Dear Ms. Carr:

Re: Acceptance of Revised Special Local Need Labeling for DuPont Vydate L Insecticide/Nematicide (EPA SLN No.NY-990002)

    The Department has reviewed your application to register revised Special Local Need (SLN) labeling for DuPont Vydate L Insecticide/Nematicide (EPA Reg. No. 352-372) in New York State.

    The revised SLN labeling adds the foliar treatment for onion thrips on bulb onions to the previously accepted SLN for use on bulb onions to control root knot (except Javenese), stubby root, stem and bulb nematodes. The product cannot be used in Suffolk and Nassau Counties (Long Island), New York.

    The Department has received numerous letters which expressed the continued need for the use of DuPont Vydate L Insecticide/Nematicide on bulb onions for the control of root knot, stubby root, stem and bulb nematodes, and for the addition of onion thrips to the SLN labeling.

    Onion thrips damage plants by feeding on leaves, which indirectly reduces yields of onion bulbs. In New York State, up to 100% of onion fields may become infested with onion thrips and in severe situations yield loss may reach 50%. Thrips damage also may predispose onion plants to pathogens such as Alternaria porri, which causes purple leaf blotch disease. Onion thrips in New York State overwinter in and near onion fields and emerge in the spring. Typically, there are 3 to 5 overlapping generations per season. Insecticide use is the only effective tactic known to control this pest.

    Onion thrips infestations have been difficult to control due to insecticide resistance in all New York onion-growing areas. A Special Local Need registration for the use of Vydate L Insecticide/Nematicide to control these resistant populations is needed.

    Therefore, under the authority of Section 24(c) of FIFRA, the Department hereby accepts revised Special Local Need labeling for DuPont Vydate L Insecticide/Nematicide (EPA Reg. No. 352-372) for use on bulb onions to control onion thrips, root knot (except Javenese), stubby root, stem and bulb nematodes. The SLN registration maintains the previous SLN registration number of SLN No. NY-990002 and will expire December 31, 2005.

    The SLN allows use only on bulb onions for control of onion thrips, root knot, stubby root, stem and bulb nematodes. All precautionary statements, applicable use directions, use precautions and limitations of the labeling affixed to the DuPont Vydate L Insecticide/Nematicide (EPA Reg. No. 352-372) container must be followed. The product, DuPont Vydate L Insecticide/Nematicide (EPA Reg. No. 352-372) and (SLN No. NY-990002), is classified as a federally "RESTRICTED USE PESTICIDE," and as noted on the "restriction" column on the certificate, is classified as "restricted use" in New York State. As such, this product is restricted in its purchase, distribution, sale, use, and possession in New York State.

    According to New York State Department of Environmental Conservation Regulations 6NYCRR 326.3(a): "It shall be unlawful for any person to distribute, sell, offer for sale, purchase for the purpose of resale, or possess for the purpose of resale, any restricted pesticide unless said person shall have applied for, and been issued a commercial permit."

    Should you require information to obtain a commercial permit, please contact the Pesticide Certification Section, at (518) 402-8748.

    The Certificate of Pesticide Registration and a copy of the revised New York State stamped "ACCEPTED" SLN labeling for DuPont Vydate L Insecticide/Nematicide are enclosed for your records.

    Please be reminded that a copy of the accepted SLN label must be distributed with all product distributed in New York State and be in the possession of the user at the time of pesticide application.

    Please contact Ms. Jeanine Broughel, of my staff, at (518) 402-8768, if you have any questions.

Sincerely,

Samuel J. Jackling Chief
Pesticide Product Registration Section
