[caption id="attachment_1081" align="aligncenter" width="4608"] The role of Dew removal has a huge impact on disease populations through pressure periods[/caption]In my last blog I spoke about the speed disease populations can increase at during conducive conditions and how you can use fungicides to help zero out that population. The more I look at disease management the more I separate out fungicide usage and Integrated Turf Management (ITM), not because they are unrelated (they both have important parts to play) but I'm beginning to see them like this:
- Fungicide - Zero out the disease population
- ITM - Slow the rate of development
- Thatch / Fibre levels
- Grass species
- Dew removal
- Airflow
- Drainage
- Light
- Plant Health / Correct nutrition
- Thatch / Fibre levels - The lower the amount of thatch, the less viable the spore population is so the slower the start of the disease process..
- Grass species - the more resistant a grass species the slower the march of disease.
- Dew removal - the less time moisture is on the leaf the less time disease has to spread through it.
- Airflow - The higher the airflow the drier the leaf blade.
- Drainage - The better the drainage the drier the sward.
- Light - The better the light levels the stronger the grass plant, the better chance of survival.
- Plant Health / Correct nutrition - managing a happy centre ground allowing the plant to cope with disease but not be overly susceptible is vital.
