Clothianidin 100 microg/mL in Acetonitrile. Clothianidin is a "systemic" pesticide that is applied as a seed treatment and subsequently spreads to all parts of the plant. As a neonicotinoid type of pesticide, clothianidin attacks the central nervous system of an insect. Seed treatment uses of clothianidin, corn in particular, have been revoked or suspended in Germany, Italy and Slovenia. Bobwhite quail eggshell thickness was affected when the test birds were given a diet consisting of relatively large amounts of clothianidin-treated seeds. Clothianidin is one of seven insecticides within the neonicotinoid class; it has low mammalian toxicity and is primarily used against piercing–sucking insects of major crops [ 19, 20 ]. endobj Neonicotinoids were developed to replace nicotine, which is an effective insecticide but degrades too rapidly to be practical for large-scale use. Active Ingredients: Clothianidin 0.25% Insecticide Mode of Action: 4A Insecticide Class: Neonicotinoids EPA Signal Word: CAUTION / … When extrapolated to humans, these results suggest that clothianidin is moderately toxic through oral exposure, but toxicity is low through skin contact or inhalation. kg/acre or mg/seed), requiring buffer zones around treated fields to protect water supplies, and prohibiting the use of low-technology seed treatment methods or equipment that can send clouds of clothianidin dust or spray up into the air during seeding operations.[3][4][21][62]. stream The study found: "clothianidin elicited detrimental sub-lethal effects at somewhat lower doses (0.5 ng/bee) than imidacloprid (1.5 ng/bee). GROUP4AINSECTICIDE GROUP4AINSECTICIDE However, EPA assessments show that exposure to treated seeds through ingestion may result in chronic toxic risk to non-endangered and endangered small birds (e.g., songbirds). According to the research report, the neonicotinoids, which contain the active ingredient imidacloprid, and similar other chemicals, such as clothianidin and thiamethoxam, are being studied for a possible link to CCD. It is considered to be toxic to aquatic invertebrates if disposal of wastes according to disposal instructions are not followed. Have the product container or label with you when calling a poison control center or doctor, or going for treatment. [28] Beginning in 2006, beekeepers in the United States began to report unexplained losses of hives — 30 percent and upward — leading to a phenomenon called colony collapse disorder (CCD). ent] clothianidin + 8 g a.i. Quick overview Arena 0.25 G Granular Clothianidin Insecticide Provides the best control and the longest-lasting residual out there. When applied as directed, CLOTHIANIDIN INSECTICIDE provides residual insect control. [60] The changes in EPA's classification of this study have no effect on the regulatory status for clothianidin in the U.S. because the study does not provide data with which EPA can legally justify altering its 2003 registration decision. Types of Formulations: 96% technical product 48% flowable concentrate end-use product [34][35], Honey bees and other pollinators are particularly sensitive to clothianidin, as evidenced by the results of laboratory and field toxicity testing and demonstrated in acute poisoning incidents in France and Germany in 2008, and in Canada in 2010 and 2013[citation needed] associated with the planting of corn seeds treated with clothianidin. The research showed that the insecticides were present at high concentrations in waste talc that was exhausted from farm machinery during planting and that is left outside after cleaning the planting equipment. <> For corn, choose from the broad protection of the Poncho® seed treatment family to find the right clothianidin application rate for your operation. #[�>�_��V��}ů��aŤT���no�.���jW���%Kb�Q`ߙD'X�C��H*5�>>"��V\7������M&�Mjq�[ܘ0n8�n8-�����Q��������=���&E�S�!r�����ʐ !���\#��� \�W"aQ5�E� ��� ��4�qqb���"��uW� S��딼�c� endobj It is very persisent in soil and water. ����U��W�t�T������K��T�E�7�=t�\/�&q2������/���egd^�A�lj��`��L�c� �F���w0�����ܹ۷ >�)�`U�M{�ĮMH��A�l�be���\Zx�����Z��E���3L�S�i�s*&�jr�TJ �:�ֱ��i�7 ^�"#8�"�٦ح,(��$V��w������#!%�U��9 ܐ�il��=5�: [29][30][31][32], The Australian Pesticides and Veterinary Medicines Authority notes that clothianidin ranks "among the most highly acutely toxic insecticides to bees" through contact and oral exposure. endobj Arena works as both a preventive and a curative, for outstanding control of chinch bugs, white grubs and a broad spectrum of other turf and ornamental pests with a single application. 4 0 obj C18508. x����o�6����T,4S�i��-�2��b+�Q��l�@��)Q)�Na(f�_2�玼;rq���wŲFo�.��X>�+�uq]=}[\�|*W��z[��j��z����>=Y�JQ�s���NO("�E�Ĕ���@׏ ���F������S�>}<=���������4����f��R�c�Mh���Wfv�.~���`� Jc�^2�H0���C�R�s�9�rj�Le�L��\b�3��+OO�y��-;�aP��X)D��5j#�{3hgX��Ɋ�v ����mפ_(���(�S It poses lower risks to mammals, including humans, when compared to organophosphates and carbamates. 楁 �cl��e��u�:?��������!�_?L���`F$�g+���05{�(��r�1���z���`��R���+�����(�t�Xe�K�0�.�SLX�WS�3`Ǧ���sy�Y]l�C}6y��+ش�i�V��������C#�t�cw�-G8�U%S�th���-��l��Ѕ��zu$�y���=�kz��Yd�� �N!o�D�l�/ [16][17], In 2012, arguing that after more than 9 years the EPA continues to maintain the registration status for clothianidin despite the fact that the registrant has failed to supply satisfactory studies confirming its safety, an alliance of beekeepers and environmental groups filed a petition on March 21 asking the EPA to block the use of clothianidin in agricultural fields until they have conducted a review of the product. [66], In February 2018, the European Food Safety Authority published a new report indicating that neonicotinoids pose a serious danger to both honey bees and wild bees. SYSTEMIC INSECTICIDE POISON KEEP OUT OF REACH OF CHILDREN READ SAFETY DIRECTIONS BEFORE OPENING OR USING ACTIVE CONSTITUENT: 500 g/kg CLOTHIANIDIN For the control of mealybug, woolly aphid and codling moth in apples and pears, green peach aphid and oriental fruit moth in peaches and nectarines, mealybug in grapes, Queensland and Mediterranean Fruit Fly in table … [51][52][53][54][55][56][57][58] Supplemental studies are ones that don't definitively answer uncertainties but still provide some data that might be useful in characterizing risk. In a November 2007 memo EPA scientists declared the study “scientifically sound,” adding that it, “satisfies the guideline requirements for a field toxicity test with honeybees.”[3][15], Clothianidin continued to be sold under a conditional registration, and in April 2010 it was granted an unconditional registration for use as a seed treatment for corn and canola. [50] Studies submitted by Bayer AG to USEPA have provided some useful information about clothianidin's potential long-term effects on honey bees but outstanding questions remain. Sugar beet seed treatment is not currently registered. �y��xs� endstream The petitioners state that they are aware that the EPA has moved up its registration review of clothianidin and other neonicotinoids in response to concerns about their impacts on pollinators, however they note that this process is projected by the EPA to take six to eight years and is thus grossly insufficient to address the urgency of the threat to pollinators. [17] An international group of pesticide regulators, researchers, industry representatives, and beekeepers is working to develop a study protocol that will definitively answer remaining questions about the potential long-term effects on bee colonies and other pollinators. Toxicity varies depending on whether the exposure occurs on a short-term (acute) or long-term (chronic) basis. endobj [65], Following on the release of the EFSA report in January 2013, the UK Parliament has asked manufacturer Bayer Cropscience to explain discrepancies in evidence they have submitted to an investigation. According to the Environmental Protection Agency (EPA), in addition to potential effects on worker bees, there are also concerns about lethal and/or sub-lethal effects in the larvae and reproductive effects in the queen from chronic exposure. [21][22][23][24][25][26], In the 2003 United States EPA assessment report it was stated that clothianidin should not present a direct acute or chronic risk to freshwater and estuarine/marine fish, or a risk to terrestrial or aquatic vascular and nonvascular plants. <> [4][11][16][19][20], Because it is systemic, persistent and highly toxic to honey bees, the Canadian Pest Management Regulatory Agency has requested additional data to fully assess the potential effects of chronic exposure of clothianidin, resulting from its potential movement into plant pollen and nectar. 13 0 obj To reduce the possibility that birds and small mammals might eat treated seeds, users are required to ensure that soil covers planted seeds and that any spilled seed is picked up. [18], Regulatory authorities describe the toxicological database for clothianidin as "extensive", and many studies have been reviewed to support registrations around the globe for this chemical. Labels will be amended following the re-evaluation implementation schedule described under the next section. Clothiandian harms honeybees. Neonicotinoids also replaced older pesticides that were harmful to humans and other mammals. They note that the doses taken up by bees are not lethal, but they are concerned about possible chronic problems caused by long-term exposure. CAS-210880-92-5. Talc is used in the vacuum system planters to keep pesticide treated seeds flowing freely and was studied by the investigators since the waste talc can be picked up by the wind, and could spread the pesticide to non-treated areas; they did not however investigate whether and how much pesticide spreads this way. stream <> However, according to the EPA, the use of sticking agents to reduce dust from treated seeds is standard practice in the U.S.[40][41], In a July 2008 German beekill incident, German beekeepers reported that 50 to 100 percent of their hives had been lost after pneumatic equipment used to plant corn seed blew clouds of pesticide dust into the air, which was then pushed by the wind onto neighboring canola fields in which managed bees were performing pollinator services. Clothianidin users are also required to monitor the weather and not use the chemical or seeds treated with it on windy days or when rain is forecast. Bayer still markets the insecticide for seed treatment uses under the Poncho brand. ��p��B(�8SH—�B��Ql���R�9���� �5f�?H��,Y���)e�:�:���L�����_�T6��Í}�S�F=�+f���8��6����7*p��v 4�q;M��x�)�ʗ:������LcM� q���;@�y��&B7�s@@4V�'���\z��.����9�R>U�zWO9�=�dX��V@��e�O�"V\Ђ�>2�X���F�A��X��:��(f��0��m� :6�8��������i,_3�#�p4� �*�D a��Q&DA/h�� ��%1G�-��Ƅ��WQ��RB!��)�T8�hij�Oe]P�>T��By$�`rimfG���m��y�s ��XM��C�qA�} ��h,�^Ӹ����Ni��8g�Lh�i[F2e�BQ�c�����A�i|��L2`a�Sa�c� Clothianidin, PESTANAL(R), analytical standard (E)-1-(2-Chloro-1,3-thiazol-5-ylmethyl)-3- methyl-2-nitroguanidine (clothianidin) Don’t settle for insecticides that give up on control early.

CLOTHIANIDIN INSECTICIDE is a broad spectrum insecticide for control of a wide spectrum of insect pests infesting turfgrass, potato, pome fruit, grape, strawberries,cucurbit vegetables and stone fruit. Toxicity varies depending on whether the exposure occurs on a short-term (acute) or long-term (chronic) basis. The study was not completed until 2007. The chemical may be used to protect plants against a wide variety of agricultural pests in many countries, of which the following are mentioned in citable English-language sources: Australia, Austria, Belgium, Bulgaria, Canada, Czech Republic, Denmark, Estonia, France, Finland, Germany, Greece, Hungary, Italy, Ireland, Japan, Korea, Lithuania, Netherlands, New Zealand, Poland, Portugal, Serbia, Slovakia, Slovenia, Spain, UK, and the United States.
