Stark™ Ultra provides selective post-emergence control of tough annual and perennial broadleaf weeds that rob crops from vital nutrients, preventing them from reaching their full yield potential.
Stark Ultra features the active ingredient fluroxypyr, a growth regulator herbicide that disrupts targeted weeds causing abnormal growth and starving it of vital nutrients. Stark Ultra has been proven effective on ALS resistant kochia making it an excellent go-to herbicide.
Stark Ultra is absorbed by leaves and shoots of emerged weeds and is rainfast in as little as one hour. Stark Ultra is an excellent tank-mix partner and offers a flexible application window with outstanding crop safety.
