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...
Epidemiology of bean (Phaseolus vulgaris) web blight (BWB) caused by Thanatephorus cucumeris (teleomorph of Rhizoctonia solani) was studied in a field with a history of severe incidence of the disease. Sclerotia and mycelium of T. cucumeris, either free in soil or in the form of colonized debris,...
Nineteen early maturing, indeterminate common bean parents were crossed with a tester line of normal maturity. All parents, F1 hybrids, F2's, and backcross generations were evaluated at CIAT-Palmira, Colombia. All 19F1 populations flowered and matured almost as early as the respective early paren...
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...
