How much active ingredient is there in a 20lb bag of Atrazine 90DF?

To determine how much active ingredient is present in a 20-pound bag of Atrazine 90DF, it's important to understand what the "90DF" designation means. The "90" indicates that 90% of the formulation is the active ingredient, while the remainder consists of inert ingredients.

To calculate the amount of active ingredient in the bag, multiply the total weight of the product (20 pounds) by the percentage of active ingredient (90%). This calculation would look like this:

[ 20 , \text{lbs} \times 0.90 = 18 , \text{lbs} ]

This means that out of the total 20 pounds of Atrazine 90DF, there are 18 pounds of the active ingredient. This correctly reflects the nature of the formulation and is crucial for accurate application of the product in pest control. Understanding this concentration is essential for making informed decisions regarding dosage and effectiveness when using any pesticide formulation.
