Abstract

CUEVAS-CASTILLEJA, Jessica et al. Perspectives of integrated pest management in CDMX urban agriculture and impacts of SARS-CoV-2 health emergency. Rev. mex. fitopatol [online]. 2021, vol.39, n.spe, pp.328-350.  Epub Nov 30, 2022. ISSN 2007-8080.  https://doi.org/10.18781/r.mex.fit.2021-6.

The objective of this work was to determine the impact of COVID-19 on productive activities of farmers and extensionist, and the level of application of Integrated Pest Management (IPM) in urban agriculture in Xochimilco, Milpa Alta, Tláhuac, Tlalpan, Magdalena Contreras and Cuajimalpa at Mexico City, a metropolitan area with a high SARS-CoV-2 positive cases. In 2020, a digital survey was applied to a total of 108 farmers and extensionists during the first COVID-19 epidemic wave. The sanitary emergency reduced the continuity of the extension service. However, this was carried out with digital technologies including photographs submitted by WhatsApp for pest diagnosis purposes. During the maximum COVID-19 peak (July, 2020), only 14% of farmers declined to sowing the summer fall season 2020. The majority established corn and, to a lesser extent, vegetables in mixed topologies. However, the activity of agricultural workers was reduced to 50%. Up to 75% of farmers reported losses of 20% derived from the epidemic. The major pest control strategy was mechanical, mainly for preventive purposes (67%) followed by chemical control (52%), biological at both preventive (8%) and curative (25%) levels, and the combination of more than one strategy in less than 10%. The data indicate an intuitive understanding of the IPM benefit, although the farmer is unaware of its principles. Faced with the growing demand for fresh, quality and safe food as a COVID-19 preventive strategy, urban agriculture has great development prospects by supplying local markets without transport problems caused by regional and global contingencies such as that caused by SARS-CoV-2. However, public and institutional policies of great vision are required. This work recognizes the work of farmers, as well as extensionists in favor of food security.
