RESPON CYLINDROCLADIUM SP. TERHADAP FUNGISIDA BERBAHAN AKTIF MANCOZEB SECARA IN VITRO
ABSTRACT: Cylindrocladium sp.
is one of the pathogens trigger dangerous diseases that blight the eucalyptus
plant. Fungi is one of the pathogens that attack the breeding ground and
nursery eucalyptus in various parts of the world, including Indonesia. Efforts
to control its spread by means of direct control is by the use of fungicides.
Fungicides are used in this research is a contact fungicide mancozeb 80% active
ingredient. The study aims to measure the growth of the colonies, the relative
constraints, the density of spores and hyphae shape changes Cylindrocladium sp.
after treated with 0, 0.4, 0.8, 1.2 and 1.6 mg / ml. The sample used was taken
from the collection of fungi in Forestry Biotechnology Laboratory. The research
was conducted in February 2015 until April 2015 at the Biotechnology Laboratory
of Forestry, Department of Forestry and in the Laboratory of
Disease Study Program Plant Pests and Diseases, Faculty of Agriculture,
University of North Sumatra. Results of the study are significant response at
each concentration fungicide mancozeb. Response significant effect starting
from the 12th day until the 16th day of observation. The response of the real
effect is diameter growth, barriers relative density of spores. Besides
treatment causes swelling and breakdown of the structure of hyphae.
