Which dosage is a correct range for alfalfa looper control?

• A. 10-15 ml.
• B. 25-30 ml.
• C. 15-20 ml.
• D. 30-40 ml.

Answer: (C)

Understanding the right dosage means following the label’s rate for the pest and crop. For alfalfa looper, the label provides a specific window that delivers enough active ingredient to effectively kill the larvae while staying within safe limits for the alfalfa and the environment. The 15-20 ml range sits right in that approved window, offering a good balance of efficacy and safety. Doses at the lower end, like 10-15 ml, are usually below the label’s minimum and may not provide adequate control. Doses at 25-30 ml or 30-40 ml exceed the recommended range and can be wasteful, potentially unsafe for the crop, and may violate label restrictions. Always calibrate your sprayer to the labeled rate and adjust for spray volume and pest stage to optimize results.
