I am Kevin Lyu, Founder of EyouAgro
A 28-Year Legacy Built on a Single Promise:
Protecting the Harvest, Empowering the Grower.

Welcome to my page.
For the past 28 years, my team and I have provided crop protection solutions to over 1,300 clients in more than 55 countries.
Here, I want to share my story and how we can help you achieve a better harvest.

Over the years, I’ve worked directly with orchard owners, vineyard managers, greenhouse growers, and agricultural importers—helping them design, install, and optimize crop protection netting systems that stand up to real-world farming conditions.
Where It All Began
A Father's Factory, A Son's Purpose.

The hum of machinery was the soundtrack to my childhood, and my father, its conductor.

Wind, frost, rain, and sun nourish everything that grows, but sometimes they can also cause harm.
“How can we better protect them?”
I found the answer to this question in my childhood.

I often saw my father working with his beloved machines in his factory. He told me that the netting they produced was like a suit of strong ‘armor’ for the plants, guarding them against the harshness of nature. At that moment, I felt a sense of wonder and pride.

Today, I have taken over my father’s business, continuing this legacy of protection.
That early understanding shapes how I evaluate netting systems — not by how they look in catalogs, but by how they perform season after season in the field.

I am fully dedicated to advancing crop protection technology, committed to working alongside every grower with more advanced and eco-friendly solutions.

We firmly believe that by protecting every crop, we are ultimately safeguarding the hard work of growers and contributing to a more abundant, quality future for the world.

Our Philosophy
More Than Protection, It's Precision Growth Control

We use optical and material science to turn a simple net into a high-efficiency crop growth regulator

By precisely regulating shade and ventilation, we build a comprehensive crop protection system. It actively defends against harsh conditions like hail and high winds, ensuring a stable environment for optimal growth

A stable microclimate allows crops to devote more energy to fruit development. Unique diffused light technology boosts overall photosynthesis for better sugar content and flavor.

This is a cutting-edge technology. Our colored Agrotextiles selectively filter the light spectrum, sending specific growth signals to plants to stimulate flowering, enhance color, or delay harvest.

A Solution for Every Challenge

From universal threats to unique environmental challenges, our comprehensive product line has been meticulously crafted over 28 years to provide a specific and reliable answer for every grower.

A Solution for Every Challenge

I believe the best solutions are born from collaboration. Let’s talk about the unique challenges of your land and craft a protection strategy that’s tailored specifically for you.

Sharing is the Best Way to Grow

“The more I share, the more I grow.” I firmly believe this.
Here, I’ll share my 28 years of experience to help you better understand and use agrotextiles.

17 mesh and 25 mesh may look similar, but they serve very different jobs: 17 mesh is built for orchards and maximum airflow, while 25 mesh is designed for vegetables and medium-pest exclusion.

This guide compares real-world performance using pest thorax width vs aperture size, so you can avoid under-protection, overheating, and wasted investment.

In real greenhouse projects we’ve supported, the 50 vs 75 mesh decision is rarely about “which one is better” — it’s about which risk you’re prioritizing. 75 mesh can be a game-changer when thrips or virus pressure is high, but it also brings a very real ventilation penalty that shows up as higher temperature, higher humidity, and faster disease pressure if the structure isn’t engineered for it. This guide breaks the choice down the same way our technical team does on-site: aperture (microns) → pest thorax width → ventilation capacity. If you want reliable exclusion without turning your greenhouse into a humidity trap, this comparison will give you the decision rules and the practical checkpoints to choose confidently.

In real greenhouse and tunnel projects we’ve supported, the biggest mistake I keep seeing is treating “25 mesh vs 40 mesh” as a small upgrade. It isn’t. That one step changes which pests you can reliably stop (especially aphids, whiteflies, and SWD), and it also changes how your structure breathes—temperature, humidity, and disease pressure. This guide breaks the decision down the way our technical team does in the field: aperture logic + pest morphology first, then ventilation reality. By the end, you’ll know exactly when 25 mesh is the smarter choice for heat-prone vegetables, and when 40 mesh becomes the safer baseline for greenhouse crops and berry systems.

In berry projects we’ve supported, we’ve seen SWD control is a real-aperture problem—not a “mesh label” problem.

From a technical support perspective, we start with SWD thorax width → max safe aperture, then protect the crop without creating heat/humidity that drives Botrytis and soft fruit.

This guide compares 25 vs 32 mesh and the airtight installation checks that make exclusion reliable.
Across the greenhouse and orchard projects we’ve supported, most “insect netting failures” trace back to one mistake: choosing by mesh number instead of true aperture (µm) and pest thorax width.

Once you compare real opening size with pest morphology, exclusion becomes a mechanical rule—not guesswork: sometimes a 30–80 µm difference decides success or failure.

This guide breaks down penetration physics, a thorax-width reference table, and a practical mesh-selection workflow—so you can choose nets by microns, not labels.
This case study reveals how a commercial vineyard solved long-standing netting issues—not by changing the net, but by changing the process. By shifting from skill-based to standardized installation, the vineyard achieved consistent performance across seasons, proving that system design matters more than material choice.
Insect netting is one of the most effective and sustainable ways to protect crops, improve microclimate stability, and reduce pesticide reliance. Choosing the right mesh size and structure directly affects pest exclusion efficiency, airflow, and crop yield quality.
Across greenhouse and net-house projects we’ve supported, we’ve found that the right insect net is a balance between exclusion and airflow—not simply choosing the finest mesh available.

From a technical support perspective, the most reliable workflow is Pest → Crop → Mesh/Aperture → Installation sealing, because small gaps and poor ventilation can cancel out any mesh advantage.

This guide gives you a clear “101” decision map, product options (17–75 mesh), and practical selection tables you can apply to real farms.
Across farm and greenhouse projects we’ve supported, we’ve learned that “one mesh for everything” is the fastest way to lose either airflow or protection.

From a technical support perspective, the most reliable method is Crop → Key pest → Minimum safe aperture → Ventilation & pollination plan, because a net that blocks pests but overheats the crop is not a win.

This guide gives crop-by-crop mesh recommendations (vegetables, berries, brassicas, leafy greens) and highlights where SWD, thrips, and pollination constraints change the decision.
Insect netting protects crops, but it also adds airflow resistance at vents—often leading to heat buildup and excess humidity if ventilation is not adapted.

In the projects we’ve supported, the fix is rarely “change the mesh only”—it’s a system approach: increase effective vent area, add the right fans, match mesh to climate + pest spectrum, and keep nets clean and tight.

This guide gives practical design strategies to keep greenhouses breathable while staying insect-proof.
Shade cloth solves major heat and sunscald issues, but poor management can trigger cracking, blossom drop, weak color, fungal diseases, and low yield. This guide organizes all problems into five clear diagnostic categories with practical, actionable solutions—helping growers stabilize microclimate, protect fruit quality, and prevent costly mistakes.
Overhead netting isn’t just a net—it’s a long-term structural system. This guide walks you through key decisions, step-by-step installation, tensioning, and maintenance planning to ensure durability and performance. Perfect for vineyards facing repeated hail or bird risks and seeking consistent, season-to-season protection with predictable results.
Correct shade cloth installation impacts tomato performance more than the shading percentage itself. This expert guide explains the ideal height, essential ventilation design, and irrigation adjustments required to prevent heat stress, reduce cracking, and stabilize microclimate conditions for high-quality tomato production.
From what I’ve seen across different vineyards, netting problems often start before the net is even installed—usually because the timing was misjudged.

In real vineyard operations, installing too early can interfere with spray programs, airflow, and canopy management, while installing too late exposes fruit to bird pressure, sunburn, and weather risks right when damage is hardest to reverse.

These field notes are shared from a practical vineyard management perspective, helping growers align net installation with vine growth stages, regional climate patterns, and operational workflow to protect fruit without creating new problems.
A well-designed shade house is critical for healthy coffee seedlings. This guide covers frame height, net tension, post spacing, drainage, and pest control. Discover key construction tips, materials to use, and how to set up a hardening zone—ensuring strong growth, better survival, and long-term nursery success.
