| Abstract | ||
| Greenhouse and field experiments were conducted in 2003 and 2004 to . study the effect of growth regulators, which included Indole Butyric acid (IBA), Cycocel (CCC) and Gibbrellic acid (GAJ) at 50, 100 and 200 ppm in reducing of peanut root rot and compared to fungicides treatment. All tested growth regulators clearly affected on the incidence of damping-off, wilt and root rot disease, under greenhouse and field conditions Indole Butyric acid (ISA) followed by Cycocel (CCC) at 200 ppm were the most effective treatments in reducing peanut infections with damping-off, wilt and root rot, while treatment with Gibbrellic acid (GAJ) at 200 ppm recorded the highest infection compared to other treatments. There were positive relationship between increasing the concentration of ISA and CCC and their effect on incidence of damping-off, wilt and peanut root rot, while with GAJ this relationship was negatively. All tested fungicides and commercial biocides reduced percentage of damping - off, wilt and peanut root rot diseases and consequently increasing percentage of healthy survival plants, Vitavax-Thiram followed by Rhizolex-T recorded the highest effect in reducing camping-off wilt and root rot of peanut under greenhouse and field conditions. This study clearly showed that there is no clear differences between the efficacy of growth regulators and fungicides effect in reducing peanut root rot diseases especially with the damage effect of fungicides on the environment. | ||
