Pesticides may be tank mixed with fertilizer if allowed by label directions.

Pesticides may be tank mixed with fertilizer if allowed by label directions.

• A. Always
• B. Only if the label directions permit
• C. Never
• D. Only with a separate permit

Answer: (B)

Tank mixing pesticides with fertilizer is something you may do only when the product label allows it. The label is the controlling instruction for any tank mix, so you must follow what it permits, including any restrictions on crop type, growth stage, rates, order of adding components, and required compatibility testing. If the label permits mixing with fertilizer, you can proceed as directed; if it doesn’t, you must not mix. This protects against chemical incompatibilities, crop injury, reduced efficacy, or environmental risk. The idea that you can always mix, or never mix, or need a separate permit isn’t correct—the rule is determined entirely by the label.
