Efficacy Of Botanicals Against Mulberry Whitefly <i>Dialeuropora Decempunctata</i> (Quaintance and Baker) And Their Safety To Natural Enemies

Abstract

In the evaluation of efficacy of seven biopesticides, two foliar sprays done at fifteen days interval were effective in reducing whitefly Dialeuropora decempunctata (Quintance and Baker) incidence in mulberry. Neem oil (3%) was the most effective (71.10% reduction over control) followed by pongamia oil (3%) and Torpedo (plant extract of Sophora and Stemona sp.-1ml/l) by 65.14% and 59.61%, respectively. Tobacco decoction (5%), ginger rhizome extract (15%) and chilli-garlic extract were the least effective. All the evaluated botanicals were safe to natural enemies observed on mulberry. Chilli-garlic extract and ginger rhizome extract were the safest against coccinellids and spiders, respectively.
