Investigations were conducted at CIAT to develop methodology required to evaluate resistance to Isariopsis griseola inherent in bean germplasm and breeding progeny. Abundant sporulation by the pathogen has been achieved by growing isolates in the lab. on V-8 medium incubated at 19 degrees Celsius...

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...


Garrett, K.A.Schwartz, Howard F.[Research on pseudomonas bacterial epiphytes in Colorado]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...

More than 60 accessions of tepary bean (Phaseolus acutifolius) and five cultivars of common bean (P. vulgaris) were evaluated for disease reactions to different races of wilt-causing Fusarium (F. oxysporum f. sp. phaseoli) under glasshouse conditions; 95% of the tepary accessions were resistant. ...
