carbendazim, benomyl, thiophanate-methyl, dichlozoline and Ohric gave 80-90%
control of damping-off of mungbean seedlings. A single soil drench with
thiophanate-methyl and two drenches with benomyl gave about 90% disease
control. More seedlings with R. solani infection survived when
thiophanate-methyl was used as a post-inoculation soil drench than when benomyl
or chloroneb were used. [AS]

Uptake of benomyl by germinating seeds and its subsequent translocation to
roots, stems and leaves of blackgram (Vigna mungo) was studied by bioassay
method using Rhizoctonia solani as the test organism. The fungitoxicant, when
used as a seed treatment, first accumulated in a short time in the seed coat
and then moved into the cotyledons. Later on the chemical was found in the
roots, stems and leaves, maximum accumulation being in roots followed by stems
and leaves. [AS]

Blackgram, lablab bean and kidney bean were seriously affected by a collar
rot disease during 1970-71. The pathogens isolated were identified as
Rhizoctonia solani Kuhn. Further, the isolates were inoculated to Vigna mungo,
Dolichos lablab, D. biflorus, Phaseolus vulgaris, V. radiata, Cicer arietinum,
Glycine max, V. sinensis and Cajanus cajan. Though the isolates of R. solani
produced similar diseases, there were some differences in the sclerotial size,
number per unit area and also in pathogenicity. Among the host plants tested,
V. radiata, V. sinensis, G. max and C. cajan are new hosts for this fungus.

Sclerotium rolfsii phosphatidase B was purified 100 fold by ammonium
sulfate fractionation and DEAE cellulose chromatography. The purified enzyme
was able to induce electrolyte leakage from mungbean hypocotyls. [AS]

Two hours' exposure of mungbean seeds to an inoculum of Rhizoctonia solani
Kuhn caused marked increases in phosphorylase and glutamate dehydrogenase
activities in the cell-free extracts from inoculated seeds. Thereafter, the
differences between the extracts from healthy and diseased mungbean seedlings
in the activities of these two enzymes gradually diminished. In contrast,
