YaraAmplix OPTITRAC

YaraAmplix Optitrac™ is a liquid biostimulant formulation for foliar applications based on a blend of nutrients and bioactive compounds extracted from the algae Ascophyllum nodosum. It was developed to alleviate the impact of abiotic stress conditions (e.g. cold and drought) and help the plant during periods of high metabolic demand in order to stimulate flowering, fruit set and improve yield quality and quantity.

YaraAmplix OPTITRAC™ is an easy to use liquid formulation containing:
• Boron, zinc, nitrogen and potassium - to enhance the effect of the bioactive compounds.
• Sugar alcohols - to improve the mobility of boron.
• Amino acids - critical to various aspects of plant metabolism and to aid resilience during times of abiotic stress.
• Organic acids - to improve micro-nutrient uptake.
• Polysaccharides - to mitigate the impact of abiotic stress.
• Vitamins - for anti-oxidant protection properties.
• Humectant, for uptake - to prolong the foliar nutrient
