Definitions

  • This transposition of several kinds of gene made the cultures OGM resistant to glyphosate, glufosinate (Aventis) or other agrochemicals.
  • the velocity of entrance of glyphosate through the membrane of the leaves of the weeds is about 4 hours, while the velocity of biodegradability by the bacteria in the soil or on the surface of the leaves if they are wet, is 5 days, to reduce the amount of glyphosate and metabolites to values below the detection limit of 0,5 microgram per liter.

Abstract

Les résidus des produits agrochimiques et de leurs métabolites dans le sol inquiètent beaucoup les autorités et l'opinion publique pour des raisons sanitaires. Nous avons observé que certaines bactéries et d'autres micro-organismes existant dans le sol pouvaient s'adapter, après plusieurs générations, à des types spécifiques de produits agrochimiques et les digérer. La présente invention concerne par conséquent un produit qui consiste en un mélange d'un concentré de bactéries appropriées avec de l'eau ou un autre solvant et le produit agrochimique à pulvériser. La présence du concentré de bactéries permet d'assurer la biodégradabilité rapide du produit agrochimique sans en réduire son efficacité. Le concentré de bactéries peut être mélangé avec le produit agrochimique lors de son application, mais peut également être ajouté lors de la fabrication du produit agrochimique.
