Is tank mixing allowed?

Is tank mixing allowed?

• A. Yes, unless prohibited
• B. No, it is never allowed
• C. Only with written permission
• D. Only for non-public water systems

Answer: (A)

Tank mixing means combining two or more registered pesticides in the same spray tank for a single application. The fundamental rule is to follow the product labels, because labels are the binding instructions for use. If the label does not prohibit mixing and the products are physically and chemically compatible, you may mix them. Always check each label for any restrictions, compatibility notes, and required sequencing, and verify there are no limits on rates or reentry intervals when mixing multiple products. Before mixing, do a compatibility check (a jar test) to ensure the products play well together and won’t clog equipment or cause adverse crop injury. Also confirm that the total use does not exceed label rates and that any required adjuvants or drift-reduction measures are compatible with the mix. In short, tank mixing is allowed unless the label specifically says not to, or unless there are regulatory or compatibility blockers.
