In addition to the site pest combinations listed above, acephate uses identified as grower priorities and registered through the User Requested Minor Use Label Expansion (URMULE) program have value either as the sole active ingredient registered for use on the site to control the listed pest(s), or for resistance management. The registration of certain uses of insecticide acephate in Canada is proposed for cancellation. Most uses of acephate have value in the food and non-food agriculture industry and are not of concern to human health or the environment when used according to revised label directions. Therefore, acute exposure from acephate and methamidophos in food and drinking water are not of concern provided that the mitigation measures outlined in Section 3.4.1 of PRVD2016-01 are implemented. IDENTIFICATION OF THE SUBSTANCE Product Name ACEPHATE 750 SP Insecticide Common Name Acephate Active Ingredient: Acephate (BSI, E-ISO, ANSI, ESA, BPC), (m)(F-ISO, JMAF) Chemical Name: O,S-dimethyl acetylphosphoramidothioate (IUPAC) CAS N o.: 30560-19-1 The PMRA conducted a risk assessment for acephate in 2004 based on available information at the time and published a proposed re-evaluation decision for public consultation (PACR2004-40). The pellet formulation has since been registered for use on tobacco only. Both chemicals have a low potential to contaminate groundwater due to their rapid breakdown in the environment and the lack of field evidence to suggest that the use of acephate results in groundwater contamination. The public, including the registrant and stakeholders are encouraged to submit additional information that could be used to refine the environmental risk assessment during the 90-day public consultation periodFootnote 1 upon publication of this proposed re-evaluation decision. Active Ingredients: Acephate 98% Subsequently, the technical registrants of methamidophos voluntarily discontinued all methamidophos products and the registrations expired in 2012. Methamidophos, the primary metabolite of acephate, was not fully considered in the acephate risk assessment since a concurrent risk assessment for methamidophos as a registered active ingredient at the time was being conducted. As a result, this causes a build-up … However, when the proposed mitigation measures such as lowered application rates and revised restricted-entry intervals (REIs) are considered, the risk estimates for postapplication workers are not of concern. Acephate is an insecticide that belongs to the organophosphate group of chemicals.It is typically used as a foliar spray against chewing and sucking insects, such as aphids, leaf miners, Lepidopterous larvae, sawflies, and thrips on fruits, vegetables, potatoes, sugarbeet, vines, rice, hops, ornamentals, and greenhouse crops like peppers and cucumbers. Acephate is considered toxic to bees with an LC 50 of 1.2 μg per bee. At the time that the re-evaluation decision is made, the PMRA will publish an Evaluation Report on acephate in the context of this re-evalulation decision (based on the Science Evaluation of Proposed Re-evaluation Decision PRVD2016-01, Acephate). For tree implant cartridges, exposure and risk were not of concern when used as per label directions, since applicator exposure was minimal. Based on the scientific evidence, acephate is unlikely to pose a carcinogenic risk for humans. During the comment period for PACR2004-40, the registrant indicated that a pellet formulation would be an alternative to a closed system for the soluble powder formulation. For enquiries, contact us. An acceptable daily intake is an estimate of the level of daily exposure to a pesticide residue that, over a lifetime, is believed to have no significant harmful effects. This cumulative risk assessment will consider potential exposure to all organophosphate pesticides causing toxicity in the same manner. Acephate did not cause birth defects in animals and adverse reproductive outcomes were only noted following exposure to high levels. Before making a final re-evaluation decision on acephate, the PMRA will consider any comments received from the public in response to Proposed Re-evaluation Decision PRVD2016-01, Acephate. All products containing acephate registered in Canada are subject to PRVD2019-04.

Uses • Acephate is an organophosphate insecticide currently registered for use on a variety of field, fruit, and vegetable crops (e.g., cotton, tobacco, cranberries, mint); in food handling Acephate is an organophosphate insecticide. Since Acephate is an Organophosphate insecticide, the chemical works by blocking an enzyme in the nervous system, thus interrupting the essential processes that help the insect communicate with muscles and with other nerves. The PMRA is requesting feedback on the use pattern for these uses. Cancellation of airblast and outdoor mistblower applications, which are currently registered for use on various trees and ornamentals, and in Christmas tree plantations, farm woodlots, nurseries, shelter belts, right of ways and municipal parks, Cancellation of the highest foliar application rate (resulting from the cancellation of applications by airblast/mistblower, the only method for which the highest rate is registered), Uses in farm woodlots, shelter belts, rights of way and municipal parks are limited to spot treatments using hand-held equipment only, Precautionary and hazard statements to inform users of the toxicity and potential risk of acephate to pollinators, beneficial arthropods, birds, mammals, and aquatic organisms, Label statements directing users to avoid application during periods of bloom or during the 9-day period before crop bloom for crops that are attractive to pollinators (or for other crops when using managed bees for pollination services), Statements directing users that tree injection applications must be made after the blooming/pollen shedding period, A label statement directing users not to discharge acephate-contaminated effluent from greenhouses into aquatic environments, Precautionary label statements informing users of ways to reduce the potential for runoff. When using this formulation, target MOEs were not achieved for most scenarios based on current label directions for various application equipment. For enquiries, contact us. Proposed protective measures to reduce worker exposure require consultation with user groups to determine their acceptability. ACEPHATE 75 SP is an insecticide for control of pests on selected agricultural crops and in certain non-crop areas. Each MRL value defines the maximum concentration in parts per million (ppm) of a pesticide allowed in/on certain foods. Residues in drinking water were based on modelling data. For foliar applications to trees and ornamentals in residential areas, quantitative estimates of exposure and risk were determined for both acephate and methimidophos based on the available data, or using standard defaults in the absence of data. This label direction can be removed if data are submitted to estimate exposure and demonstrate no risks of concern. The active ingredient in Acephate 90% SP is absorbed by plants via the roots and foliage to provide systemic control of feeding insects. 630 Freedom Business Center, Suite 402. Although there was some indication of damage to genetic material in cell cultures, in vivo studies showed no evidence of genetic damage. The re-evaluation decision document will include the final re-evaluation decision, the reasons for it and a summary of comments received on the proposed re-evaluation decision with Health Canada’s responses. What is the proposed Re-evaluation Decision? Re-evaluation draws on data from registrants, published scientific reports, information from other regulatory agencies and any other relevant information available. It is used on food crops, citrus trees, as a seed treatment, on golf courses, and in commercial or institutional facilities. The estimated acute exposure for acephate and methamidophos in food and drinking water was of concern based on initial modelled drinking water concentrations. To obtain a full copy of Proposed Re-evaluation Decision PRVD2016-01 Acephate please contact our publications office.

In case of contact with skin, wash with soap and water. It also can be applied as a separate treatment using enough water to give adequate coverage of the seed. Acephate O,S-Dimethyl acetylphosphoramidothioate . Toxicology studies in laboratory animals describe potential health effects from varying levels of exposure to a chemical and identify the dose at which no effects are observed. With refined modelled drinking water concentrations, the estimated chronic exposure ranged from 1-3% of the ADI for acephate and 1-2% of the ADI for methamidophos for the various population subgroups. Currently, the main product available for foliar applications in various agricultural and horticultural scenarios is packaged as a soluble powder. You will not receive a reply. Should you require further information please contact the Pest Management Information Service. Use on potatoes is proposed for cancellation. When using the pellet formulation with the various application equipment, the calculated MOEs meet the target MOE with minimal mitigation, such as baseline PPE for most crops and a respirator for a few specific uses. Some naturally occurring insect biotypes resistant to TITAN Acephate 970 SG Insecticide and other Group 1B insecticides may exist through normal genetic variability in any insect population. No additional information is required at this time. This is of particular value to producers of ornamental crops as they typically grow a wide variety of plants which require protection from pests that are often uncommon or sporadic in nature. Acephate is a systemic insecticide with long lasting residual activity (typically 10 to 21 days), which is absorbed and transported throughout the plant, thereby protecting the whole plant. As a result of the re-evaluation of acephate, further risk mitigation measures for product labels are being proposed. Acephate 97UP contains a water-soluble systemic insecticide which helps to reduce injury to cotton seedlings by several insects. Acephate is an organophosphate foliar and soil insecticide of moderate persistence with residual systemic activity of about 10–15 days at the recommended use rate. As a requirement of the continued registration for these uses, new risk-reduction measures are proposed to be included on the labels of certain products. Acephate and methamidophos are soluble in water and mobile in soil. These methods and policies also consider the nature of the effects observed and the uncertainties present when predicting the impact of pesticides. Acephate was mildly irritating to eyes and skin and was not found to cause an allergic skin reaction. Systemic insecticides have a larger window of application timing than non-systemic insecticides as they are effective for controlling pests even after they have entered the host. The active ingredient in Acephate 90 WDG is absorbed by plants via the roots and foliage to provide systemic control of feeding insects. By direct application t… No mitigation is required. Details on these considerations are noted in Section 3.4.1 of Proposed Re-evaluation Decision PRVD2016-01, Acephate. To reach its decisions, the PMRA applies hazard and risk assessment methods as well as policies that are rigorous and modern. The resistant individuals can eventually dominate the insect population if … The mitigation measures considered included the removal of acephate use on potatoes, the reduction of application rates and number of applications per season, as well as increasing minimum application intervals for several crop uses. The risk assessment with revised mitigation measures protects against the effects of acephate by ensuring that the level of human exposure is well below the lowest dose at which these effects occurred in animal tests. The active ingredient in Acephate 97UP is acephate, a water-soluble insecticide readily absorbed by plant roots and foliage to give systemic control of feeding insects. It does only list wasps, ants, crickets, earwigs, and pillbugs on the product label for this application, so it would not be the best product … Acephate contributes to pest management in Canadian food crops. Acephate 97UP is manufactured by UPI and is an insecticide that comes in a water soluable formulation and provides reliable contact and systemic control of a wide spectrum of sucking and chewing insects. This label direction can be removed if data are submitted to estimate exposure and demonstrate no risks of concern. The PMRA completed a preliminary risk assessment for methamidophos in 2007 (REV2007-11), and identified potential risks to the environment, to workers during application and postapplication activities, as well as to the general population through food and drinking water exposure. The transfer of uses from the soluble powder product label to the pellet product label is currently in progress. Treatment to trees and ornamentals using implant cartridges, and various methods of tree trunk injection resulting in no contact with the foliage is expected to result in minimum exposure to residential populations such as children and gardeners. Please forward all comments to Publications. This document (Proposed Re-evaluation Decision PRVD2019-04, Acephate and Its Associated End-use Products) presents revisions to the proposed regulatory decision for the re-evaluation of acephate (PRVD2016-01) with risk mitigation measures to protect the environment along with updates to the environmental evaluation on which the proposed decision was based. Acephate is an insecticide registered to control a broad spectrum of insect pests on a wide variety of crops and use sites, including forest and woodlots, terrestrial food and feed crops, and outdoor ornamentals. Crops with minor use registrations identified as having particular value are the following: aphids on celery; blackheaded fireworm on cranberry; and the pipette and syringe application method to trees for the control of sucking and chewing insects. A pellet formulation was determined to be an acceptable alternative to the soluble powder formulation for most uses, which would require registration for the pellet formulation. MRLs are specified for acephate and methamidophos on a wide range of commodities. Most of the proposed REIs are agronomically feasible; however, REIs for cut flowers, including cut roses (indoors and outdoors) are considered as unfeasible, therefore, these uses are proposed for cancellation. Acephate 90% SP is a soluble powder used as an insecticide for control of pests on selected agricultural crops and in certain non-crop areas. Estimates of exposure did not reach the target margin of exposure (MOE) or aggregate risk index (ARI) for adults and children for all postapplication scenarios and are, therefore, of concern. No data was available to assess handler exposure from hand-held mist blowers for mist application in greenhouses. ORTHENE® 97 insecticide's active ingredient, acephate, is readily absorbed by plant roots and foliage to give both contact activity and systemic control of feeding insects in high-value vegetable crops as well as soybean, cotton and tobacco. There are no additional data required under section 12 of the Pest Control Products Act. In the absence of data to estimate risk, a label direction specifying “Not for use with fogging equipment” is required. For uses where changes to the use pattern are proposed as mitigation measures, Health Canada is asking stakeholders to comment on the agronomic feasibility of the proposed changes and the potential impact on the associated pest management practices. Once the final re-evaluation decision is made, the registrants will be instructed on how to address any new requirements. Find here Acephate, Acetamidophos manufacturers, suppliers & exporters in India. It also proposes additional risk-reduction measures to further protect human health and the environment. An ARI of 1 or greater indicates that exposure to both compounds is not of concern. To reduce food and drinking water risk concerns: application rate and maximum number of applications per year are proposed to be reduced, and minimum application intervals are proposed to be increased for certain crops. Insecticide. When acephate is used in accordance with the revised label, the resulting environmental risk posed by acephate and methamidophos is considered to be acceptable. When used according to the revised label directions, acephate does not pose an unacceptable risk to the environment. the levels at which no health effects occur and. Conditions of registration may include special precautionary measures on the product label to further reduce risk. Dendrex (Acephate) Microinjection Insecticide A broad-spectrum systemic insecticide for control of certain insects on trees and shrubs. To protect mixer/loaders/applicators: replacement of the soluble powder formulation with the pellet formulation. Where no specific MRL has been established, a default MRL of 0.1 ppm applies, which means that pesticide residues in a food commodity must not exceed 0.1 ppm. Based on the precautions and directions for use on the current product labels, some postapplication risks to workers performing activities such as thinning, pruning and harvesting of crops, did not meet current standards and are of concern. Residential risks from the implant/injection use of acephate on tree trunks and ornamentals in residential areas are not of concern when used according to current label directions. Based on initial modelled drinking water concentrations, the estimated chronic exposure ranged from 8-36% of the acceptable daily intake (ADI) for acephate and 16-69% of the ADI for methamidophos for the various population subgroups. Used as a contact and systemic insecticide. 171 product ratings - Lot of 2 Ortho 0282210 Orthene 12 Oz. In addition, the test data on which the decision is based will also be available for public inspection, upon application, in the PMRA’s Reading Room (located in Ottawa). It is used on food crops, citrus trees, as a seed treatment, on golf courses, and in commercial or institutional facilities. Acephate What Additional Scientific Information is Being Requested? Acephate 97UP can be mixed in the slurry tank with most of the fungi- cide seed treatments in common use. Pesticides and pest management consultations, Consultation on Acephate, Proposed Re-evaluation Decision PRVD2016-01. Health or environmental risk is considered acceptable if there is reasonable certainty that no harm to human health, future generations or the environment will result from use of or exposure to the product under its conditions or proposed conditions of registration. Acephate is applied using conventional ground application equipment, soil injection, tree trunk injection and implant cartridges by farmers, farm workers and professional applicators. In the absence of data to estimate risk, label directions specifying “Not for use with hand-held mist blowers” and “Automated mist blowers are permitted” are required. Acephate contributes to pest management in the ornamental industry. Proposed REIs range from 12 hours to 20 days. Acephate, and its major transformation product methamidophos, enter the environment when acephate is used to control insect pests on a wide variety of sites, including forests and woodlots, terrestrial food and feed crops, and outdoor ornamentals. Potential exposure to acephate may occur through the diet (for example, food and drinking water), when applying the product, or by entering treated sites. Due to the risk concerns identified, mitigation measures and refinements were considered in the modelled drinking water concentrations.
