Is this what lies hidden beneath the calmness of the golf course greens? Man’s tenacious enemy on turf is grubs or beetle larvae. Learn how to find out about these hidden enemies and study ten special management techniques prescribed for golf courses on how to keep the putting green perfect for the entire year.
It is never an easy task to keep a golf course looking so green and perfect or to stop an army of grubs from destroying it with their eating appetite. Those small harmless-looking larvae might be rather dangerous since they can ravage fairways turning them into a motley of brown and bare patches almost in the blink of an eye.
To effectively eliminate these sneaky pests and guarantee that the greens are perfect, you need to know the right ways of dealing with the issue and come up with the most effective grub control strategies that get rid of them in a way that targets the source of the problem. The following article will bring out the top ten strategies that every groundskeeper must have in their wake of combating grubs and maintaining the face value of the golf course greens.
What Are Lawn Grubs?
Although most people are familiar with the term lawn grubs, these are actually beetle larvae. Beetles have larvae that dwell in the soil and feed on grasses, belonging to several different species. These grubs can cause significant damage to greens especially if the golf course green is well maintained.
How to Identify Lawn Grubs
Early detection is important for effective grub control. Here are some signs of grub activity on a golf course:
Wilting turf:
Turf areas that look scorched or appear to be dry even with appropriate irrigation could possibly mean grub infestation.
Dead patches:
There are some symptoms that would help one identify if their lawn is affected by grubs; these include the presence of brown or yellow patches of the turf.
Increased bird activity:
Some birds such as the crow and the grackle revel in surface grubs that are just barely hidden. An increase in these birds on the greens could mean a grub issue.
Soil sampling:
The practice of taking soil samples at different times of the season and analyzing them to determine the presence of grubs will give the correct answer.
10 Effective Strategies for Grub Control
1. Monitor and Detect Early:
These pests are best controlled by using regular monitoring to help detect them early and prevent them from re-infesting the lawns. This ensures that the damage is prevented before it gets out of hand. Soil sampling and visual observation of the greens are some of the some of the suggestive methods.
2. Cultural Practices Can Make a Difference:
Some cultural practices might make the grub environment slightly less favorable, or perhaps more effective. Core aeration offers benefits such as better drainage and an increase in the supply of oxygen in the ground, which may deter egg-laying females from selecting a site. As for other preventive measures, proper water management most importantly irrigation, the correct application of water, and avoidance of water stress can also be suggestive in reducing grub activity. Hence, DTE Golf® recommends for its client to adopt some cultural practices that are essential for the growth of the turf. Such practices may involve, efficient watering, suitable soil management, notably the right way of aeration because it is essential for drainage and root growth.
3. Beneficial Nematodes:
These are small roundworms that are commonly found in soil; however, some of them are parasitic to grubs. These nematodes can be applied to the turf, which is not only an innovative way of controlling grubs in specific areas but also a biological one. Also, investigate the possibility of using these fungi as biocontrol agents, especially for environmentally sensitive areas. DTE Golf® explores the potential of incorporating beneficial nematodes into one’s integrated pest management (IPM) program for a sustainable and eco-friendly approach to grub control.
4. Entomopathogenic Fungi:
Some fungi work as biocontrol agents that help to control pests such as grubs as they have an inherent ability to kill them. The concept of this paper then is to look into the feasibility of using these fungi as a biocontrol agent, especially in areas that are environmentally delicate.
5. Controlled Insecticides Still Remains a Tool
Usage of insecticides is common on golf courses for regulating grubs. But, it is important that one chooses the right one from the list that has been compiled above. Various insecticides are used to treat different types of grubs, therefore, it is important that the right type is used depending on the grubs that are infesting a certain area. It is also important to take note of when they are applied. Find out the window period most suitable for management to target specific grub life stages (eggs, larvae, or adult worms). Further, opt for insecticides that are least likely to harm these beneficial insects and pose a minimal threat to the entire ecosystem.
6. Consider Perimeter Treatments
It is common to find grubs Crickets and other insects attacking the greens from other areas. Identify the potential advantage of creating a barrier through the use of insecticides on or around the outer edges of the putting surfaces. This can be used to curb the establishment of new populations of pests in other areas.
7. Integrate and Rotate Strategies
For long-term deleveraging control, it may be useful to use different varieties of methods. Integration of cultural practices, biological control, and selective insecticides as the best option for developing an effective IPM. Also, as a strategy of mitigating the hoe of resistance, insecticides should be used interchangeably on grub.
8. Maintain Detailed Records
Monitoring records and records of measured control, as well as the effectiveness of such control, must be documented in detail. It can also be beneficial in decision-making in the present as well, in order to better understand grub behavior in the forthcoming seasons and potentially detect trends over time. DTE Golf® suggests that the type and timing of the control measures deployed, and comments made on grub activity and the state of the turf are recorded. It can be especially helpful in monitoring changes, the cycles of pleading shapes of grubs, and particular aspects of soil control in a given year.
9. Seek Professional Help:
Information concerning the specific type of pest to expect in any region and the recommended course of action can be most helpful and this can be obtained from professional turfgrass consultants or entomologists. That is why their help can be useful for the creation of a special grub control program compatible with the conditions on the territory of the Golf Course.
10. Stay Informed!
There are always new changes in the industry of turfgrass management. Staying informed of the current literature, advancements, and recommendations for grub control enables the application of the current optimal strategies and chemicals.
