Control de Oxalis latifolia: Revisión y propuestas para su mejoramiento

Abstract

A. Royo-Esnal, and M.L. López. 2008. Control of Oxalis latifolia: a review and proposals for its improvement. Cien. Inv. Agr. 35(2):121-136.Oxalis latifolia is a weed with a tropical, temperate and mediterranean distribution. It invades orchards, plant nurseries, gardens and corn fi elds. Although some mechanical and cultural methods and some herbicides may achieve excellent controls over this weed, their application is usually diffi cult and expensive. However, some specifi c characteristics in its annual life cycle make O. latifolia quite vulnerable. That is why the combinations of adequate control methods, such as ploughs, delay of sowing and mulches together with residual or foliar herbicides, are necessary to seek for each crop and climate, always taking in care the weed's biological particularities. Finally, new research lines that are less known in order to make the most of O. latifolia, such as its allelopathic characteristics or its use as a cover plant, are pointed out.

Euro+Med-Checklist Notulae, 13

“…Now it has become a transcontinental weed of crop fields, orchards, gardens, nurseries etc. (Lourteig 2000;Royo-Esnal & López 2008;CABI 2020) and is included as an invasive species in the Global Compendium of Weeds (Randall 2017), the Global Invasive Species Database (GISD 2021b) and the Invasive Species Compendium (CABI 2020). In Europe, this species has been recorded in at least 15 countries at different stages of naturalization (Henning & Raab-Straube 2016+a;Randall 2017).…”

Assessing the Potential Distribution of Oxalis latifolia, a Rapidly Spreading Weed, in East Asia under Global Climate Change

“…It was introduced to Africa, Asia, and Australasia before 1950 for ornamental purposes [ 1 , 2 ]. It is distributed throughout tropical, Mediterranean, and temperate climates [ 3 ]. It is a low-growing plant with three broad leaflets on long petioles and reproduces both vegetatively by means of bulbs and sexually by means of seeds [ 4 , 5 ].…”

“…O. latifolia is referred to as a noxious and invasive weed as it has caused losses of 30 different types of crops, including rice, tea, potato, and apple, in 37 countries [ 3 , 6 , 7 ]. Its uncontrolled growth has resulted in a 56% maize reduction in India [ 8 ].…”

“…The distribution and invasiveness of plants are strongly influenced by climatic components, including temperature, precipitation, and atmospheric carbon dioxide [ 10 ]. Temperature plays important roles in the activation of O. latifolia bulbs [ 3 ]. The annual cycle begins when the bulbs are activated, occurring at temperatures above 15 °C in soil, and dormancy can last for more than 1 year [ 6 ].…”

“…In East Asia, O. latifolia currently occurs in China and Chinese Taipei, with predictions of introduction from South Asia (e.g., India). It is well established in disturbed areas and is rapidly expanding into agriculture and pastures, resulting in productivity loss in such areas [ 3 ]. Future climate change is likely to favor the habitat expansion of O. latifolia , extending to other countries in East Asia.…”
