Abstract

Cabbage (Brassica oleracea L.) was a vegetable crops cultivated in the highlands to meet the needs of the community vegetable. The main obstacle was the cultivation of cabbage root disease outbreak mace (clubroot), which until now have not found an effective control techniques. Clubroot disease caused by organisms that resemble fungi : Plasmodiophora brassicae Wor. which was the soil inhibitant  and soil borne pathogen. Therefore, there must be a way to control environmentally friendly by using suppressive soil, find microbes antagonists related to the cabbage plant habitat in the soil. The results showed that the index of diversity both on suppressive and conducive soil of 1.2304 and 1.2811 respectively, and the index of dominance on the suppressive and conducive soil  were 0.6677 and 0.6838.  Prevalence micoflora of  the suppressive soil  amounted to 44.22 % and 43.06 % conducive soil all dominated by Fusarium spp. Microbial antagonist as a potential control of P. brassicae was Trichoderma sp . Based on the analysis in the suppressive soil as much as 171 x 103 cfu /g soil, higher than on the conducive soil to 90 x 103 cfu /g soil.
