differentiation of Phytophthora vignae isolates from cowpea and adzuki bean.
PHYTOPATHOLOGICAL SOCIETY OF JAPAN, ANNALS, v.52(4):577-584. [En] [En Ja Abst]
(A:PS)
The pathogenicity of 17 isolates of Phytophthora vignae Purss from
Phaseolus radiata var. aurea [Vigna radiata] and 4 isolates from cowpeas was
compared. Isolates from V. radiata were virulent to V. radiata, but not to
cowpeas, while isolates from cowpeas were virulent to cowpeas, but not to V.
radiata. The soluble proteins and isoenzymes patterns of these isolates,
compared by zone electrophoresis, showed no qualitative differences between V.
radiata and cowpea isolates. Although the pathogens of both V. radiata and
cowpeas have been treated as P. vignae, two formae specialis are proposed for
these two fungi on the basis of their specific pathogenicity: P. vignae f.sp.
adzukicola Tsuchiya, Yanagawa et Ogoshi for the former and P. vignae f.sp.
vignae Tsuchiya, Yanagawa et Ogoshi for the latter. Furthermore, from
differences in pathogenicity to six cultivars of V. radiata, three races (1, 2
and 3) were recognized within f.sp. adzukicola. [AS/THH]

Six fungicides were tested against rust of blackgram - Uromyces
appendiculatus. Only one spraying was given at 45th day after sow.ng. All
fungicides reduced the disease incidence; they were, in order of decreasing
efficacy: sulfur dust, Benlate, E.L. 273, thiram, Vitavax, and wettable sulfur.

[En Abstj (REP.MB-2401)
The symptoms and causal fungus of rust on mungbean [Vigna radiata (L.)
Wilczek] in the Philippines are described. The disease is characterized by the
presence on the leaves of lesions that are pinhead in size and are cinnamon
brown due to the uredinia of the pathogen, Uromyces vignae Barcl. Each lesion
is usually surrounded by a yellow halo. Severely infected leaves often dry up
prematurely and fall off. [AS]
