Two formulations of the herbicide 2,4-D (2,4-dichlorophenoxyacetic acid) - the butyl ester (BE) and the propylene glycol butyl ether ester (PGBEE) -- had 96-h LC50's to cutthroat trout and lake trout ranging from 490 to 1,200 microgram/liter in static tests. A third formulation -- the isooctyl ester (IE) -- was not toxic to cutthroat trout or lake trout at concentrations below 60.000 microgram/liter. The butyl ester (2,4-D BE) was slightly more toxic than 2,4-D PGBEE, and the toxicity of both esters increased as water temperature decreased.
Golf Course Management & Construction presents a comprehensive summary and assessment of technical and scientific research on the environmental effects of turfgrass system construction and maintenance. Although the book focuses on golf courses, it also discusses turfgrass systems for residential and commercial lawns, parks, and greenways. The book is an excellent introduction to the concepts of nonpoint source environmental impacts of turfgrass management for turfgrass scientists and specialists, landscape and golf course architects, turfgrass system and golf course developers, golf course superintendents, environmental scientists, and land-use regulators.
