Substrate incubation time after fungi inoculation in the control tomato seedling damping-off

The use of fungi the genus Trichoderma spp. for control plant diseases it has proved to be an important and promising tool, mainly tomato crop production system, however, there are difficulties in establishing bioagent. This work aimed evaluate effect substrate incubation time after inoculation with harzianum damping-off seedlings. experimental design was completely randomized, consisting six treatments four replications. two times doses T. (0 10 days [DIST] 1.0 or 5.0 g harzianum) controls (control inoculated not Rhizoctonia solani). variables analyzed were incidence damping-off, area under disease progress curve, percentage emergence, emergency speed index, average time, germination coefficient, total fresh mass, root length (cm) height part (cm). containing have proven R. solani growth
