Dollar Spot and Gray Leaf Spot Severity as Influenced by Irrigation, Chlorothalonil, Paclobutrazol, and a Wetting Agent

Abstract: Creeping bentgrass [Agrostis stolonifera L. var. palustris (Huds.) Farw.] and perennial ryegrass (Lolium perenne L.) are commonly grown fairway grasses that are susceptible to dollar spot (Sclerotinia homoeocarpa F. T. Bennett; DS) and gray leaf spot [Pyricularia grisea (Cooke) Sacc; GLS.] diseases, respectively. This field study assessed the influence of two irrigation regimes (light and frequent nighttime versus deep and infrequent morning irrigation) and six chemical treatments including: chlorothalonil (te… Show more

“…In some arid regions, water repellency has become so bad that agricultural production is impossible without costly amelioration (Roper 2005). In other regions of the world, water repellency occurs to a lesser extent, but its management with wetting agents has been shown to increase crop yields (Crabtree & Henderson 1999) and reduce the impact of diseases (McDonald et al 2006).…”

“…Across the three sampling timings, all the tested microbial groups, with the exception of actinomycetes, showed a general trend where stable populations were maintained between October 2015 and May 2016, and then the populations increased significantly in October 2016, regardless of the wetting agents applied. It was known that moisture and temperature can be limiting factors for soil microbial growth due to constrained uptake of C and N [33][34][35][36]. Compared to 2015, October 2016 had an average temperature of 16.6 • C, higher than 14.4 • C in October 2015 ( Figure 2).…”

“…Surfactants are chemical compounds whose molecular structure is well suited to overcome both the water repellent and poor infiltration characteristics. Wetting agent is a surfactant that is used by substrate industries in order to break the surface tension of water, improve the speed of wetting and retention of water [6][7][8][9]. Currently, wetting agent is commonly mixed in growing media to greatly improve their water absorbing ability.…”
