DISEASES OF JAMUN (Syzygium cuminii) SEEDLING IN THE NURSERIES OF BANGLADESH AND THEIR ECO-FRIENDL Y MANAGEMENT

Abstract

The existing health situation of seedlings of jamun (Syrygium cuminii) and management strategies of nursery diseases of seedlings of jamun species in the country is in a stage to be upgraded for successful fruit and timber production to meet the national demand. Plant propagation and nursery management - a vital link in the production of quality planting material (QPM). Experiments were carried out during 2005- 08 to study the status of diseases on seedlings of jamun and development of an environment friendly disease management practice. Important plant pathogens viz. Gloeosporium psidi, Pestalotia psidi and Cephaleuros virescens were detected and identified. Comparative effectiveness of BAU-biofungicide either alone or in combination with two fungicides - Cupravit and Bavistin were evaluated on jamun in the nursery. Among the treatments applied, Trichoderma harzianum based BAU-Biofungicide showed excellent result in controlling leaf spot disease on jamun. BAU-Biofungicide, as an alternate to chemicals can successfully be used.
