~~Timing is based on Southern CT/Metro NY~~ Manage, Sedgehammer...Its all Halosulfuron & it's the best Nutsedge tool we've ever had. But only when it is applied to young actively growing plants in June. I get more applicators crying they aren't getting control yet they start buying product in July & August. When I scold them about their lousy timing the response is always the same..... ...The customer didn't see it until now. So what were YOU doing in June? Since when do customers know when to control weeds? Isn't that why they hired YOU in the first place? Jeez! We arent plumbers. So here is the plan for our Southern New England & Metro New York LCO's...While you still remember which lawns have Nutsedge & where it is on the lawn...Make a notation in your Outlook email program right now. If you're still "old school" , go buy a 2007 calendar. Make an entry for June 4th, 2007. That's a Monday & Nutsedge should just about be breaking the canopy between mowings. Thrus/Fri are the big mowing days so by Tues/Weds the application window is wide open. List who needs the applications & where on the lawn. If you aren't already using property maps you have all winter to get your act together. TELL (don't ask) the clients over the winter when you're doing renewals that you have this new program that will eliminate their Nutsedge problem & TELL them how much it will cost. Very few customers will require more than a gallon so charging by the minute or the gallon applied isn't rocket science. I've treated Nutsedge infested test plots with halosulfuron on 14 day intervals. In June we get nearly 100% control & no new plants the following season. By July, we killed the traget plant but a ring of new plants appear the following season about 4-6" from the prior years target. The later we get in the season the more likely we see the "ring of new plants" around the killed target the following year. Hence we can deduce that by July the plant has made new nuts which are not dying & will reappear the following season. If job security is the goal maybe we should be weighing the chances that repeat treatments (year over year revenue) also increases the risk of cancellations.
