Abstract:
Indian mustard [Brassica juncea (L.) Czern & Coss] is an important edible oilseed crop in India. The production of oilseed brassicas, second largest oilseed crops grown in the world, is gravely hampered by the fungal diseases; Alternaria blight being one of the most ravaging fungal diseases. The pseudo-fungi, not only leads to yield reduction by causing foliar damage to the crop, but also severely deteriorates the oil quality. In this present investigation to evaluate nine homeopathic drugs viz., Cina, Borex, Selenium, Nux Vomica, Siliciea, Sulphur, Phosphorus, Arnica montana and Calcarea carbonicum at two concentrations (500 and 1000 ppm) against Alternariabrassicae and mycelial growth was recorded at 7 days after inoculation. All the tested homeopathic drugs significantly inhibited the mycelial growth of A. brassicaeat the concentration of 500 and 1000 ppm but none of these drugs could completely inhibited the growth even at 1000 ppm. At 500 ppm, the minimum mycelium growth was obtained in Sulphur (43.67 mm) followed by Siliciea (46.00 mm), Cina (51.00 mm), Nux vomica (54.67 mm), Selenium (57.67 mm), Phosphorous (59.33 mm), Borex (62.33 mm), Arnica montana (64.33 mm) and Calcarea carbonicum (67.00 mm), while maximum mycelial growth was recorded in control (89.00 mm). Sulphur was found most effective at 1000 ppm (13.33 mm) followed by Siliciea (15.00 mm), Cina (21.00 mm), Nux vomica (23.67 mm), Selenium (26.67 mm), phosphorous (28.00 mm), Borex (30.33 mm), Arnica montana (34.67 mm) and Calcarea carbonicum (36.67 mm), while maximum mycelial growth was recorded in control (90.00 mm).
