Pre-emerging

As we live in a tropical climate, our soil temperatures are warmer than many other golf courses which results in not only increased growth but also increased weed pressure. Every 8 weeks, we apply what is known as a pre-emergent herbicide to almost the entire golf course and we will be finishing the golf course today. Once applied the herbicide creates a film in the top of the soil so that when a weed seed germinates and comes in contact with this film, it adsorbs the herbicide and is killed before it becomes visible - hence the term 'pre-emergent'. Given our 5 days of winter this year, we started our pre-emerging in August instead of typically September. We will continue this programme now right though to around April/May.
