K-State Radio Network “Plantorama” – Home Lawn Winterkill

Posted on by jahoyle

(By Jared Hoyle, KSU Turfgrass Research and Extension)

HOME LAWN WINTERKILL– It was a fairly harsh winter in this region.  And that has homeowners wondering if their lawn grasses were adversely affected by the extended cold and wet conditions. K-State turfgrass specialist Jared Hoyle says while the likelihood of outright turfgrass winterkill is relatively low, some limited damage may have occurred.

Control of Turfgrass Diseases

Posted on by jahoyle

“Turfgrasses under intensive management are often subject to outbreaks of infectious diseases. Diseases usually are most damaging when weather or cultural conditions favor the disease-causing agent but not plant growth and vigor.”

http://www2.ca.uky.edu/agcomm/pubs/PPA/PPA1/PPA1.pdf

This quote from the “Chemical Control  of Turfgrass Diseases 2017” publication at University of Kentucky and Rutgers University, really sums up why we have diseases in our turfgrass systems.  Many times we have no control over weather or the cultural conditions that favor disease-casuing agents and those same conditions do not favor turfgrass growth.  To prepare for 2019 download this publication from Drs. Vincelli, Clark and Munshaw and keep it around as a great reference.  I keep a copy of this publication along with my weed control manual (https://blogs.k-state.edu/turf/new-turfgrass-weed-control-for-professionals-2019/) at all times.

Yellow Woodsorrel (Oxalis stricta) Control

Posted on by jahoyle

(By Jared Hoyle, KSU Turfgrass Research and Extension)

Yellow woodsorrel (Oxalis stricta) is a perennial or annual broadleaf weed that has clover-like trifoliate heart shaped leaves.  Yellow woodsorrel most commonly spreads by seeds that are contained in a capsule that when it explodes ejects the seeds.  It can be confused with clover but has yellow flowers with five petals.  You can find this weed in a wide range of soil conditions and can commonly be confused with black medic, birdsfoot trefoil and white clover. A similar species is creeping woodsorrel but it is most commonly found in landscape plantings while yellow woodsorrel is most commonly found in turf.

To control oxalis, herbicides that contain triclopyr and fluroxypyr are very effective.

 

 

 

 

Herbicides that contain fluroxypyr include;

  • Battleship III
  • Escalade 2
  • Momentum FX2
  • Tailspin
  • Vista XRT

Herbicides that contain triclopyr include;

  • 2-D
  • 4-Speed XT
  • Battleship III
  • Chaser
  • Chaser 2 amine
  • Confront
  • Cool Power
  • Eliminate
  • Horsepower
  • Momentum  FX2
  • Tailspin
  • Three-Way Ester II
  • Turflon Ester Ultra
  • Turflon II amine
  • Triclopyr 4
  • TZONE

Always remember a healthy turfgrass stand through proper maintenance is the best weed control and can help minimize oxalis in your turfgrass.

White Clover Control

Posted on by jahoyle

(By Jared Hoyle, KSU Turfgrass Research and Extension)

School is starting back and college football is right around the corner.  This tells me it is the best time of the year to start renovating, overseeding or establishing new cool-season turfgrass areas. But before you do that, you might have some unwanted weeds to get rid of.  White clover is one of the most common weeds found in cool-season turfgrass.  It can grow in a wide range of environmental conditions and can tolerate many of our cultural practices.   It can also spread by seeds and by stolons.

White clover is a perennial broadleaf weed that has trifoliate leaves that may or may not have a wedged-shaped mark. Although it is called white clover the flowers are white but may turn pink as they age.

Because white clover can fix its own nitrogen some see it as an important species to add beneficial soil nitrogen.  There had been some work done to explore using both clover and turfgrass in a mixture in their lawns.  Others may consider it as a weed.

If you consider it a weed, fall is a great time to try and control it.  But did you know 2,4-D, glyphosate and sulfentrazone do not control white clover?  For best control herbicides that contain clopyralid, dicamba, fluroxypyr, florasulam, metsulfruon, and/or quinclorac (also controls crabgrass) provide the best control when applied in the fall.

Always remember a healthy turfgrass stand through proper maintenance is the best weed control and can help minimize clover in you turfgrass.
