Weed control
When planted in wide rows, sunflower can be easily cultivated for weed control.
Delaying planting to allow more time for shallow tillage can aid in control of some early
season weeds. Most sunflower varieties grow rapidly and can compete effectively with
weeds once they are well established (this is less true for dwarf sunflower).
Several herbicides are registered for sunflower, including compounds such as Eptam,
Treflan, Sonalan, Poast, Assert and Prowl. Since the list of registered products changes
periodically, growers are encouraged to contact MU Extension personnel or industry
representatives for up-to-date information.
Insects
Both beneficial and pest insects can be found on sunflower plants in the summer,
especially around the head. Many insect pests are known to cause head damage, but the
damage usually is quite limited.
Insect pests that occasionally appear on sunflower plants include sunflower moth,
