## A turning point for global agriculture

2026 has marked a critical inflection point for global agriculture, plunging producers into a level of uncertainty unprecedented in the last decade. Croplands no longer depend solely on an unstable rainfall regime: they now face a dual siege — an extraordinarily aggressive biological front and a paralyzing bureaucracy. This is not a phenomenon of isolated incidents. This decade's food crisis is no longer measured only in droughts, but in the speed at which pathogens are devouring the profitability of farming.

## Faces of drought and pests: the direct impact on the rural economy

To grasp the macroeconomic magnitude of this crisis, the land must be examined up close. In the state of Veracruz, communities such as San Pablo Coapan and Naolinco — historically prosperous due to their proximity to Xalapa — are experiencing an agricultural emergency of devastating proportions.

For smallholders, the threat has materialized as relentless pests. Local farmer Carlos Hernández Arellano describes how rust has mercilessly decimated coffee plantations, while the fall armyworm attacks the *milpa* from its earliest stages. His testimony illustrates a desperate reality: early infestation rapidly translates into total loss, forcing farmers to bear unaffordable mitigation costs amid the inaction of authorities such as Sedarpa.

And yet, along this same corridor toward Misantla, there are sparks of agronomic resilience. Farmer Germán Hernández has documented how his sunflower fields have managed to tolerate both biological pressure and severe low temperatures. This natural contrast not only offers hope to the region but also frames crop diversification as an imperative for survival.

## Anatomy of the pathogens: rust, worms and root diseases

The visible devastation on the leaves is only the surface of the problem; the real damage occurs at the cellular and root level. Rust, a parasitic fungus, spreads violently through wind-borne spores, tinting the foliage with a characteristic orange dust that suffocates the photosynthetic capacity of coffee.

In turn, the destructive mechanics of the fall armyworm (*Spodoptera frugiperda*) are surgical. The larva does not merely chew the outer leaf; it pierces tender tissue to lodge directly in the vital center of the maize plant, ensuring the destruction of the crop.

On top of this aerial offensive comes an invisible, lethal threat below ground. Data from agronomic technical forums reveal that root damage is accelerating premature death of the *milpa*. Soil pathogens such as those of the genus *Pythium* attack the root system directly — the "mouth" through which the plant feeds — strangling its ability to absorb water and nutrients in an environment already battered by water stress.

## The climate factor: the catalyst of agricultural mutation

Local suffering is not a coincidence; it is the symptom of an irreversible environmental macro-trend. Recent research from the University of Guadalajara (UdeG) shows that the sustained alteration of climate patterns is acting as a steroid for pathogens. Rising baseline temperatures and the drastic reduction of seasonal humidity are accelerating metabolism and shortening the reproductive cycles of both insects and fungi.
**UdeG research:** Climate stress breaks the innate defenses of agricultural ecosystems, causing endemic pests — once controlled naturally — to adopt epidemic, destructive behaviors.
Vulnerability is even greater in cropping areas under pressure from urban expansion, such as the Valle de Tesistán in Zapopan, where climate change combined with real-estate pressure facilitates the proliferation of pathologies such as powdery mildew in peri-urban nurseries.

## The bureaucratic dead end: phytosanitaries and laws in collision

While biology accelerates, the institutional response stalls. European farmland illustrates this regulatory collision perfectly, with the Region of Murcia and Campo de Cartagena turned into ground zero for bureaucratic paralysis. The agricultural sector has filed formal complaints to the Ministry of Agriculture, Fisheries and Food (MAPA), pointing out that the EU "Farm to Fork" strategy is ineffective and suffocating in times of phytosanitary emergency.
**Regulatory blockage:** The urgency lies in the administrative inability to activate **Article 53 of Regulation (EC) No 1107/2009**, which allows exceptional temporary authorizations (e.g. spirotetramat 10%). This blockage leaves Spanish producers at a severe competitive disadvantage versus their European neighbors.
The consequences of this inaction are quantifiable: traditional pests such as the aphid now threaten more than 6,000 hectares in eastern Almería and the Valencian Community without effective control.

## The exotic greenhouse threat

The bureaucratic impact takes on a catastrophic dimension when faced with imported pathogens, such as *Thrips parvispinus*. This exotic insect has ceased to be a mere taxonomic curiosity and has become a massive destroyer of commercial value in protected environments.

Its biology is perfectly tuned for economic devastation. Under greenhouse conditions — 24 °C with 65 % humidity — it completes its accelerated reproductive cycle in just **14 days**. This explosive behavior translates into a direct, massive attack on 1,248 hectares of protected pepper.

The risk is absolute: the pest threatens to wipe out a harvest estimated at 150,000 tonnes, representing a financial impact of more than **€110 million**.

## Resilience and future: the transition toward sustainable plant health

Faced with the inefficiency of traditional government bailouts and the strict restrictions on agrochemicals, the sector has no choice but to embrace scientific innovation. The way out of this crisis does not lie in returning to past practices, but in an accelerated transition toward genuinely sustainable, systemic plant health.

**A return to biodiversity:** University researchers strongly advocate abandoning monoculture. Reviving polyculture and returning to the traditional *milpa* system act as natural biological barriers, diluting the vulnerabilities that pests exploit.

**Institutional prevention:** Entities such as the Agency for Agri-food Health, Safety and Quality (ASICA) in Jalisco have demonstrated that aggressive preventive campaigns and proper management of agricultural environments make the difference between survival and bankruptcy.

21st-century agriculture has ceased to be a brute-force war with chemicals to become an exercise in high biological diplomacy and regulatory agility. The producer who manages to keep the harvest will not simply be the one who plants the seed, but the one backed by an unshakable alliance among scientific rigor, integrated pest management and truly adaptive State policies.
## Technical glossary

Thrips parvispinus

Invasive exotic thrips; ~14-day reproductive cycle under greenhouse conditions (24 °C, 65 % RH).

Spirotetramat

Two-way systemic insecticide regulated under Regulation (EC) No 1107/2009.

Powdery mildew

Fungal disease (Erysiphales) producing a whitish dust on leaves; common in peri-urban nurseries.

Polyculture

Agronomic strategy combining several species in the same plot to dilute pest vulnerabilities.

Integrated Pest Management (IPM)

Framework integrating biological, cultural, physical and chemical control to minimize agrochemical use.
