The Effects Of Turf Compression On Plants Growth Regulator Efficacy, William Lyle Petersen
The Effects Of Turf Compression On Plants Growth Regulator Efficacy, William Lyle Petersen
Masters Theses
A 150kg lawn roller was used in combination with various Plant Growth Regulators (PGR) (Embark & Event, Event & Oust, Embark & Oust, Escort & Oust, Telar & Oust, Event & Balan, Oust & Balan, and Balan) to evaluate its affects on the growth rate of rough turf at the Coles County Airport. The rolled plots were evaluated for height, reduction of seedheads, phytotoxicity, and weed control. Rolling was of no significance to treated or untreated turf. PGR combinations containing Oust were significantly better at reducing turf height than combinations lacking Oust. PGR combinations lacking Oust discolored turf significantly less …

Leaching Of An Acetanilide Herbicide, Cp55097 In Soil Columns, Regina K. Higgins
Masters Theses
The leachability of the acetanilide herbicide, CP55097 was determined using a soil column system. This herbicide, which is used as a preemergent against certain grasses and broadleaf weeds, was leached through four different soils (sandy clay, sandy loam, sandy clay loam and clay loam) using the following procedure. Plastic columns consisting of 8 rings (2 in. dia. x 1 in.) were assembled and their bottoms covered with cheesecloth. They were then filled with soil and prewetted with water to attain field capacity. Herbicide concentrations equalling 0, 1, 3, 6 lb/A were pipetted onto the soil surface and 0, 1, 2, …
