Abstract
Of 11 insecticides tested, nine were as effective as dimethoate for control of the pea aphid, Acyrthosiphon pisum (Harris), in alfalfa. None, including the systemic insecticides, provided adequate protection in growing alfalfa at 7 days after treatment. The environmental impact of these materials could be reduced if the lowest effective rates were used for control because repeat applications may be required. Because pirimicarb at 0.28 kg AI/ha had a reduced effect on Chrysopa oculata (Say), a predator of the pea aphid, it would be preferred to dimethoate for control of this aphid.This publication has 5 references indexed in Scilit:
