RESPON CYLINDROCLADIUM SP. TERHADAP FUNGISIDA BERBAHAN AKTIF METIRAM SECARA IN VITRO
ABSTRACT: Cylindrocladium sp.
is a pathogen cause disease that attack eucalyptus and it was
the highest type of disease that attack eucalyptus in toba pulp lestari.
Fungicide was used to eradicate and prevent the growth of pathogens. One of the
fungicide which used was systemic
fungicide with active substance metiram 70 %. The purpose of this study was to
measure the area, diameter, density of the spore ,and to characterize the
hyphae form of Cylindrocladium sp after being treated metiram 70 % in vitro in
different concentrations. Sample that used taken from cylindrocladium
collection from previous research. The result of this study showed that the
most efective concentration of fungicide treatment in inhibiting growth and
development area of cylindocladium sp was treatment 2,0 mg/ml. In observation
of spore density and hyphae structures of cylindrocladium sp, the fungicide
that given was able to give tangible effect but in observation of relative
inhibiton, concentration of fungicide gave intangible effect in providing
inhibition to pathogen of cylindrocladium sp.
