Request From: Steve Toth
Date Requested: May 09, 2007
Request: Note the following request for information on nicotine use on nursery and ornamental crops. Please circulate to the experts in your respective states and territories and submit any response to the Southern Region IPM Center Information Requests Monitoring System by Friday, May 25, 2007, and I will forward to EPA and USDA. Thanks. Steve Toth ------------------------------------------------ Pesticide Information Request Active Ingredients: Nicotine Crops/Target sites: Any crops on which nicotine is applied (nursery and ornamental crops are about the only ones where nicotine seems to be important). Questions: On what crops is nicotine used? What pests are the targets for nicotine use? How and when is it applied? What rates or how much is used for any given site? Please Respond to: Colwell Cook at cook.colwell@epa.gov Wilfred Burr at wilfred.burr@ars.usda.gov Deadline: May 25th Background Information: I will attach the message I received from Colwell. Nicotine is coming up for registration review. We are finding very low levels of use, mostly in the ornamental industry, as the product Fulex. I have heard that it is critical to the Poinsettia industry. However, I need more information to describe this use. Could the IPM centers assist in gathering information regarding the Fulex and ornamental industry? Thank you in advance. Wilfred Burr USDA Office of Pest Management Policy

Response: Active Ingredients: Nicotine Crops/Target sites: Greenhouse Questions: On what crops is nicotine used? Greenhouse grown ornamental plans including flowering potted plants and bedding plants. Among these, Poinsettias continue to be the number one US flowering potted plant with an annual wholesale value of more than $242.0 million US$ in 2005 (USDA-NASS 2006). Texas produced more 3.6 million Poinsettia pots with a whole sale value of almost $17.0 million US$ in 2005. What pests are the targets for nicotine use? Whiteflies, aphids, thrips How and when is it applied? Fumigant (example: Fulex nicotine fumigator). It is usually applied as a rescue treatment when pest populations are large and quick action is required before plant sale or to prevent further crop damage. One of the few products that may be used for whitefly control after poinsettia bract formation (color) when plants are highly susceptible to insecticide associated phytotoxicity. One of the only few currently labeled products for western flower thrips control in greenhouses. What rates or how much is used for any given site? One 12 oz can of Fulex nicotine fumigator can treat up to 20,000 cubic feet of greenhouse space. The average Texas grower has an estimated 1.1 million cubic feet of greenhouse space (based on USDA-NASS 2006 data on total number of growers, total area of greenhouse cover, and typical greenhouse shape). If each grower treated 25% of their greenhouse space one time per year, that would translate into approximately 14 cans of nicotine fumigant per year per site. USDA-NASS (2003) estimated 2% of Texas growers used nicotine in 2002; this figure is likely accurate for recent years.

Response: There may a different answer for greenhouse, but nicotine is not used much, if at all, in nurseries. It has few targets that can't be hit by other materials with lower toxicity, even for our occasional "organic" growers. Dr. Will Hudson

Response: As a wholesale distributor of greenhouse growing supplies we sell Fulex Cropfume 105 Nicotine smoke generators to production greenhouse growers that licensed pesticide applicators only. The product is especially important to growers of greenhouse cuccumbers and tomatoes for aphid and thrip control as there are not alot of materials approved for these crops and this one is effective but does not have a residual concern. Growers are striving to use the most rational products and avoid having produce with chemical residues. Nicotine smoke fits this need. I can be reached at ph 540-434-6754 Jon Oliver, Wetsel, Inc.

Response: I see low use, mainly used in greenhouse vegetable production for whiteflies and aphids. I have one to two growers that have used the Fulex product in the two years.

Response: Responses below are from Dr. Schnelle and Mark Andrews of Green Leaf Nursery. Nicotine "bombs" are still used and are effective. But I can't think of any pest that can't be controlled with other compound(s). Mike Schnelle Charles: We don't use any nicotine on the nursery, except by the workers in the form of cigarettes.
