Abstract

Comparison of non-persistent insecticides in controlled release granules with a persistent organochlorine insecticide for the control of termites in young Eucalyptus plantations in Zimbabwe.

Abstract

Granular formulations of 3 insecticides, carbosulfan, carbofuran and chlorpyrifos, applied to the potting soil, were tested in 5 field trials in 1985-88 as alternatives to aldrin for the control of fungus-growing termites (Macrotermes falciger, M. natalensis, M. michaelseni, Pseudacanthotermes militaris, Ancistrotermes latinotus, Odontotermes spp. and Microtermes spp.) in plantations of E. grandis and E. camaldulensis. Control comparable to that offered by aldrin was achieved with carbosulfan at doses in excess of 0.29 g a.i. per plant. No systemic control of termites attacking the trees above the treated soil was evident. Chlorpyrifos and carbofuran were not regarded as suitable alternatives to aldrin due to severe phytotoxicity at the doses required to control termites.
