RESPON PHAEOPHLEOSPORA SP. TERHADAP FUNGISIDA BERBAHAN AKTIF METIRAM SECARA IN VITRO
ABSTRACT: Phaeophleospora sp is
one of diseases which attack eucalyptus plant particulaily on eucalyptus
nursery. This disease has been spread almost in the whole world. North Sumatera
Control of the disease itself still use a fungicide and one of them is the
fungicide active ingredient Metiram 70%. The purpose of this reseaech is to
know the response of Phaeophleospora with fungicide Metiram substance 70%
treatment with 0,4 ,0,8 ,1,2 and 1,6 mg/ml as concentrate. Response which
measured was colony growth (wide, diameter, spora density, and change that
happened to hifa). Research conducted at Forest Biothechnology Laboratory and
Pest Plant Pathology Laboratory, Agriculture Faculty, University of North
Sumatera. Used general linear non factorial with five times repetitions. The 70% metiram treatment in 0,4, 0,8,
1,2 and 1,6 mg/ml significant to the
growth (wide, diameter, barriers relative and spore density) and also caused
swelling on hyphae and change of form, tekstur and the color of colony
Phaeophleospora sp. in vitro.
