Notes:
As part of the registration requirements for bioherbicides in Canada. Colletorihum gloeosporioides (Pen.) Penz., and Sace. f. sp. malvae (C. g. malvae). a naturally occurring pathogen on Malva pusilla Sm. (round-leaved mallow), was tested under controlled conditions for its effect and disease developmeiu on ten non-target crops: oilseed rape, flax, entil, mustard, saf-flower. sugar beel sunflower, wheat, okra and cotton. All crops except okra and cotton were also tested in the field at Regina and Indian Head. Saskatchewan, When applied at 12 times the recommended field rate (120 × 106 spores m-2), this fungus was shown to have no adverse etfect on yield or plant development under controlled or field conditions on any of the crops or crop cultivars tested, except in safflower Safflower was susceptible under controlled conditions and under field conditions the cuttivar 'S-208’showed significantly lower biomass in treated vs. untreated plots in one of threer growing seasons. Therefore, this fungus is not recommended for use in safflower, but can be safely used as a bioherbicide in the other crops tested under field coitditions. C. g. malvae was registered as the first bioherbicide in Canada in 1992.
