| Abstract/Contents: | "Effects of plant growth regulators (PGR) (ethephon and trinexapac-ethyl), herbicides (dithiopyr, ethofumesate, and prodiamine), and fungicides (azoxystrobin, chlorothalonil, flutolanil, iprodione, propiconazole, and thiophanate-methyl) on the development of ryegrass blast were investigated. There were significant effects (P<=0.05) of fungicide and PGR/herbicide on blast disease severity (DS). There were also significant interactions between PGR/herbicide and fungicide. The PGR, trinexapec-ethyl, reduced DS when propiconazole and iprodione were applied on turf to manage the disease. The herbicides, ethofumesate and dithiopyr, increased DS when flutolanil was applied. There were no significant effects of herbicide and PGR on DS when azoxystrobin, chlorothalonil, or thiophanate-methyl were applied. This study indicates that use of the PGR, trinexapec-ethyl, may aid in ryegrass blast management. Conversely, the herbicides, ethofumesate and dithiopyr, may contribute to blast disease epidemics, especially when flutolanil is used to manage the disease." |
