Title : Citrus Diseases Prevalent in Baitadi District Material Type: printed text Authors: C. Regmi, Author ; G. Awasthi, Author ; Bikram Thapa, Author ; Paudel, C.L., Author Pagination: 44-49 p. Languages : English (eng) Keywords: ELISA test, Huanglonbing, powdery mildew, PCR technique, tristeza virus Abstract: Field survey on the prevalence of diseases was conducted during March and June 2001 in 17
commercial citrus orchards from Gajari. Bhumeswar Silang and Basuling VDCs. Laboratory
tests were made for the confirmation of Citrus Tristeza Virus (CTV) and Huanglonbing on the
samples collected from suspected trees in Royal Nepal Academy of Science and Technology's
Biotechnology Lab. The Enzyme Linked Immunosorbent Assay test was used for testing
Citrus Tristeza Virus (CTV) while Polymerase Change Reaction technique was used for
Huanglonbing. Powdery mildew was found one of the major problems especially in the
mandarin trees while anthracnose, sooty mold and greasy spot were recorded as minor
problems among the fungal diseases. The laboratory tests reveals that the frequency of CTV
(non-stem pitting strain on mandarin) is very low about 7.7 percent and that of
Huanglongbing (HLB) is about 10 percent. No vector of HLB was observed during the survey
but the several colonies of aphids - vectors of CTV were present in different orchards.Link for e-copy: http://elibrary.narc.gov.np/?r=452 Citrus Diseases Prevalent in Baitadi District [printed text] / C.

Title : Effect of Sowing Time on Incidence and Severity of Major Diseases of Rapeseed-Mustard Material Type: printed text Authors: Sharma, B.P., Author Publication Date: 1997 Article on page: 43-48 p. Languages : English (eng) Keywords: Alternaria blight, downey mildew, Mustard diseases, powdery white rust. Abstract: A field experiment was conducted during 1992-1994 to evaluate the effect of different dates of sowing on incidence and severity of the major diseases of rapeseed-mustard (Brassica compastris, var. toria) under rainfed condition of Nawalpur, Sarlahi. A toria variety 'Vikas' was sown in 10 different dates starting from Sept. 5 to Dec. 5 at 10 day intervals. The mustard sown on 25 Sept. and 5 Oct. showed low severity (13-22%) of Alternaria blight (Alternaria brassicae), complete escape of downy mildew (Peronospora parasitica) and powdery mildew, (Erysiphe cruciferarum) and partial escape of white rust (Albugo candida). Seed yields 703 and 804 kg/ha obtained form those two dates were found significantly higher than those obtained from other seeding dates. Incidences and severities of diseases increased gradually in successive sowing dates.

Title : Evaluation of cucumber genotypes for open field and plastic house in the western hills of Nepal Material Type: printed text Authors: Gautam, I.P., Author ; K. P. Upadhya, Author ; J.N Chaudhary, Author ; A.H Khan, Author ; C.K. Timilsina, Author Pagination: 190-198 p. Languages : English (eng) Keywords: Cucumber genotypes, plastic house, powdery mildew, downy mildew Abstract: Field experiments were conducted to find out the response of different cucumber genotypes for cultivation under plastic house and open field in outreach site of Regional Agricultural Research Station (RARS), Lumle at Hemja, Kaski during February and April planting seasons of 2004/05. Ten exotic and indigenous cucumber genotypes were tested in two planting dates; first on February and second on April in open field and under plastic house. The genotypes Mahyco Green Long (2807 kg/ropani) and Bhaktpur Local (2748. 5 kg/ropani) were recommended for both plastic house and open field conditions due to their higher yield for February planting…………………
