| Abstract/Contents: | "Postemergence herbicides (2,4-D, 2,4,5-TP, MCPP, dicamba) influence the severity of Drechslera sorokiniana leaf spot on Poa pratensis. Exposure of herbicide-tolerant P. pratensis to spray or soil applied herbicide at 10-12, 10-9, 10-6 and 10-3M primarily stimulate disease. Disease increases on progressively older leaves and the auxin-analog herbicides seem to enhance senescence processes in older leaves, predisposing them to more severe attack. Disease is further enhanced on older leaves and decreased on younger leaves by herbicide combinations. This response may be related to potential auxin effects on senescence processes in young and old leaf tissue. The herbicides decrease total sugars, have little effect on amino acids, and increase ethylene content of leaf tissue; these factors may effect pathogenesis. The potential field response of leaf spot to fall applied herbicides is probably influenced by photoperiod." |
