Due to permethrin’s low persistence, low water solubility, and strong sorption, the potential for permethrin to move to groundwater is very low. Autoignition Pt: No data. Permethrin is almost insoluble in water (0.2 mg/litre at 30°C), but is soluble in organic solvents such as acetone, hexane, and xylene. In a well-oxidized soil, permethrin is gone in 19d at all pH levels; however, under reducing conditions, 33% of applied permethrin disappeared in 26d at pH5 but 66% was gone in the same amount of time at pH8. ;���Z��T�����$�AvF��^EzA�V��aU�����i%��TOw�&�zU9:$|���V �M�U6[{�Ԍ��V�f�3̍����}s3�(���y�K�o��g]��mQ��5��r����&�IϪ�5��g�M�VlY��L'1/A�R�3}�������#���[ۗ֎�2��8�.��f"҃�q��T=��,P��u��\�0$A���eH0:rF���Cce0F�����*Ѕ4R�I˥Ne�!+y��`���:9�~�����WR ���ӽ�KȲx�Y�k��O&�B�XȜޯ$tF� ����I ��1���)6pń9�ӷ�Um뱈I٨��Ҵ�}��w�V�6 l]���8s�8h�w���犎nr�۠?5��p�,j�1�=]�'G��������r\~�����ޢ��5��s-�t<5N�N;\S�ٚ|ξv�$����Ct���, Because of advances in scientific knowledge, the law requires that pesticides, which were first registered before November 1, 1984, be reregistered to ensure that they meet today’s more stringent standards.

Surface … 0000069140 00000 n It is more stable in acid media than in alkaline media. ln Europe, permethrin is also registered in combination with piperonyl butoxide (see IARC, However, the poor water solubility of permethrin seriously limits its wider clinical applications. This modification is accompanied by an increase in activity of an order of magnitude, and indeed all commercial Type II compounds have an α-cyano group in conjunction with a 3-phenoxybenzyl alcohol moiety.

Uses: Deltamethrin is a broad-spectrum insecticide. Santa Barbara County Offices. Because permethrin binds very strongly to soil particles and is nearly insoluble in water, it is not expected to leach or to contaminate groundwater. If eye irritation persists: get medical advice. 0000005637 00000 n Some of the most common crops permethrin is used on include fruits, nuts, cotton, vegetables, mushrooms and potatoes. Permethrin is more persistent in sediment, as well as in soil where it can have a half-life of 5 to 42 days. water. A pyrethroid insecticide commonly used in the treatment of lice infestations and scabies. The correct amount varies greatly based on the desired results. 0000066448 00000 n In humans, a mild topical derivative of the pesticide is used to treat scabies and lice. The first draft of Permethrin in Drinking-water, Background document for development of WHO Guidelines for Drinking-water Quality, was prepared by Dr P. Toft, Canada, to whom special thanks are due.
