   Asulox kills goosegrass in fairways, tees and roughs, and it kills whatever wide leaved monocot weed is the one that we can't kill anymore since MSMA is gone. (Can you tell me definitively which weed this is?) Why is there so little interest in this pesticide? I hear, "It is too expensive to label it." It is already labeled for turf and ornamentals, just not golf courses. I don't care 10X the price, but give me legal access to it for golf turf. Or might there be another way to get a temporary label until the answer comes?

   Scott,
   
   Last I heard Asulox was taken off the market for Turf(golf courses, residential and commercial, but not sod farms) and Ornamentals due to the active ingredient, Asulam, having significant residual in soil or clippings when collected. This dates back to the 90's. Was some awesome stuff for Crabgrass control in St. Augustine.
   
   If the weed you are referring to is Bull Paspalum, look at Celsius. I have seen it take it out after two applications.

   Have used Asulox forever. Old product and will kill lots of things. Used it extensively in the sod business and the golf course as well in certain locations. Does a wonderful job killing Johnsongrass.

   I'm in Australia and trying to find out a little more on Asulox and it's history in the US.
   
   Each label I've seen has sod farm only. Has it ever been registered for turf in the US? If it has been, why is it not now and only sod farm? I've had a look on the EPA website but can't find anything clear.
   
   Thanks in advance.
   
   Brett.

   Asulox does not degrade very rapidly. The use on residential and commercial turf was pulled basically because they were finding the a.i. in clippings that had been harvested and piled many months, even years, prior, mostly due to the fact that many landscapers and golf courses collect and stockpile clippings. This led to elevated levels of the a.i. in that particular spot.
   
   In Florida, the loss of Asulox led to many problems in the residential market basically because it was the only product that controlled Crabgrass in St. Augustine. With the recent swing in turf varieties being installed to now more and more Zoysia, there are other options available and the turf industry hasn't really missed Asulox that much.
