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.
