The opium poppy is one of important medicinal plant. Morphine, Codeine and Thebaine alkaloids are the products that are prepared from it. The crop is damaged by a number of fungal diseases, which causes heavy losses. An experiment was designed to evaluate the efficacy of few chemical fungicides and biofungicides, cow urine, buttermilk and botanicals against downy mildew of Opium poppy. Downy mildew (DM) caused by Peronospora arborescens, is a serious disease in Opium poppy (Papaver somniferum L.), which has a world-wide spread. Minimum disease incidence 10.12 per cent was recorded in T6 (Seed treatment and three foliar spray of Ridomyl MZ) followed by 14.21 in T5 (Seed treatment and three foliar spray of Mancozeb @ 0.25 per cent), Maximum reduction (83.82 per cent) in disease intensity was found in T6 followed by T5 (77.30%).The untreated plot showed high disease intensity (62.58 per cent) Maximum latex yield (kg/ha) was found in T6 (40.15 kg/ha) followed by T5 (38.33 kg/ha.) and in control plot it was found minimum, 30.98 kg/ha, Similar to latex yield the maximum seed yield (13.83 q/ha) was found in T6 followed by T5 (12.3 q/ha). The minimum seed yield was found in control plot 9.5q/ha. The use of plant products and 7 days old buttermilk and fresh cow urine were not associated with any health hazards and environmental and soil pollution. These plant product, have not received yet commercial attention, However botanicals and cow urine and buttermilk significantly reduced disease incidence as well as increase the yield.
