Bio-pesticidal potential of the crude extract of Andrographis paniculata [(Burm. F.) Wall ex. Nees] in the agricultural field: A review

Kalmegh [Andrographis paniculata (Burm. F.) Wall ex. Nees] is one of the significant medicinal plants which possess active ingredients of therapeutic potential, widely used in the treatment of anti-inflammatory, anti-bacterial, anti-oxidant, hepatoprotective, etc. The plant is widely used in the Ayurvedic and homeopathic systems of medicine. In spite of this, kalmegh exhibits insecticidal and repellent properties against pests and insects of important medicinal significance and can be used as a promising bio-insecticide/pesticide. All the useful collective information and the database of the review are generated from the previously published articles using Web of Sciences, PubMed, Google Scholar, and other web searches. It possesses biopesticidal/insecticidal properties such as suppressing feeding activity, anti-oviposition activity, and weedicide of Plutella xylostella, Spilaractia obliqua, Callosobruchus chinesis L., Nephotettix cincticeps, Helicoverpa armigera, Parthenium hysterophorus, etc. Thus this review will provide some positive aspects towards the research for exploration and further studies in the future. This review outlines the summary of factual records of previous research concerning its ethnobotany, phytoconstituents, and bio-insecticidal/pesticidal potential of the crop. However, in the research sector, Andrographis paniculata's prospects will be on an upswing, the demand of the crop burgeoning in the industries, and eventually, farmers also reaping its benefits.
