sorry but I cannot tell you much about dazomet from experience but Corey is correct about cutting corners.
The club down the street from us finally decided to upgrade their greens and renovate. they did everything except treat them during the process. and now they are paying dearly with bad greens less than 2 years after the project. they even closed their course for a month in order to try to grow them back in. while they blamed several different issues such as Nematodes and disgruntled employee, the biggest issue was not treating the greens during the project. they had large dead spots well before the recent issues and had trouble growing areas in. I try to stay away from their course but always get feedback from my own members and some of theirs.
Think of it this way, treating the soil basically kills everything. you start over new!
Not treating the soil leaves the chance for issues down the road. these issue may end up costly. so much so that the long term treatment of them can cost 10 times more than the original application would of. these issues can mean the difference between you sleeping well at night or not.
Ask yourself honestly, is the original contour of your greens that great that you would risk the issues! in a lot of cases changing the contour by small amounts can make your greens even better. think of this, if you want to deal with green speeds between 9-10, a little more contour makes them better. if you want speeds between 10-12 less makes them better, 12 or more nothing makes them better (just kidding). My greens have a lot of slope to them so I can cut them between .130 and .150" with no complaints.
you really need to till them and treat them!
