Management of Horse Purslane (Trianthema portulacastrum L.): An Overview

Vikas Kumar and Kamal Rai Aneja    

Abstract: Trianthema portulacastrum L. (Horse purslane) is an annual broadleaf troublesome weed of tropical and subtropical areas throughout the world. In India, it has been observed as a problematic weed in many states. Remarkable biological and ecological behavior of this weed has enabled its easy and rapid spread and naturalization in a wide range of habitats. Various pre and post-emergence herbicides are used for controlling this weed. With increasing global concern about pesticide residues in the biosphere and public demand for pesticide free-food, alternative pesticides, such as bioherbicides are becoming important. Presently, there are over 17 mycoherbicides against different weeds, which are commercially being used in the developed countries. Of these, 8 are registered in the USA, 4 in Canada, 2 in South Africa and 1 each in Netherland, Japan and China. A total of 9 fungal pathogens have been reported on this weed around the globe. Of these, Gibbago trianthemae has the potential to be developed as a mycoherbicide of horse purslane in the USA and India. In this study, attempts have been made to present distribution, menace and management of horse purslane, a notorious agricultural weed by mechanical, chemical and bioherbicidal means.
