Impact of integrated pest management strategies for shoot and fruit borer in brinjal

Sumathi E, Manimaran R and Ilamaran M

Shoot and fruit borer, Leucinodes orbonalis Guen is the major pest of brinjal and cause heavy economic loss to brinjal growers. To avoid ill effects of insecticides, Integrated Pest Management strategies had been promoted through front line demonstrations in 10 farmers field in Tiruvallur District during 2014 -15 and 2015-16. IPM strategies include clipping and disposal of infested shoots, removal of fruits with boreholes, installation of pheromone traps @ 12/ha, release of Trichogramma chilonis @ 8 cc/ha for 4 times at weekly interval, spraying of Bacillus thurinjiensis @ 1 kg/ha and Flubendiamide 20 WDG 7.5 g /10 lit. The mean of the parameters in 10 demonstrations during 2014-15 and 2015-16 revealed that shoot and fruit borer damage at vegetative phase as shoot damage was 13.6 per cent in IPM field and 19.6 in farmers practice (only insecticides). Fruit damage was found to be low 15.9 per cent in IPM field while in farmers practice it was 25.0 per cent. Fruit yield was found to be high, 32.8 t/ha in IPM field when compared to farmers practice (Non IPM). Benefit Cost Ratio also was found to be high (4.05) in IPM field where as the ratio is low (3.1) in farmers practice.
