Abstract:

Survey conducted during the year 2016 and 2017 at three stage of crop growth of onion in four districts of the Kashmir valley revealed the prevalence of disease in all onion growing areas of the valley during the month of May and June, while during the month of April prevalence of disease was recorded at only few locations, while as rest of the locations were disease free with overall incidence of 1.70, 28.02 and 60.33 and intensity of 0.30, 5.96 and 36.44 per cent, during the month of April, May and June, respectively. The disease was severe during 2017 with overall mean disease incidence of 1.73 28.27 and 62.74 and intensity of 0.31, 6.06 and 38.12 percent in comparison to 2016 with overall incidence of 1.67, 27.77 and 57.92 and intensity of 0.30, 5.85 and 34.06 percent, during the month of April, May and June, respectively. Perusal of the pooled data of two years revealed that the disease incidence and intensity in surveyed areas varied from 42.90 to 73.48 and 25.31 to 49.36 per cent, respectively with highest incidence and intensity recorded in Anantnag and lowest in Srinagar. Of the 12 locations surveyed, highest disease incidence (90.59%) and intensity (59.86%) was recorded at Chadoora followed by Bijbhera, Sangam, Ompora, Wadura and Larnoo, respectively. Shalimar, Pattan, Achabal and Danderkah recorded the disease parameters to moderate levels. Least incidence (27.20%) and intensity (16.17%) was recorded at Noorbagh (Srinagar).
