A leaf spot of mungbean caused by Alternaria alternata (-A. tenuis), wa3
found in September 1969 at the Udaipur, Rajasthan, India. Eighty percent of the
plants were infected. It was estimated that 45% of the leaf area showed brown
lesions. This appears to be a new record for this leaf spot on mungbean. [THH]

Mungbean yield was reduced due to Cercospora leaf spot by 23% when 75% of
the foliage was killed. Timely spraying of Benlate can delay the rate of
development and spread of Cercospora leaf spot and thus prevent yield losses.

Protomycopsis patelii Pavgi and Thirumalachar causing angular black spot of
Vigna mungo and V. radiata, and Protomycopsis thirumalacharii Pavgi causing
purple leaf spot of Sesbania grandiflora Pers. are perpetuated from one season
to another through desiccated but viable, heat-resistant chlamydospores in the
host residue and those developed in vitro in the soil. The heat-resistant
mycelium is later consumed in forming the resting chlamydospores in the soil,
thus adding another dimension to the initial soil-borne inoculum potential of
the disease. [AS]

A leaf spot disease of blackgram was shown to be due to Sclerotium rolfsii.
Four cultivars out of 21 tested were resistant to the disease. [EMS]
