Laboratory and field evaluation of seven insecticides for control of the alfalfa stem nematode, Ditylenchus dipsaci (Kühn, 1857) Filipjev, 1936

Abstract

The production of lucerne, which is important for the expansion of the dairy industry in Iran is seriously threatened by stem nematode attack (Abivardi and Sharafeh, 1973). Control of stem nematode attack by treating plants with various organic phosphorus compounds has proved moderately successful (Bergeson, 1955; Feder, 1952; Gostick, 1963; Griffin, 1967; Henderson and Williams, 1955; Pitcher, 1959; Oliff et al., 1969). More recently developed compounds like thionazin, aldicarb and trichloronate were equally or more effective. To investigate whether insect and nematode control could be obtained by the same treatment, the effect of several organic phosphorus compounds on attack of lucerne by stem nematodes was investigated in laboratory and field experiments.
