Canada to approve Koppert biofungicide Trianum

Date:12-10-2014

The Canadian Pest Management Regulatory Agency (PMRA) proposes to register Koppert Biological Systems’s biofungicide Trichoderma harzianum strain T-22, end-use product Trianum WG and Trianum G for the suppression of soil-borne pathogens. T22 is a beneficial fungus that out competes plant pathogenic fungi for space and nutrients, colonizing the plant roots ahead of the pathogens. Trianum can suppress various root diseases caused by Rhizoctonia solani, Fusarium oxysporum, Pythium ultimum, P. aphanidermatum, P. violae on greenhouse crops, field crops and greenhouse ornamentals as well as reducing symptoms of dollar spot (Sclerotinia homoeocarpa) and microdochium patch (Microdochium nivale) on turf. Trianum WG is applied as a suspension, while Trianum G Biological Fungicide is mixed directly into the substrate.
