Barley Straw Extract - 20L

Barley Straw Extract - 20L

Our extract is derived from barley straw and water steadily aerated for around 6 weeks. It is used to suppress the growth of aquatic algae and blanket weed. We supply 20L of extract in recycled 25L barrels for ease of shipping and handling.

Dose Rates

The extract should initially be added at 8l per acre of water surface.

The best method to ensure even distribution is to mix the extract with clean pond water at a rate of 1:5 i.e. 5l of clean water to 1l of extract.

This should be applied evenly via a knapsack sprayer.

Alternatively the extract can be added to a water inlet or the water outlet of a bank site pump. 

Regular applications of 2l per acre should continue throughout the growing season. 

To get the best results from barley straw extract spring/early summer application is advisable.
