I am considering the use of Drive 75 df on a lawn with a bad crabgrass problem , the lawn is predominant KY blue/red fescue/rye mix. Cool season grasses in Wisconsin. Plenty of moisture this time of year so timing issues are not a problem. I have read the label but I still have a question. The label states that it is more effective if you use a MSO along with the drive. First of all is it necessary to use a sticker? I currently have a jug of a product that is called Chem-Stik by Precision labs and I am not sure if it qualifies as a MSO. I looked on CDMS and it is not listed. The jug states that it is a non-ionic spreader sticker. I have used it with Millennium Ultra as it came recommended from the dealer for this use but Drive is not a popular control here and the dealer was not sure if the Chem-Stik is approved. I do not have the Drive in my posession yet so I can't do a jar test. The main ingredients in the Chem-Stik are Emulsifiable Polyethylene + Alkyl Phenoxy Polythoxy Ethanol 26% Does anyone know if this would work as an approved mix before hand? If not what do you recommend? I do not have a Lesco around so that won't work. Another question, I will be applying .86 team pro and 20-3-5 fert tomorrow. I plan on spraying the drive in early May. Are there any issues with spraying a post M on a lawn that has been treated with pre-M granular? Also, what are your experiences with drive 75 positive or negative and do you have any tips for me?
