Disease suppression in Ganoderma-infected oil palm seedlings treated with Trichoderma harzianum

Disease suppression in Ganoderma-infected oil palm seedlings treated with a conidial suspension of Trichoderma harzianum FA 1132 was tested in plant house conditions to determine the effectiveness of the fungus as a biocontrol agent. The highest efficacy of control was achieved by treatment right af...

The highest efficacy of control was achieved by treatment right after artificial infection; the total number of infected plants was reduced to give the lowest disease severity index (DSI) value of 5.0%, compared to the infected and non-treated control that had the highest DSI of 70.0%.
