Is Aphid Management Sustainable in Desert Head Lettuce?

Abstract

New restrictions on insecticides for aphid control presents new challenges for lettuce growers. Dimethoate is soon to be unavailable and the future status of other conventional aphicides is uncertain. However, a number of new active ingredients will soon be available that offer lettuce growers valuable alternatives for aphid management in lettuce. The present dilemma and potential for implementing new chemistries into lettuce IPM programs is discussed in this report.
