Abstract

Spraying sporals suspensions prepared from the antagonist’s cultivation of a Trichoderma harzianum strain on the seedlings of 24 tender wheat lines as a preventive treatment under controlled conditions, causes a decrease of severity for most lines towards the E1 strain of Septoria tritici compared to the control seedlings.
