GENERAL INFORMATION
Expert is a herbicide that may be applied before or after weed emergence for control of many annual grass and broadleaf weeds in corn. This product will also provide in-season control of certain emerged perennial weeds. Expert may be applied up to 30 days before, during, or after planting all types of corn grown under no-tillage or other reduced tillage practices, but prior to emergence of corn that is not specifically designated as Roundup Ready. Expert can also be used before crop emergence for control of many annual grass and broadleaf weeds in grain or forage sorghum, provided the sorghum seed has been properly treated by the seed company with Concep III. This product may be tank mixed with other herbicides specified on this label for weed control in conventional, minimum-till, and no-till corn, grain sorghum, or forage sorghum.
USE PRECAUTIONS: DO NOT APPLY EXPERT AFTER SORGHUM EMERGES. DO NOT APPLY EXPERT AFTER CORN EMERGES UNLESS THE CORN SEED IS SPECIFICALLY DESIGNATED AS ROUNDUP READY. FAILURE TO COMPLY WITH THIS USE PRECAUTION WILL CAUSE SEVERE INJURY OR DEATH TO NONROUNDUP READY CORN AND SORGHUM PLANTS.
Note: Tank mixtures are permitted only in those states and crops and where the tank mix partner is registered. Follow the label of each product used for precautionary statements, directions for use, geographic and other restrictions.
When tank mixing or sequentially applying atrazine or products containing atrazine to corn or sorghum, the total pounds of atrazine applied (lb ai per acre) must not exceed 2.5 pounds active ingredient per acre.
Before corn or sorghum emerges, water or fluid fertilizer (28%-32% nitrogen solutions only) may be used as the carrier when applying Expert alone or in tank mixtures approved on this label. Control of emerged weeds, especially perennial species, may be reduced if fluid fertilizer is used as the carrier. Do not use complex fluid fertilizers such as 10-34-0 as the spray carrier when applying Expert. Expert may be applied to Roundup Ready corn after emergence up to a corn height of 12 inches tall. Use only water as a carrier when applying Expert after Roundup Ready corn emergence. Do not apply Expert in tank mixture with any other products after crop emergence.
Where reference is made to weeds partially controlled, partial control means significant activity, but not always at a level generally considered acceptable for commercial weed control.
Use Precautions: (1) If sorghum seed is not properly pretreated with Concep, Expert may severely injure the crop. (2) Injury may occur to sorghum following the use of Expert under abnormally high soil moisture conditions during early development of the crop.
Expert alone or in tank mixture with Dual II Magnum, AAtrex 4L or AAtrex Nine-O (atrazine), Princep 4L or Princep Caliber 90 (simazine), Touchdown or Roundup (glyphosate), Python, Hornet, Prowl (pendimethalin), Banvel or Clarity (dicamba), or 2,4-D may be applied to corn preplant or preemergence, in water or fluid fertilizer.
Expert alone or in combination with Touchdown or Roundup (glyphosate) may be applied to sorghum preplant or preemergence in water or fluid fertilizer, provided the sorghum seed has been properly treated by the seed company with Concep III.
Triazine resistant biotypes of some weeds have developed following many years of continuous use of atrazine (one of the ingredients in Expert) and other triazines. For best results, where triazine resistant biotypes are known or suspected to exist with other weeds, Syngenta recommends the use of Expert after emergence of resistant biotypes. Consult with your State Agricultural Extension Service for specific recommendations.
