Professor Mac 3 in 1 is a complete lawn and garden program in one application – lawn food, wetting agent and organic insecticide. It contains Eucalyptus Oil and Tea Tree Oil. Both of these University tested ingredients are plant extracts and replace the need to use synthetic pesticides. Professor Mac 3 in 1 acts as an effective control against two of the most common lawn insect pests, Lawn Army Worm and African Black Beetle. The in-built wetting agent helps to move the plant extracts into the soil profile where they can contact the insects and effectively control them before they damage the grass.

How to use:

To use as an insecticide on lawns for the control of Lawn Armyworm, dilute 1 L of concentrate into 20 L of water and apply over an area of 50 square metres. For treatment of African black beetle dilute 1 L of concentrate into 20 L of water and apply over an area of 8 square metres. Please check the label for more details.

To use as a fertiliser on lawns dilute 1 L of concentrate into 20 L of water and apply over an area of 200 square metres. To use as a wetting agent on a lawn, dilute 1 L of concentrate into 20 L of water and apply to an area of 125 square metres.
