Abstract

The effect of urea NITROGEN FERTILIZER and sodium nitrate on the growth of fungus Trichoderma koningii compared with two species of FUSARIUM CULMORUM and F.GRAMINEARUM causal agent of wheat head-blight disease. In this investigation various parameters such as comparison of the colony growth, SPORE PRODUCTION and chlamydospore in a single and dual cultures studied. In addition, the effects of urea nitrogen and sodium nitrate on the fungal colony growth were measured by colony diameters in single and dual cultures. Mycelial colony growth rate of Trichoderma under effect of urea fertilizer in 1g/I and 2g/I was significantly increased when compared with two species of F.culmorum and F.GRAMINEARUM. But this growth rate in nitrogen condition significantly decreased by Trichoderma, when compared with control. While both species of Fusarium in the above condition showed significantly (P<0.05) an increase on the fungal growth rate when compared with control. Species of F.culmorum with increasing of urea fertilizer concentration significantly increased in growth rate of mycelial in comparison with control 48h after incubation. Application of urea on chlamydospore production by Trichoderma indicated a significant reduction seven days after culture. But, had a little effect on macroconidia reduction of F.culmorum. But neither species of Fusarium produced chlamydospore on urea media nor in 1gr or 2gr per liter. Trichoderma koningii in both conditions of amended media with urea fertilizer and sodium nitrate was able to parasitize both species of Fusarium.
