Request From: Steve Toth
Date Requested: May 05, 2008
Request: State Contacts: Note the following request from EPA for information on the use of carbaryl in floriculture OUTDOORS and WEST OF THE MISSISSIPPI RIVER. For those states west of the Mississippi River, please submit any responses from your experts/stakeholders to the Southern Region IPM Center's Information Request Monitoring System by the MAY 19, 2008 deadline. Thanks. Steve Toth -------------------------------------------------- Pesticide Information Request Active Ingredients: Carbaryl Crops/Target sites: Floriculture—outdoors and West of the Mississippi River. The following questions are related to the production of and use of irrigation in outdoor floriculture west of the Mississippi River, and the use of carbaryl in these production systems. EPA realizes the difficulty is making general statements about floriculture production, given the wide range of floriculture crops grown, and growing conditions in this large and diverse region of the country. We are most interested in those areas of outdoor floriculture production that receive relatively little rainfall. Please highlight by state or region. Questions: 1. What outdoor floriculture occurs in your area? 2. What is the average precipitation (inches/year) in your production area? 3. If average precipitation is less than 25 inches/year, is irrigation being used in outdoor floricultural production? a) If yes, go to 4 b) If no, go to 5 4. Irrigation in outdoor floricultural production. a) What type of irrigation is being used for outdoor floriculture (e.g. overhead, drip, furrow, etc)? b) What percentage of each type of irrigation is being used? c) How often does irrigation occur (e.g. daily, twice daily, weekly, etc.)? d) Are there critcal periods for irrigation, and if so, when? e) How much additional water is applied by irrigation (inches/year)? 5. Is carbaryl relied on for insect control in outdoor floricultural production in this area? a) If yes, go to 6 b) If no, got o 7 6. Carbaryl usage information for outdoor floriculture. a) What are the primary target pests being controlled with carbaryl? b) What is the carbaryl application rate being used? c) Are there critical periods for carbaryl use, and if so, when? d) What is the timing of last carbaryl application before harvest (day, days, weeks, etc.)? e) What is longest acceptable re-entry interval (REI) for carbaryl use? f) What alternative insecticides to carbaryl are available to control the primary pests? 7. Thank you for your time and help. Please Respond to: Donald Atwood at atwood.donald@epa.gov Al Jennings at allen.jennings@usda.gov Deadline: May 19, 2008

Response: The following answers were provided by Dr. Dale Pollet, Department of Entomology, Louisiana State University: 1. What outdoor floriculture occurs in your area? Container production of herbaceous perennials, garden mums. Small amount of cut flower production. 2. What is the average precipitation (inches/year) in your production area? 50-60 inches 3. If average precipitation is less than 25 inches/year, is irrigation being used in outdoor floricultural production? a) If yes, go to 4 b) If no, go to 5 4. Irrigation in outdoor floricultural production. a) What type of irrigation is being used for outdoor floriculture (e.g. overhead, drip, furrow, etc)? Overhead sprinkler irrigation with some drip irrigation in cut flower production. Some hand watering. b) What percentage of each type of irrigation is being used? Overhead – 80%, Hand – 15%, Drip – 5% c) How often does irrigation occur (e.g. daily, twice daily, weekly, etc.)? Daily or twice daily d) Are there critcal periods for irrigation, and if so, when? Yes, summer of dry years when rainfall is lacking or not evenly distributed. June – September. e) How much additional water is applied by irrigation (inches/year)? 20-30 inches 5. Is carbaryl relied on for insect control in outdoor floricultural production in this area? a) If yes, go to 6 b) If no, got o 7 Very little, occasionally for eriophyid mites or slugs and occasional beetle problems. On an as needed situation. 6. Carbaryl usage information for outdoor floriculture. a) What are the primary target pests being controlled with carbaryl? b) What is the carbaryl application rate being used? c) Are there critical periods for carbaryl use, and if so, when? d) What is the timing of last carbaryl application before harvest (day, days, weeks, etc.)? e) What is longest acceptable re-entry interval (REI) for carbaryl use? f) What alternative insecticides to carbaryl are available to control the primary pests?
