Assessment of maize stem borer, chilo partelius swinhoe infestation in year round weekly seeded maize varieties at NMRP, Rampur and its command areas / Thakur, P.

Title : Assessment of maize stem borer, chilo partelius swinhoe infestation in year round weekly seeded maize varieties at NMRP, Rampur and its command areas Material Type: printed text Authors: Thakur, P., Editor ; G.S Bhandari ; BB Achami, Author Pagination: 288-294 p. Keywords: Maize genotypes ; maize stem borer infestation varieties temperature Abstract: Maize genotypes i.e. Arun 2 (Short duration), Rampur composite (Long duration) and
Gaurav (Hybrid) were seeded in weekly interval throughout the years at NMRP, Rampur
during two consecutive years, 201 0/ 11 and 2011112 to assess the effect of environment on
growth and development of Maize Stem Borer, Chilo partel/us Swinhoe infestation along
with other associated pests. Percent insects' damage was in the similar trend in both the
years proportional to prevailing temperature. Range of borer damage varied from 4.53% to
61.03 % in 20 I 0/1 1 and 4.4% to 64.9 % in 2011/12. The percent infestation of the years
was found highest in the month of April (58.2 %) followed by May (48.2 %), July (44.9 %)
and March (42.7 %) and approximately similar movement of damage were recorded in
other parameters (Score, Tunnel length and exit holes) too. Out of three varieties tested,
Gaurav was comparatively more sensitive to maize stem borer damage (37.7%) than Arun 2
(34.5%) and Rampur composite (32.1 %). Beside this, twenty two other miner insects and
six beneficial insects were also recorded but their damage was nominal. Furthermore,
insects survey carried out at NMRP command areas inferred that maize stem borer was
major one and more or less uniform in each location however average percent damage as
recorded in field was found more at Sukranagar, Chitwan (20.6%) than Manahari,
Makawanpur (14.6%) and Madi, Chitwan (11.3%).Link for e-copy: http://elibrary.narc.gov.np/?r=956 Assessment of maize stem borer, chilo partelius swinhoe infestation in year round weekly seeded maize varieties at NMRP, Rampur and its command areas [printed text] / Thakur, P., Editor ; G.S Bhandari ; BB Achami, Author . - [s.d.] . - 288-294 p.

Nepali, Author ; Oevendra Gauchan, Author ; Naresh S. Thakur, Author ; Sharma, Bimala, Author ; S.M. Amataya, Author ; B. Bhat, Author Pagination: 189-196 p. Languages : English (eng) Keywords: Biophysical problems, coffee cultivation, economy, export, marginal land,
socioeconomic, white stem borerAbstract: Coffee (Cofffea spp) is an important and emerging cash gener_ating crop after tea in the
mountains of Nepal. The study was carried out in 2007 by a multi disciplinary team of
economics and horticulture in order to explore economics of coffee production system.
The study uses combination of review, participatory rural appraisals (PRA) and sample
household suNey to collect information on coffee production and marketing from
selected pockets of Syangja and Gulmi districts. The primary data were collected from
suNey of purposively selected 65 coffee producing farm households from two villages:
Sirubare-Syangja and Digam-Gu/mi. The findings showed that currently coffee is grown
in small-scale organic production system with limited use of modem technologies and
improved practices. Varieties used in production are traditional and low yielding.
Average coffee farm size is 1.36 ropani. Mean yield of fresh cherry is 169 kg per
ropani. Coffee is an important contributor of household income. Economic analysis
revealed . that coffee production is profitable in both the villages. The important
constraints identified are white stem borer followed by Jack of improved seedlings,
adverse and poor soils inadequate shedding, low market price, delay in payment, lack
of credit facility and labor shortage.Link for e-copy: http://elibrary.narc.gov.np/?r=244 Economics of Coffee Production: A Case study of Slrubare of Syangja and Digam, Thanapati of Gulmi District [printed text] / S Gautam, Author ; Megh B.

Title : Evaluation of different pesticides for the management of rice stem borers Material Type: printed text Authors: G.S Bhandari, Editor ; B. Chaudhary ; B Sapkota, Author ; D.N Mahato, Author ; S.K Upadhyaya, Author Pagination: 304-309 p. Keywords: Botanical pesticide ; dead heart pesticides stem borer white ear Abstract: Rice Stem Borers have been recognized as the national pest of Rice in Nepal. Past studies
have estimated about 40% of total loss in Rice is due to Rice Stem Borer. An experiment
was conducted at Regional Agricultural Research Station, Tarahara during rice growing
season of 2011 and 2012 with the objective of evaluating differential efficacy of different
pesticides combinations against Rice Stem Borers. The experiment had 12 different
pesticides combinations laid out in a Complete Block Design with three replications.
Responses were recorded on count of dead hearts, count of white heads and grain yield to
compare the treatments. The effect of treatments on count of dead hearts was found highly
significant. Number of dead hearts was the least on Seedling Root Dipping with
chJorpyrifos 20% EC @ 2 milL of Water+ three sprays of imidacloprid 17.8% SL@ 1
ml/2L of water 30, 40 and SO days after transplanting (DAT) followed by Seedling Root
Dipping with chlorpyrifos 20% EC@ 2 milL of Water+ three sprays of Lantana camera
Extract @ S% solution 30, 40 and SO DA T and Root Dipping with chlorpyrifos 20% EC @
2 milL of water + Urea 20 gm IL of water for 3 hours + Lantana camera @ S% solution at
30, 40 and 50 OAT. The effect of treatments for count of white ears was also highly
significant. The Seedling Root Dipping with chlorpyrifos 20% EC @ 2 mi/L of Water+
three sprays ofimidacloprid 17.8% SL@ 1 mi/2L ofwater 30,40 and 50 DAT recorded the
lowest count of white ears followed by Root Dipping with chlorpyrifos 20% EC @ 2 milL
of Water + three sprays of Sweet Flag Stolen Extract @ 5% solution 30, 40 and 50 DA T
and Root Dipping with chlorpyrifos 20% EC @ 2 milL of Water + Lantana camera extract
@ 5% solution Spray 30, 40 and 50 DAT. The variation on grain yield was significant due
to the treatments. The highest grain yield was obtained from Root Dipping with
chlorpyrifos 20% EC @ 2 mVL of Water and Urea 20 g /L for 3 hours + three sprays of
imidacloprid 17.8% SL @ 1 ml/2L of water at 30,40 and 50 DAT followed by Root
Dipping with chloropyrifos and Urea 20 g /L for 3 hours + three sprays of Sweet Flag @
5% solution and Root Dipping with chlorpyrifos 20% EC @ 2 ml/L of Water+ three
sprays of Lantana camera Extract. All the treatments combinations were significantly
superior to the control and the standard check (carbofuran 3G) for all parameters
considered. This study concluded that application of botanical pesticides in combination
with chemical pesticides is effective for managing rice stem borer.Link for e-copy: http://elibrary.narc.gov.np/?r=958 Evaluation of different pesticides for the management of rice stem borers [printed text] / G.S Bhandari, Editor ; B.
