In-Crop Herbicide Selection and Timing

Posted: May 31, 2016

How to stage your sunflowers for spray timing?

The minimum plant stage for most herbicides in sunflower is 2-leaf. These are the first two leaves that come out opposite of the cotyledons. The next leaves must be half as long as the previous ones to be considered 3-4 leaf. The same rule applies up to the 8-leaf stage.

*Reminder to consult your Guide to Crop Protection for further information.
