What is the recommended dosage to control alfalfa looper?

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

Answer: (A)

The essential idea here is that pesticide dosing is governed by the product label, which tells you the exact amount to mix for effective control. For alfalfa looper, the label for the commonly used insecticide specifies a recommended rate of 15–20 ml of product per liter of spray solution. This range is set to achieve good pest kill while keeping within safety, environmental, and crop-t safety margins and avoiding unnecessary waste. A rate as low as 5 ml would likely underdose the spray, leading to poor control. Rates much higher than the labeled range, like 50 ml or 100 ml, can exceed label limits, increase the risk of phytotoxicity or residues, and waste money. Always mix to the labeled rate and calibrate your sprayer to apply that amount evenly over the target area.
