abstract
Among the vegetable crops grown in India, brinjal occupies largest area and plays a vital role in total vegetable production. Brinjal is more vulnerable to the damage caused by shoot and fruit borer, Leucinodes orbonalis Guenee which acts as a major pest and cause heavy economic loss to the farmers. To avoid ill effects of insecticides, bio-intensive integrated pest management strategies have been promoted through front line demonstrations in 10 farmers field at Thirupathisaram, Kanyakumari district, Tamil Nadu, India. The results of ten demonstrations conducted during the year 2015-16 and 2016-17 revealed that shoot and fruit borer damage at vegetative phase was 2.98 per cent in recommended practice and 19.35 in farmers practice. Fruit damage was found to be low in recommended practice (7.71 per cent) while in farmers practice, it was 36.53 per cent. Fruit yield was found to be high (30.45/ha) in IPM field when compared to farmers practice (23.24 t/ha). Benefit Cost Ratio also was found to be high (3.74) in IPM field where as the ratio is low (2.10) in farmers practice.
