Within the project "Development of an integrated management of diseases of cacao with emphasis onbiological control", it aims to determine the level of optimization for mulations combining biocontrol agents for the management ofdiseases of cocoa. Both Moniliophthoraroreri (Cif and Par) as Moniliophthorapernicious (Aime andPhillips-Mora) are important pathogens that caused etriment to the productivity of cacao. Afriendly alternative environment is the use of Biological Control Agents (BCA). The evaluations were conducted in two seasons (June and January). Was used pods (about three months) both Trinitarian (ICS – 96 and CCN 51) as National (EET – 233 and EET-103). Plant antagonists were (Trichodermakoningiopsis 4.09 and T.ovalisporum 70a). Asinoculumvehicle were used five types of vegetable oil (corn, soybean, palm, sunflower and agricultural). Significant differences for the treatments were presented. The highest percentages of colonization in the early days of assessment were recorded for the treatment ICS -96 +Tk 4.09+agricultural oil with 86% (epiphytic) and ICS-96 +Tk 4.09+ Sunflower oil with 88% (endophytic). The lowest percentages were recorded for EET- 233 +To 70a+18% Oil agricultural and EET-233 +To 70a+Sunflower oil with 6%, epiphytic and endophytic respectively action. In the second epoch of the highest expressions evaluation presented them both in epiphytic 100% and endophytic 96% is treatment ICS – 96 + To 70a+soybean oil; the lowest percentages were recorded for EET– 233 + To70a+Soybean oil with 8% (epiphytic) and EET– 233 + To70a+Sunflower oil with 0% (endophytic). The plant material factor(Trinitarian and National) has high significance in the expression of either in oculum BCA vehicle.
