DESCRIPTION
The national consumption of fruits is low in Bangladesh. The country produces less than 30% of fruits needed to meet the minimum daily requirement for its population. As a consequence, widespread national deficiencies in vitamin A and C, iron and other nutrients that causes debilitating illness among the population. Fruits worth millions of taka are imported at the cost of valuable foreign currency to meet the deficit demand of fruit consumption for reduction of vitamin and mineral deficiencies in the country. Around 10,000 nurseries are engaged in seedling production all over the country. Though fruit seedlings worth millions of Taka are traded every year in the country, but the status of seedlings in the nurseries is not well attended for certification of health and quality. As a result poor quality seedlings are traded among the farmers. This is one of the major causes for low production of fruits in the country. The majority of poor farmers can not afford to buy fruits. Thus homestead gardening appears to be an appropriate means to increase the availability and consumption of fruits in rural households. The country abounds with a large variety of tropical and sub-tropical fruits, where seedlings are frequently affected by different diseases. These points encourages of taking program for improving status and health of planting materials of fruit species in Bangladesh. This booklet is an output of the research project entitled “Surveillance of seedling diseases of some important fruit species in Bangladesh with molecular characterization of pathogens and eco-friendly model development for their management” financed by PIU-BARC (NATP phase-1), Bangladesh Agricultural Research Council, BARC, Farmgate, Dhaka-1215. Most of the nurseryman and women are not aware of diseases of their seedlings. As a result they also suffer financially for production of quality seedlings. This booklet will obviously be helpful for taking care of their seedlings to avoid the diseases. This can be used as a guide book. Further, this booklet will be useful to teachers, students and researchers in this discipline. TheTRANSCRIPT

Preface
The national consumption of fruits is low in Bangladesh. The country produces less than 30% of
fruits needed to meet the minimum daily requirement for its population. As a consequence,
widespread national deficiencies in vitamin A and C, iron and other nutrients that causes
debilitating illness among the population. Fruits worth millions of taka are imported at the cost
of valuable foreign currency to meet the deficit demand of fruit consumption for reduction of
vitamin and mineral deficiencies in the country. Around 10,000 nurseries are engaged in
seedling production all over the country. Though fruit seedlings worth millions of Taka are
traded every year in the country, but the status of seedlings in the nurseries is not well attended
for certification of health and quality. As a result poor quality seedlings are traded among the
farmers. This is one of the major causes for low production of fruits in the country. The majority
of poor farmers can not afford to buy fruits. Thus homestead gardening appears to be an
appropriate means to increase the availability and consumption of fruits in rural households. The
country abounds with a large variety of tropical and sub-tropical fruits, where seedlings are
frequently affected by different diseases. These points encourages of taking program for
improving status and health of planting materials of fruit species in Bangladesh. This booklet is
an output of the research project entitled “Surveillance of seedling diseases of some important
fruit species in Bangladesh with molecular characterization of pathogens and eco-friendly model
development for their management” financed by PIU-BARC (NATP phase-1), Bangladesh
Agricultural Research Council, BARC, Farmgate, Dhaka-1215. Most of the nurseryman and
women are not aware of diseases of their seedlings. As a result they also suffer financially for
production of quality seedlings. This booklet will obviously be helpful for taking care of their
seedlings to avoid the diseases. This can be used as a guide book. Further, this booklet will be
useful to teachers, students and researchers in this discipline.
