Agricultural Insights & Technical Knowledge

Scientific insights and technical knowledge about light, UV, microclimate and netting performance – to help you protect your orchard with confidence.

Deep-dive technical content · Written by EyouAgro engineers · Field-tested with growers worldwide

After discovering the value of agricultural knowledge—whether from your own experience or through our Academy—you quickly realize how much easier farming becomes when information is clear, practical, and grounded in real science.
This inspires you to learn deeper, improve your farm decisions, or train your team with reliable guidance.

But soon, a new set of questions naturally appears:

Where should I start learning? Which topics matter most to my crops?
What techniques or methods are proven to work in real fields?
Are there step-by-step guides that help me solve specific farming challenges?
If I need expert advice, who can I talk to—and where can I get it?

Check out our Academy Guides or connect with us for more hands-on support.

How to Build a Vineyard Trellis: Post Spacing, Wire & Netting Guide

The vineyard owners who call me about trellis failures — it’s almost never the wire gauge. It’s end-post anchoring that collapses under cumulative lateral wire tension after the first season of full vine load.

In New Zealand and Chilean vineyards I supply netting to, I’ve seen 2.5mm high-tensile galvanised wire on treated Pinus posts hold for 15+ years — but only where end posts were set with diagonal strut anchoring at 45°. Without that, even 3mm wire pulls the row inward within two or three seasons as vine weight builds.

Spend 30% of your trellis budget on end posts and anchoring. The middle posts are just spacers.

Japanese Beetles: 11 Facts You Should Know

The greenhouse growers who contact me about Japanese beetles — it’s almost never the wrong pesticide. It’s the wrong approach.

Spraying kills the beetles but also kills your pollinators. I supply fine-mesh exclusion netting to US greenhouse operations that have switched from spray programs to barrier protection during peak season (June–August). Two seasons of netting costs less than one year of monthly sprays.

Japanese beetles have no natural predators in North America. Netting is the only solution that stops them without disrupting the ecosystem.

Hail Protection

3 Types of Hail Netting: Drape, Leno & Quad Crossover Compared

The orchardists who call me after a hail season — it’s rarely the netting that failed. It’s Raschel drape on a flat roof system it wasn’t built for, or Quad Crossover where drape does the same job for half the price.

In apple orchards with 3m row spacing, Leno Woven lasts 8–10 years and stops 20mm+ hailstones reliably. Quad Crossover is worth the cost when hail regularly exceeds 30mm — most growers in high-risk areas recover it within two harvests.

Choose the type for your hail risk and orchard layout. Paying more isn’t always the right answer.

SWD Mesh Requirements: A Complete Guide for Berry Growers

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.

Photoselective Nets: Red, Grey & Yellow Insect Netting Science

Through years of supporting greenhouse growers, I’ve seen firsthand how photoselective insect nets—especially in red, grey, and yellow—can transform pest control and microclimate management.

Rather than simply blocking pests, these nets manipulate light to disrupt pest behavior and enhance the growing environment.

Mesh Size & Pest Exclusion Physics: The Scientific Basis of Insect-Proof Netting

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.

How One Vineyard Stopped Wasting Good Netting

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.

Why System Design Matters More Than Net Performance in Large-Scale Vineyards

As vineyard scale increases, manual netting often struggles to keep up—leading to inconsistent tension, installation errors, and operational delays. This article explores how mechanized vineyard netting systems bring process-level stability, reduce labor input by up to 70%, and extend net longevity through consistent tension control and structured deployment.

How Birds, Insects, and Mesh Design Interact in Grapevine Protection

Vineyard netting does not fail because the mesh is weak—it fails when bird behavior and insect movement are misunderstood. This article explains how biological exclusion works in real vineyards, showing why visibility, entry paths, and movement patterns matter more than mesh size alone, and how system-level design turns netting into effective, predictable protection.
