Mungbean (Vigna radiata (L.) Wilczek) plants showed light-colored,
irregular spots of variable size which soon turned white with narrow
reddish-brown margins. Under severe infection, premature defoliation occurred.
The fungus was identified as Rhizoctonia solani Kuhn. There does not appear to
be any previous record of R. solani Kuhn causing web blight of mungbean in
Pakistan. [AS/EMS]

Rhizoctonia bataticola was observed to cause a wilt of Vigna mungo, Arachis
hypogaea, and Hibiscus cannabinus. A pycnidial stage of this fungus
(Macrophomina phaseoli) occurred on all these hosts and the interrelationship
between these two forms was established in cultures. [EMSI

Internal boll disease in the cotton belt of South Africa is caused in the
first instance by micro-organisms, amongst which Nematospora gossypii is the
most important, whilst N. coryli also occurs. The incidence of these two fungi
is associated with the punctures of the indigenous species of stainers, which
probably act as carriers of infection. Other hosts of Nematospora include beans
of several varieties, including kidneybean, soybean and mungbean, Bauhinia
Galpini and Sterculia platanifolia. [ASJ

Mungbean seed treated with Phygon, Arasan, Dow 9B, and Spergon responded
significantly to the treatment, with Phygon at all dosages being most effective
and yiclding plants that were taller than seedlings from seed treated with
other chemicals. Nodulation was not inhibited by chemical treatment of seed of
alfalfa, mungbean, yellow hop clover, Chinese red cowpea, hairy vetch, and
Austrian winter pea, when chemical treatment was followed by seed inoculation
with "Nitragin" bacterial inoculum. [AS/EMSj
