Abstract:
Bacillus thuringiensis (Berliner) has been under extensive use as a biopesticide for the last 55 years in many parts of the world, contributing 90% of the total commercial biopesticides formulations. It is being utilized as a natural regulating agent for different lepidopteran pests of tea. Recent studies revealed that commercial formulations of Bt were as effective as chemical pesticides. With the advent of genetic engineering, the insecticidalgene of Bf has been successfully isolated and cloned into many commercial crops. This review paper critically discusses the scope of using Bt and Bt transgenics for the management of tea pests.
