Bacterial pod rot of Leucaena leucocephala caused by Pseudomonas fluorescens Biotype 2
During 1980 and 1981, a severe pod rot was found on the forage browse legume Leucaena leucocephala in Belize, Brazil, Mexico and Panama. The causal bacterium was identified as Pseudomonas fluorescens Biotype 2. Kock's postulates were successfully completed with four isolates. The constant association of lesions with insect feeding holes indicates that the bacterium is insect-borne. Cross-inoculation studies showed that L. diversifolia and L. shannoni are not as susceptible to the disease as L. esculenta, L. leucocephala and L. pulverulenta. Further studies are needed to understand the insect-bacterium association and to qualify the effect of the bacterium on seed production. This is the first report of bacterial pod rot of L. leucocephala. (EN)
