Stella Maris

Stella Maris supplements a well-balanced crop nutrition program.

Unlock every acre of your field. Stella Maris® is the critical step to condition plants to produce when it matters the most by giving your crop strong early growth, increased nutrient uptake, and the ability to tolerate whatever Mother Nature dishes out for your best season yet. Stella Maris is a high concentrate liquid Ascophyllum nodosum seaweed extract biostimulant designed for soil and foliar uses in conventional and organic crops.

Stella Maris enhances crop quality and productivity by supporting root growth and early establishment, boosting nutrient use efficiency, and helping plants increase their tolerance to challenging growing conditions that can rob yield, such as drought, heat, chill, and salinity.

Stella Maris Benefits

  • Improves root initiation, root elongation, branching and mass, which leads to improved plant establishment and facilitates greater uptake of water and nutrients.
  • Optimizes plant nutrient availability in the soil through the chelation effect of mannitol and alginic acid. This enhances nutrient uptake throughout the growth cycle and creates conditions for rapid plant growth and development
  • Improves crop tolerance to abiotic stress conditions such as heat, chill, drought and salinity by enhancing the plant’s production of stress relieving compounds (antioxidants)
  • Helps regulate water loss through regulation of the stomata in times of drought which improves moisture retention and reduces wilt
  • Increases fruit and vegetable quality and uniformity, with better sizing, reduced culls, better color, delayed senescence,  higher brix, and increased shelf life
  • Stella Maris is an easy-to-use water-soluble liquid formulation for in-tank compatibility with most crop nutrition, herbicides, fungicides, and insecticides. Always read and follow the label directions.
