A sustainable weed suppression platform

 

The Problem

 

Modern agriculture and bioproducts production achieves optimum yield through continuous input of phosphate based feeding and powerful herbicides/pollution control chemicals, the excessive use of these contaminates food, soil, culture media and waterways.

 

Together with biological resistance/adaptation and poor phosphorous utilization, are becoming crucial challenges for the future of not only agriculture and bioproducts platforms, but the global ecosystem.

 

 

 

Our Solution

 

“Engineer crops that can outcompete weeds without the need of using herbicides, friendlier to the environment and biodiversity”.

 

Based on the use of phosphite as the source of phosphorous (instead of phosphate) we developed a novel and effective dual fertilization and feed control system, which can achieve a sustainable agriculture/bioproducts production through the application of a single phosphorous compound for any transformable crop or biomaterial production system. This new strategy is based in the production of plants (or algae, fungus or bacteria) capable of using alternative phosphorous sources that are not metabolized by microorganisms and weeds. When introduced into the major global crops (or algae, fungus or bacteria cultures), this system brings about significant savings to producers as well as competitive yields in a more sustainable and ecofriendly production platform.

Field tests in Argentina and USA 2013

Field tests in Argentina 2013

 

Two tests successfully realized in 2013 in the regions of Pergamino and Chabuco:

 

1.- Calibration & Efficiency of Phi as a herbicide (herbistatic).

 

2.- Efficiency of Phi as a fertilizer for transformed tobacco plants.

 

  • Plants initially grown in greenhouses and transferred to greenhouses.
  • 2 fields: low P, about 10 ppm
  • 2 transgenic events + control (non transformed tobacco)
  • 2 levels of phosphate (no applied and high),  6 rates of phosphite (0 to 120ppm)

Seedling growth of transgenic tobacco without the use of herbicides and 50% Phosphite fertilization.

Field tests in USA 2013

 

One test successfully realized in 2013 in Yuma, Arizona in partnership with Arcadia:

 

 Complementary to Efficiency trial in Argentina

 

  • Supported and organized by Arcadia.
  • MTA signed.
  • Tested in Yuma Arizona and Complementary to Argentina trial with tobacco.
  • Seed been propagated for trial (in Mexico).
  • Documentation, labels, and other paperwork completed (by Arcadia).

Nowadays we are starting test fields in the USA and Mexico, with Cotton and Soybean and in the near future with Corn.
