    2.5 gallons of trimec 992 to 250 gallons of water. Sound about right? Midwest, (assortment of different weeds and grass types)

    depends on how many gallons you are spraying per thousand sq ft

    I want to spray as little as possible. 2.5 gallons to 250 gallons works well at killing weeds but I'm wondering if I'm wasting it at all

    According to label it calls for 1.1 to 1.5 fl oz per gallon which covers approx 1000 sq ft in cool season grass applications. So if you go with 1.3 oz per gallon and do a little math... 128 oz per gallon. So divide 128 by 1.3 you get... 98.46ish. Multiply that by your 2.5 gallons you get 246.15. So you're pretty right on there.... So with your 246.15 gallons you can spray 246,150 sq ft, or 5.65 acres.

    And if you have Trimec Classic Like I use around my house since I do not spray other persons properties and do not have proper mix 1 oz per gallon and that treats 250sqft. so the one gallon you buy treats 32,000 sqft of cool season and warm season grasses. For St Augustine or Centipede grasses you still mix the same rate but coverage is twice as much... ie less chemical per area.

    Of course always check the labels on your own chemicals cuz my information is about as accurate as what I get off of websites...and we can all believe everything we read on the internet...

    he never really said the rate he's applying at. I'm definitely no mathematician but the rate he is applying at is gonna make a big difference. He could be spraying at 2 or 3 gallons per minute for all we know.

    Right. Very true. I was just giving up the information that comes on the labels. You're still only able to legally apply 1.5 oz per 1000sq ft of chemical, no matter how much water its diluted with though, correct? And then theres a max amount of chemical per 1000sqft per year as well, right?

    At 320 ounces per 250 gallon tank full is 1.3 oz's per gallon of water. You will have to put this gallon out over a thousand square foot of area and cover 250,000 square feet or 5.7 acres.
    I am using Vessel at 2 GPM or per 1,000 sq.ft. on 100 gallons. I think the concern for you is the over spray caused by forcing a gallon out over a 1,000 sq.ft. Z-sprayer and nozzles closer to the ground work best for this app.
    The matter is not applying over 1.5 ounces per M at one given time in 5 to 220 gallons of mixture per acre is mandated.

    992 stinks.

    It's the smelliest weed control I ever used. Once.
