PENGGUNAAN DEBARYOMYCES SP. DAN SCHIZOSACCHAROMYCES SP. DENGAN ADJUVANT UNTUK PENGENDALIAN PENYAKIT ANTRAKNOSA PADA MANGGA

Abstract

The aimed of this research to find out the effectifity some adjuvant to enhance Debaryomyces
sp. and Schizosaccharomyces sp. actifity as agens biocontrols against anthracnose pathogen C.
gloeosporioides on mango.
The laboratory experiment included testing adjuvant conferral for enhance anthracnose disease
obstruction on mango. The experiment with Complete Randomized Design and 3 replication. There
were 13 treatment,it’s A1 = control (only pathogen); A2 = yeast Debaryomyces sp. ; A3 = yeast
Schizosaccharomyces sp.; A4 = yeast Debaryomyces sp.+ Schizosaccharomyces sp.(mixture); A5 =
Debaryomyces sp. + Tween 1 %; A6 = Schizosaccharomyces sp. + Tween 1 %; A7 = mixture yeast
+ Tween 1 %; A8 = Debaryomyces sp. + CaCl2 2%; A9 = Schizosaccharomyces sp. + CaCl2 2%;
A10 = mixture yeast + CaCl2 2%; A11 = Debaryomyces sp. + Trehalose 2%; A12 =
Schizosaccharomyces sp. + Trehalose 2%; A13 = mixture yeast + Trehalose 2%.
Results of the experiment indicated Debaryomyces sp. and Schizosaccharomyces sp. yeast in
single or mixtures with or without adjuvant to be able to grow on mango fruit surface, and effective
inhibited development of the anthracnose disease caused of C. gloeosporioide on mango fruit that
shown with significantly reduced lesion size and incubation periods 4 days longer.
