A pathogen of ginger rhizome rot (bacterial wilt) persists in the soil and therefore become a threat to the following ginger crop. Such problem always arises despite the manipulation of the soil condition, as long as ginger is available as host on the land. A green house trial applying agrimicin, ash of rice husk, extract of onion and garlic was conducted at Balittro (Research Institute for Spices and Medicinal Crops), Bogor, in an effort to minimize the disease intensity. The results showed that the application of rice husk ash or onion extract suppress the disease intensity in ginger up to 3 months after transplanting. Agrimicin could only suppress the disease up to 44 days after transplanting and the infection intensified rapidly thereafter to reach a rate of 55 percent at the age of 71 days. These results open an opportunity to growing ginger continuously in the same land provided that the crop is harvested early at the age of 3 months.
