Biological control activity of Trichoderma koningii and T. harzianum against Pythiura seed rot and pre-emergence damping-off of pea was increased by adding various compounds to seed treatments. Biological control activity of T. koningii was increased up to 48% while activity of T. harzianum was increased up to 44% by incorporating specific compounds into seed treatments. Compounds promoting T. koningii were generally ineffective in promoting biological control activity of T. harzianum. Organic acids were most promotive to the activity of T. koningii whereas polysaccharides and polyhydroxy alcohols were most promotive to T. harzianum. There was no relationship between the ability of the compounds to support in vitro growth and proliferation of Trichoderma strains in the spermosphere and increased biological control activity by the antagonist.
