Evaluation of Fulfill(R) 50wg (Pymetrozine) for Cotton Aphid Control in 1998 Field Trials

J. Scott Ferguson, John P. Koenig, Stephen M. White, Dennis M. Dunbar and D. Scott Lawson


 
ABSTRACT

Fulfill® is a selective new insecticide currently under development by Novartis Crop Protection. It has good activity against a wide range of aphid species, including the cotton aphid, Aphis gossypii. Fulfill contains the active ingredient, pymetrozine, which belongs to a new chemical class known as the pyridine azomethines. Pymetrozine exhibits a unique mode of action and is not known to be cross-resistant to any other class of chemistry. Fulfill is compatible for use in cotton IPM and resistance management programs because of its selectivity, low use rate, and unique mode of action. On May 26, 1998 Novartis Crop Protection submitted a petition to EPA requesting registration of Fulfill as a Reduced Risk pesticide on cotton.

Results from 1998 field trials are discussed. In these trials, Fulfill provided good control of the cotton aphid at rates of 2.75 - 4.0 oz/A. Fulfill applied at a rate of 2.75 oz/A also provided good control of the cotton fleahopper in one trial.
