Status of Tomato Yellow Leaf Curl Virus in Tomato in the Western Hills of Nepal / Ghimire, S.R. in Nepal Agriculture Research Journal, Vol. 4 (2000/2001)
[article]
Title : Status of Tomato Yellow Leaf Curl Virus in Tomato in the Western Hills of Nepal Material Type: printed text Authors: Ghimire, S.R., Author ; Subedi, Phul Prasad, Author ; Green, S.K., Author Publication Date: 2000 Article on page: 1-4 p Languages : English (eng) Keywords: Bemisia tabaci, Lycopersicon esculentum, tomato, yellow leaf curl virus, whitefly Abstract: Tomato cultivation in rainy season is being endangered and is becoming less profitable because of
tomato yellow leaf curl virus (TYLCV) infection. Studies were conducted at Agriculture Research
Station, Lumle to assess the incidence of TYLCV and associated yield losses in various
commercial tomato growing pockets of the western hills during the period of 1995 and 1997. The
studies revealed a high incidence of the disease in most tomato growing pockets and yield losses
of 40% or even higher have been reported in some areas like Risingpatan, Tanahun and Kudule, of
western hills of Nepal. Laboratory analysis of the diseased samples by Asian Vegetable Research
and Development Center revealed the presence of three different strains of TYLCV: Banglore I,
Banglore II and Sri Lanka in the western hills. The TYLCV vector, whitefly (Bemisia tabaci
Gen.), was found active throughout the crop growing period in some commercial tomato growing
pockets. Therefore, research on the development of effective TYLCV management technology is
needed to sustain rainy season tomato cultivation in the western hills of Nepal.Link for e-copy: http://elibrary.narc.gov.np/?r=85

2067/068(2010/1 I) and 2068/069 (2011 / 12) with a view to validate farmers' indigenous
knowledge on Mungbean Yellow Mosaic Virus disease management in blackgram. During
2067/068 six treatments viz. cow's milk spray, seed priming, cow's urine spray, mohi spray,
turmeric powder suspension spray and control were tested. Tn the fiscal year 2068/069 the
treatments were modified as cow's milk spray, seed priming with sodium molybdate , cow's
urine spray, spray of extract of mixture of botanicals and control. Weed host of the virusAgeratum
spp and whitefly (Bemisia tabaci Glenn) vector populations were found abundant
in both the years. Blackgram genotype used in the first year was BLG 0003-2-l (moderately
tolerant to MYMV) and Chanpbas Local (highly susceptible to MYMV) in the second year.
None of the treatments were statistically significant to manage MYMV in both the years.
However, cow's milk spray reduced disease severity, increased hundred seed weight and
improved grain yield during 2067/068 and spray of leaf extract of mixture of botanicals
reduced disease severity and increased grain yield to some extent in the second year. Disease
severity was less in the first year due to the use of moderately tolerant genotype and very high
during the second year because of the use of highly susce ptible cultivar. Since the virus is
vector borne and there is abundance of alternate and collateral hosts in terai and inner terai
use of resistant/ tolerant varieties, vector control and removal of alternate and collateral hosts
are some of the possible ways to manage MYMV in blackgram, soybean and mungbeanLink for e-copy: http://elibrary.narc.gov.np/?r=918 Validation of farmers indigenous knowledge to manage mungbean yellow mosaic virus in blackgram [printed text] / Dhana Bahadur Gharti ; Subash Subedi, Author ; Tek Nath Ghimire, Author . - [s.d.] . - 319-322 p.

virusm antiviral agents.Abstract: Number of viruses infects cucurbits. In Nepal, Cucumber mosaic virus (CMV), Zucchini yellow mosaic
virus (ZYMJI), Watermelon mosaic virus (WMV) 1 and 2, Squash mosaic virus (SqMV) and Cucumber
green mottle mosaic virus (CGMMV) are infecting cucurbits. These viruses were identified
serologically by Enzyme Linked Jmmuno Sorbent Assay (ELISA). Among the viruses of cucurbits,
majority are mechanically transmissible in the sap of infected plants. Some are seed-borne such as
CMV, ZYMV. CGMMV and SqMV. Usually more than one virus infect cucurbits at the same time and
cause economic loses. The objective of the experiment was to find suitable methods to minimize viral
diseases of cucurbits. Antiviral products and locally available materials known to have antiviral
properties as Vicfovirus, Bioleafcare, Fresh cow milk, Liposome, Turmeric powder, Jeebatu, Anti-V S
(Natural Plant Virus Control Agent) and Oshin, the insecticide, also were tested to manage viral
diseases of zucchini squash on pots and infield condition. Fresh cow milk, Anti-V S, Liposome and
Victovirus helped to lower virus disease severity up to 6 weeks of diseases observation.Link for e-copy: http://elibrary.narc.gov.np/?r=1565 Viral Diseases of Cucurbits Crops and Their Management in Nepal [printed text] / S Joshi, Author ; R.D Timila, Author ; C.
