Title : Evaluation of maize varieties against grey leaf (GLS) disease Material Type: printed text Authors: ASR Bajracharya, Editor ; D.L. Mandal, Author ; Chaudhary, R.N., Author Pagination: 322-325 p. Keywords: Cercospora zeae-maydis ; GLS Abstract: Maize grey leaf spot (GLS) caused by Cercospora zeae- maydis Tehon & Daniels causes
grain yield loss up to I 00 percent. Resistant varieties offer the best option for economic
control of the disease in Nepalese hill maize farming context. Considering the fact, released
maize varieties for mid and high hills along with some varieties from CIMMYT were
evaluated against the diseases at Pakhribas (1750 mas!) during 2009 and 2010 in RCB
design with two replications. The varieties included were Zm-627, Zm-525 and
Zm07SADVI (from CJMMYT) and Sheetal, Deuti, Ganesh-1, Mankamana-1,
Manakamana-3, Manakamana-4, Manakamna-6, Poshilo Makai-1 (released varieties) and
Farmers' local as check. Scoring was done three times on 1-5 scale given by Saghai and
Maroo (1993). The experiments conducted during 2009 and 2010 rainy season revealed that
genotypes Zm-627, Zm-525 and Zm07SADVJ were least affected by the diseases during
both the years. Recommended varieties Sheetala, Deuti and Ganesh-1 performed better than
local check in both years. Whereas, Mankamana-3, Mankamana-6, Poshilo Makai-1,
Mankamana-4 and Mankamana-1 were less affected by the disease as compared to local
check during 2010 but were more affected than local during 2009. On the basis of yield,
Ganesh-1 performed best during 2009 and Zm-07SADVI was best during 201 0.
Manakamana-1 and Manakamana-3 were worst yielder on GLS affected conditions whereas
other varieties were better than farmers' local. Per cent ear rot at the time of harvest was
minimum in farmers' local (2.38%) followed by Mankamana-3 (5.56%) and Ganesh-1
(5 .88%). Per cent ear rot in other varieties ranged between 11- 26%. Per cent ear rot at the
time of harvest fotmd to increase with increase in open cob percentage.Link for e-copy: http://elibrary.narc.gov.np/?r=962 Evaluation of maize varieties against grey leaf (GLS) disease [printed text] / ASR Bajracharya, Editor ; D.L. Mandal, Author ; Chaudhary, R.N., Author . - [s.d.] . - 322-325 p.

Title : Evaluation of pesticides against grey leaf spot disease of maize in the eastern mid-hills of Nepal Material Type: printed text Authors: N.K Dangal, Editor ; P Joshi ; D.L. Mandal, Author ; Chaudhary, R.N., Author ; Chaudhary, B.N., Author Pagination: 318-321 p. Keywords: Bio-control agent cercospora zeae maydis ; disease severity scory yield Abstract: Grey leaf spot (GLS), caused by Cercospora zeae maydis, is a major disease of maize in the
eastern hills of Nepal. It is also becoming a threat to maize cultivation in the western hills
ofthe country. A field experiment was conducted during 2011 and 2012 in the eastern mid
hills of Nepal to identify the effective pesticides for management of the disease. The
experiment was conducted in Diktel, Khotang at 1400 mas) under natural incidence of grey
leaf spot disease. The experiment was conducted in a randomized complete block design
with 3 replications. Local variety of maize was planted in a plot of 9 m2
• Five pesticides
including bio-control agents were evaluated along with a control (water spray) for their
efficacy in the management of grey leaf spot of maize. The treatments were
Metalaxyi+Mancozeb, Carbendazim, Copper oxychloride, Pseudomonas+ Trichoderma and
Pseudomonas, The pesticideswere applied after the appearance of the disease at silking
stage. Disease scoring was done at 15 days after spraying. Pesticides and bio-control agents
differed significantly in controlling the target disease and producing higher grain yield.
Carbendazim and Metalaxyi+Mancozeb were equally effective in lowering disease severity
(45 .53 and 46.87%). Use of Copper oxychloride (48.33%) was similar to use of
Pseudomonas+Trichoderma (54.17%) in minimizing disease severity. All chemicals and
bio-control agents were superior to control in managing grey leaf spot and producing higher
grain yield. Application of Carbendazim produced the highest grain yield (3.84 tlha)
followed by Metalaxyl+Mancozeb (3.80 tlha) and Copper oxychloride (3.66 t/ha).The
control plot recorded the highest disease severity of 61.53% with production of the lowest
grain yield of 3.03 t/ha. Thus, incidence and severity of the grey leaf spot disease can be
minimized with higher grain production of maize by the use of pesticide Carbendazim in
the disease prone areas of eastern hills.Link for e-copy: http://elibrary.narc.gov.np/?r=961 Evaluation of pesticides against grey leaf spot disease of maize in the eastern mid-hills of Nepal [printed text] / N.K Dangal, Editor ; P Joshi ; D.L.

Keywords: Cercospora zeae maydis ; improved varieties severity scoring yield Abstract: Grey leaf spot, caused by Cercospora zeae maydis, is a major disease of maize in the
eastern hills of Nepal. It has been causing significant maize yield loss in the eastern high
and mid hills, and is also spreading towards the western hills of the country. A field
experiment was conducted during 2011 and 2012 in the eastern mid hills of Nepal to
identify the high yielding GLS resistant maize variety. The experiment was conducted in
Diktel, Khotang at 1400 mas! under natural incidence of grey leaf spot disease. The
experiment was conducted in a randomized complete block design with 3 replications. Plot
size was 9 m2
• Six improved varieties (viz. Ganesh-1, Manakamana-3, Manakamana-4,
Deuti, Sheetala and Posilo makai-1) of maize were evaluated along with the local variety.
Scoring of the disease was done after the incidence of the disease at grain filling stage.
Maize genotypes differed significantly for grey leaf spot severity and grain yield. All the
improved varieties had lower disease severity and produced higher grain yield compared to
the local variety (51.13% disease severity and 3.71 tlha yield). Ganesh-1 gave the highest
grain yield (4.87 tlha) with lowest disease severity of 37.40%. Similarly, Manakamana-3,
Posilo makai-1 and Manakamana-4 yielded 4.44, 4.53 and 4.43 tlha grain yield with disease
severity of 38.87, 41.60 and 41.27%, respectively. Thus, incidence and severity of the
disease can be minimized and yield can be increased by using improved maize varieties like
Ganesh-1 and Manakamana-3 in the grey leaf spot prone areas of the eastern hills.Link for e-copy: http://elibrary.narc.gov.np/?r=963 Varietal evaluation of maize against grey leaf spot disease in the Eastern Mid-hills of Nepal [printed text] / NK Dangal, Editor ; P Joshi, Author ; D.L.
