A good way to prevent herbicide damage to plants because of residues left in the spray tank from a previous application is to limit the use of certain spray equipment to 'herbicide only.'

A good way to prevent herbicide damage to plants because of residues left in the spray tank from a previous application is to limit the use of certain spray equipment to 'herbicide only.'

• A. True
• B. False
• C. It has no impact
• D. Only if using certain herbicides

Answer: (A)

Cross-contamination from spray equipment residues is a real risk. Residues of an herbicide can cling to tanks, hoses, and nozzle parts and be transfered to crops later sprayed with different products. Keeping equipment used for herbicides separate from equipment used for other pesticides or for spraying non-target crops eliminates the chance of those residues causing injury, even if the same sprayer would otherwise be used. While thorough cleaning helps, dedicating equipment to herbicide applications provides the most reliable protection against residue-caused damage. This applies across a wide range of herbicides, not just a select few.
