Abstract

A controlled release granular formulation using the suSCon technology to continuously release carbosulfan into the soil for two years has given control of termites attacking new Eucalyptus plantations in Zimbabwe and South Africa. The product has also provided control of Hylobius bark weevils attacking new conifer forests in France. Use of non-persistent carbosulfan in this way offers an alternative to organochlorine insecticides about which there is international concern because of persistence and risk of accumulation in the environment. Three field trials with carbosulfan suSCon controlled release granules for control of termites during establishment of Eucalyptus plantations are being conducted in Brazil to assess the effectiveness over a two year period against termites species other than those occurring species attacking Eucalypts in Brazil belong to the genera Syntermes Heterotermes and Procornitermes. Carbosulfan controlled release granules at rates of 0.75 1.0 and 1.5g. a.i. per plant were applied either to the bottom of the planting hole or applied on the surface and lightly incorporated. The standard treatment for comparison aldrin at 2kg a.i. per ha and the carbosulfan CRG treatments significantly reduced MSD Tukey 5percent the seedlings killed by termites at 90 108 and 40 days after treatment in field trials 1 2 and 3 respectively. Tree mortality in the control plots of these trials was 13 3 24.4 and 17.8percent respectively. These trials show that suSCon 100 gram/kg carbosulfan controlled release granules are as effective as the standard aldrin against termites in Eucalyptus plantations in Brazil
