Irrigation improvements started today for hole #11.

 
We will be adding (6) sprinkler heads to the right of the 11th fairway. They will be placed in the rough right of the right side bunkers. This additional coverage will provide better watering results for the 11th fairway.

Relentless July and August Leads to Major Turfgrass Problems

16 August 2016

Turfgrass Disease Solutions, LLC

     Over the past three weeks, I have visited more than 65 golf courses in Delaware, Maryland, New
Jersey, New York and Pennsylvania and there is one common theme, stressed turf due to the relentless weather since mid to late July. The recent high day time temperatures, warm nights, humidity, intense sunlight, wind and then spotty thunder storms have placed incredible stress to all cool season fine turfgrass areas. The weather has not discriminated amongst private nor public clubs, high budget or low budget courses - every golf course is showing signs of stress in some regard. It has been a brutal season to try to maintain green speeds, manage moisture and playing conditions. Due to the varying climates, budgets, ages, and designs throughout the region, golf courses should not be compared to one another. The growing season of 2016 is bringing chronic issues such as air movement, drainage, shade and weak species to the fore front.

     The most common problem I have encountered, especially in regions that are receiving rainfall, is severe wet wilt to fairways, tees and greens. Wet wilt is a physical problem in which the soils are saturated and the grass cannot transpire water to cool itself because of poor air movement and high humidity levels. This has been most commonly observed in low lying areas of fairways, tees and greens. Most commonly, it is complete decline or the only live grass is in aeration holes from this spring or last fall. Wet wilt is very difficult to manage and can take up to 10 days to fully show up, especially on higher cut tees and fairways. Typically, you will see that golf cart tire tracks wilt quickly and then decline even when the soil moisture is adequate. If you are experiencing wet wilt, be conservative with mowing heights and use solid front rollers. Rolling greens is a significant stress to thin turf. On fairways, in the short term, limit cart traffic and restrict to roughs or paths. Don’t be afraid to preventively syringe turf that is showing signs of wilt with adequate soil moisture. Long term, explore options to improve drainage and air movement.

     Dry wilt is also a problem for many golf courses not receiving rainfall in some regions. This places an incredible load on the staff to manage moisture with hoses and overhead irrigation, which is tough in the heat. If you are in a dry period, be sure to check that irrigation heads are properly functioning. Far too often an irrigation problem shows up when the stress shows up and with the heat we have experienced, it’s a slow road to recovery. Beyond lack of water or too much water, is decline in the poorest growing environments. Air movement is the most important growing environment consideration during warm, humid periods. Air movement is needed for fine turf to be able to cool itself following light applications of water (i.e. syringing). If there is no air movement, the turf in that environment can be 8-12F warmer than turf receiving air movement naturally or through fans. Fans have completely changed greens management in areas where trees and underbrush cannot be removed. Air movement is the key for syringing to work. If the turf does not dry in between syringing, the effects are minimal and the turf will begin to thin.

     Mechanical stress is showing up throughout the region, especially in shaded areas. Mechanical stress, although self-inflicted, is tough because superintendents are trying to produce a playable golf course. The two most common mechanical issues I see are roller damage to the collars or mower stress from turning or to the edges (clean ups) of greens. Be sure to watch staff turn mowers and use rollers to be sure they are properly completing the task and adjust heights if mowing is skipped. Skipping mowing may be needed during droughty or wet conditions but if skipping mowing, be sure to assess the height of cut and not remove too much tissue in a single mow. You will be able to work the height back down in time, but the initial scalp can cause issues under the current environment.

     Disease pressure has been extremely high and every major turfgrass disease has been observed. Brown patch and Pythium pressure has been high for the past three weeks. For those of you maintaining perennial ryegrass, I have confirmed gray leaf spot over the past week- this disease can be incredibly damaging under stress. In some of our trials, we are seeing tighter spray intervals and high rates work best but nothing will provide 100% control in extreme conditions or saturated, humid conditions. Preventive fungicides should be applied as needed. If curative control is attempted, be sure to have the disease properly identified and use the best course of action. Annual bluegrass weevils have been significantly damaging bentgrass fairways and tees for the past 3 weeks. We have found early instar white grubs in some of the untreated plots in our research trials so be sure to scout for them if you are seeing wilt or unthrifty turf. Be sure to scout for insect pest and treat accordingly.

     In a quick outline, these are just a few of the major observations I have had in my recent visits.
Other common themes include: elevated amounts of phytotoxicity (injury from commonly used plant
protection agents), elevated plant parasitic nematode levels, physical injury from aggressive golf shoes
and damage from venting or spiking greens and/or sand topdressing on weak and/or stressed turf. For
those of you considering aerification in the near future, please assess the health of the turf before aeration
or use a less aggressive technique. Aeration should not be looked upon as a tool to renovate weak turf,
but rather a tool to promote long term health. Aerification of weak turf in August can lead to weak turf in
September and October which are two of the most important golf months in the Mid-Atlantic region.

Due to greens aeration, backnine holes will be closed today.

Due to grees aeration golf course will be closed today.

With the hot weather we have experienced over the last week, aeration procedure will be limited today. We will still be aerating greens but will be conservative on how many we do. The entire golf course will be closed all day today.

Summertime Bermudagrass suppression in action.

                      Bermudagrass:
                     Where did it come from and why do we still have it?   
 
     In the 1950's Whitemarsh Valley CC brought in common Bermuda-grass to ensure green fairways in the summer. The irrigation systems of the day were inadequate to supply the proper coverage for the existing grass. For the next 30 years the club enjoyed dense fairways in the summer and fall but put up with the thin lies in the spring.
     The club decided to change over to Bentgrass in 1994 after a brutal winter killed all the Ryegrass and Poa annua on the fairways. The plan was to spray roundup (non-selective herbicide) to remove all Bermuda, Ryegrass and Poa annua from the fairways only while keeping the rough playable during the grow in of the Bentgrass. This plan succeeded in the fairways but over the years the un-effected Bermuda-grass in the roughs tillered their way into fairways. At this time there are not any products that can outright kill Bermuda-grass and not harm Bentgrass. In  2012 a product came out that actually suppresses Bermuda-grass while being relatively harmless to Bentgrass. This is where we are at today, constant suppression during the summer months and reduced Bermuda-grass the following year.                                                    
 

This is a view of the 10th fairway after treatment of the Bermuda-grass suppression product. It causes the tips of the effected grass to turn white which sticks out compared the green color of the fairway.
 
This is a closer look at common Bermuda-grass while in the suppressed state.
 
 

This is a real up close look at what is going on. Over the past 4 years we have made real head-way in reducing the total Bermuda-grass population on the course, with further reduction expected in the future.
