, 87 DWLOCs are theoretical upper limits on a pesticide's concentration in drinking water in light of total aggregate exposure to a pesticide in food, and from residential uses. This final rule establishes a tolerance under FFDCA section 408(d) in response to a petition submitted to the Agency. for better understanding how a document is structured but In the Federal Register of March 29, 2000 (65 FR 45498) (FRL-6495-5), EPA issued a notice pursuant to section 408 of the FFDCA, 21 U.S.C. These aggregate MOEs do not exceed the Agency's level of concern for aggregate exposure to food and residential uses. The telephone number for the Office of the Hearing Clerk is (202) 260-4865. For dealing with the fungal diseases, it is usually applied in seed treatment as well as post-harvest treatment of fruits. 131341-86-1 1.2.1. The Dietary Exposure Evaluation Model (DEEM® analysis evaluated the individual food consumption as reported by respondents in the USDA 1989-1992 nationwide Continuing Surveys of Food Intake by Individuals (CSFII) and accumulated exposure to the chemical for each commodity. These tools are designed to help you understand the official document Cymoxanil + Fludioxonil + Metalaxyl-M. 16.11.2022 bis 15.03.2023. gegen Fusarium-Arten, Botrytis cinerea, Falschen Mehltau (Peronospora pisi), Brennfleckenkrankheit (Ascochyta pisi . Based on animal studies, fludioxonil affects the liver, kidneys and the hematopoietic system (blood cells). In one mouse study, there was a significant trend for malignant lymphomas in female mice up to 3,000 ppm.

Based on these risk assessments, EPA concludes that there is a reasonable certainty that no harm will result to the general population, and to infants and children from aggregate exposure to fludioxonil residues. Quality fludioxonil 50%WP 20%FS 2.5%FS fungicide - find quality fungicides, Agrochemicals & Pesticides & fungicides from Shenzhen Sunrising Industry Co., Ltd. of China Suppliers - 127902089. Section 408(b)(2)(A)(i) of the FFDCA allows EPA to establish a tolerance (the legal limit for a pesticide chemical residue in or on a food) only if EPA determines that the tolerance is “safe.” Section 408(b)(2)(A)(ii) defines “safe” to mean that “there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue, including all anticipated dietary exposures and all other exposures for which there is reliable information.” This includes exposure through drinking water and in residential settings, but does not include occupational exposure. Fludioxonil is persistent and may carryover. More information and documentation can be found in our ( 2) Tolerances are established for residues of the fungicide fludioxonil, including its metabolites and degradates, in or on the commodities in the following table. In case of direct contact, immediately flush contaminated eyes with running water for a few minutes. Information about Product Registrations and Transfers. Accordingly, taking into account the data on pre- and post-natal toxicity, EPA determined that an additional tenfold safety factor was not necessary to protect infants and children. Based on the GENEEC and SCI-GROW models the estimated environmental concentrations (EECs) of fludioxonil for acute exposures are estimated to be 46 parts per billion (ppb) for surface water and 0.35 ppb for ground water. Molecular Formula CHFNO. 01/10/2023, 162 An uncertainty factor (UF) is applied to reflect uncertainties inherent in the extrapolation from laboratory animal data to humans and in the variations in sensitivity among members of the human population as well as other unknowns. Five fludioxonil-resistant mutants were subsequently induced by exposure to fludioxonil under laboratory conditions. establishing the XML-based Federal Register as an ACFR-sanctioned It has excellent seed and crop safety, and is labeled for use on a variety of crops.

To reduce runoff from treated areas into aquatic habitats avoid application to areas with a moderate to steep slope, compacted soil, or clay. Document Drafting Handbook Wear chemical-resistant gloves (barrier laminate, butyl rubber, nitrile rubber, neoprene rubber, PVC or Viton), coveralls, socks and chemical-resistant footwear. Short-term inhalation endpoints were identified, however, they are not relevant for the short-term aggregate risk since homeowners would not be applying fludioxonil. The evidence is inadequate and cannot be interpreted as showing either the presence or absence of a carcinogenic effect. Fludioxonil is the active ingredient in registered products used as a seed treatment for many crops (with the exception of tree crops and berries). These markup elements allow the user to see how the document follows the CAS No. LOAEL = 1,000 mg/kg/day based on reduction in corrected weight gain. There is a complete toxicity data base for fludioxonil and exposure data are complete or are estimated based on data that reasonably accounts for potential exposures. The petition requested that 40 CFR 180.516 be amended by establishing tolerances for residues of the fungicide fludioxonil, 4-(2,2-difluoro-1,3-benzodioxol-4-yl)-1 H-pyrrole-3- carbonitrile, in or on grapes at 1.0 ppm. However, the period for filing objections is now 60 days, rather than 30 days. The results showed that all R. cerealis isolates tested were sensitive to iprodione, difenoconazole and fludioxonil with mean . In person. A. Based on the residue data, the recommended tolerance for residues in/on almond is 0.2 ppm and the recommended tolerance for residues in/on pecan is 0.01 ppm. In this study, the effects of fludioxonil on human immune cell viability, apoptosis, cell cycle arrest, and mitochondrial membrane potential were examined in human immune cells, such as Jurkat T cells and Ramos B cells. Office location and telephone number: Rm. However, in a second study up to 7,000 ppm, the limit dose, there was no evidence of carcinogenicity for either sex. The experiments were conducted at Hudiaba research station farm (River Nile State) and New halfa Research Station (Kassala State) for two consecutive seasons 2014/015 and 2015/016, to evaluate the effectiveness of Celest Top 312.5 FS (flowable solution) as seed dressing to control insect pests and seedling diseases of wheat. It is often used in combination with another fungicide such as Cyprodinil. None of these models include consideration of the impact processing (mixing, dilution, or treatment) of raw water for distribution as drinking water would likely have on the removal of pesticides from the source water. The Congressional Review Act, 5 U.S.C. This official record includes the documents that are physically located in the docket, as well as the documents that are referenced in those documents. The rat and rabbit developmental toxicity studies were tested at doses that produced maternal toxicity. EPA will submit a report containing this rule and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of this final rule in the Federal Register. For further discussion of the regulatory requirements of section 408 and a complete description of the risk assessment process, see the final rule on Bifenthrin Pesticide Tolerances (62 FR 62961, November 26, 1997) (FRL-5754-7).

GENEEC incorporates a farm pond scenario, while PRZM/EXAMS incorporate an index reservoir environment in place of the previous pond scenario. Conclusion. Fludioxonil is an effective fungicide widely used for crop protection and is effective against tomato gray mold. The systemic exposure of operators, workers and bystanders to fludioxonil formulated as WG was estimated to be below the established AOEL, as well as for the FS formulation. Animal tests reveal the following side effects of experimental doses of fludioxonil: Fludioxonil is also known be very toxic to aquatic life with long-term effects. What Do I Need to Do to File an Objection or Request a Hearing? Since the models used are considered to be screening tools in the risk assessment process, the Agency does not use estimated environmental concentrations (EECs) from these models to quantify drinking water exposure and risk as a %RfD or %PAD. LOAEL = 113 mg/kg/day (M) and 141 mg/kg/day (F) based on decreased mean body weight gain, slight anemia (F), and increased incidence and severity of liver lesions (degeneration) in both sexes. It can be used to control fungal disease, making it a useful seed treatment as well as a post-harvest treatment for fruit. Dietary exposure from drinking water. fludioxonil " within Products.

El informe define los tipos de Fludioxonil Mercado junto con sus aplicaciones en varias verticales de la industria por diversas regiones y países principales. To estimate risk, a ratio of the NOAEL to exposures (margin of exposure (MOE) = NOAEL/exposure) is calculated and compared to the LOC. When EECs for surface water and groundwater are less than the calculated DWLOCs, OPP concludes with reasonable certainty that exposures to the pesticide in drinking water (when considered along with other sources of exposure for which OPP has reliable data) would not result in unacceptable levels of aggregate human health risk at this time. A Rule by the Environmental Protection Agency on 12/29/2000. Fludioxonil is a broad-spectrum fungicide which is non-systemic with a long residual activity. There is no Inactive Alternate Brand Name. 3. Molecular Weight: 248.19. on NARA's archives.gov. Monoisotopic mass 248.039734 Da. The dermal MOE for postapplication exposure for the hand to mouth scenario is 13,000. Gene mutation in mammalian cells in culture. The EPA classified Fludioxonil as a Group D - not classifiable as to human carcinogenicity. However, the lowest dose at which adverse effects of concern are identified (the LOAEL) is sometimes used for risk assessment if no NOAEL was achieved in the toxicology study selected. An acute dose and endpoint was not selected for the U. S. population (including infants and children) because there were no effects of concern observed in oral toxicology studies, including maternal toxicity in the developmental toxicity studies in rats and rabbits, that are attributable to a single exposure dose. You may obtain electronic copies of this document, and certain other related documents that might be available electronically, from the EPA Internet Home Page at http://www.epa.gov/. 2. EPA has sufficient data to assess the hazards of and to make a determination on aggregate exposure, consistent with section 408(b)(2), for a tolerance for residues of fludioxonil on grapes at 1.0 ppm, strawberries at 2.0 ppm, dry bulb onions at 0.20 ppm, and green onions at 7.0 ppm. Intermediate-term risk. Chronic risk. corresponding official PDF file on govinfo.gov. The emergence. . Initial screening of eleven fungicides (prochloraz, fludioxonil, tebuconazole, penconazole, difenoconazole, tebuconazole, myclobutanil, carbendazim, boscalid + pyraclostrobin, metconazole, flusilazole) showed that fludioxonil was the most effective fungicide against L. theobromae and L. pseudotheobromae in vitro (data not shown). Fludioxonil is a member of the class of benzodioxoles that is 2,2-difluoro-1,3-benzodioxole substituted at position 4 by a 3-cyanopyrrol-4-yl group. No systemic toxicity was seen at the limit dose (1,000 mg/kg/day) in the 28-day dermal toxicity study in rats. Su actividad es por contacto que impide la germinación de conidias y el crecimiento del tubo germinativo y del micelio. The acute or chronic Population Adjusted Dose (aPAD or cPAD) is a modification of the RfD to accommodate this type of FQPA Safety Factor. When Will the Agency Grant a Request for a Hearing? 2.

The mode of action of fludioxonil is the inhibition of transport-associated phosphorylation of glucose as well as preventing glycerol synthesis. 119, Crystal Mall #2, 1921 Jefferson Davis Hwy., Arlington, VA, from 8:30 a.m. to 4 p.m., Monday through Friday, excluding legal holidays. Fludioxonil inhibits transport-associated phosphorylation of glucose as well as preventing glycerol synthesis. The Public Inspection page The term “residential exposure” is used in this document to refer to non-occupational, non-dietary exposure (e.g., for lawn and garden pest control, indoor pest control, termiticides, and flea and tick control on pets). Fludioxonil (211) First draft prepared by Dr Dugald MacLachlan, Department of Agriculture and Water Resources, Australia EXPLANATION Fludioxonil was evaluated for the first time by the JMPR in 2004 when an acceptable daily intake (ADI) of 0-0.4 mg/kg bw was established. For non-dietary risk assessments (other than cancer) the UF is used to determine the LOC. In addition to filing an objection or hearing request with the Hearing Clerk as described in Unit VI.A., you should also send a copy of your request to the PIRIB for its inclusion in the official record that is described in Unit I.B.2.
