A Review Study on Toxic Weed Plants in Jaunpur Region, UP

Abstract

Intense farming methods, rich alluvial soils, and a tropical monsoon environment that promotes the growth of a variety of weed flora are characteristics of the Jaunpur region in eastern Uttar Pradesh. Among these, a number of weed species have harmful characteristics that negatively impact human health, livestock health, and agricultural output. The identification, distribution, toxicity, and ecological effects of the most toxic weeds in the Jaunpur area are the main topics of this review. Argemone mexicana, Datura stramonium, Euphorbia hirta, Parthenium hysterophorus, and Calotropis gigantea are notable species. Through allelopathy, these weeds create toxic secondary metabolites like terpenoids, glycosides, and alkaloids that induce poisoning, allergic reactions, and crop growth suppression.The study emphasizes how human disturbances and a lack of efficient management techniques are causing them to spread more widely. To reduce their negative consequences, integrated weed management techniques—such as biological control, mechanical removal, and awareness campaigns—are crucial.
