Insight of botanical based biopesticides against economically important pest

Abstract

This paper reviews the plant based biopesticidal product and its activity against the economically important pests. Other than identified botanicals like neem, neem gold etc., about 211 plant species were explained to have different types of pest management properties in laboratory conditions against defoliator pests. The term biopesticide embraced a wide diversity of both chemical and microbial active ingredients. Conventional insecticides possess inherent toxicities that endanger the health of the farm operators, consumers and the environment. Negative effects on human health led to a resurgence in interest in botanical insecticides because of their minimal costs and fewer ecological side effects. Botanicals have advantages over broad-spectrum conventional pesticides. They affect only target pest and closely related organisms, are effective in very small quantities, decomposed quickly and provide the residue free food and a safe environment to live. When incorporated into integrated pest management programs, botanical pesticides can greatly decrease the use of conventional pesticides or can be used in rotation or in combination with other insecticides, potentially lessening the overall quantities applied and possibly mitigating or delaying the development of resistance in pest populations
