Another beautiful week of weather but that may be coming to an end soon given the forecast but dare I say it we could do with some rain in some areas of the course as we are drying out.

I have mentioned the Poa annua (wintergrass) resistance before and the photos below give a very good demonstration of just what is happening.  The top photo is from 7R green post spraying and the bottom photo is 5W post spraying and they were sprayed on the same day and at the same rate.  We are currently ten days post application and the result looks quite ok on 7R but very poor on 5W.  The label says twenty one days plus for full effect to become apparent so I'm hoping 5W catches up.  They are different grasses in the greens obviously and a very different profile which may have an effect as the product is mainly taken up by the roots.

7R green some Poa circled.

 

5W  green some Poa circled.

With the slowdown in mowing requirements we have been able to allocate more hours to bunker maintenance and in particular raking.  But no matter how much time gets allocated to raking, if players are going to leave the bunkers as below then there's not much we can do.  

It really is up to the players?

A good friend of mine in the USA on a top 100 course used to say to his members "We can only rake the bunkers once a day....after that it's up to you."
