| Abstract/Contents: | "The effect of lime (99, 198, 396 kg CCE ha-1) in combination with the acidifying fertilizer ammonium sulfate (AS; 196 kg N ha-1 season-1) or the alkalinizing fertilizer calcium nitrate (CN; 196 kg N ha-1 season-1) on the severity of summer patch (Magnaporthe poae) in `Georgetown' Kentucky bluegrass was evaluated in the field from 1995 to 1998. Fertilizers were applied alone and in combination with lime or elemental sulfur (845 kg S ha-1). Disease severity was greater on turf that received CN than AS. Compared to CN alone, CN plus lime (396 kg CCE ha-1) enhanced symptom expression, while the addition of sulfur to CN reduced symptom development in 1998. Although turf treated with AS plus sulfur sustained low levels of summer patch in 1998, the combination resulted in extremely poor turf quality. Compared to AS alone, the application of AS plus lime raised soil pH but did not increase disease severity. Thus, lime may be applied with AS, to maintain acceptable soil pH levels, without reducing the effectiveness of AS for the control of summer patch in Kentucky bluegrass." |
