Envirogro

How does PGG Wrightson Seeds tropical and subtropical seed varieties offer a higher value in comparison to the others? Envirogro® seed treatment!

Envirogro® seed treatment increases the seed count and purity of tropical and subtropical grasses and legumes. In the bare form, many such varieties can be difficult to establish because of the low flowability characteristics, and can potentially contain weed seed or other contaminants. Envirogro is a seed treatment process that can improve this common problem. Seed is processed and cleaned to various states improving purity. It is then treated with an insecticide (Gaucho) and coated giving each seedling a better chance to survive thus, reducing the risk of establishment failure.

Envirogro treated seed versus Bare Seed

Envirogro

• Reduces weed seed and other waste material
• Improves seed quality
• Less seed inactivity
• Better seed flow during sowing
• Improved success when sowing with Envirogro® seed
• Treated with insecticide for increased insect protection
• Improves ballistic properties 

Bare Seed

• Increased risk of weed seed contamination
• Harder to calibrate seeding equipment
• Higher rates of dormant and hard seed
• Seed bridging in sowing equipment
• Difficult to handle
• Limited access to necessary nutrients at germination
• Difficult to accurately match sowing rate to desired plant stand

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

So what exactly are the steps in the Envirogro® seed treatment process? 

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

Step 1: We start with the bare seed, harvested from the paddock and clean it to remove weed seeds, sticks, husks and debris.

Step 2: If working with a fluffy seed, we take the bare seed through a process of de-hulling, leaving only the caryopses and then, the seed is cleaned again to achieve high purity.

Step 3: Utilising state of the art technology, the caryopses is then pelleted and treated with insecticide to provide the seedling with improved success rates.

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.​
