Trichoderma (Trichoderma spp.), inoculant 
Green-spored soil fungus, multiplied on rice in biofactories and agricultural schools.
Characteristics
- Colonises root surfaces and organic matter; recognisable by its green colour (EPA Nº7 and INTA Perico, 2021).
- Some strains are approved as plant-protection active substances in the EU: they may only be used as authorised commercial products, never multiplied at home for that purpose.
Role in the preparation: Starter inoculum ("mother culture") to multiply it on rice; soil and substrate inoculant.
Caution: Buy an identified inoculant and store it as the label says; wear gloves and a mask when handling powders; check local regulations before any use.
