The wilt disease of ginger plant caused by Pseudomonas solanacearum is the main problem on the cultivated plant caused the losses yield up to 75 percent in the centre production area in Bengkulu. The experiment of using coffee leaf mulch and bacterial antagonist (P. fluorescens) was conducted in Sukarami, Curup District, Bengkulu Province from May to December 1999. Treatment were coffee leaf mulch, bacterial antagonist and farmer method used agrimycine as the controlled treatment. Treatments were arranged in randomized completely block design (RBD) with six replications. The observation were the percentage of infected plant (early and last observation), plant growth (the height of plant and shoot number) and production in five months old. The result showed that the coffee leaf mulch and bacterial antagonist were effective to control the disease with the infected plant were 2.72 and 3.75 percent, respectively at five months old. However the agrimycine treatment was not effective to control the disease with infected plant was 47.00 percent. In addition, both mulch and antagonist treatment could increase the plant growth indirectly with the percentage of high plant growth were 11.22 percent and 6.59 percent separately, the shoot number were 86.27 and 33.58 percent and the yield were 77.92 and 47.40 percent
