New Bio Solution to Leatherjacket and Chafer problems in fine turf

Adult Cranefly (Daddy Longlegs)

Leatherjacket damage on bowling greens has been a huge problem already this year, so it is with a bit of relief that I am adding a new biological leatherjacket and chafer grub treatment to the shop today.

Introducing Harmonix® Tri-Nema™

Chafer grub and leather jacket infestations within your turf not only cause damage by their presence, but they also encourage further destruction by enticing predators like Crows and Starlings to their location, who in turn can cause untold losses to a healthy and vibrant surface whilst feeding.

This is why Bayer have helped to develop and patent Harmonix® Tri-Nema™, to give you 3 different modes of activity in one Nematode treatment.

Turf Condition is all importantNematodes target pest larvae

Not only do Chafer Grubs and Leatherjackets destroy great turf by feeding on healthy roots, but the presence of their predators can also have a negative effect on the performance characteristics of the surface. This can negatively impact your organisation in terms of reputation, financial and the welfare of customers and animals alike.

Large infestations and presence of these predators can be a very costly experience within the environment of the turf you are caring for. From unsightly playing surfaces and course closures to potentially dangerous running surfaces, the potential for costly problems is always a large consideration.

Harmonix® Tri-Nema™ has three answers to the one question of how to effectively control these problems…

Turf Grass Rigidity. Performance Evaluation of the Bowling Green Part 8.


In measuring the performance of the bowling green there are visual and functional factors to consider. Now that we've studied the visual clues we move on to the functional ones in earnest. Today we will look more closely at what at first might seem a strange quality of turf and that is Rigidity. This property of sportsturf is closely associated with the physiology of the individual grass plants we looked at in an earlier series and also with bowling green performance, as it influences green speed and trueness.

Turf Grass Smoothness and Colour. Performance Evaluation of the Bowling Green Part 6.


In the performance evaluation of the bowling green there are visual and functional measurements we can make to ascertain the likely performance of the green. Colour and Smoothness are the last two visual components we need to look at before moving on to the functional attributes we can measure. On the face of it, colour and smoothness seem like fairly innocuous elements to focus on; almost too obvious you might say. Let's see if they are more important or even different to what we previously thought.

Turf Grass Growth Habit. Performance Evaluation of the Bowling Green Part 5.

Annual Meadowgrass

So far in this series of articles on the subject of bowling green performance we have used some of the common visual clues to assist in our evaluation of the turf. Today we'll break from that to dig a little deeper into the physiological aspect of the different turf grass species that influence what we see on the surface. Turf Grass Growth Habit can play a big role in the ultimate performance of the bowling green. so let's get started on indentfying the main differences.

Turf Grass Uniformity. Performance Evaluation of the Bowling Green part 2.


The Performance Evaluation of the Bowling Green we embarked on last time relies on our ability to appraise a range of factors. Some of these are purely visual, while others are functional and can be quantified more readily. The trick lies in gaining the experience to merge the visual data with likely performance traits. Good old fashioned greenkeeping and the greenkeeper's "feel" for the turf are still as relevant as they've always been. Today we get started on the process of evaluating bowling green performance.

Performance Evaluation of the Bowling Green

By far the best selling of my eBooks available on this site is Performance Bowling Greens; it out sells all of the others by 10-1. Bowling green performance can seem a bit sketchy and hard to tie down to any sort of measurable parameter, but that's more to do with the lack of a joined up approach to the subject in the industry than it is a lack of measurable components. This article introduces the subject of the Performance Evaluation of the Bowling Green.
