disease recorded from Assam. INDIAN PHYTOPATHOLOGY, v.29(i):61-62. [En]
(REP.MB-1739)
A serious disease of mungbean was observed in the experimental fields of
the Assam Agricultural Univ. and was identified as Corticium sasakil (Shirai)
Matsumoto L=Thanatephorus cucumeris (Frank) Donkj. The disease symptoms are
described. [EMS]

[En] (REP.MB-2187)
Root rot or maturity wilt caused by Macrophomina phaseoli is the most
serious disease in blackgram. A severe leaf blight disease occurred in Tamil
Nadu during 1974-75. Macrophomina phaseoli was identified as the causal agent.
The present studies showed the presence of two entirely different strains of M.
phaseoli, one attacking roots and the other attacking aerial parts. [THHJ

Rhizoctonia bataticola leaf blight of mung bean. INDIAN PHYTOPATHOLOGY,
v.34(I):24-29. [En] [En AbstJ (A:PS)
Rhizoctonia bataticola caused a severe blight of mungbean (Vigna radiata)
foliage at 30-35 C when 4-8 days old inoculum was used and inoculated plants
were kept for 8-24 h at high humidity. Roots and collar regions could be
infected artificially by the foliage isolate. No cultivar or advance line was
found resistant. On mungbean R. bataticola isolates from sesamum and castor
were more aggressive than groundnut isolate. Host range of the pathogen was
restricted. It was externally seed borne. [AS]

of black gram and its effect in some varieties. CURRENT RESEARCH (UNIVERSITY

Symptoms caused by Macrophomina phaseoli on blackgram are described. Ten
blackgram cultivars were evaluated for their reaction to the pathogen.
Cultivars with the lowest disease severity were K-3, PH-25, K-878, and T-9.
Reduction in numbers of pods/plant ranged from 4.1 to 52.2% (av., 22.9%) and in
100-seed weight from 3.5 to 11.4% (av., 7.8%). Although the incidence on 3
cultivars (K-878, K-3 and T-9) was low, reduction in pods/plant was high
because they were infected at an early stage. Variation in the performance of
blackgram cultivars in different locations suggests the existence of distinct
physiologic races. [THHJ
