Identification of best spray schedules for propiconazole fungicide against spot blotch disease in wheat / Bhandari, D.    

Public ISBD in Proceedings of the 28th National Winter Crops Workshops held at Lumle, 9-10 March 2011 / Giri, Y.P.     Title : Identification of best spray schedules for propiconazole fungicide against spot blotch disease in wheat Material Type: printed text Authors: Bhandari, D., Author Pagination: 314-319 p. Languages : English (eng) Keywords: AUDPC,  Cost  Effectiveness,  Propiconazole,  Spot  Blotch,  Spray,  Wheat Abstract: Spot blotch disease caused by Bipolaris sorokiniana (Sacc.) shoem. is one of the most destructive diseases of wheat ( Triticum aestivum L.) in plain areas of Nepal. Triazoles fungicides are expensive but effective against the disease. The experiment was conducted to identify the most efficient spray schedules of Tilt (Propiconazole 25 ec) fungicide against spot blotch disease in wheat. The experiment was carried out at National Wheat Research Program, Bhairahawa, Nepal in Randomized Complete Block Design with three replications and 12 treatments..............

Economic Management of Late Blight (Phytophthora infestans L.) of Potato in Eastern Tarai of Nepal / Prem C.P. Chaurasia in Nepal Agriculture Research Journal, Vol. 6 (2005)  

Public ISBD [article]  inNepal Agriculture Research Journal > Vol. 6 (2005) . - 57-61 p Title : Economic Management of Late Blight (Phytophthora infestans L.) of Potato in Eastern Tarai of Nepal Material Type: printed text Authors: Prem C.P. Chaurasia, Author Publication Date: 2005 Article on page: 57-61 p Languages : English (eng) Keywords: Eastern  Tarai,  economic  spray,  Dithane  M-45,  late  blight  management,  potato Abstract: Field experiments were carried out at Regional Agriculture Research Station, Tarahara in three consecutive years (1997-2000) during winter season to know the economic sprays of different fungicides to manage late blight disease of potato. Late blight susceptible cultivar of potato Kufri Sindhuri was used for the experiment. Krinoxyl gold (metalaxyl 8% and mancozeb 64%) at the rate of 1.5 g/l, Dithane M- 45 (mancozeb 75%) @ 0.3% and Bordeaux mixture @ 10 g copper sulfate and 10 g lime/l of water and their different combinations were tested in randomized complete block design with three replications. Terminal disease severity was the highest (7.9) on 0-9 scale disease rating in unsprayed check and it was significantly higher than those of other fungicides sprays. Plots with three sprays of Dithane M- 45 @ 0.3% recorded the lowest (2.4) terminal disease severity. Disease development was the fastest in the unsprayed plot compared to all other treatments. Similarly apparent infection rate was the highest in unsprayed treatment. Area Under the Disease Progress Curve was also the highest in unsprayed plot and it was significantly higher than those of other treatments. Tuber yield was the lowest (3.93 kg/4.5 m2 plot in unsprayed and the highest (6.08 kg), in the plot receiving four sprays of Dithane M-45 @ 0.3 % and this was at par with the tuber yield of plots receiving two and three sprays of Dithane M-45. Benefit cost ratio was the highest (1.54) in case of two sprays of Dithane M-45 @ 0.3% at 10 days intervals. All others fungicide spays were uneconomical under Eastern Tarai condition.
