Product Type
Ascophyllum nodosum seaweed extract bioactivator
MARE
Ascophyllum nodosum seaweed extract bioactivator for flowering, fruit set, fruit growth and crop tolerance to water, salinity and low-temperature stress.
MARE is a liquid seaweed extract bioactivator based on Ascophyllum nodosum. The extraction process is designed to retain naturally occurring phytohormones, vitamins, carbohydrates, mannitol, alginates, organic acids and macro- and micronutrients.
It is intended for critical crop stages including active growth, flowering, fruit set and ripening, as well as periods of adverse environmental conditions. The product is rapidly taken up through foliar and root systems and is suitable for a wide range of fruit, vegetable and extensive crops.
For programmes that require seaweed biostimulation together with NPK nutrition and silicon, see SIL MARE NPK, an Ecklonia maxima seaweed NPK fertilizer with silicon.

How it works / Technical advantages
MARE is based on Ascophyllum nodosum seaweed extract and contains naturally occurring phytohormones, vitamins, carbohydrates, mannitol, alginates, organic acids and nutrients. The source describes these components as acting synergistically to activate plant development.
The quantified formulation contains 20% seaweed extract, 4% nitrogen, 3.5% potassium oxide, 3% alginic acid and 0.8% mannitol, with a density of 1.09 g/cc. It is rapidly taken up through leaves and roots and can be integrated into foliar and irrigation-based programmes.
Application rates and timing
Application Guidance: Follow the crop- and stage-specific programmes below. MARE may be applied by spraying or sprinkling and can also be used through drip irrigation or fertigation systems. The source states that it may be applied together with pesticides. Use only documented crop-specific rates; no separate fertigation rate is stated.
