Description

This document reported the findings of a research project that examined how to reduce phytotoxicity associated with organosilicone surfactants used to control fairy ring disease in turfgrass. It described the nature and scope of fairy ring caused by Marasmius oreades, outlined the research objectives, and documented greenhouse and field experiments that assessed cultivar sensitivity, application methods, environmental conditions, and repeated surfactant use. It presented results on turfgrass injury, growth responses, and disease control effectiveness across different cultivars and management scenarios. The document concluded with implications for turfgrass management in Alberta, particularly for golf courses and lawns.

Description

This report outlines effective methods for controlling quack grass, a persistent perennial weed that significantly impacts agricultural land in Alberta. It details identification features to distinguish quack grass from similar species and presents various control strategies. The document describes both tillage methods, such as shredding and drying out rootstocks, and chemical control options using herbicides like TCA, Dalapon, Monuron, Atrazine, Bromacil, and Paraquat, for different scales of infestation. It also provides guidance on follow-up practices and specific considerations for control in shelterbelts and during lawn preparation.
