Abstract

The #in vitro responses of three #Alternaria spp. isolates to 16 #biological control agents and eight fungicides were evaluated. A split plot experimental design was used, with a factorial arrangement for each pathogen. Factor A was to fungi isolates and Factor B to control agents. The mean comparisons were by Tukey test. The Alternaria spp. isolates were sensitive to Dicloran, Boscalid, #Cyprodinil-Fludioxonil, and #Tebuconazole fungicides, because they not allowed any develop of mycelial growth at 264 hours after confrontation. The biological control agents with the best fungistatic effects against to the isolates of Alternaria spp. were four Trichoderma agents, they significantly affected the mycelial growth at 264 hours after confrontation. There were other biological agents such as Bacillus subtillis, B. cereus, #B. megaterium (Rhizobac combi), #Trichoderma harzianum (Triko root) and Gliocadium virens (Soil gard), but with the lowest or null fungistatic effects.
