Per page 8 of the product label you would need to mix 3.0 fl. oz. of product per gallon of water and spray upper and lower leaf surfaces and between fruit clusters and on small limbs and trunks
to the point of runoff where pest appear. Repeat applications as necessary up to a total of five times per year for small fruits, but not more often than once every seven days.
We cannot find anything on the product label that mentions the 2 qt/acre application so we are unsure where that information came from.
