| Abstract/Contents: | Presents a study conducted "to evaluate the impact of two irrigation regimes (light and frequent nighttime vs. deep and infrequent morning) and three commonly used chemicals (Daconil Ultrex, Trimmit 2SC, Primer Select) and various tank-mixes of these materials on dollar spot in fairway-height creeping bentgrass." Details the materials and methods used in the study, stating that "eight independently irrigated blocks, 9.8 feet x 34.4 feet (3.0 meters x 10.5 meters), were oufitted with pop-up irrigation heads that delivered 5.7 gallons (21.6 liters)/minute to each block." Reports that for 2002 "soil moisture averaged 15% in the infrequently irrigated plots on July 10, 2002, and dollar spot developed in these plots on July 19." Reports that for 2004 "a significant irrigation effect...was not observed until [August] 24 when soil moisture averaged 23% in infrequently irrigation plots." Concludes that "maintaining moisture levels above 25% (that is, above the wilting point) for this soil in late summer when severe disease outbreaks occured can reduce dollar spot severity and improve the ability of Daconil Ultrex, Trimmit 2SC and Primer Select to suppress the disease in fairway-height creeping bentgrass." |
