This isn't your grandfather's weed handbook. In fact, at 136 pages, Purdue University's Turfgrass Weed Control for Professionals might be best described as the mother of all weed guides.
This newly expanded guide provides weed identification and control information that turfgrass professionals can use to develop effective weed control programs for golf courses, athletic fields, sod farms, lawns, and other turfgrass systems.
Updated annually since its inaugural printing in 2012, the guide identifies a total of 105 weeds and contains more than 300 color images. It is available in hard copy for $20 or as a download for $12.
Authored by Purdue's Aaron Patton, Ph.D., and Dan Weisenberger, the guide also includes input from scientists in several other states, including Illinois, Iowa, Kansas, Kentucky, Michigan, Minnesota, Missouri, Nebraska, New York, Ohio and Wisconsin.
For each weed, the guide includes the scientific name and characteristics such as growth type, detailed physical description, habitat and favorable growth conditions, control options and similar weed types.
Other additions new to this year's edition include: a chart describing the label notes of postemergence crabgrass herbicides based on growth stage, modifications to the weed control efficacy tables. recommendations on herbicides for use on buffalograss as well as new information on herbicides and plant growth regulators.
