Dear Cooperator:
SUBJECT: VOLUNTARY CANCELLATION OF PHOSPHAMIDON
CIBA-GEIGY has decided to phase out from its product line insecticides
containing the active ingredient phosphamidon. Phosphamidon has been
marketed under the trade name Swat(TM) for control of insects and mites
on cotton and under the name phosphamidon for control of aphids on
apples.
CIBA-GEIGY notified the Environmental Protection Agency on May 30, 1990,
that it would like to voluntarily cancel its phosphamidon registration.
High registration and reregistration costs, and limitations on our
research and development budget, are major factors in decisions to
continue to support product registrations and develop new products. As
a result, we are not able to devote our limited resources to satisfying
the regulatory requirements for products with relatively low farmer
demand, such as phosphamidon. In addition, there are other viable
alternatives for use in the cotton and apple markets to control the
insect pests controlled by phosphamidon.
Phosphamidon will continue to be sold by CIBA-GEIGY at least until May
1991 or until inventories are depleted, whichever comes first. After
that, distributors and dealers may continue to sell phosphamidon to
which they have title. Phosphamidon application by farmers will also be
permissible.
If you have any questions on this action, please feel free to call me at
(919) 632-2171.
Sincerely yours,
J. F. Ellis, Ph.D.
