Interaction between<i>Trichoderma</i>species and<i>Armillaria</i>root rot fungus of tea in Kenya

Abstract

Abstract The interaction of 11 Trichoderma isolates against Armillaria root rot fungus of tea was investigated. Most isolates significantly inhibited the growth of Armillaria. The highest inhibition was noted with one of the isolates of T. koningii, T. longibrachiatum and T. harzianum. The isolates with highest inhibitory properties tended to produce a pigment into the nutrient broth. The implications of these results in view of the future management strategies of Armillaria root rot of tea in Kenya are discussed.
