Date of sowing, preceding crop, soil amendment and microelements
nutrients were used as agriculture practices for controlling damping-off,wilt and
peanut root rots under greenhouse conditions. Sowing peanut seed at 15^thMay
was the best date which gave the highest significant increase in the survival
plants earlier of sowing led to increase in damping-off where delaying sowing
date after 15^thMay caused increase in wilt and peanut root rot diseases. Flax
as preceding crop followed by both of garlic and rapeseed recorded the lowest
percentage of damping-off, wilt and peanut root rot diseases while, faba-bean
as preceding crop gave the highest percentage of damping-off, wilt and peanut
root rot. Gypsum and sulphur had an important effect in reducing of damping -
off, wilt and peanut root rot diseases and increase of gypsum and sulphur
concentration was accompanied with decrease of damping-off, wilt and root rot
infections. The microelements nutrients and their concentrations play an
important role in reducir.g d'3mping - off, wilt and peanut root rot diseases
incidence, microelements mixture (Cu, Fe, Zn, and Mn) at 200 ppm followed by
copper sulphate at 200 ppm gave the best effect on reducing of damping - off,
wilt and peanut root rot diseases.
