Envirogro

The Envirogro seed treatment process gives PGG Wrightson Seeds tropical and subtropical seed varieties a better start. The tailored process cleans, treats, and improves the bare seed count and purity of tropical, subtropical grasses and legumes.

To remove the common problems associated with bare seed, the Envirogro seed treatment process cleans and processes seed to various states improving purity and bare seed count. It is then treated with an insecticide (Gaucho®) and coated with a polymer and talc giving each seedling a better chance to survive. If the species requires, the bare seed is taken through a process of de-hulling leaving only the caryopses, before being coated and cleaned to achieve a high purity.

Envirogro treated seed versus Bare Seed

Envirogro

• Coated with insecticide, polymer and talc
• Improved seed flowability and ballistic properties
• Improves seed quality and purity
• Increases bare seed count for a higher return on investment
• Produces a clean, uniform seed
• Reduced risk of establishment failure 
• Removes seed husk from the caryopsis (if required)
• Removes weed seed, waste material and contaminants

Bare Seed

• Difficulty achieving accurate seed placement to match desired sowing rates
• Difficult to handle efficiently
• Harder to calibrate seeding equipment
• High risk of insect invasion
• Includes seed, sticks and other contaminants in seed count/seed bag weight
• Increased risk of weed seed contamination
• Potential limited access to necessary nutrients at germination
• Seed bridging in sowing equipment

Recommended for

Tropical and subtropical grasses and legumes

Contains

Gaucho®, a systemic insecticide for protection against Red Legged Earth Mite and Blue Oat Mite. Please note, in some cases where high numbers of mites are present, a follow up insecticide treatment may be necessary

How it works

The process consists of 3 important phases that seperate Envirogro treated seed from ordinary tropical and subtropical treated seed. 

Phase 1 Cleaning: Bare seed is harvested from the paddock and cleaned of contaminants and debris.

The Envirogro seed treatment process is tested after every phase.

Phase 2 Dehulling (species specific): Bare seed is taken through a process of de-hulling, leaving only the caryopses - the important bit. Then the seed is cleaned again to achieve high purity.

The Envirogro seed treatment process is tested after every phase.

Phase 3 Coating: Utilising state of the art technology, the caryopses is then pelleted; this includes a coating of insecticide, polymers and talc to provide the seedling with improved success rates.

The Envirogro seed treatment process is tested after every phase.

To achieve optimum results, seed germination is tested after every phase of the Envirogro seed treatment process. Don’t forget to ask us for a purity and germination certificate to see the seed count per kg and live seed count with your next order.​
