We use Talstar, I prefer it over the XTS as the label signal word is lower being caution instead of warning. Talstar if bought by the case of 4 3/4 gallons is very cost effective at about $120 a case. FMC typically runs a buy three get one free promotion. I think that Talstar mixes better than the generic as well, add some spreader sticker (Very Important) & your good to go.
Its good to keep some Cyzmic CS on the truck as well in case you get a call back. The label on Talstar restricts its use to every 28 days when applying at the high rate of .06%. The cyzmic CS costs a lot more, but if only used for call backs it can go a long way. It is micro-encapsulated & does a great job.
Altosid is a great product, customers feel safer knowing that its label permits application to animal drinking troughs & its safe for aquatic life. Its very cost effective and has a long shelf life as well.
Remember that the mist blower uses air to apply the chemical & you can go farther with it than if using a conventional spray rig, however it is not Ultra Low Volume. I had a guy tell me he was mixing 40ounces of chemical per gallon because he could cover an acre with that gallon, this is not the correct way. Follow the label instructions & treat the SR-450 sprayer as you would any other sprayer when mixing. You will exceed the label recommendations of one ounce per 1000sq ft but will have great results doing so all while using less product. You will apply 1 ounce in a gallon to about 2-3k.
I highly suggest reading this article in its entirety, http://www.pctonline.com/Article.aspx?article_id=38451
. This is a published article from PCT on university research conducted in 2005 about mosquito spraying. It details the procedures, the chemicals used, the results (from testing as well as customer perception), & tells you everything you need to know on how to do the job correctly & safely.
Hope that helps!
