Title

EVALUATION OF TRICHODERMA ISOLATES FOR BIOCONTROL OF FUSARIUM WILT OF MELON

Pages

  39-57

Abstract

 Five isolates of TRICHODERMA (T. virens DAR 74290, T. harzianum T39, T. harzianum M,T. viride and TRICHODERMA sp.96) were evaluated for biocontrol of FUSARIUM WILT of MELON (Fusarium oxysprum f.sp MELONis). Dual culture and cellophane overlays techniques were used in vitro assay. Colony area was recorded, compared with controls and percentage inhibition of growth was calculated. Greenhouse experiments were performed to test the efficacy of Trichderma isolates for BIOLOGICAL CONTROL of FUSARIUM WILT of MELON. Colonized wheat bran with TRICHODERMA and infested wheat grain with pathogen were incorporated to potting mix as a rate of 10 and 14g per Kg respectively. Percentage of plants surviving determined 30 days after planting. Percentage of growth inhibition varied significantly among the antagonist isolate (P<0.01) and ranged from 0 to 100%. Cell free metabolite of T.virens DAR 74290 completely inhibited growth of the pathogen in vitro and appeared to be fungicidal. Percent of plants survival in pots treated with antagonist or healthy control was 100 and those of TRICHODERMA + pathogen varied from 5.3 to 61.06%. Population (cfu/g) of pathogen was stable and population of TRICHODERMA slightly decreased during the greenhouse experiments.
