Cercospora leaf spots and leaf reddening of mungbean. INDIAN JOURNAL OF
MYCOLOGY AND PLANT PATHOLOGY, v.10(2):78-79. [En] (REP.MB-2302)
Five chemicals were tried for 3 years to develop a common spraying schedule
for the control of Cercospora leaf spot (Cercospora canescens), bacterial leaf
spot (Xanthomonas phaseoli) and leaf reddening of mungbean. Bavistin was highly
effective for the control of all three leaf diseases. It completely controlled
Cercospora leaf spot and leaf reddening. However, for the control of bacterial
leaf spot, blitox and streptocyline also showed very promising results. [THH]

Macrophomina phaseolina isolates causing root rot and leaf blight of uridbean.
INDIAN PHYTOPATHOLOGY, v.34(4):407-409. tEni [En Absti (A:PS)
Differences between two Macrophomina phaseolina isolates, one causing root
rot and another leaf blight in blackgram (Vigna mungo (L.) Hepper) were
studied. The root rot isolate grew more profusely in blackgram hypocotyl
extract medium while the leaf blight isolate preferred the host leaf extract
medium. Both the isolates produced various pectolytic and cellulolytic enzymes
both in vitro and in vivo. Glucose increased polygalacturonate trans eliminase
production by the root rot isolate and decreased the enzyme production by the
leaf blight isolate. IASJ

(A:PS)
To determine the minimal fungicide concentration and spraying frequency for
effective control of Cercospora leaf spot and powdery mildew of mungbean with
Carbendazim, the fungicide was sprayed either once or twice in concentrations
ranging from 12.5 to 250 g a.i./ha. One spray with 125 and 62.5 g a.i./ha or
two sprays with 62.5, 50 and 25 g a.i./ha resulted in the highest yields. Two
sprays at still higher doses gave significantly lower yields than the lower
doses. [EMSJ

Six fungicides, viz., Bavistin, Calixin, Karathane, Morocide, Dithane M-45
and Sulfex, sprayed repeatedly at 10 days interval, were evaluated for control
of powdery mildew (Erysiphe polygoni) and leaf blight (Macrophomina phaseoli)
of mungbean. All fungicides were significantly superior to the check in
controlling the diseases. Maximum disease control as well as grain yield were
recorded with Bavitin. [EMS]
