0 October 2021 Pitch Diaries

We end September with what seems like more rainfall in the last few days of the month than we have seen over both August and September combined. Although looking back, there have been a few days of significant rainfall in these months, however this rain at the end of September feels much needed as there has been very little over the past weeks and most places are looking significantly dry, certainly for the time of year.

Looking ahead at the forecasts, the unsettled end of the month carries on into the start of October. Although further into October appears more settled, those with renovations planned in early October may have to consider the option of drier but cooler conditions slightly later, or wetter but warmer soil temperatures slightly earlier.

As weather conditions change, October can be a high disease pressure month. Cooler temperatures, with increased leaf and soil wetness, mean that it's important to constantly monitor the local environmental conditions with a view of the site's previous history and patterns in disease outbreaks; knowing which areas are key indicators can help massively to stay ahead of damaging disease outbreaks. As conditions become more conducive for disease development, being aware of historic turf responses to certain weather conditions form a central part of an Integrated Pest Management (IPM) approach.

For many, the focus this month is Microdochium nivale (microdochium patch) control. There may still be some signs of the increasingly present Anthracnose, but as maintenance practices alter, raising heights of cut, reduced mowing etc… many of the stresses that contribute to this disease are eased slightly. Conditions in October can be ideal for Microdochium nivale outbreaks, and predicting when these outbreaks may occur is challenging. Gaining an understanding of what contributes to disease pressure reaching tipping point on your own site allows better informed decisions when selecting and timing any of the applications aimed at counteracting disease pressure. These may be fungicidal, nutritional or plant response applications.

In this month's diaries we focus on fungicide technology and how a shift in your approach to nutrition should follow the change in temperatures. As well as advice on leatherjackets and worms.
