Among the bacterial diseases that attack beans are (1) halo blight (Pseudomonas phaseolicola), which is distributed worldwide and survives in infected seeds and blunt residue. Three to five days after infection, water-soaked spots appear on the lower leaf surface, stem and pods; (2) bacterial wil...
Entre las enfermedades bacterianas que atacan el frijol tenemos: 1) anublo de halo (Pseudomonas phaseolicola) que se encuentra presente en todo el mundo, sobrevive en semillas infectadas y en residuos vegetales de los 3-5 dias despues de la infeccion aparecen manchas acuosas en el enves de la hoj...
Bean plants are exposed to many fungal diseases; among these are: Alternaria and Ascochyta leaf and pod spots, ashy stem blight (Macrophomina phaseoli), Cercospora leaf spot, Chaetoseptoria leaf spot, Diaporthe pod blight, downy mildew (Phytophthora parasitica), Entyloma leaf smut, floury leaf sp...

Effects of sub-lethal applications of propiconazole on bean rust
In 1986, 5 commercial bean sites near Holyoke (Colorado, USA) were treated with 4 sprays of cupric hydroxide every 7 to 10 days beginning at least 2 wk. before flowering to (1) sample for the presence of Cu resistance in naturally-occurring epiphytic populations of Pseudomonas syringae pv. syring...

Research on pseudomonas bacterial epiphytes in Colorado
Investigations during 1984 and 1985 demonstrated that Pseudomonas syringae pv. phaseolicola (Psp) and Pseudomonas syringae pv. syringae (Pss) occur as epiphytes on dry beans in Colorado. Populations of syringae-type pseudomonads (STPs) were detected on volunteer bean plants throughout northeaster...

Sources and management of Pseudomonas syringae pv. phaseolicola and Pseudomonas syringae pv. syringae Epiphytes on dry beans in Colorado
Results of the research on beans carried out by the Dept. of Plant Pathology and Weed Science of Colorado State U. (USA) are briefly summarized. Surveys in the spring of 1984 and 1985 found many wild beans infected with, and/or colonized by, populations of Pseudomonas syringae pv. phaseolicola an...
