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 : Screen House System to Produce Quality Planting Materials of Citrus in Banepa Material Type: printed text Authors: C. Regmi, Author ; I.P. Kafle, Author ; Paudyal, K.P., Author ; R.P. Devkota, Author ; G. Aryal, Author ; G. Awasthi, Author Pagination: 89-92 p. Languages : English (eng) Keywords: Citrus saplings,' graft transmissible diseaes, nursery, screen. house, vectors Abstract: Citrus is the dominant fruit crop in mid-hills of Nepal. The productivity is very low
(about 10 mt/ha) as compared to 20-25 mtlha world average. It is mainly due to the
traditional methods of cultivation, use of seedlings as planting materials, wide
spread of graft transmi~sible diseases such as Huanglongbing and other viral
diseases and infestation of most devastating fungal. diseases like Phytophthora.
Production of grafted saplings of good quality and supply to the farmers are the
prerequisites to increase the productivity of citrus. The project was started in 2005
with the construction of well managed two screen houses (20x9x3 .m3 in size) in
Banepa for production and distribution of disease free planting materials in Nepal.
The project applied the achievements made by the other institutions. Mandarins
access no. J-90 selected based on the 5 y~ars evaluation by National Citrus
Research program and confirmed HLB free in PCR test by NAST, has been used
for mother plant. The screen with 10 mess was usee! in the screen .house which did
not allow entrance of any insects including aphids and -psyllids .a,n.d avoid- the
chances of infection of nursery plants by any type of vector transmissible disea~es.
Seventy mother plants are being maintained in thE! screen house. The screen
houses had the capacity of producing 10 thousand grafted citrus saplings annually.
Good quality citrus saplings were produced within a year due to enhanced growth
of plants inside screen house. This is one of the .best moctels for producing quality.
