| Abstract/Contents: | "Phoma macrostoma Montag. was registered as a microbial bioherbicide for broadleaved weed control in turfgrass in Canada in 2011. A granular formulation is used to broadcast this fungus to soil whereby it grows towards the plants, infecting the roots and releasing phytotoxic macrocidins which are lethal to several broadleaved weed species. It was hypothesized that temporal soil temperature could affect growth of P. macrostoma, which in turn would alter the efficacy of weed control. Phoma macrostoma was grown on PDA plates at a range of temperature regimes between 5/5 and 38/38 ° C (day/night) to measure the radial growth for 14 days. These plates were then used in an inoculum-mat bioassay to determine efficacy (% chlorosis and % weed reduction) against dandelion seedlings. The experiment examined the effects on four fungal strains at 11 temperature combinations with four replicates, and was conducted twice. Radial growth, chlorosis and weed reduction was much lower at temperature extremes (5/5, 15/5, 15/10 and 30/30, 38/38 ° C) than at moderate temperatures (15/15, 25/5, 25/10, 30/5, 30/15. 25/25). The data suggest that the temperature optima to maximize the efficacy of P. macrostoma are in the moderate, temperate range. Applications outside of this range may reduce the level of weed control." |
