Client Profile

Vineyard Overview

● Vineyard Name: Château de la Vigne

● Location: Bordeaux, France

● Size: 15 hectares (premium wine grape production)

● Challenge: Managing fungal diseases while maintaining organic certification

Introduction

At Dexing Biotechnology Co., Ltd, we develop natural solutions for sustainable viticulture. Our Trichoderma harzianum biofungicide was recently implemented at Château de la Vigne, a respected vineyard in Bordeaux, France, to combat soil-borne pathogens and improve grape quality without synthetic chemicals.

The Challenge

The vineyard faced persistent issues with:

● Botrytis cinerea (gray mold) affecting grape clusters

● Root rot reducing vine vigor

● Pressure to reduce copper-based treatments while staying organic

Our Solution: Trichoderma harzianum Biocontrol

We introduced a specially selected Trichoderma harzianum strain to:

● Act as a natural shield: Outcompeting harmful fungi like Botrytis

● Strengthen vine roots: Enhancing nutrient uptake and drought resilience

● Support soil biodiversity: Creating a balanced ecosystem underground

Application Approach

● Soil incorporation during dormancy

● Targeted sprays at key growth stages

Observed Benefits

After two growing seasons, the vineyard reported:

● Healthier grape clusters with fewer mold outbreaks

● More consistent vine growth across different terroir zones

● Reduced reliance on copper treatments while maintaining organic status

Winemaker's Perspective

"We noticed the vines seemed more resilient, especially in humid periods. The grapes arrived at harvest with better skin integrity, which matters tremendously for our wine quality." — Luc Moreau, Vineyard Manager

Why This Works in Bordeaux

Bordeaux's maritime climate creates ideal conditions for fungal diseases. Our Trichoderma harzianum thrives in these environments, forming protective relationships with vine roots while naturally suppressing pathogens.

Sustainable Advantages

● Preserves terroir expression by avoiding chemical interference

● Builds long-term soil health for future generations of vines

● Aligns with organic and biodynamic principles

Future Directions

Château de la Vigne plans to expand use to their entire estate and experiment with our mycorrhizal blends for additional benefits.
