Abstract
This study examined the effect of the addition of Beauvaria bassiana on the effectiveness of Nicotiana tabacum extract as a biopesticide against coffee berry borer (CBB) or Hypothenemus hampei. A six months field experiment was carried out to examine the combined biopesticide effect on robusta coffee plantation. Randomized complete block design (RCBD) was used as a model for this experiment that consists of two factors. The first factor was the composition of Beauveria bassiana in water (0 to 320 g), while the second factor was Nicotiana tabacum extract composition in water (10 to 30 mL). The results showed that the dosage of Beauveria bassiana had a significant effect on tobacco biopesticide extract on the percentage and the intensity of CBB attacks. The combination of 320 g Beauveria bassiana /8 L of water and 30 mL Nicotiana tabacum extract/10 L of water, in our experiments (B4T3) could reduce the percentage and intensity of coffee fruit attacked by CBB to 1.54% and 0.33%, respectively.
