Another month has flown by and September is now upon us. This month traditionally sees a shift in weather conditions, which become more autumnal, with less extreme heat and cooler temperatures, and more frequent rainfall. Mornings and night become noticeably darker and, importantly for turf managers, dew on the grass plant becomes a more regular occurrence.
August's weather has provided good conditions for those who have carried out any maintenance, with positive conditions to promote recovery. There has been a mixture of good temperatures with sunshine and showers which has maintained soil temperatures and provided plenty of moisture for germination after seeding.
September looks set to continue from August, with conditions still favourable for any renovation work planned. Therefore, those who couldn't get this work done in August will still have a good opportunity for success this month. These conditions will also continue to provide strong growth and recovery from areas with high play. If overseeding work is being carried out, ensuring good contact with the soil will allow the seed to utilise the moisture in the ground. Plant growth regulators such as Prohexadione-calcium and trinexapac-ethyl can be used at this time to help in the development of new seed by holding back the competition from existing mature plants in the sward, creating a more favourable environment for establishment.
As moisture levels increase in the soil and on the leaf, this favours disease development, as the 3 parts of the disease triangle start to come together. For many this will play a major part in planning over the coming months, alongside carefully selecting the right nutrition.
In this month's diaries we focus on how conditions become far more conducive for disease development, with heavy dews, less sunlight, more shade etc and how management of these stress factors becomes essential.
