Bioefficacy of crude polyherbal formulations against hoppers (Insecta: Hemiptera) of rice

Abstract

Bio-efficacy of two crude polyherbal formulations against Nephotettix virescens-the Green Leafhopper (GLH) and Sogatella furcifera, the White-backed plant hopper (WBPH), major sucking insect pests of paddy was carried out at farmer's field of North Gujarat Zone (GJ-4), Gandhinagar, Gujarat during Kharif 2018. The aqueous and oil-based crude formulations were tested at two different concentrations each, in comparison with chemical, botanical and untreated control. Both the crude formulations were effective in the management of green leafhopper and white backed plant hopper in a dose-dependent manner, however, the aqueous formulation was more efficacious as compared to the oil-based formulation. These herbal formulations are an eco-friendly, cost-effective and safe alternative to chemical control measures for the management of paddy pests and can easily be incorporated in the integrated pest management (IPM) programs for the control of sucking pests in Paddy.
