Key Tasks for September
End of Season Renovations
After a long hot and dry summer, the end of August has proved to be somewhat text book in many areas of the country, with cooler temperatures, periods of rainfall and less intense sunshine all combining to increase soil moisture and instigate grass plant growth. Whilst this may seem like a return to normal, maximising recovery from a position behind where we would normally expect to be at this time of the year requires consideration and thought if surface quality is to be maximised ahead of oncoming reduced growth over the autumn and winter. A situation made all the more challenging due to the impact of recent legislative changes in the plant Protection Product market.
It is then, not an over exaggeration to state that September 2018, more than any other September in recent memory, is the month which will define the turf management year, with the three R’s of recovery, renovation and repair.
Soil Water Management
With increasing rainfall levels in many areas of the country, moisture is returning to the soil. However, aiding the penetration of that water away from the surface and into the soil profile via the combination of aeration and wetting agents with a high percentage of penetrant activity. This enables the perennial grasses, with their deeper root systems, to access water in good time and helps to stem the encroachment of emerging algae and moss, along with germinating weeds and Poa annua seeds closer to and at the surface. This is particularly important on surfaces which contain a greater percentage of thatch than is desirable, as these will be the most hydrophobic surfaces, actively repelling water absorption.
Once soil moisture levels have returned to optimum, then granular fertilisers will provide the optimum means of introducing nutrition into the profile by which to induce recovery. Try to avoid feeds which are heavy on ammonium as the nitrogen source, as this will produce a flush of growth which is then susceptible to fungal disease. Rather lower ammonium values, accompanied by urea and methylene urea, will provide a steady feed and consistent controllable growth.
Be aware that in optimum moisture and temperature conditions, granular fertilisers (which are made available to the roots via the soil water solution) will in the case of ammonium take between 5-7 days to induce a noticeable response in the plant, with urea coming online after 10-14 days. Methylene will then slowly become available over a period as long as 10-12 weeks dependent upon the ratio of short, medium and long chain molecules in the product.
Due to the traditional June spraying window being unsuitable for the application of herbicides, many areas will have gone untreated. Turf weeds such as Taraxacum officinale (common dandelion) are adapted to persist longer in a surface during drought conditions, in the case of this plant due to the deep tap root. Additionally, weed seeds on the surface of thin swards will germinate with the moisture provided by rainfall.
Consequently, September provides the last opportunity of 2018 for controlling weeds at a time when strong growing conditions persist, thus aiding the uptake, translocation and efficacy of selective herbicides. Undertaking this operation now will prevent weeds taking a firm foothold into next spring.
Now is the time to apply nematodes to areas for the control of leatherjackets and chafer grubs. This time of year represents the period when young juvenile larvae are hatching out and moving through the soil surface. Consequently, this is the time nature intended for the nematodes to predate upon the small juvenile grubs. Soil water levels need to be good before and for two weeks after application to allow the nematodes to swim to their prey and be effective. Facilitating their passage into the soil with a penetrant wetting agent is a useful strategy, as is sarel tine aeration immediately prior to application.
The newly approved chemical control Acelepryn is on an Emergency Authorisation which expires on the 20th September 2018. Releases of stock are dictated by strict Stewardship conditions which require each situation to have been assessed and authorised by a BASIS qualified advisor. The only authorised application areas are; airfields, race courses, golf greens and golf tees.
September heralds the arrival of worm season. There are no authorised chemical controls for worms. The only acceptable means of managing the issue are cultural ones such as brushing casts when dry or temporarily amending the surface pH via the application of substances such as sulphur. At a time of change which places new demands on turf managers to produce results and maintain standards, a raft of control options can become available, often these options are not labelled for the control of a particular issue however any substance applied with the intention of directly effecting, harming or deterring a pest is done so as a pesticide, and consequently is being done illegally if it is not registered with a MAPP number (Ministry Approved Pesticide Product) by the Chemicals Regulation Division.
Users should also consider the associated risks to the wider environment and ecosystem of any product which has not been subjected to the rigorous, scientific, independent testing standards.
Once moisture returns so does relative humidity; when humidity combines with stressed turf and warm temperatures, conditions are conducive to the growth of fungi. Consequently, a host of turf diseases can expect to be witnessed through into September.
However, 2018 is the first year without the curative activity of the fungicide iprodione, the active ingredient in Chipco and Interface. The only chemical options for turf disease are preventative systemic substances. Application prior to the observation of symptoms is vital in ensuring their success.
It is worth consulting the Turf Disease Triangle below and giving due consideration to what circumstances, conditions, maintenance practices and inputs on your site may influence each of the three factors.
Away from Plant Protection Products, such as fungicides, which directly target a virulent pathogen, thriving in a favourable environment, one of the most effective tactics available to the turf manager is to reduce the susceptibility of the host. In this regard, adequate water availability combined with appropriate and balanced base nutrition are further bolstered by the benefits of cell wall boosting and plant system enhancing calcium, phosphite and silicon.
Maintaining a cricket square requires regular mowing, so it is important to keep your blades sharp at all times. Backlapping will help prolong their lives, but they should be sent for re-grinding, with your bottom blade replaced at the same time, especially a shaver blade.
Check your ground for foreign objects, such as studs or stones which can cause considerable damage to machinery and pitch.
We are pleased to announce the launch of our new Grounds Training website, together with our new suite of online courses
There are two courses - Spring & Summer Maintenance and Autumn & Winter Renovations. New dates are currently being planned – Email Carol Smith using the below link to register your interest.
Each of the courses is also available in an ONLINE format. The Lantra accredited course in Cricket Pitch Maintenance is a series of training videos, each followed by multi-choice questions and answers. In addition to the videos, the accompanying comprehensive Course Manual is also included. There is a choice of courses - Spring & Summer and Autumn & Winter - more information.
Our Lantra Accredited Spring & Summer Cricket Pitch Maintenance Course is now available as an online course.
Now you can learn about how to maintain a cricket pitch in the comfort of your own home and in your own time. This newly developed course covers Spring & Summer Maintenance and consists of a number of videos with assessment questions, and an accompanying hard copy Course Manual. The Online Course is Lantra accredited and provides you with all the basic knowledge required to maintain a cricket pitch over the period stated. There is also the option of attending a one day practical course.
Pitchcare is the only provider of LANTRA accredited training courses in the maintenance of a Cricket Pitch.
We will also be running our regular one and two day courses at various venues during the year.
Delegates attending the courses and using the accompanying manuals will be able to develop their own skills, working knowledge and expertise, by understanding the method of instruction and the maintenance principles they set out. Included in the Course Manuals are working diaries showing the range of tasks needed to be accomplished each month.
The Course Manual is available for purchase separately.
We can also arrange Lantra accredited training on site to groups of 6 – 10 people. Email Carol Smith for information.
Structures: Check and repair fences, scoreboards, covers and sightscreens. Finish off any painting that may have been delayed due to bad weather.
Artificial Pitches: Keep all surfaces clean, by regular sweeping and brushing to remove any algae and moss from surface. Sand filled systems also require regular brushing to maintain manufacturer's recommendations for sand levels and pile heights.
Other work to consider:-
- Mark out boundary line or ensure rope is in place.
- Scoreboards are ready for use
- Erect security netting around buildings to deter balls from damaging properties.
- Ensure stumps and bails are correct size, yardage disks are available.
- Check sightscreens, covers and machinery as breakdowns could be time costly.
- Artificial netting facilities should be checked, cleaned and marked out ready for use.
