Argentina: Bacterial black spot disease detected in mangoes

Published Mar 29, 2023

Tridge summary

Argentina is experiencing a surge in mango production, particularly in the province of Formosa, but the expansion is threatened by the bacterial black spot disease, caused by Xanthomonas spp. The disease has been identified in multiple mango varieties, including the popular Tommy Atkins, leading to significant losses and reducing the commercial quality of the fruits. In response, INTA recommends management practices to prevent the disease's spread, such as avoiding humidity, cleaning agricultural machinery, using disinfectants, and planting disease-free seedlings. Additionally, the use of windbreaks and internal pruning is suggested to reduce humidity and prevent bacterial spread. This concerning discovery does not deter the growth in mango cultivation, with over 400 hectares in Formosa, as farmers find it a profitable activity between banana harvests. Despite the challenges, INTA is conducting trials to gather technical information for improved mango production.

Mango production in Argentina is booming. The agroecological characteristics of the NEA allow the development of the production of this fruit and that the cultivation extends to various areas of the province of Formosa. From the Research and Technological Development Area for Family Agriculture (IPAF) in the NEA region of INTA, a research team detected the presence of bacterial black spot in a batch of mangoes from the unit. This disease is considered the most important and limiting of the cultivation of this fruit. Pilar Ortega y Villasana – IPAF NEA researcher – explained that the bacteriosis detected in mango lots is caused by Xanthomonas spp.: “We are facing a very severe attack on the Tommy Atkins mango variety. After sending the samples to the Plant Health Laboratory of the INTA Bella Vista Agricultural Experiment Station in Corrientes, who confirmed that the bacteriosis was caused by Xanthomonas spp. At the same time, pathogenicity tests are being carried out in said ...
