The statement 'It is legal to mix two pesticides in a spray tank even if the combination is not listed on the label' is true or false.

• A. True
• B. Sometimes
• C. Depends on circumstances
• D. False

Answer: (D)

Tank mixing is governed by the label. You may mix pesticides in a spray tank only if the label for those products explicitly allows that specific combination or provides a compatibility indication with the other product. If the combination isn’t listed on the label, mixing them would violate label directions and FIFRA, and could lead to legal consequences as well as crop injury or other harm. To stay legal and effective, check the labels for any stated tank-mix allowances, compatibility notes, and the correct order of addition; if there’s no approval for the blend, don’t mix and consider applying the products separately or using a label that specifically permits the mix.
