Abstract
The effects of soil amendment with rapeseed meal from Brassica napus cv. 'Dwarf Essex' (high glucosinolate concentrations) and 'Stonewall' (low glucosinolate concentrations) on the biological control activity of Trichoderma harzianum towards Sclerotinia sclerotiorum and Aphanomyces euteiches were evaluated. Trichoderma harzianum added to soil reduced myceliogenic germination of S. sclerotiorum by 94%, but did not affect carpogenic germination. In contrast, 100% reduction in carpogenic germination was observed in soil amended with Dwarf Essex meal, along with a 33% reduction in myceliogenic germination. With Stonewall meal as soil amendment, carpogenic germination was reduced by 44% and myceliogenic germination was not affected. Both Dwarf Essex and Stonewall meals inhibited colonization of sclerotia in soil by T. harzianum, from 100% to 0% and 8%, respectively, so that biocontrol activity of T. harzianum was reduced in the presence of either meal. Aphanomyces euteiches root rot of pea was significantly reduced by T. harzianum alone (100%), by amendment with Dwarf Essex meal alone (77%), and by T. harzianum in combination with Dwarf Essex meal (100%). Amendment with Stonewall meal alone did not control root rot, and combination of Stonewall meal with T. harzianum reduced the biocontrol efficacy of T. harzianum.
