to 8 inch tall sweet com) application in sweet com. A single or split application may be used. 
Before application to sweet com, verify with your local seed company (supplier) the selectivity of 
FRONTI ER on your specific variety(s). This precaution will help avoid potential injury to sensitive varieties. 
Delayed emergence or leaf wrapping of sweet com may occur if extreme conditions of high rainfall with 
extended periods of water saturated soil and/or cool weather occur during sweet com germination and emergence. - ~ coo -- -.~ 0 ~ --~ ~ ~-- _-~~o_

FRONTIER TANK MIXTURES AND SEQUENTIAL USE PROGRAMS IN SWEET CORN 
Tank mixtures and sequential use programs for field com, seed com, and popcom in Directions for Use 
Booklet attached to the FRONTIER container label apply for use in sweet com when the companion product 
is registered for sweet com use. Always read the companion product label(s) to verify allowed uses in 
sweet com including: specific use rates by soil types, weed species, and weed or crop growth stage. 
Follow all precautions and restrictions including state and local use restrictions that may apply to specific 
companion products. In addition this product can be used prior to or tank mixed with Basagran® or 
Laddok® S-12 herbicides for use on sweet com in accordance with the most restrictive of label limitations 
and precautions. No label dosage rates should be exceeded. This product cannot be mixed with any 
product containing a label prohibition against such mixing. 
FRONTIER GRAIN SORGHUM USE PROGRAMS 
FRONTIER may be used as a preplant surface, preplant incorporated, or preemergence application in 
sorghum. A single or split application program may be used. All FRONTIER applications must only be made 
to sorghum seed that has been properly treated by the seed company with an approved chloroacetamide 
herbicide safener or severe injury may occur. 
Under high soil moisture and/or cool conditions, FRONTIER application may cause temporary stunting or leaf 
wrapping of sorghum. Sorghum will normally outgrow these symptoms in 10-14 days. 
For best performance make preemergence surface applications within 5 days of the last preplant tillage. If 
weeds are emerged apply FRONTIER with contact herbicides to control emerged vegetation. 
Sorghum forage may be grazed or fed to livestock at 60 or more days after application. Grain and fodder 
may be harvested and fed at 80 or more days after application of FRONTIER. 
FRONTIER is not registered for use on sweet or forage sorghum. 
FRONTIER USE RATES IN SORGHUM 
For FRONTIER rates in sorghum use rates given for field com, seed com and popcom in the Directions for 
Use Booklet attached to the FRONTIER container. Additional rate recommendations specific for sorghum: 
for best weed control in coarse textured soil use 16 fl ozlA and for sorghum produced under irrigation, use 
a minimum of 18 f1 ozlA.
