Trichoderma harzianum

Trichoderma harzianum is a highly effective biocontrol agent known for managing soil-borne diseases such as collar rot, stem rot, root rot, and wilts. It also provides strong protection against damping-off, foot rot, downy mildew, and other related fungal diseases. T. harzianum is particularly well-suited for neutral to acidic soils, making it ideal for use in hilly regions. Additionally, it exhibits natural resistance to certain fungicides like carbendazim and metalaxyl, allowing for combined application to control multiple diseases simultaneously.
