Pre and Post Emergent Spray Kicking In

We started our pre and post emergent spray 10 days ago. We are seeing some results of the glyphosate product that we sprayed. Here is a Poa Annua plant that was not sprayed before the picture was taken. 

Here is another Poa Annua plant that was sprayed 7 days before this picture was taken. Notice the shriveled up leaves and the yellowing of the plant. 

This last picture is a little hard to see, but here is one of our largest patches of Poa Annua on the course. This area is in front of #8 green. You can see the right half of this patch was sprayed 10 days ago and is almost completely yellowed out and dead. The left half was sprayed today. The reason for splitting the patch is because it is right on the edge of our tree line where we had to spray Ronstar instead of Specticle for turf health reasons (see previous blog post). And it is also good to have a check plot to see if your chemicals are actually working. 

We will wrap up our spraying tomorrow.
