What is the recommended dosage for cucumber beetles on cucumbers?

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

Answer: (D)

Effective control of cucumber beetles on cucumbers hinges on following the product label for rate, coverage, and timing. The label sets the amount to apply per area and the amount of water or spray volume needed to ensure the pests are exposed and killed. When beetle pressure is high or foliage is dense, using the upper end of the label’s rate is usually necessary to achieve thorough spray coverage across the canopy and to reduce feeding damage. Lower rates tend to provide insufficient pest kill, leaving beetles alive to continue feeding and potentially leading to reduced long-term effectiveness. Therefore, the best choice is the highest rate listed on the label. Always follow the label directions for the exact application rate, spray volume, pre-harvest interval, and safety precautions, and ensure the product is registered for cucumbers in Alberta.
