Using some antagonists in controlling peanut pod rot infection in Beheira and Sharkya governorates during two growing seasons 2002 and 2003 revealed the superiority of Trichoderma harzianum followed by Chaetomium bostrycoides and Giliocladium penicilloides than each of the other tested commercial products i.e. Rhizo-N, Plantguard and Multi-VAM (mycorrhiza) in reducing peanut pod rot infection. Also, all the tested antagonists i.e. Trichoderma, Chaetomium and Gliocladium or those in commercial formula (Rhizo-N, Plantguard and Multi-VAM) increased the yield of pods in the two governorates. Meanwhile, all tested fungicides reduced peanut pod rot infection to percentages much lower than those of un-treated ones during the two seasons. The fungicides, Vitavax-T, Sumisclex and Rizolex-T were the best, followed by Benlate, Balear, Noplit, Daconil and Clorocip which had a moderate action while, Daconil was the least tested fungicide in reducing peanut pod rot infection during the two growing seasons in Beheira and Sharkya governorates. In addition, Rizolex-T was the best followed by Vitavax-T and Sumisclex in increasing peanut pod yield in most cases of treating during the two seasons. On the other hand, the integration between fungicides and fertilizers (NPK) at certain sowing time controlled effectively the pod rot infection and increased the total peanut pods more than any individual treatment whether in South-Tahrir or in Abou-Hammad.
