Efficacy of different pesticides against major pests infesting tomato (Solanum lycopersicum L.)

Abstract

In order to examine the efficacy of different pesticides against major insects of tomato, a field study was determined at the Central Experimental Station, Wakawali, during rabi, 2018-2019. Four important pests were found infesting tomato including whitefly, aphid, leaf miner and fruit borer. The results revealed that Beauveria bassiana @ 5 ml lit-1 was the best treatment which was recorded minimum (3.28) mean whitefly population per three leaves followed by Azadirachtin 1% EC @ 0.002 per cent which recorded (3.32). For aphid, treatment Lecanicillium lecanii @ 5ml lit-1 was the best treatment which was recorded minimum (1.47) mean population per three leaves followed by Beauveria bassiana @ 5ml lit-1 which recorded (1.67) aphids per three leaves. Emamectin benzoate 05 SG @ 0.002 per cent was found most effective treatment for leaf miner and fruit borer which recorded lowest per cent leaf miner infestation (11.71%) and 13.10 per cent and 11.81 per cent on number and weight basis, respectively. Also Azadirachtin 1% EC @ 0.002 per cent was noticed effective against fruit borer damage which recorded 15.40 per cent on number and 13.86 per cent on weight basis.
