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.

Choosing the right rain cover directly affects cherry yield, fruit color, and overall orchard productivity. HDPE tarpaulin offers strong weather protection, while the 3-layer anti-dripping film enhances light transmission and fruit quality. Understanding the strengths of each material helps growers make cost-effective, climate-specific decisions that improve harvest consistency and market value.
Choosing the right shade cloth color is one of the most powerful ways to control tomato microclimate. This expert guide compares white, black, and aluminet nets using scientific evidence and real-world field performance, helping growers optimize fruit quality, reduce cracking, and improve heat resilience.
Choosing between 30% and 50% shade cloth is critical for tomato growers. Based on agronomic studies and field performance, this guide reveals how shade density impacts heat stress, fruit cracking, sugar content, and overall marketable yield—helping you make climate-specific decisions with confidence.
Based on vineyard projects we’ve supported across different regions, I’ve repeatedly seen that bird net mesh size is often chosen too simply—many growers focus only on “bird size” and overlook how net structure, installation method, and insect pressure interact in real vineyards.

In practice, vineyards using larger mesh drape nets for bird-only pressure achieved good protection at lower cost, while sites facing bees or wasps needed smaller square-mesh systems to avoid secondary losses. The difference was not theoretical—it showed up in fruit damage, labor efficiency, and replacement cycles.

This guide is written from those field observations to help growers select bird net mesh sizes that match their actual vineyard risks, rather than over-specifying or under-protecting based on assumptions.
Based on feedback from vineyard clients in different regions, we’ve found that insect netting is not a default choice for vineyards—it’s a conditional tool that only works when pest pressure and climate justify it.

In several projects, the bigger risk was not insects, but airflow restriction and higher humidity after netting, which can quietly increase disease pressure if mesh is chosen too fine or coverage is too closed.

This guide explains when insect netting makes sense, when it usually doesn’t, and how to balance exclusion vs ventilation—so growers can avoid “over-protecting” and protect grape quality more reliably.
Based on field observations from multiple vineyard netting projects, I’ve found that mesh size is more often misjudged than material or UV specifications.

In many cases, growers focus on maximum exclusion without realizing that airflow restriction and microclimate imbalance create bigger risks than pests themselves.

This guide is written from a practical, project-based perspective to explain how vineyard net mesh size influences protection, ventilation, and grape quality, and how to choose the right aperture before moving into detailed system design.
In the greenhouse and net-house systems we’ve supported, airflow loss is often caused by dirty nets—not the mesh itself.

From a technical support perspective, the biggest avoidable mistake is bleach: it can brittle the yarn, weaken tensile strength, and permanently deform apertures.

This guide shows a safe step-by-step cleaning method, what to avoid, and how to inspect, repair, and store nets to extend service life.
We’ve supported multiple greenhouse and high-value crop projects where “mesh count” selection failed—because mesh labels don’t equal real aperture.

From a technical support perspective, the reliable method is thorax width → max aperture → airflow plan: choose the smallest opening needed for exclusion, then design ventilation area (or rectangular / mixed-net zoning) to avoid microclimate penalties.

This guide gives a thorax-width reference table, aperture formula, and a practical decision flow you can apply to any crop.
Based on my field experience working with vineyard net installations across different regions, I’ve found that most grape damage issues are not caused by the net itself, but by installation details such as timing, tension control, and accessory selection.

In real-world projects, factors like net slack, clip spacing, fruit-zone clearance, and installation sequence often determine whether a system protects grapes reliably or creates unnecessary mechanical stress during the season.

This guide is written from an installation engineering perspective to help growers avoid common mistakes and build vineyard netting systems that perform consistently under real field conditions, not just on paper.
All articles are written based on first-hand project experience, on-site installation work, and long-term performance data collected from orchards, vineyards, greenhouses, and commercial growers worldwide.
