A practical measure to avoid damage from residues is to limit spray equipment to herbicide-only.

• A. True
• B. False
• C. It depends on tank size
• D. It depends on spray pressure

Answer: (A)

Prevent crop injury from residues by avoiding cross-contamination of spray equipment. When equipment is used for different products, tiny amounts can cling to the tank, hoses, and nozzle screens and transfer to the next application. Those residues can injure sensitive crops or cause unpredictable effects even after the original product is finished. Using equipment dedicated to herbicides minimizes this risk because it keeps the entire spray system free of residues from other pesticide types or tank mixes. Thorough cleaning between uses is still important, but dedicating equipment to herbicides is a practical, straightforward way to reduce residue-related damage. Tank size or spray pressure don’t address residue carryover and thus don’t provide the same protection.
