- Abstract
Brinjal shoot and fruit borer Leucinodes orbonalis Guenee is an important pest. Two field experiments conducted at the Tamil Nadu Agricultural University, Coimbatore during 2016 - 2017 using brinjal variety CO2 evaluated carbosulfan 25EC against this, and toxicity to natural enemies along with phytotoxicity, if any was analysed. The results revealed that based on shoot damage, carbosulfan 25EC @375 g a.i. ha-1 was similar to its dose @312.5 g a.i. ha-1 and 250 g a.i. ha-1. Emamectin benzoate 5SG at 10 g a.i. ha-1, lambda cyhalothrin 5EC @ 15 g a.i. ha-1, fenpropathrin 30EC @ 100 g a.i. ha-1 followed next with similar efficacy. Pooled data of fruit damage also revealed the efficacy of carbosulfan 25EC at 375 and 312.5 g a.i. ha-1 at par with each other, resulting in maximum yield of 18.67 and 17.37 t. ha-1, respectively. Carbosulfan 25EC @ 375 g a.i ha-1 was observed with 1.85 coccinellids/ plant followed by emamectin benzoate 5SG at 10 g a.i. ha-1, fenpropathrin 30EC @ 100 g a.i. ha-1, lambda cyhalothrin 5EC @ 15 g a.i. ha-1 and carbosulfan 25EC @ 250 g a.i. ha-1. Carbosulfan 25EC at 312.5 g a.i ha-1 and 625 g a.i ha-1 did not show any phytotoxic effects.
