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.
