| Abstract | ||||
| Eighteen fungi were isolated from peanut seeds (Arachis hypogea L). Fusarium oxysporum, Fused= solani, Sclerotiurn rolfsii, Macrophomina phaseolina and Rhizoctonia solani were the most frequently isolated fungi and had the highest percentages of incidence. During the two seasons of 1995 and 1996, five fungicides were tested against root rot and wilt of peanut, as seed dressing and soil treatments. Rizolex T 50% was the best fungicide in reducing disease infection in both seasons, under greenhouse and field experiments, followed by soil treatment with chlorotosep and Amconil. The lowest total yields were obtained with Topsin M which was the least efficient in reducing the percentage of disease infection in peanut seedling. Moreover, Vitavax Thiram and Rizolex T were the more efficient to reduce the percentage of pod rot infection against all the tested isolates under both artificial and natural infections. | ||||
