Which dosage is correct for corn earworm?

• A. 50 ml.
• B. 5 ml.
• C. 15-20 ml.
• D. 100 ml.

Answer: (B)

Understanding dosage means knowing how much product to mix per unit of spray to get effective pest control without unnecessary risk. For corn earworm, the amount you apply is dictated by the product label, which defines the exact dilution to use—usually expressed as milliliters of product per liter of spray solution (or another specified unit). The labeled rate is chosen to balance killing the larvae with minimizing crop injury, residue, and environmental impact.

The 5 ml amount aligns with the typical labeled rate for this pest with the product in question, giving enough active ingredient to affect newly hatched corn earworm larvae while staying within safe, effective limits. Using much larger amounts—such as 15–20 ml, 50 ml, or 100 ml per liter—does not improve control and can increase the risk of phytotoxicity, non-target effects, and residue concerns. It also wastes product and may violate label directions.

Always follow the exact label instructions for the specific product you’re using, and calibrate your sprayer to deliver the labeled rate consistently.
