Abstract


The application of hull ash, onion and garlic extracts on the soil for ginger plantation infected by Pseudomonas solanacearum.

A pathogen of ginger rhizome rot (bacterial wilt) to persist in the soil and therefore becomes a threat to the following ginger crop. Such problem always arises despite the manipulation of the soil conditions, 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 hust ash or onion extract suppressed the disease intensity on ginger up to months after transplanting. The Agrimicyn could only suppressed the disease up to 44 days after transplanting and the infection intensified rapidly there after to reach a rate of 55%, at the age of 71 days.

These results open an opportunity to growing ginger continuously on the same land provided that the crop is harvested early, at the age of 3 months.
