| dc.description | In Bangladesh, potato (Solanum tuberosum) is the third important food crop.
Through out the year, it plays an important role in supplying vegetables in the
country and can solve the nutritional problems to a great extent for the lower
income group. According to Bangladesh Bureau of Statistics (Anonymous,
2005) during 2004-2005, the production of potato was about 60 lac metric tons
from 4 lac hectare of land. The national tuber yield is about 15.0 t/ha, which is
lower as compared to other potato growing countries of the world. The major
constraints in potato production are: the incidence of wide range of pests and
diseases, inadequate availability of quality seed, non adoption of modern
technology of crop production etc. At present the country can supply only 5.0 %
of quality seed against country demand (Dey et al., 2008). Among the various
factors responsible for such low yield, diseases play an important role. | en_US |
| dc.description.abstract | A study was made on the field incidence and management of late blight of
potato due to Phytophthora infestans during 2006-2007 cropping season.
Survey of potato field at Dinajpur district revealed that late blight was very
much frequent in all over the surveyed upazillas during 2006-2007 cropping
season. Of them, Parbatipur (56%) was the worst affected by late blight
followed by Birampur (49.7%), Khansama (48.6%), Birgang (43.3%), Birol
(39.6%), Hakimpur (39%) and Fulbari (37.6%). During 2007-2008 cropping
season some upazillas of Dinajpur district were found apparently free from late
blight incidence viz. Dinajpur sadar, Birgang, and Kaharol. Some of upazillas
less affected viz. Khansama, Parbatipur, Chirirbandar, Fulbari and Bochagang.
Of them, Nawabgang (26%) was the worst affected by late blight followed by
Birol (25.8%) and Birampur (23.3%). Ridomil was widely used fungicide in
controlling late blight throughout the surveyed area. Altogether the
effectiveness of five fungicides was tested against late blight. All the fungicides
significantly reduced the late blight incidence over control. The lowest plant
infection was recorded for fungicides namely, Ridomil gold and Acrobat. The
role of number of fungicidal spray in minimizing the incidence of late blight of
potato indicates that the number of fungicidal sprays had significant influence
on late blight incidence. The incidence of late blight infection was highest in
single spray of fungicides and it decreased gradually with increasing number of
fungicidal sprays. | en_US |
