powdery fildew (Erysiphe polygoni DC) of green gram (Vigna radiata (L.)
Wilczek). PESTICIDES, v.16(8):10-11. [En] (REP.MB-2552)
All eight fungicides tested, when sprayed three times at 8-day intervals,
gave very effective (90-100%) control of powdery mildew. Yield increases over
the control were as follows: 172% (Sulphur dust), 141% (Sulphen - 80), 114%
(Nimrod), 82% (Sultaf), 69% (Morestan), 54% (Wettasul), 48% (Sulfavit), and 25%
(Karathane). [EMS]

A field trial on the effect of fungicide wetsulf (0.3%) against powdery
mildew (Erysiphe polygoni) in blackgram was conducted. Increasing the number of
sprays resulted in a decrease in the disease incidence. Three and two sprays
increased yields 55% and 45%, respectively, over the unsprayed control. A
spraying schedule of 3 sprays at 12-day intervals is recommended. [THH]

The powdery mildew disease of blackgram (Vigna mungo Hepper) and mungbean
(Vigna radiata Wilczek) caused by Erysiphe polygoni DC was found to be
effectively controlled in vitro by Karathane, wettable sulphur, Sulfex and
Benlate. But Bavistin, wettable sulphur, Karathane, Sulfex and Benlate were
highly effective in controlling the disease under field conditions. Dithane
Z-78 was also effective in controlling the disease in field conditions. [AS]

infection on the nitrogen metabolism of blackgram. MADRAS AGRICULTURAL
JOURNAL, v.70(5):316-318. [En] [En Abstj (A:PS)
Changes in the total nitrogen and amino acid content of the infected leaves
along with the protein content of the grain in the pods were studied. There was
an overall increase in the total nitrogen and free amino acid contents of the
infected leaves while the protein content of the infected grains in the pods
decreased with increased intensity of infection. [AS]

Benlate, sulphur dust and wettable sulphur controlled the powdery mildew of
blackgram (Vigna mungo (L.) Hepper) better than other chemicals. Application of
sulphur dust and wettable sulphur brought about an increase in yield by 47.3
and 45.9%, respectively, and resulted a net profit of Rs. 200 and 187 per ha,
respectively, over the control. [AS]
