How It Works

Trich-a-soil is applied to soil or growing media where it will colonise the root zone to create a healthy growing environment for turf and other plants. It contains trichoderma which are beneficial saprophytic fungi that feed on sugars excreted by plant roots as well as dead plant material. Established colonies can help create a growing environment less favourable to soil borne pathogens.



Trich-a-soil contains a living fungus that is sensitive to a number of fungicides including benomyl, imazalil, propiconazole, tebuconazole and triflumizole. Read the front panel of fungicide labels to determine if the active ingredients are compatible. A full list of compatible fungicides is available from OCP if required. 

When an incompatible fungicide has to be used, Trich-a-soil can be reapplied 10-14 days later.


Additional Information

For optimum results, the soil must remain moist and not too acidic or alkaline.

Unused Trich-a-soil should be sealed and kept refrigerated.
