Winter Injury Recovery Woes, Challenging Rough, And Pest Activity

winter injury on putting greens continues to be frustrating for superintendents
and golfers. Patience is necessary until more consistent soil and air
temperatures develop, which will improve turf recovery.|
common topics have dominated the discussions during Course Consulting Service
visits over the past two weeks. Unfortunately, slow recovery from winter injury
has continued to frustrate golf course superintendents and golfers at many
courses in the region. Temporary putting greens remain at many golf courses.
Although these are never popular, temporary putting greens should not be
abandoned until the putting greens are fully healed. Watch the USGA Green
Section webcast Assessing
Winter Injury and Promoting Turf Recovery in the Northeast Region for
information regarding the best management practices for promoting a rapid and
sustainable recovery from winter injury on putting greens. The Green Section Record article Winter Damage is an excellent reference for
information on why putting greens experience injury and how to best limit
cool weather coupled with ample rainfall this spring has made the rough
challenging for middle and high handicap players at many courses. Increased
mowing frequency and even plant growth regulators have been used to combat the
rapid growth of rough. Lowering the mowing height may offer some relief, but
this adjustment will also increase the turf’s susceptibility to drought stress
so caution is advised.
bluegrass weevil damage and anthracnose disease have both been observed at
courses recently. Careful scouting for annual bluegrass weevils is very
important to ensure insecticide applications are made when and where necessary.
Golf course superintendents battling anthracnose disease should review the Golf
Course Management article Best Management
Practices for Anthracnose on Annual Bluegrass Greens and make
adjustments as necessary. Increasing the mowing height, applying 0.1-0.125 lbs.
of nitrogen per 1,000 sq. ft. every seven days, and light and frequent sand
topdressing combined with regular fungicide applications are often the most
impactful changes to combat an anthracnose outbreak.
