Abstract
One of the most important diseases of cucumber is Phytophora dampingoff caused by Phytophthora drechsleri Tucker.
This study investigated the potential for biocontrol of the disease using a single isolate of the fungal pathogen antagonist Trichoderma harzianum and compared the efficacy of the isolate with traditional chemical control methods.
Antagonism occurred through hyphal contact, coiling, vacuolation, and lysis.
Volatile metabolites of T. harzianum caused 86.6 per cent inhibition of fungal growth. T. harzianum was as effective against P. drechsleri in soil systems tests as most of the chemical treatments.
