Seasol Stress-aid improves frost tolerance in plants through biochemical, molecular, and physiological changes.

Stress-aid reduces frost-induced electrolyte leakage by maintaining membrane integrity during freezing stress.

Stress-aid helps regulate sugar and acids in plants. Sugar accumulation helps plants to reduce frost stress by playing an essential role in stabilising various biological components such as the cellular membrane and membrane-bound organelles.

Seasol Stress-Aid is made from Durvillaea potatorum and Ascophyllum nodosum. Durvillaea potatorum is sourced from King Island and the west coast of Tasmania where the kelp is swept ashore after storms. Collection of storm cast kelp is sustainably managed under licences issued by the Tasmanian Government. Ascophyllum nodosum is widely used in the northern hemisphere where it is sustainably harvested from managed kelp beds. The kelps are blended together in our own dedicated processing facility near Launceston to produce the wonderful seaweed solution that is Seasol Stress-Aid.

Crops Rates Comments
Tree & Perennial Crops Apply 5 - 10L/Ha. Use the lower rate on young crops. Apply up to 10 days prior to predicted cold and heat stress to aid in crop resilience. Apply after stress events to aid in crop recovery. Apply at times of high crop potassium demand. Can be applied multiple times across the season.
Annual Crops Apply 5 to 10L/Ha once per month or in split applications.
Turf Apply at 10L/Ha (1mL per sq metre)
Parks & Gardens Street Trees Dilute 2.5mL/L (2.5L/1,000L) as an addition to standard watering practices, e.g. water cart. 1ml square metre with a knapsack or small sprayer.
