Abstract

The tomato pinworm, Tuta absoluta (Meyrick), fruit borer, Helicoverpa armigera (Hübner) and red spider mite, Tetranychus urticae (Koch) are destructive pests exerting a high crop loss in India. A field experiment was carried out to evaluate the effectiveness of different treatments at College of Agriculture, Vijayapura, UAS, Dharwad. The treatment Chlorantraniliprole 18.5% SC @ 0.15ml/l was recorded lowest pinworm larvae (1.76/plant), least number of live mines (1.50/plant), less fruit damage (2.02 per cent fruit damage) at fifth day. Similarly less number of fruit borer larvae (1.10/plant) and least fruit damage (2.06/plant) were observed in the same treatment. The treatment Spiromesifen 22.9 % SC recorded lowest number of red spider mite population (1.07 mites/sq inch) at third day. The combination treatment of chlorantraniliprole 18.5 % SC @ 0.15 ml/l followed by spiromesifen 22.9 % SC @ 0.5 ml/l was the best one to control pinworm, fruit borer and red spider mites on collective basis and which was also recorded highest yield (19.22 t/ha), Benefit-Cost ratio (2.70)

Conclusion

Based on the outcomes of the present investigation, it can be inferred that the combined chemical management approaches towards most destructive pests pinworm, fruit borer and red spider mite was achieved with different insecticides and acaricides with higher yield
