The Ministry of Agriculture and Rural Development of Mexico has declared four municipalities in Sonora pest-free for potato cultivation. The declaration, published in the Official Gazette of the Federation, aims to regulate the entry of potato seed-tuber to prevent the introduction of three pests that could lead to production losses. The recognition is valid for two years, during which the National Service of Health, Safety and Agrifood Quality will monitor the area. This measure is expected to increase the competitiveness of the potato crop in the region.
