dc.description.abstract Cigarette tobacco production is done by the registered farmers of Ceylon Tobacco Company for a pre-trade agreement while other types are grown purely on freelance basis and hence cigarette tobacco production has a better accountability. It is a great matter of concern that, tobacco plant is susceptible for cutworm damage during its life cycle eventually making inconsistent production. It causes a considerable damage to the tobacco plant particularly in the vegetative growth. The cutworm damage is more severe in the field level and in many cases it is present in the nursery level too. The Ceylon Tobacco Company has clearly discovered the demerits of the prevailing pest and chemical control has been playing a leading role for a long period of time as it has become more successful in its efficacies. The company commonly uses Chlorpyrifos 40 EC, a broad spectrum contact insecticide, which belongs to the chemical group of Organophosphate. Direct application of organophosphate insecticides including Chlorpyrifos is toxic and causes environmental pollution. In the environment, the organophosphate insecticide residues and the degraded ingredients pollute the soil, water, air and food. These compounds harm not only non beneficial insects but also beneficial insects, beneficial soil organisms and other animals including human beings. Therefore, usage of Chlorpyrifos is supposed to be phased out from the tobacco cultivations in the island wide. The objective of this study was to find a possible alternative to Chlorpyrifos to reduce environmental toxicity. en_US
