## Abstract
Abstract Trichoderma asperellum is a potential biocontrol agent against vascular streak dieback disease (VSD) on cocoa. In this research, we evaluated the suppress capacity of the fungus combined with composted plant residues against the VSD disease on five cocoa clones: S1, MCC 02, AP, THR, and RB. According to VSD development observed in six months, Sulawesi 1 was considered as less sensitive, MCC 02 was moderate resistant, AP was resistant, THR was susceptible, and RB was moderate resistant. The disease incidence on these five clones was 32.9%, 31.0%, 27.9%, 39.9%, and 26.6%, respectively three months post-application and each of this incidence were significantly different (p ≤ 0.05) with the control. While, the efficacy of application was 60.1%, 55.2%, 49.9%, 75.6%, and 37,6%, respectively. These data indicated that capability of T. asperellum in suppressing VSD disease depends on the clone and lowest on the resistant clone.
