This chapter highlights a survey of vegetable-producing areas to determine the occurrence, distribution and importance of Parthenium hysterophorus in Trinidad. The weed can significantly reduce crop yields and quality due to its aggressive growth habit, competitiveness and allelopathic interference. Due to its invasive capacity and allelopathic properties, Parthenium hysterophorus has the potential to disrupt the natural ecosystem and threaten the biodiversity. It is a difficult weed to manage, and a wide variety of methods, starting with prevention and containment, is necessary to reduce the incidence and spread of this weed. An integrated approach using cultural, physical, chemical and biological techniques is necessary to be successful. Focus is made on specific herbicides currently being used to manage this weed in vegetables. Despite the negative impact of this weed on the biodiversity, this chapter also explores the potential of the beneficial properties of Parthenium hysterophorous as a mechanism of management.
