Spring Pre-Emergent Application on the Dye Course

During the course closure on Wednesday March 13^TH, the Agronomy Team was able to get out and apply a granular pre-emergent herbicide on a fertilizer carrier to all of the fairways, approaches, and 419 Bermudagrass roughs.  Oxidiazon or Ronstar was the tool of choice for control of summer annual weeds such as crabgrass, goose grass, and many of the other summer weeds that we battle here in the lowcountry.   This application was carried out by the team over the course of the day and is an integral part of our weed control strategy, so application is very important to make sure there are no misses or over applied areas that could result in either poor weed control or damage from to much herbicide.  This application needs to be watered in heavily to move the herbicide off of the fertilizer carrier and activate it into soil profile, therefore we watered heavily immediately after the application and again heavily the night of the application.  Tuesday the day prior to application we received approximately a ¼” of rain which already had the course in a damp condition.  With the watering of the herbicide on Wednesday, conditions on Thursday may be a little more damp than we would like but the timing of this application is crucial based on soil temperature and we are at the end of the window for application. Play should be affected minimally and the course will dry down and be firm again by the weekend.
