• Buctril/Moxy (bromoxynil) is a contact herbicide that controls many annual broadleaf weeds, including black nightshade, cocklebur, ragweeds, lambsquarters, and smartweed, but is weak on pigweed and large velvetleaf.
• Mode of action: photosynthesis inhibitor.
• Buctril/moxy may be applied at a rate of 1 pint per acre from corn emergence until tassel emergence. The 1 1/2-pint rate may be applied after corn reaches the 4-leaf stage and before tassel emergence. Maximum corn size at the time of application varies with the tank-mix partner.
• Do not apply to seed corn inbreds or popcorn prior to the 3-leaf stage.
• Do not use surfactant or crop oil when applying Buctril/Moxy alone or with most other herbicides. Nonionic surfactant and fertilizer solution are allowed in some tank mixtures.
• Apply in a minimum volume of 10 gpa at a minimum pressure of 30 psi using flat fan nozzles.
• May cause corn leaf burn, but effects are usually temporary.
