    I'm always changing up my program based on weather and different products. This year I'm going to do a split app of pre this fall based on rocommendations from a local golf super and a turf professor I am going to do a slit app of simazine in October followed up by atrazine in December.

    So my question is hot hot is too hot for an application of simazine? My fall is going to be busy with fall seeding the end of September and our first born expect the end of October. I'm trying to get ahead while I can. All I can find on the label is to apply after sept 1

    In a perfect world the temps will cool off and I will be done seeding this month and can start pre apps oct 1.

    I'm starting in early Oct. I used to wait closer to Nov but the leaves start falling and get in the way. The weather is going to cool off later this week around here. As far as I know there aren't temp restrictions on Simazine.

    What are your concerns? I usually get pretty good control when I was doing 1 simazine app in November. Had some small Poa breakthroughs around the edges but they were cleaned up with spring pre app in feb.

    I'd say what I'm going to try will work pretty good at keeping things clean. It is coming from a turf professor at nc state and also the super at a pretty good country club.

    That seems normal to me but why do some use Atrazine and Simazine when there are other products that are not as bad for environment and cost effective as well? Not saying I don't use them but just wondering. Do they work better in cool weather than say prodiamine or Demension?

    Simazine or sim-trol is dirt cheap here.

    I started using barricade on my late summer apps. Next round I will be using Simizine which should start around last week sept 1st week of oct. Once that's done I usually follow up between thanksgiving and new years on any break through, onions, etc...

    Barricade is also not very strong on broadleaf weeds. To get the same coverage out of Barricade, Gallery would have to be added. There is now a virtual ban on simazine in my state. For winter month weed coverage, I use Dimension and Gallery. It goes away by the time the weather starts to warm back up. I do not want root pruners on the ground in the summer months. That is when the grass needs to recover from being kept in not quite dormant conditions over the winter months.

    Early on in the round I was spot spraying broadleafs. The last week or so I have been mixing bwc in the mix.
