| Abstract/Contents: | Discusses potential methods of controlling root-infecting fungi. Explains that "turfgrass roots are relatively poorly understood...necrotic ring spot (Ophiosphaerella korrae) and summer patch (Magnaporthe korrae) were grouped in with other pathogens in a disease known as Fusarium blight...[Researchers] now know that each of those pathogens is in fact its own disease, causing similar symptoms on the same hosts but in different environmental conditions." Suggests that "the obviouis answer to many of the root disease infections is to alter cultural practices to optimize root health. This would allow the plant to withstand a minor to sometimes moderate infection because there are a greater number of roots to offset those colonized by the pathogen." States that "necrotic ring spot is similar in many ways to take-all patch, with the main difference being the host species: take-all patch attacks mainly creeping bentgrass and necrotic ring spot attacks mainly bluegrasses and fescues. But the timing of infection is nearly exactly the same as take-all patch, with active infection happening in the spring and fall of the year and symptoms becoming present in the hotter and drier conditions of summer." Suggests that fungicides "should be applied at full label rate and watered into the root zone to locate the fungicide near the point of infection." Concludes that "applying fungicides will not guarantee...a summer free of root diseases. But proper fungicide application timing, coupled with proper cultural practices, will at least give [turf] a fighting chance." |
