I am using a 16 gallon Northern Tool 2.2 GPM sprayer with CYFLUTHRIN POWDER for chiggers but find the instructions confusing. Would you please confirm that one level spoonful per gallon of water is the correct mixture.
Sorry for the confusion but there is no doubt; the labels that come with our products are many times confusing to say the least. The CYFLUTHRIN LABEL you are asking about is definitely inconsistent with how the mixture is presented. Here is what they mean…
If you are using the scoop that came with the jar, it should be a 5 gram quantity that can be held at one time. 5 grams would be about 1/6 of an ounce. That means that for light infestations, you would use 1/6 oz per gallon per thousand sq/ft of turf or about 44 scoops per acre. At this rate you’d be able to treat up to two acres of turf.
For your sprayer, add 16 scoops and treat 16,000 sq/ft when treating a light to moderate infestation. For heavy populations or what is typically consider to be a “major” problem as explained in our CHIGGER CONTROL ARTICLE, use it at the 2 scoops per gallon per thousand sq/ft rate. This means it will take the whole 1 lb jar to treat an acre.
