Abstract:
Rubber represent one of the agricultural important commodity good to
international and also for Indonesia. Rubber agriculture growth in Riau specially
in Kampar Regency there are problems in improving quality and quantity of
rubber product for example attack of pest and disease. One of the most dangerous
disease is root disease that is white root disease. White root disease emerge
because of the new opening land for rubber plantation that not clean enough so
that leave the roots picking that are decaying so that become the growing medium
for white root. Strive operation of white root can be conducted by eliminated the
infection source and usage of chemicals substrate but it's need very big expense.
Usage of pesticide can generate environmental contamination, death of natural
enemy, incidence of crop resistence and residu. Natural operation in overcoming
damage of crop because of organisme effect in agriculture have developed and
one of them is usage of Trichoderma sp. Trichoderma sp. have been known as a
natural agent most effective to control crop disease which is because of soil
mushroom. The objective of this research is to test the antagonisme ability of
some dose of local Trichoderma sp. in controling Rigidoporus microporus cause
of white root disease at rubber crop. This research conducted from November
2006 up to June 2007 at Disease Laboratory of Faculty Of Agriculture Riau
University. The parameter is to perceived speed of Rigidoporus microporus
colony growth, speed of Trichoderma sp. colony growth, the Trichoderma sp.
pursue ability to Rigidoporus microporus growth at medium of PDA (%). The
result of this research can be summarized that Trichoderma sp. have the ability to
pursue the growth of Rigidoporus microporus.
