Pemanfaatan Ekstrak Kompos dan Jamur Antagonis Trichoderma sp. untuk mengendalikan Powdery mildew pada Apel (Malus sylvestris Mill.)
Abstract
Powdery mildew disease caused by Podosphaera leucotricha is one of the key diseaseon apple trees. This disease wide spread on East Java and crop loss caused this disease for about 50%
per year. The chemical control methods are not always economical or effective. Another promising
alternative is application of biological control. Trichoderma spp. are potencially as biological control
agent because its has strong antagonis characteristic. The purpose of this experiment was to determine
the optimal straw composted extract and effectivity of Trichoderma spp. isolates antagonis fungus to
control Powdery mildew on apple trees. The first phase was arranged in completely Randomized
Design in laboratory by in vitro tested to determine the best isolates of fungus for futher tested. The
second phase was field experiment was used Randomized Block Design, two factors. The first factor
were composted extract with different cattle faeces stater and the second factor were Trichoderma
spp. isolates and one control. The result of experiment indicated that laboratory and field experiment
could be control Powdery mildew. T3 is the best isolate for decrease this disease. Composted extract
showed that decrease effect to disease control in the laboratory, but didnot on the field. Straw
composted extract with cattle faeces stater and combination of straw composted extract with cattle
faeces stater could be pursued Powdery mildew (13,88% disease intensity).
