Experiment Title Evaluation of biopesticides against pod borers infesting green gram
Research Type Departmental Research
Experiment Background Pulses are grown in the semi-arid regions under a wide range of agro-climatic conditions of India. Among the pulses, mungbean or green gram, Vigna radiata (L.) Wilczek is the important pulse crop of India. Green gram is cultivated throughout the year in all the cropping seasons due to its short duration and suitability to crop rotation and crop mixtures. The low productivity in green gram may be attributed to factors like limited varietal improvement, soil moisture stress, pest infestation etc., among them; ravage of insect pests is the most important (Sandhya et al. 2015). Legume pod borer, Maruca vitrata and Helicoverpa armigera contributes to a major yield loss. It becomes a menace especially during the flowering and pod formation stages (Atachi and Djihou 1994; Yadav and Singh 2014). The larvae cause direct damage to flowers and pods, hence stands responsible for major yield loss in all the host crops. The grain yield losses due to legume pod borer are estimated from 10 to 80 per cent in various crops (Sharma 1998; Sambath Kumar et al. 2014). Though the synthetic pesticides are used to combat podborer, but their widespread use has created a variety of problems and has become a threat to human health. Further, the application of synthetic pesticides has contributed to the environmental pollution through air or as residues in food. Considering the importance of biopesticides, this research work will be proposed to know the effectiveness of various biopesticides against pod borers infesting green gram
