Management of tomato fruit borer by incorporating newer and biorational insecticides

Narendra Singh, SK Dotasara, Bhoopender Kherwa and Swaroop Singh

An attempt was made to evaluate nine newer and biorational insecticides against fruit borer, Helicoverpa armigera infesting Tomato at farm of Agricultural Research station, Swami Keshwanand Rajasthan Agricultural University, Bikaner, during the rabi season 2013-14. Among nine insecticides, indoxacarb 14.5 SC (0.01%) was found most effective against fruit borer followed by novaluron 10 EC (0.01%) and acephate 75 SP (0.037%). Bacillus thuringiensis 8L (0.012%) proved least effect followed by HaNPV (250 LE/ha) and quinalphos 25 EC (0.02%).The treatments of chlorantraniliprole 18.5 SC (0.02%), abamectin 5 SG (0.01%) and spinosad 2.5 SC (0.01%) ranked in middle order of their efficacy. All the insecticides significantly increased the yield of marketable fruits over control. The maximum yield (265.20 q ha-1) was recorded in indoxacarb followed by novaluan (262.85 q ha-1) and acephate (258.22 q ha-1). The minimum yield was recorded in B. thuringiensis (206.54 q ha-1) followed by HaNPV (213.24 q ha-1).
