FORMULATION OF
AVICENNIA MARINA PELLETS AND ITS APPLICATION IN CONTROLLING ROOT
DISEASES IN LEGUMINOUS AND NON LEGUMINOUS PLANTS
MARIUM TARIQ AND
SHAHNAZ DAWAR
Abstract: After
slight modification, pellets of Avicennia marina (Forsk.) Vierh
plant parts viz., leaves, stem and pneumatophore were prepared from
pyrophyllite at two different ratios 50:50 and 25:75 and incorporated in
soil @ 3, 5, 7 and 10 pellets/pot. A pot experiment was designed to
assess its effectiveness in promoting plant growth and suppression of
root rot diseases. Observation showed that 5 leaves and stem powder
pellets with 50:50 ratio gave significant results in increasing plant
weight, height and controlling root rot diseases caused by pathogenic
fungi viz., Rhizoctonia solani Kühn, Macrophomina phaseolina
(Tassi) Goid and Fusarium oxysporum Schlecht on cowpea (Vigna
unguiculata [L.] Walp) and brinjal (Solanum melongena L.)
plants. Of the different dosages used, 5 pellets/pot were found to be
best followed by 3 and 7 in controlling root rot diseases and promotion
of growth parameters.
