Abstract

Sheath blight caused by Rhizoctonia solani is one of the important diseases in corn. A study on the effect of arbuscular  mycorrhizal  fungi in controlling  sheath blight disease was conducted at pilot project scale in Jambangan Village, Malang District. Three-replicated treatments were arranged in a split-split plot design. The results   showed that highest attack intensity occured at treatments without inoculation of  arbuscular mycorrhizal fungi. The mean of attack intensity for Wisanggeni variety  was 70,05%, while that for GM 30 line was 73,79%. The attack intensity at Wisanggeni variety inoculated with arbuscular mycorrhizal fungi was 45.39% to 49.46%, while that at GM 30 line was 47.52% to 56.12%. The infection of sheath  blight disease reduced the production in terms of knob part and seed  weight even  though the plant was inoculated with arbuscular mycorrhizal fungi of Glomus sp. or  Acaulospora mellea. The reduction of knob weight at Wisanggeni variety was 14.2% to 15.0% and that of seed weight was 21.4% to 23,0%.  At GM 30 line the reduction of knob part was 12.0% to 17.2%, while that of seed weight was 19.1% to 20.4%.
