The test of the effectiviveness of Trichoderma sp. and Gliocladium sp. antagonism fungi is aimed tocontrol lanas disease (Phytophthora nicotianae) in Deli tobacco plants (Nicotiana tabaccum L.). Theaim of the research was to know the effectiveness of Trichoderma sp. andGliocladium sp.antagonism fungi in controlling lanas disease in Deli tobacco plants. The research wasconducted at Tembakau Deli Research Center of PTPN II Sampali, Medan, from May untilSeptember, 2012. The research used non-factorial RAK (cluster random design) with ten treantmentsand three repetitions: control, P.nicotianae, 5 grams of Trichoderma sp., 10 grams of Trichoderma sp.,15 grams of Trichoderma sp., 20 grams of Trichoderma sp., 5 grams of Gliocladium sp.,10 grams of Gliocladium sp., 15 grams of Gliocladium sp., and 20 grams of Gliocladium sp. The resultof the research showed that the percentage of the highest attack was found in the treatment ofP.nicotianae (25.00%), but there was no symptom (0,00%) in the treatments of control,15 grams of Trichoderma sp., 20 grams of Trichoderma sp., 10 grams of Gliocladium sp.,15 grams of Gliocladium sp., and 20 grams of Gliocladium sp. The highest plant was found in thetreatment of 20 grams of Gliocladium sp. (50,92 centimeters) and the lowest plant was found in thetreatment of P.nicotianae (31,14 centimeters). The largest number of leaves was found in treatment of20 grams of Gliocladium sp. (20,18 leaves), and the smallest number of leaves was found in thetreatment of P.nicotianae (9,25 leaves). The result of the test of Trichoderma sp. and Gliocladium sp.antagonism fungi on P.nicotianae indicated that the growth of both fungi had rapidly developed so thatP.nicotianae tended to get away from antagonism at the media in the laboratory.Keywords: Trichoderma sp., Gliocladium sp., P.nicotianae, Antagonism

ABSTRACTResearch on title testing the effectiveness of Trichoderma harzianum yeast granular formulations tocontrol white root fungus disease (Rigidoporus microporus (Swartz:fr.) van Ov) in the rubber plantnurseries. Required more efficient technologies in utilizing Trichoderma spp, one of which is makeformulations in granular form. Granular formulations easier in application, longer storage period andsupport the deployment of Trichoderma in the soil. This study aims to know the effectiveness ofT. harzianum granular formulations with a variety of mixed media in controlling white root diseasefungus in rubber plant. The research was conducted at Rubber Research Institute of Plant Sungei Putih,Deli Serdang, North Sumatra from Desember 2012-April 2013. The method used randomized blockdesign (RBD) Non Factorial consists of 10 treatments with three replications. The results showed thatthe highest disease intensity at treatment control (83.33%) and the lowest at treatment rice flour +T.harizianum (05.55%). High rubber stump buds highest at treatment rice flour + sugar + bread yeast +T. harzianum (24.44 cm) and the lowest at treatment control (7.78 cm). While soil pH was highest attreatment rice flour + tape yeast + T. harzianum ground limestone (6.33), and the lowest soil pH ontreatment rice flour + tape yeast + sulfur + T. harzianum (4.33). Growth and the antagonist ofT. harzianum higher compared with the addition of other fungi that could be a competitor for space andnutrients of T. harzianum.Keywords : Trichoderma harzianum, yeast, granular, rubber, Rigidoporus microporus
