Deepa Srivastava, Swati Shahi and Rajnish Kumar

Identification of species with allelopathic potential has been a target of researches aiming to use them to control crop weeds. Ipomoea cairica is considered a weed with allelopathic potential, which has already been reported. The goal of this study was to evaluate the allelopathic properties of leaf extracts from Ipomoea cairica on the early development of noxious weed Parthenium hysterophorusin Gorakhpur. We tested the effects of leaf extracts, in three concentrations, on the early development of the species. The extracts negatively affected the early development and the morphology of the target species, and the phytotoxic effect was higher as the concentration of the extracts increased.
