Title : Participatory Idm Research on Potato Late Blight Through Farmers field school Material Type: printed text Authors: Sharma, B.P., Author ; H. B. K. C, Author Pagination: 205-210 p. Languages : English (eng) Keywords: cost analysis, empowerment, IDM, late blight, participatory research Abstract: Late blight caused by Phytophthora itifestans (Mom.) DeBary is the most devastating disease
of potato causing substantial yield loss in the country. Various agro-inputs are being
advertised and made available to the farmers for the control of late blight. Farmer's Field
School (FFS) has been under way since 1998 in the Kathmandu valley to empower the potato
fanners for profitable technology and input selection with great emphasis on integrated
disease management (/DM) assess in terms of cost effectiveness against late blight. FFS
conducted during Jan-April 2003 at Mulpani-2 Kathmandu, revealed that participated
farmers became able to select technology and inputs as per cost effectiveness and their
requirements. The outstanding experiences of FFS were (I) Variety Khumal Seto-1 was
unanimously selected for higher yield (31.44 tlha) with late blight resistance. (2) Farmers
convinced themselves to grow spring season potato without fungicides spray (3) Farmers
realized that use of "EM"(essential microorganism) and "Magic" (concentrated natural
seaweed fertilizer) spray on potato increased tuber yield but not found cost effective. (4)
Application of Trichoderma harzianum (NIP ROT) was not found effective for late blight
control. (5) Commercial adjuvant (APSA-80), when added into spray solution, was found to
be quite effective to increase the efficacy of fungicide. IDM applied plot produced 34-47 %
more tuber yield than existing farmers practice. Farmers were empowered for technology and
input selection based on per unit cost of production.Link for e-copy: http://elibrary.narc.gov.np/?r=494 Participatory Idm Research on Potato Late Blight Through Farmers field school [printed text] / Sharma, B.P., Author ; H. B. K. C, Author . - [s.d.] . - 205-210 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.Link for e-copy: http://elibrary.narc.gov.np/?r=62

Languages : English (eng) Keywords: late blight, participatory, potato cultivars, tuber yield Abstract: Farmers' participatory multi location field experiments were conducted in 201 Ill 2 with the objectives
of evaluating late blight disease [Phytophthora infestans (Mont) de Barry] resistant and high yielding
potato genotypes. Twenty hvo promising potato genotypes which have been selected through the series
of experiments since 2006, were tested in farmers' fields at Dhikure (Nuwakot), Panvanipur (Bara),
Belachapi (Dhanusa), Sonpur (Dang) and Kimugaun (Dailekh) involving twa to four farmers in each
location. A farmer's field trial ~FF.I') set per farmer, composed af6-15 genotypes, were planted in the
plat size ranging from 3 to 6 m during the respective potato planting season. Potato cultivars Desiree
and Kufri Sindhuri in Bara, Lalgulab in Dhanusa, MS-42.3 and Cardinal in Nuwakat and Tharu Local
in Dang were used as check to compare with test genotypes. Fungicide against any disease was not
sprayed throughout the crop period Late blight severity as foliage damage % was recorc(ed at 70-75
days after planting. Crop was harvested at 90-110 days after planting depending an the location and
farmers decision. Genotype PRP-266264.01 produced the highest tuber yield (46.67tlha)followed by
PRP-266264.15 (41.67 tlha) in Dang, LBr-40 (37.17 t/ha) and CIP-384321.15 (31.83 tlha) in

Languages : English (eng) Keywords: Clones, late blight, potato, resistant, yield Abstract: A field experiment-was carried out at RARS Parwanipur during 2003 and 2004 to
evaluate the potato clones. Plant emergence, uniformity and percent ground foliage
were significantly higher at clone 393280.64. Plant height was measured highest
(58.7 em) in clone 392637.10 and highest number of stems per plant (3.6) in clone
393385.39. Clones 385556.4 and 393077. 159 were found resistant to late blight
whereas clones 392657.8, 393280.64 and 392637.10 were tolerant to late blight. With
respect to total and marketable tuber yield, six potato clones were produced
significantly higher tuber yield as compared to check varieties. Based on the evaluation
parameters, late blight infection, tuber yield and agronomic characters, clones
388556.4, 392657.8, 392280.64, 392637.10, 393077.159 and 393385.39 were
