C-Weed 50

C-Weed 50 is a truly different biostimulant algal extract, that contains seaweed concentrate produced from a cool extraction process utilising only Ascophyllum nodosum from the Atlantic coast harvested from the intertidal zone and Micromix's unique AMIX Activated Humic-lignate Complex uptake technology. As it is harvested only during periods of rapid growth, this extraction method ensures that the natural biostimulant anti-stress and growth-enhancing compounds remain intact and are not denatured by heat. The Ascophyllum nodosum is hand harvested taking no more than 60% of any plant to ensure it is a renewable resource.

C-Weed 50 is typically rich in cytokinins and contains natural auxins, amino acids, and gibberellins along with alginic acid, mannitol, fucoidan and laminarin, C-Weed 50 can be formulated with additional nutrients like Nitrogen and Manganese where local fertiliser regulations dictate.

C-Weed 50 can be used on all crops. Field trials have shown that C-Weed 50 is up to 250% more biologically active in promoting disease and pest resistance and producing yield and quality increases in a wide range of crops, when compared with the same dose rate of conventionally produced competitor products.
