Sunflower Pests

In all cases, follow the instructions on the pesticide label. The PNW Insect Management Handbook has no legal status, whereas the pesticide label is a legal document. Read the product label before making any pesticide applications.

Note: Products are listed in alphabetical order and not in order of preference or superiority of pest control.

Hybrid sunflowers are largely self-pollinating, but insect activity can increase seed yield. Most insecticides labeled for sunflowers are highly toxic to bees, so pest management programs should be conducted to prevent bee mortality. Spray applications should be restricted to very early morning or, preferably, late evening. Insecticides should not be applied to sunflowers in bloom until area beekeepers have been allowed to remove bee hives from the area.
