Description

Aphid populations for the growing seasons of 1970, 1971, and 197 2 were variable. It is possible, however, to rate the efficacy of the various insecticides tested in controlling potato-infesting aphids in northeastern Maine. Soil applications of aldicarb and DS 15,647 and foliar application of acephate were the most effective materials tested. The insecticides phosmet (foliar) and phoxim (soil) did not provide much protection against potato-infesting aphids in these tests. Bayer 77,049, parathion, Penick SBP 1382, Sandoz-Wander 52,139 and Uniroyal 840 did not provide effective control of potato-infesting aphids at the rates used in these tests. All other insecticides tested adequately controlled aphid populations, but their effects on the spread of leaf roll varied. Some of the materials tested were experimental materials and not all are available for commercial use.
