| Abstract/Contents: | "Although the application of acidifying fertilizers can reduce the severity of summer patch disease, this benefit must be balanced against the need to maintain a satisfactory soil pH level for plant growth. This field study was conducted from 1995 to 1998 to evaluate the application of lime (99, 198, and 396 kg CCE ha-1) in combination with the acidifying fertilizer calcium nitrate (196 kg N ha-1 season) on the severity of summer patch, caused by Magnaporthe poae Landschoot and Jackson in 'Georgetown' Kentucky bluegrass. The two fertilizers were applied alone and in combination with lime or elemental sulfur (845 kg S ha-1). On some rating dates, disease severity was greater on turf that received calcium nitrate versus ammonium sulfate. Compared to calcium nitrate alone, calcium nitrate plus lime (396 kg CCE ha-1) enhanced symptom expression, while the addition of sulfur to calcium nitrate reduced symptom expression in 1998. Although turf treated with ammonium sulfate plus sulfur sustained low levels of summer patch in 1998, the combination also resulted in extremely poor turf quality. Compared to ammonium sulfate alone, the application of ammonium sulfate with lime raised soil pH but did not increase disease severity. Thus, lime may be applied along with ammonium sulfate, to maintain acceptable soil pH levels and turf quality, without reducing the effectiveness of ammonium sulfate for the control of summer patch in Kentucky bluegrass." |
