ABSTRACT

 

Six biorationals viz. Beauveria bassiana (20 g/L), Neem oil (5 ml/L), Ginger rhizome extract (5%), Garlic bulb extract (2%), Lantana camara extract (5%) and Tobbaco leaf extract (5%) were evaluated against lettuce aphids, Nasonovia ribisnigri. The study was conducted in Random Block Design with seven treatments having three replications each. In the six months study period, our study reported the highest aphid count reduction in plots treated with Neem oil and B. bassiana with a per cent reduction of 95% and 93.60% respectively.

Keywords    Lettuce, biorationals, Aphids, eco friendly.
