Improving Expectations Of Snow And Ice Management Services: Reducing Risk

By Phil Harwood, MBA

One of the ways to reduce risk is to have some extra capacity. How much extra capacity is enough? What is optimal? Some extra capacity is desirable, but not too much.

The Major League Baseball’s (MLB’s) Cleveland Indians provide a good example of too much unused capacity. With only 45.6 per cent of the capacity of Progressive Field used in 2012, the Indians have the lowest attendance in MLB based on capacity use. (There were, however, two teams actually over 100 per cent capacity use for the entire 2012 season: the Philadelphia Phillies at 100.8 per cent and the Boston Red Sox at 101.4 per cent.)

A Driving Force On The Course: Inside The Industry

By Molly Doyle

McGarvey belongs to the Western Canada Turfgrass Association (WCTA) and Golf Course Superintendents Association of America (GCSAA), but he says he is most connected to CGSA. Currently a member of its Professional Development and Research Committee, he was also president in 2003. He says one thing he likes to do during the winter is attend the annual CGSA conference.

As for being named Superintendent of the Year, McGarvey has earned this recognition before in 2006 by the British Columbia Golf Superintendents Association (BCGSA). However, he says the CGSA honour is an even bigger thrill for him.

Improving Expectations Of Snow And Ice Management Services: Building Flexibility Into Capacity

By Phil Harwood, MBA

There are many ways to build flexibility into capacity calculations. One proven strategy is to hire subcontractors, as they allow an operator to increase his or her capacity without buying additional equipment. To eliminate assumptions, it is important to clarify what equipment each subcontractor has available to dedicate to him or her, what production rates are to be expected, and in what geographic areas the subcontractor operates.

Some contractors take the position of capacity being unlimited due to a perception subcontractors are readily available. In this author’s experience, selling work beyond capacity without having subcontractors lined up ahead of time is risky business. One needs to understand there is uncertainty inherent in the unlimited-capacity approach. Most snow and ice professionals want to reduce their risks, not increase them.

Reconstructing The Derrick Club: Back To The Derrick

Tastes in golf course architecture are subjective. There will inevitably be a hole (or three) at the new Derrick Club course some golfers will consider too difficult, and, of course, a few others will criticize as being too easy. There is no way to stop this, as people are always going to have different opinions on golf holes (and courses). However, this is a good thing—without criticism, an art form like course design cannot advance and flourish.

The inevitable criticism of certain holes and specific features at the new course will not bother me when all 18 holes open for play in the summer of 2015. However, I will be disappointed if the new course does not genuinely provide golfers with a sense of place that clearly suggests there is indeed only one Derrick Club.

Using Plant Defence Activators To Control Turfgrass Disease: Conclusion

By Tom Hsiang, PhD, Paul H. Goodwin, PhD, and Alejandra M. Cortes-Barco, M.Sc.

Regarding the activity of the defence activator Civitas, the conclusions found were:
● minor direct effects on fungi;
● suppressive effects against diseases in lab and field tests;
● primes defence response genes for greater and faster expression after infection; and
● relies on an ISR-based mode on gene expression analysis when compared to gene expression after application of butanediol—a known ISR activator.

A wide and diverse range of compounds can activate SAR, ISR, and other forms of induced resistance. These compounds may be naturally occurring in plants or microbes or can be entirely synthetic compounds that affect some part of pathways which are involved in functions ranging from the detection of pathogen-produced molecules by receptors on the plant cell membrane up to factors that bind to deoxyribonucleic acid (DNA) and affect expression of defence-related genes in the plant nucleus.

While the list of activators continues to grow, it remains a challenge for disease management to adapt these compounds into practical materials for commercial use. Important desirable qualities for their practical application are similar to those of synthetic fungicides, such as:
● stability;
● shelf-life;
● consistency;
● cost; and
● ability to perform under various favourable and unfavourable conditions.

However, as more defence activators are discovered, the probability increases that some will have the qualities needed to replace or complement the current pesticides being used against plant pathogens.
