What is a tank mix?

• A. A single pesticide in the tank
• B. A combination of two or more pesticides or a pesticide and another product in a single spray tank
• C. A pesticide mixed with fertilizer only
• D. A pesticide applied in a separate spray tank

Answer: (B)

A tank mix is when you combine two or more products in a single spray tank for one application. This can mean mixing a pesticide with another pesticide or with another product such as a liquid fertilizer, adjuvant, or spreader—as long as the label allows the combination and the products are physically compatible. The idea behind a tank mix is to apply multiple active ingredients or additives in one pass, saving time and reducing the number of trips across the field. However, it requires checking label permissions, compatibility, and proper mixing order to avoid problems like reduced effectiveness or crop injury.
