The agricultural sector in the Region of Murcia, Spain, is facing a growing crisis dubbed a “horticultural covid” by local officials, as increasing pest infestations and stricter European regulations combine to disrupt exports and lead to product rejections from supermarket chains. Growers are struggling with a lack of effective crop protection tools, exacerbated by climate change and a regulatory landscape that hasn’t kept pace with emerging threats. The situation is prompting urgent calls for intervention from both regional and national authorities.
The core of the problem lies in the diminishing availability of certain plant protection products due to increasingly stringent European regulations aimed at reducing the environmental impact of chemicals. This reduction hasn’t been matched by the development and approval of equally effective biological or naturally-based alternatives, leaving farmers vulnerable to escalating pest pressures. Combined with increasingly erratic weather patterns – prolonged droughts followed by intense rainfall – the region is experiencing a surge in pests like aphids and thrips, impacting crop quality and yields. Decree n.º 208/2014, established measures for the sustainable use of plant protection products in the Region of Murcia, but the current situation highlights the demand for updated strategies.
Export Rejections and Economic Losses
The consequences are already being felt by exporters, who are facing economic claims and returns of produce – including lettuce and broccoli – from supermarket chains due to the presence of insects within the leaves. These infestations occur during the early stages of cultivation, making detection difficult. José Miguel Marín, president of COAG Murcia, warned that the problem, currently affecting horticultural crops, is expected to spread to citrus fruits within a month. COAG, a farmers’ organization, has convened meetings with regional agricultural authorities, irrigators, producers, and plant protection companies to coordinate a response to this “health emergency.”
The organization is advocating for the Spanish Ministry of Agriculture to approve exceptional authorizations for the use of specific plant protection products, mirroring measures already adopted in Italy, Portugal, and France. They are likewise urging the regional government to compile scientific reports to support the appropriate use of chemical compounds although minimizing their impact on biodiversity and soil health, and ensuring food safety. The use of previously prohibited products could be authorized for a period of 120 days, with potential for extension if the urgent situation persists.
Seeking Government Intervention
COAG, along with exporter associations (Proexport) and cooperatives (Fecoam), has requested a meeting with the Government Delegate, Francisco Lucas, to mediate with the Ministry of Agriculture and present evidence of the “critical situation” and the resulting “million-euro losses” to the sector. Regional Agriculture Counselor Sara Rubira described the situation as a “horticultural covid,” emphasizing the need for swift responses from both regional and national governments. Rubira also criticized the Ministry for not addressing Murcia’s requests for several products and questioned why the insecticide Movento has been exceptionally authorized in six other European countries but not in Spain. Decree 208/2014 outlines the framework for sustainable plant protection, but the current crisis demonstrates the need for flexibility and responsiveness.
The regional government, along with the Valencian Community and Andalusia, has sent a letter to Minister Luis Planas requesting an urgent meeting to discuss the situation and authorize the necessary plant protection tools to ensure sector profitability. The letter expresses concern over additional requirements imposed by European supermarkets regarding the use of active substances in plant protection products, and the increasing consumer demand for produce free from pests like aphids and thrips, leading to rejections at destination markets.
Biological Controls and Increasing Pest Populations
While the sector is actively pursuing biological control methods and less aggressive pesticides, these efforts are proving insufficient to combat the year-on-year increase in pest populations. Over the past two campaigns, populations of thrips, aphids, scale insects, and whiteflies have risen across all crops, causing significant economic losses and even total crop failures in some cases, such as table grapes and citrus fruits. The official decree highlights the importance of a comprehensive approach to plant health management.
A meeting of the Regional Plant Health Table is scheduled to address the issue, and the Ministry of Agriculture is expected to consider the concerns raised by the affected regions. The situation underscores the complex interplay between environmental regulations, climate change, and agricultural production, and the urgent need for collaborative solutions to ensure the sustainability of the horticultural sector in Murcia and beyond.
Looking ahead, the outcome of the meeting with Minister Planas and the potential authorization of exceptional measures will be critical in determining the short-term fate of the region’s crops. The long-term solution will require continued investment in research and development of sustainable pest control methods, as well as a more flexible and responsive regulatory framework that can adapt to the evolving challenges posed by climate change and emerging pest threats.
