Anthracnose is an important disease on chili pepper caused by Colletotrichum sp.. The pathogen can attack from early stage of fruit until harvesting. The losses due to this disease ranging from 40-80%, and even up to 100%. Plant Growth Promoting Rhizobacteria (PGPR) is a group of bacteria which growth and colonize arround roots area (rhizosphere), that has some beneficial effects in plant, such as growth promoting and as biological control agent. The purpose of this research was to determine the effectiveness of PGPR consisting of Pseudomonas fluorescens and Bacillus polymixa, combined with micronutrients MnSO4 0.05%, ZnSO4 0.05%, MnSO4 0.05%+ ZnSO4 0.05%, and commercial fertilizer Growmore 10-55-10, to suppress anthracnose disease on chili pepper. This experiment used a Randomized Block Design (RBD) with 6 treatments and 3 blocks. Variables measured were seed germination, plant height, number of leaves, and the severity of anthracnose disease. The results showed that the treatments with PGPR and or combined with micronutrients could not suppress the disease severity comparing with conventional control measure. Combining with micronutrients (MnSO4) increased the PGPR capability on plant growth promoting effects.
