Efficacy of sedomil 72WP and recozeb 80WP to control die-back (Colletotrichum gloeosporioides) of tea in Bangladesh
...metalaxyl) to control of dieback disease (Colletotrichum gloeosporioides) of tea in Bangladesh. The pathogen, C. gloeosporioides was isolated from the dieback infected tea twigs on PDA medium. Mycelial blocks of the isolated pathogen were transferred to PDA plates amended with sedomil 72WP (mancozeb) @ 720, 1080, 1440 and 1800 ppm and recozeb 80WP (mancozeb + metalaxyl) @ 800, 1200, 1600 and 2000 ppm concentrations. Sedomil ...

...ed because of decline or dieback disease but unluckily there is no suitable solution against this disease. There is a need to develop the resistant varieties and to improve the quality of seed. Disease may be reduced by selecting the improved genetic material. Because it will have a good impact on product quality, economic output and its potential against insect pest or disease. ...

...ere badly damaged by the dieback. The soil samples were analyzed for their physico-chemical and nutritional properties. The objective was to find out, if any of the unfavourable soil properties or nutritional deficiencies had been the cause of the dieback. About 3 % of the samples were found to be too sandy to retain and supply water to trees over a longer period of time and 60 % samples were too clayey to permit free moveme...

dieback in Leucaena leucocephala, Albizzia lebbek,
Acaica nilotica and A. ampliceps. The results indicated
that the highest salt concentrations (.0.878% - 1.580%)
produced deleterious changes in soil pH and resulted in
dieback injury in A. nilotica, A. lebbek and L.
leucocephala in an increasing order. Although the growth
of A. ampliceps was reduced appreciabl...

The presence of Fusarium circinatum was confirmed through morphological identification. Pathogenicity tests conducted on two years old seedlings of Pinus wallichiana and Pinus roxburghii showed that Pinus wallichiana is more susceptible to the fungus by exhibiting larger lesions compared t...

...ing root and fruit rots, dieback, stem cankers, leaf spots, leaf and pod blights, and seed decay (Udayanga et al., 2011). Diaporthe helianthi is the causal agent of one of the most important diseases of sunflower (Helianthus annuus) worldwide, and is also listed in the Chinese quarantine directory (Thompson et al., 2011). For plant pathologists, studying of phytopathogenic Diaporthe spp. is therefore particularly important to work on wide range of plant disea...
