Parthenium weed is a noxious invasive species that has negative effects on agriculture and also causes allergic reactions in humans. The goal of this study was to evaluate several management strategies for parthenium weed and assess the suitability of each control measure for farmers, and other stakeholders in Uganda. Field experiments were conducted in a completely randomized design, and the quadrat sampling method used to assess the effect of mulching, foliar application of table salt solution, hand pulling, slashing, hand hoeing, foliar herbicide application, and integrated weed management on parthenium plant populations. All tested weed management strategies except foliar herbicide application significantly (P0.05) reduced parthenium plant populations, with parthenium weed counts for treated plots reducing on subsequent data collection days. The experimental data showed that parthenium plant populations increased for the untreated plot overtime. The authors recommend that a combination of multiple weed control measures (integrated weed management) are utilized for effective management of parthenium weed in Uganda to reduce limitations that result when one management strategy is used singly. This study informs farmers, the general public, and researchers how to effectively control parthenium weed, contributing to reduction of the numerous negative effects of parthenium weed on human livelihoods.
Key words: Agriculture, invasive, management, noxious, parthenium weed, Uganda.
