COBBER G

Organic Copper for Natural Crop Defense and Copper Nutrition

COBBER G is an advanced organic copper solution designed to support crop health, reinforce natural plant defenses and correct copper deficiencies through highly efficient foliar and soil applications. Its formulation is based on copper complexed with gluconic acid, a natural organic complexing agent that favors copper mobility, transport and assimilation within the plant. This makes COBBER G a high-performance alternative for growers seeking an effective copper-based solution with systemic action and improved crop compatibility.

Unlike conventional copper products that mainly act on the plant surface, COBBER G is designed to move within plant tissues, helping crops respond more efficiently to nutritional imbalances, abiotic stress and disease pressure. Its systemic activity contributes to a more complete and balanced crop response, supporting both preventive strategies and corrective nutrition programs.

One of the key strengths of COBBER G is its ability to stimulate the synthesis of phytoalexins, natural compounds produced by plants as part of their defense mechanism. By enhancing this physiological response, COBBER G helps crops strengthen their own resistance capacity, contributing to improved vitality, resilience and overall plant performance during sensitive growth stages.

COBBER G is especially valuable in integrated crop management programs where copper nutrition, plant defense activation and fruit quality must be addressed together. Its high assimilation, biodegradable nature and non-staining behavior make it suitable for a wide range of professional crops, including citrus, fruit trees, olive trees, vineyards, cereals, rice and horticultural crops.

The product can be used by foliar application to provide a fast and targeted response, or through fertigation to support copper nutrition and systemic crop reinforcement from the root zone. This flexibility allows COBBER G to be integrated into different agronomic strategies depending on crop type, phenological stage, environmental conditions and production objectives.

COBBER G also helps improve fruit conservation, making it a valuable tool for crops where post-harvest quality, commercial appearance and shelf-life potential are important. Since it does not stain the plant, it is particularly suitable for high-value fruit and vegetable production, where visual quality is a key market requirement.

Thanks to its organic complexation technology, systemic action and dual function as a fungicide-bactericide support solution and copper deficiency corrector, COBBER G offers growers a reliable and efficient product for maintaining healthier, stronger and more productive crops throughout the crop cycle.

Origin and Certifications

COBBER G provides a complete technical solution for crops requiring copper nutrition, improved physiological resistance and support against fungal and bacterial pressure.

It helps crops maintain performance under abiotic stress while reinforcing their natural defense mechanisms. Thanks to its systemic action and organic complexation, COBBER G offers efficient copper assimilation without staining the plant, making it an advanced tool for high-value crop programs.

Main benefits include:

  • Helps prevent abiotic stress in plants.
  • Supports natural fungicidal and bactericidal action.
  • Corrects copper deficiencies.
  • Stimulates phytoalexin synthesis.
  • Enhances the crop’s natural defenses.
  • Offers systemic action.
  • Provides high assimilation.
  • Does not stain the plant.
  • Helps improve fruit conservation.
  • Suitable for foliar and soil application.

Stronger Natural Crop Defense

COBBER G stimulates the synthesis of phytoalexins, natural defense compounds produced by plants in response to stress and pathogen pressure. This helps strengthen the crop’s internal protection mechanisms and supports healthier development throughout sensitive growth stages.

Efficient Copper Nutrition

The copper in COBBER G is complexed with gluconic acid, which favors copper transport inside the plant. This improves the efficiency of copper delivery and makes the product especially valuable in programs designed to prevent or correct copper deficiencies.

Systemic Action

Unlike conventional copper products that remain mainly on the surface, COBBER G is designed with systemic action, helping the active copper move within the plant and support internal physiological functions.

No Plant Staining

COBBER G does not stain the plant, making it suitable for crops where visual quality, fruit appearance and commercial presentation are important.

Fruit Conservation Support

By contributing to stronger plant health and better crop defense, COBBER G helps improve fruit conservation and post-harvest quality potential.

Flexible Application

The product can be used through foliar application and fertigation, depending on the crop, phenological stage and agronomic objective.

COBBER G stands out for its organic copper complexation technology. The copper ion Cu²⁺ is complexed with gluconic acid, a natural organic molecule that favors the transport of copper inside plant tissues. This improves mobility, assimilation and overall crop response.

Its main technical advantages are:

  • Copper complexed with gluconic acid for improved transport and assimilation.
  • Systemic activity, supporting internal crop defense responses.
  • Phytoalexin stimulation, helping crops reinforce natural defenses.
  • High efficiency in copper nutrition and crop protection strategies.
  • Biodegradable formulation.
  • Non-staining behavior on plant surfaces.
  • Dual agronomic value: bioprotection support and copper deficiency correction.
  • Compatible with foliar and soil strategies in professional crop programs.
