Late-Season Citrus Protection in Europe
A Combined Hail Net + Rain Shelter Solution to Safeguard the Final Line of Defence for Your Annual Harvest
From February to March, citrus fruits in Europe—particularly blood oranges and pomelos—enter their final stage of ripening. This is the last window for sugar accumulation and quality formation, and also the critical period for harvesting, market supply and export fulfilment.
For the European citrus industry, led by Spain and Italy, the weather conditions and orchard protection measures during this final month can directly determine whether a season’s income is fully secured or significantly reduced.
In early 2026, however, European production regions are facing a series of extreme weather challenges.
According to the latest Northern Hemisphere citrus forecast from the World Citrus Organisation (WCO), total citrus production for the 2025–2026 season is expected to reach 27.397 million tonnes, representing a decline of 1.51% compared with last season and 5.13% below the four-year average.
Among major producers:
- Spain’s citrus production is forecast to fall by 9.72% to 5.59 million tonnes
- Italy’s production is expected to decline by 6.12% to around 3 million tonnes
Against a backdrop of reduced supply, high-quality fruit will become increasingly scarce. Citrus with smooth skin, no blemishes, uniform colour and optimal sweetness—classified as “Extra Class” fruit—will command higher premiums in export markets.
In such a season, those who succeed in protecting their crop until harvest will ultimately capture the greatest value.
Key Challenges：Rain, Hail and Disease
Spain: Valencia and Andalusia
Spain is Europe’s largest citrus producer, with Valencia and Andalusia forming the backbone of European citrus exports. However, the spring climate in February and March presents significant challenges during the final ripening stage.
Major risks include:
Heavy rainfall causing fruit splitting
Pomelos have relatively thin skins and high water content. When heavy rainfall occurs close to maturity, fruit may rapidly absorb water and swell, leading to fruit splitting rates exceeding 30%.
Hail damage leading to surface scars
Hailstones can directly strike the fruit surface, leaving permanent dents or scars and downgrading fruit from Class I to non-marketable grades.
High humidity triggering fungal diseases
After heavy rain, orchard humidity rises rapidly, creating favourable conditions for fungal diseases such as anthracnose and black rot.
According to global market reports on orchard protection systems, orchards represent the largest application sector for hail nets, accounting for more than 50% of total demand, reflecting the growing importance of protective infrastructure in fruit production.
Italy: Sicily
Italy is Europe’s second-largest citrus producer, and Sicily is globally renowned for its blood oranges. The region faces similar challenges during the late ripening period.
Key risks include:
Frequent convective weather events
Alternating heavy rainfall and hailstorms can disrupt harvesting schedules and impact export contract fulfilment, particularly as European citrus exports to Northern Europe and the Middle East, where strict visual quality standards apply.
Dust contamination and residue concerns
Open-field orchards without protective structures are more susceptible to dust contamination, which can reduce the visual quality of fruit and make it harder to meet the requirements of premium export markets.
A Common Challenge Across Europe
During the late ripening stage, citrus fruit typically has thin skin and high juice content, making it highly sensitive to sudden climatic fluctuations.
In orchards lacking adequate protection, loss rates can exceed 25%. In practical terms, this means that one quarter of a year’s harvest may be lost before reaching the market.
A Combined Hail Net + Rain Shelter Protection System
To address the practical challenges faced by citrus growers in Spain and Italy, we propose a dual-protection solution designed to minimise losses while safeguarding fruit quality.
Core System: Hail Nets + Rain Shelters
| Protection System | Primary Function | Technical Advantages |
|---|---|---|
| Hail Net | Protects fruit from hail damage | High-tensile PE material with optimised light transmission for photosynthesis |
| Rain Shelter | Prevents rain exposure and reduces humidity | Arch structure suited to orchard layouts with efficient drainage |
Hail Nets: A Protective Shield for Fruit Surfaces
Material performance
The system uses high-density polyethylene (HDPE), known for its excellent strength-to-density ratio, chemical resistance and flexibility. In the global hail net market, HDPE systems account for nearly 60% of installations, making them the most widely adopted solution for orchard protection.
Optimised light transmission
While blocking hail impact, the net structure allows sufficient sunlight penetration to ensure normal photosynthesis and sugar accumulation in citrus fruit.
Customised orchard integration
Hail nets can be custom-designed according to orchard row spacing and planting density, making them suitable for different citrus varieties such as blood oranges and pomelos without requiring major modifications to existing orchards.
Rain Shelters: A Barrier Against Splitting and Disease
Fruit splitting prevention
Rain shelters block direct rainfall from reaching the fruit, preventing excessive water absorption. In many cases, splitting rates can be reduced to below 5%.
Microclimate regulation
By limiting direct rainfall and improving airflow, shelters help lower orchard humidity, reducing the risk of fungal diseases such as anthracnose and black rot.
Efficient structural design
The arched structure fits orchard layouts and allows rapid drainage of rainwater, preventing water accumulation around the trees.
Additional Benefits During Harvest
Rain shelters can be equipped with adjustable or retractable opening systems, allowing easy access during harvesting without reducing operational efficiency.
Protective structures also offer additional advantages:
- Cleaner fruit surfaces, reducing dust contamination and improving export quality
- Reduced bird damage, limiting fruit losses caused by pecking
- Lower pesticide use, as physical barriers can partially replace chemical treatments
Global agricultural technology trends show that protective net systems are increasingly adopted because they reduce the need for chemical pesticides and support sustainable and organic farming practices.
This aligns closely with the EU Green Deal and the growing demand for residue-free, high-quality fresh produce.
Quality Premium and Greater Market Flexibility
For export-focused citrus growers in Spain and Italy, protective infrastructure delivers three key advantages.
Higher fruit quality
Fruit remains blemish-free, crack-free and visually uniform, enabling growers to produce premium “Extra Class” citrus with stronger export price premiums.
Extended on-tree holding period
Rain protection helps maintain fruit quality even during unstable weather, allowing growers greater flexibility in harvest timing and export scheduling.
Reliable contract fulfilment
Stable production quality reduces the risk of delivery delays or cancelled export orders caused by weather damage.
Proven Adoption Across Europe
Protective orchard systems are already widely used across European agriculture.
For example, the Spanish company Novafrut, with over 22 years of experience installing hail net systems, uses continuous elastic installation methods that maintain constant net tension. This allows hail to slide off efficiently while also providing wind protection and improved fruit quality.
Similarly, Italy’s Valente offers comprehensive orchard protection systems covering hail, rain, insects and sun protection, applicable to crops such as apples, pears, peaches and citrus.
Global market trends further confirm the value of orchard protection systems:
- Global hail net market revenue reached 13.5 billion RMB in 2025
- The market is expected to reach USD 2.12 billion in 2026 and USD 3.09 billion by 2035
- Orchards represent the largest application sector, accounting for over 50% of total demand
These figures highlight that protective infrastructure is becoming a mainstream practice in modern fruit production worldwide.
The Last Line of Defence for Your Harvest
In a year of reduced supply, simply protecting the crop can already mean success—and producing premium fruit can mean exceptional profits.
With Spain’s production forecast to fall by 9.72% and Italy’s by 6.12%, blemish-free “Extra Class” citrus will become an increasingly valuable commodity in export markets.
Late-season protection is not an expense—it is the final safeguard for an entire year of investment.
