Noncrop (excluding public lands such as forests, parks, recreational areas), Christmas tree plantings, conifer seed orchards, conifer plantations, forest tree nurseries., Pyrethroids are used as insecticides. (L857), Fenvalerate is used as an insecticide, mostly to control insects in food, feed, and cotton products, and for the control of flies and ticks in barns and stables. (L606), Use Classification: Insecticides, Household Products: Information on 34 consumer products that contain Esfenvalerate in the following categories is provided:, • Inside the Home, • Landscaping, Yard, • Pesticides, • Pet Care, Methods of Manufacturing: ... Esfenvalerate can be derived from (S)-2-(4-chlorophenyl)-isovaleroyl chloride and (S)-3-phenoxymandelic acid. It can be prepared most efficiently, however, from the (R, S) alcohol ester of the (S) acid through preferential precipitation ... ., Impurities: The concentrate may contain xylene ... or ethylbenzene ... ., Formulations, Preparations: Emulsifiable concentrate, flowable, ULV liquid, Esfenvalerate is available in the USA as a technical-grade product with a purity of 75%., Pydrin insecticide (Y-rich) is an isomerically enriched form of fenvalerate containing an excess ratio of the active diastereomers SS and RR (designated Y) over the less active diastereomers RS and SR (designated X) at a ratio of approximately 85:15. Fenvalerate contains Y:X in a ratio of 45:55. ..., Esfenvalerate, an A-alpha-isomer-enriched Fenvalerate technical material, For more Formulations, Preparations (Complete) data for ESFENVALERATE (123 total), please visit the HSDB record page., Consumption Patterns: The state of California requires that all pesticide applications (excluding private homeowner uses) be reported. This data is collected in the PUR (pesticide use reporting) database. ... According to the CDPR PUR database, a total of 29, 918 lbs of esfenvalerate were used in California in 2002, 33, 495 lbs in 2003, 30, 817 lbs in 2004, and 32, 566 lbs in 2005. The average annual number of pounds applied over that four-year period was 31, 699. ... Based on the average annual pounds applied between 2002 and 2005, greater than 1000 pounds of esfenvalerate is applied to nine, California, crops annually: almond, peach, walnut, prune, lettuce, and nectarine. Approximately, 20 percent of esfenvalerate is applied to almonds, ten percent is applied to peach, and corn, and seven percent is applied to artichokes., General Manufacturing Information: The WHO Recommended Classification of Pesticides by Hazard identifies Esfenvalerate (technical grade) as Class II: moderately hazardous, Main Use: insecticide., Esfenvalerate has replaced the compound fenvalerate for use in the United States. Much of the data for esfenvalerate is closely applicable to the pesticide fenvalerate because the two compounds contain the same components. The only difference in the two products is the relative proportions of the four separate constituents (isomers). Esfenvalerate has become the principal compound of the two because it results in lower application rates than fenvalerate, is less chronically toxic, and is a more powerful insecticide. The compound contains a much higher percentage of the one insecticidally active isomer (84% for esfenvalerate and 22% for fenvalerate)., Contains approximately 84% of active ingredient ... one of the most widely used pyrethroid insecticides, Esfenvalerate (the alpha-isomer of fenvalerate) has the highest insecticidal activity of the four fenvalerate stereoisomers and it is used as an insecticide (currently replacing those of the fenvalerate isomer-mixture)., ... Fenvalerate consists of about 23% of this isomer. |
