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.

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.

The vineyard growers who call me after a failed net season — it’s almost never the wrong net type. It’s a drape system on a crew that can’t manage removal, or side netting on rows too tight for it.

In Marlborough and Central Otago blocks, switching from drape to side netting cuts harvest-period labour 25–30%. In Chilean Colchagua where hail and birds hit the same season, one overhead canopy handling both threats pays back in two seasons. The net choice follows the risk and the crew — not the other way around.

One UV grade does not fit every net — which is why we run different stabilizer packages across our lines.

A net spends its life in a specific way: under glass, in full sun, up for one season or for a decade. That pattern decides how much UV protection it actually needs. The mistake I see most is treating “UV-stabilized” as one thing — a grower stretches insect netting rated for a covered house over an open field, or assumes a shade-cloth assurance covers his new vineyard net.

The sun doesn’t read the product category; it reads exposure and time. This guide maps the real UV requirement for hail, shade, insect and vineyard nets, and shows how to turn your region and product into one spec.

Greenhouse shade cloth from China sounds simple until you realise it covers five completely different products. The buyer who orders ‘50% Aluminet’ when they need an energy-saving screen with 50% light transmission will receive a product that performs differently in winter — and costs differently too. Before comparing factories, resolve the product question: are you managing heat, light, energy, or photoperiod? The answer determines which factory can actually help you. — Kevin Lyu, EyouAgro

Buyers contact me about hail netting after a season that cost them 40% of their crop. By then, the decision is straightforward u2014 the hard question is specification. Most sourcing mistakes I see happen because the buyer chose the right factory but the wrong construction type. A Raschel drape factory cannot rescue you if your installation is a structured Leno canopy. Get the construction type right first. Then get the factory. u2014 Kevin Lyu, EyouAgro
Kenyan buyers who ask me to recommend a shade net supplier frame it as “who has the best quality.” In Kenya, the question is simpler than that.

For a Naivasha flower farm needing shade cloth this week, Greenspan Africa or Amiran Kenya hold local stock and deliver fast. For a Kiambu vegetable exporter planning 3 months ahead, direct import economics are worth calculating — most local Kenyan distributors source from Chinese manufacturers anyway, and you can remove that margin.

The right choice depends on your timeline and volume.

South African buyers who ask me to recommend a shade cloth supplier frame it as “who has the best quality.” The question worth asking is different.

A Western Cape apple farmer needs RedAnt in Ceres — they know local conditions. A commercial buyer across multiple provinces needs Knittex or Alnet’s scale. Most other local suppliers source from Chinese manufacturers and add a markup. For 20,000+ sqm with 3 months lead time, that margin is worth calculating directly.

The right supplier depends on your volume and timeline.

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.
After 28 years supplying shade cloth to farms across 55+ countries, one pattern keeps repeating: farmers underestimate heat stress until they lose production.

Heat stress costs the U.S. livestock industry $1.5–2.5 billion annually — and most of it is preventable.

The key is matching shade percentage to your climate. Dairy cows in hot regions need 80–90% shade with at least 5 m² per head. Beef cattle can work with 70%. Use UV-stabilized HDPE, orient east-to-west, and keep structure height above 3.6 m for airflow.

Roughly half the “my insect net is broken” emails we get aren’t about the net at all—they’re about ventilation that wasn’t redesigned for the airflow resistance the net added. After 28 years of seeing the same problem, the diagnosis is usually fast: heat builds up, humidity climbs, fungal disease shows up, and the grower assumes the net is failing. The net is fine; the system around it isn’t.

This guide walks through the four fixes that consistently solve the problem: larger effective vent area, supplementary fans on humidity triggers, mesh selection by pest spectrum, and a maintenance routine that keeps airflow from degrading over time.

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.
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.
