Title : Controlling Foliar Blight of Wheat through Nutrient Management and Varietal Selection Material Type: printed text Authors: Yuva R. Kandel, Author ; Jay P. Mahato, Author Publication Date: 2009 Article on page: 77-83 p. Languages : English (eng) Keywords: AUDPC, Bipolaris sorokiniana, disease resistance, grainyield, Helminthosporium leaf blight, Pyrenophora tritici-repentis Abstract: Helminthosporium leaf blight, a complex of spot blotch caused by Bipolaris
sorokiniana and tan spot caused by Pyrenophora tritici-repentis, is one of
the most important foliar diseases of wheat in Nepal. It appears in almost all
wheat growing areas and causes severe yield loss every year. A study was
conducted at Regional Agriculture Research Station (RARS), Tarahara,
Sunsari during 2004-05 and 2005-06 wheat growing seasons to elucidate role
of nitrogen in wheat genotypes for management of the disease. Field
experiment was laid out on split plot design with three replications. Four
doses of nitrogen in six different promising genotypes were tested. Nitrogen
levels higher than 50 kg ha-1 significantly reduced disease severity and
increased grain yield in all genotypes but there was no significant differences
in grain yield in the first year. In the second year, grain yield difference
among the genotypes was significant. Area under disease progress curve
(AUDPC) was not significant between two doses 100 and 150 kg ha-1. The
wheat genotypes showed different reactions to disease. Genotype BL 2047
had the lowest incidence of disease followed by BL 1887, whereas BL 2217
had the highest incidence of the disease. Genotype BL 2196 produced the
highest grain yield (2172 kg ha-1) and the lowest grain yield was obtained in
Bhrikuti followed by BL 2089. These results suggested that fertilizer should
be applied in soil at balanced dose 100:50:50 N:P2O5:K2O kg ha-1. Growing
relatively resistant genotypes with the balance dose of fertilizers can reduce
foliar blight severity in wheat.Link for e-copy: http://elibrary.narc.gov.np/?r=11

Title : Determination of a relationship between disease severity of leaf blight of wheat and grain yield loss Material Type: printed text Authors: P.C.P. Chaurasia, Author Pagination: 355-359 p. Languages : English (eng) Keywords: Leaf Blight, Commulative disease severity regression. Abstract: Sixty-six single hill plants were randomly selected and pagged Disease severity of leaf blight was scored on all leaves including flag leaf separately. Three srades of commulative disease severity were calculated and regressed with grain yield to establish a relationship between percentage disease severity and grain yield The commulative disease severity based on flag leaf or 2nd plus flag leaves gives better estimate of yield loss at various leaves of disease severity.

Mandal, Author Pagination: 203-207 p. Languages : English (eng) Keywords: Banmara, Blister blight, Botanicals, Neem, Sisnu,Titepati Abstract: Blister blight caused by Exobasidium vexans Massee is a major disease of tea in Nepal
which inflicted severe crop losses. An experiment was conducted in RCBD with four
replications during 2061/62, 2062/63 and 2063/54 to test effectiveness of locally
available botanicals in crude form for the management of blister blight under natural
epiphytotic condition at Guranse Tea Estates, Dhankuta and Chiya Bistar Yojana, &
11/am. The treatments were Multi-Neem (4 mVIit of water), Titepati 20% solution (2 kg
fresh green leaf in 21iter of water), Sisnu 20% solution (2 kg fresh green leaf in 21iter of
water), Banmara 20% solution (2 kg green leaf in 21it water) and 5% mixture of Neem,
Titepati, Sisnu, and Banmara solution in 2 liter of water and water spray as control.
Mixture of Neem, Titepati, Sisnu, and Banmara was found effective for the
management of blister blight of tea. Hence, this mixture treatment was found superior
than other individual treatments and also increased green leaves tea yield. Most of the
tea planters have been using chemical pesticide.s at higher dose to manage this
disease. This practice leads misuse and overuse of chemical pesticides on tea which
creates various problems on human health, water and environmental pollution. Tea as
a value added exportable commodity and possibility of toxic residues in the processed
tea is a major concern to the consumers. Therefore, this investigation could be helpful
to reduce misuse and overuse of chemical pesticides, safe for human health and
reduce water and environmental degradation.Link for e-copy: http://elibrary.narc.gov.np/?r=246 Evaluation of Botanicals ·for the Management of Blister Blight (Exobasidium Vexans) in Tea [printed text] / P.K. Yadav, Author ; Mahto, B.N., Author ; D.L. Mandal, Author . - [s.d.] . - 203-207 p.

Title : Evaluation of Pepper Genotypes Against Phytophthora Blight Disease Material Type: printed text Authors: R.D. Timila, Ph.D., Author Pagination: 41-46 p. Languages : English (eng) Keywords: Incidence, genotypes, blight, crown/root rot Abstract: Pepper (Capsicum annuum L and C. fruitescens L.) is an important high value crop grown for
vegetable and for spice purposes. Phytophthora blight caused by Phytophthora capsid Leoni an is a
serious disease of pepper causing foliar blight, fruit rot and crown/root rot phases. Crown/root rot
phase is the most devastating phase of the disease. Experiments were conducted with the objective to
find resistant/tolerant varieties against phytophthora blight disease. Seedling evaluations were carried
out in inoculated conditions under screenhouse during 2007-2009. inoculum of zoospore suspension of
1oM spore/ml was used at the rate of 25 ml per plant at 5 week old stage of seedling. Based on the
terminal disease incidence (5-7 weeks after inoculation), NS 1701, Chandani, Tara, Angarika and
Premium were found resistant in seedling assay. During 2010 and 20/1, on-farm evaluation .of
selected genotypes (1 1-1 3) was carried out in the farmers' field with the history of Phytophthora blight
in chilli pepper. The experiment was conducted in hVo replications each with 16 plants. NS 1701, Tara,
Angarika and Chandani were found resistant. Other genotypes NS 214, NS 1101, Go/i and Premium
were moderately resistant. Lesser fruit rot was found in Angarika, NS 1701, Long Wei and Pusa Jwala
compared to other varieties. Those resistant to moderalely resistant genotypes could be used as one of
the tools of integrated disease management ofphytop/lthora blight in disease prone areas to minimize
crop/yield losses.Link for e-copy: http://elibrary.narc.gov.np/?r=1561 Evaluation of Pepper Genotypes Against Phytophthora Blight Disease [printed text] / R.D. Timila, Ph.D., Author . - [s.d.] . - 41-46 p.
