DUCKWEED CONTROL
[EPDU]

DUCKWEED CONTROL
 £14.20 
Clearing duckweed by hand usually leaves a small amount which will regrow quickly. This natural bacterial culture removes nutrients key to the growth of duckweed (Lemna minor), inhibiting its return. Duckweed Control will not harm fish, wildlife or other plant life in the pond.

Treats 4500 lt for 13 weeks.

Duckweed Control is best applied in Spring as soon as duckweed growth is seen but once the pond water temperature has reached 8 degrees to ensure effective microbial activity.

Remove as much of existing duckweed as possible prior to treatment

Initial dose: For every 450 litres (100 gallons) of water to be treated add 25ml of product to a watering can or bucket of pond water.

Mix well and pour evenly over pond surface.

Maintenance dose: 10ml per 450 litres weekly until duckweed stops growing.
