Comparative Effect of Chemical Insecticide (Cypermethrin) and Lemmon Grass Extract in Growth of Maize

Abstract

The use of commercially available synthetic insecticides against insect pest in agriculture has led to their bioaccumulation, and contamination of the environment, causing increased resistance and reduction in soil biodiversity as well as poses considerable dangers for consumers. The control of these insect pests is also difficult because of their high reproductive capacity and adaptability in various climatic conditions. Therefore, growing attention has been given toward the development of alternate environmentally friendly insecticides that would aid an efficient pest management system and also prevent chronic exposures leading to diseases. One such strategy is, the use of lemon grass which is safe and have a widespread use due to their, insecticidal, and insect repellent activities. They are easily available, non-toxic, and safe for human health, in addition to having a pleasant aroma. In this study lemon grass extract was used as the Biocontrol agents for plant pests, while cypermethrin was used as the Chemical insecticide. Result showed that lemon grass extract offered protection to the maize seeds by scaring insects away, and maize seed treated with lemon grass extract performed better the other treatments both in germination and other morphological parameters such as plant height and leaf length. Maize farmers are therefore encouraged to use lemon grass extract for protection from pests and to increase yield.
