C. canescens. In media containing any of the isolated compounds, the hyphal
strands became shorter and wider and abnormal structures such as lobed tip,
crooked strand and deformed hyphal branch were noted. In mycelial growth assay,
smaller radial growth and lesser pigmentation and density of the colony were
observed. The increasing order of magnitude of effects of compounds 1 or 4, 2
and 3 suggests that compound 3 is the main inhibitory compound of the resistant
varieties studied. [AS]

The fungicidal experiment was conducted against Cercospora leaf spot of
mungbean. The chemicals were applied twice at fortnightly intervals. The first
spray was done at first appearance of the disease. Bavistin + Dithane M-45,
Bavistin and Benlate significantly reduced the disease, and increased yield
over the untreated control. Bavistin and Benlate have been reported to be
effective to foliar diseases of several crops under Indian condition. [THHJ

The pathogen, Drechslera halodes, was found to be sensitive to Thiram,
Cuman liquid, ferbam, zineb, captan and Aureofungin in vitro. In pot culture
experiment zineb was found highly effective as foliar spray. Captan,
Aureofungin and Cuman also gave good result. In soil drenching Thiram and
Brassical were found most effective. Mungbean suffers great loss due to a leaf
spot disease caused by Drechslera halodes. LASJ

The leaf spot disease of mungbean caused by Drechslera halodes was soil
borne and perpetuated through diseased plant debris from one season to another
under field condition for more than eight months. Survival of the pathogen was
better at low temperature than at higher temperature. The seeds did not play
any role in the primary infection of the disease. The secondary spread of the
disease was through spores produced on diseased leaves and transmitted by air.

Despite severe lodging, the experimental mungbean variety VC 1560A yielded
1900 kg/ha. Yields from King and Berken were substantially less, and were only
slightly improved by fungicide application intended to control Cercospora leaf
spot. [AS]
