Journal of Phytopathology, 162(10), 697-702. doi: 10.1111/jph.12233 There are instances when small growers (those who cultivate 3 to 5 hectares) have sustained as high as 70 to 80 percent plant losses due to Moko.

Nipah) in Malaysia. In the initial stages the bacterial wilt is characterised by the yellowish discolouration of the inner leaf lamina close to the petiole.

The spread of the pathogen from tree to tree or between fields can occur in many ways. Fusarium oxysporum. IPM for Banana. Moko disease is a bacterial wilt caused by Ralstonia solanacearum invading the vascular tissues of hosts. High temperatures and high soil moisture generally favor the disease. is caused by R. solanacearum strains which belong to phylotype II of the R. solanacearum species complex (Fegan and Prior, 2006). Moko disease produces dramatic symptoms of wilt, dieback and death of banana and plantain. The disease constitutes a major phytosanitary problem in plantain and banana crops, causing production losses, high eradication costs, and plant quarantines. A clear, pale yellow to brown discoloration is visible in the vascular region when they are cut open.

Many strains have less than 70% DNA-DNA homology, which has been considered a threshold level within a species. Take care not to damage the plants during field work. Fegan & Prior (2005) proposed a hierarchical classification for R. solanacearum, based on phylogenetic analysis of 16S-23S ITS and endoglucanase gene sequences, where race 2 strains belong to Phylotype II, sequevars 3, 4 and 6. Bacterial Wilt or Moko Disease (Common Banana Farming Diseases Symptoms) (Pseudomonas solanacearum) The young plants are affected severely. Race 2 occurs mainly in tropical areas from South and Central America causing moko and in the Philippines, causing bugtok disease. Ralstonia solanacearum is a species complex with exceptional diversity amongst strains from different hosts and geographical origins. Spread 10 % fresh cow dung slurry in the plant basin.
