RE-ENTRY STATEMENT (FOR USE IN S\~EET CORN IF HAND LABOR IS INVOLVED) 
Do not enter treated areas without protective clothing until sprays have dried. 
Protective cl~thing means, at least, a hat or other suitable head cov~ring, a 
long-sleeved shirt and long-legged trousers or a coverall-type garment (all of 
closely woven fabric covering the body, including the arms and legs), imper­
meable gloves and boots. Because certain states may require more restrictive 
re-entry intervals for various crops treated with this product, consult your 
State Department of Agriculture for further information. 
Written or oral warnings must be given to workers who aLe expected to be in a 
treated area or in an area about to be treated with this product. When oral 
warnings are given, warnings shall be given in a language customarily understood 
by workers. Oral warnings must be given if there is reason to believe that 
written warnings cannot be understood by workers. Written warnings must include 
the following information: "CAUTION. Area treated with PROZINE on (date of 
application). Do not enter without appropriate protective clothing." 
GENERAL INFORMATION 
PROZINE controls many annual broad leaf and grass weeds in corn and sorghum. It 
may be applied b~fore or after weeds el.~rge. The effectivenes9 of this product 
depends on moistut~ to move it into the root zone. If weeds develop, a shallow 
cultivat~on or rotary hoeing will generally result in better weed control. 
Unusually cold, excessively wet, or hot and dry conditions that delay ger­
mination or extend germination over a long period of time can reduce weed 
control •. 
Seedling diseases, cold weather, excessive moisture, deep planting, low or high 
soil pH, high soil salt concentration, or drought can weaken seedlings and 
plants and increase the possibility of crop damage from this herbicide. Under 
these conditions, crop yields can be reduced. 
A;plication in Water or Liquid Fertilizer: Nitrogen solution or complete liquid 
fertilizer may replace all or part of the water as a carrier for preemergence on 
corn. Check the compatibility of this product with liquid fertilizer and/or 
nitrogen solution as shown below before use. Do not apply in nitrogen solution • • or complete liquid fertilizer after corn emerges. : ••••• 
• ••••• •••• • • • • • • • •••• • ••••• • • • •• • • •••••• ••••• • • • ••••• •••• • • • • •• • ••••••• • • • •• •• • • • • •••••• •• • • • •• •• •••• • • • •• •

To determine the compatibility of PROZINE with liquid fertilizer, pour the pro­
duct into a small container of liquid fertilizer in the proportions shown below. 
For diffr -:"cnt spray volume or herbicide rate) make appropriate changes in the 
ingredients. 
For each pound of PROZINE to be applied per acre, add I level tea£~oon of the 
product to one pint of liquid fertilizer (assuming a volume of 25 gallons per 
ac re). 
After thorough mixing, let stand 5 minutes. If the 1lerbicide/fertilizer com­
bination remains mixed, or can be remixed readily, make a slurry with the her­
bicide before adding fertilizer and use the mixture only if this test shows it 
is compatible. 
ROT,\TIONAL CROPS: (1) Do not rotate to any crop except COrn or sorghum until 
the following year, as injury may occur. (2) In the High Plains and intermoun­
tain areas of the West where rainfall is sparse and erratic or where irrigation 
is r~quired, use only when corn or sorghum is to folloy corn or sorghum or when 
a crop of. untreated coru or sorghum is to precede other rotational crops. (3) 
Injury may occur to soybeans planted in north-central and northwest Iowa, south­
central and southwest Minnesota, northeast Nebraska, southeast South Dakota, and 
other areas the year following application on soils having a calcareous surface 
layer •. (4) Do not plant sugarbeets, tobacco, vegetables (including dry beans), 
spring-seeded small grains, or small-seeded legumes and grasses the year 
following application as injury may occur. 
APPLICATION PROCEDURES 
GROUND APPLICAITON: Use conventional ground sprayers ~quipped with nozzles that 
provide accurate and uniform application. Be certain that nozzles are uniformly 
spaced and are the same size. Calibrate sprayer before use and recalibrate at 
the start of each season and when changing carriers. Unless otherwise spec­
ified, use a minimum of 10 gallons of spray mixture per acre for preemergence 
and postemergence applications with ground equipment. 
Use a pump with capacity to (1) maintain 35-40 psi at nozzles, (2) provide 
sufficient agitation in tank to keep mixture in suspension, and (3) to provide a 
minimum of 20% bypass at all times. Use centrifugal pumps which provide pro­
peller shear action for dispersing and mixing this product. The pump should 
provide a miniQum of 10 gallons per minute per 100 gallons tank size circulated 
through a correctly positioned sparger tube or jets. : ••• :~

UiXING PROCEDURbS - ALL USES: Be sure sprayer is ctean and not cor-taminated 
with any other materials, or crop injury or sprayer clogging may result. Fill 
tank! full with clean water, nitrogell solution, or complete liquid fertilizer. 
Start agitation. Be certain that the agitation system is working properly and 
creates a rippling or rolling action on the liquid surface. Pour product 
directly from cQntaincr into tank. Let it wet and settle into solution. 
Continue filling tank until 90% full. Increase agitation if necessary to main­
tain surface action. Finist filling tank. Haintain agi.tation to avoid separa­
tion of materials. Clean sprayer thoroughly immediately after use by flushing 
system with water containing a detergent.

CORN - FIELD AND S~lEET 
GENERAL U:STRUCTlONS 
Us~ only whe~e adequate tillage is practiced to provide good soil coverage of 
the corn seed. Plant corn AT LEAST I! inches deep to ensure good seed coverage. 
PROZINE is most effective in controlling weeds when adequate rainfall or 
overhead irrigation is received within I days after application. If cultivation 
is ne~essary because of soil crusting, soil compaction or weed germination 
before rain or irrigation) use shallow tillage (such as rotary hoe), and make 
certain corn seeds are below the tilled area. For maximum effectiveness, wait 
at least 7 to 10 days before cultivating early postemergence treatments. 
Field Corn Grown In Minimum Tillage Systems 
PROZINE may be used in field corn in minimum tillage systems where adequ'lte 
tillage is practiced to provide a seedbed without living vegetation and which 
allows for good seed coverage. Plant corn AT LEAST H inches deep to ensure 
good s~ed coverage. The use of no-till planters in minimum tillage corn under 
conditions which do not allow good soil coverage of the corn seed can result in 
reduced crop stand or injury if PROZINE contacts the germinating corn seed. 
Check equipment to enSure good seed coverage. Apply in 20 or more gallons of 
spray sol~ion per acre. 
PREEMERGENCE (Surface Treatment After Planting) 
Apply PROZINE preemergence after planting, but before weeds or crop emerge. 
Apply in water or liquid fertilizer with ground equipment or in water with 
aircraft. Refer to section on application in water or liquid fertilizer for 
liquid fertilizer compatibility determinations. DO NOT INCORPORATE or serious 
corn injury will ~esult. 
EARLY POSTEMERGENCE 
Apply PROZINE after corn 
stage of growth and when

NOTE FOR ALL APPLICATI~NS TO ·~ORN: DO NOT graze or feed forage from treated 
areas for 21 days following application. 
FIELD CORN AND GRAIN SORGllUH 
POSTEHERGENCE INCORPORATED APPLICATIONS 
GENERAL INFORMATION: Winter wheat and winter barley may be planted in the fall 
90 days after an application with PROZINE postemergence incorporated in irri­
gated field corn or grain sorghum or 120 days after an application in dry land 
field corn or grain sorghum. The treated crop must be grown to maturity and 
harvested before planting wheat or barley. See GENERAL INFORMATION for complete 
~otational instructions. 
PROZINE applied as a postemergence incorporated treatment will control most late 
seas~n annual grasses and certain broad leaf weeds in field corn or grain 
sorghum. Treat~ents can be applied from the 4-inch growth stage to as late as 
the last cultivation (layby) of field corn or grain sorghum. Treatments will 
not control established weeds. EMERGED WEEDS ~ruST BE DESTROYED BY CULTIVATION 
PRIOR TO APPLICATION.

Treatments must be thoroughly and uniformly incorporated into th~ soil (1) with 
a sweep-type or rolling cultivator set to provide thorough ilh.:orporation in the 
top 1 inch cf soil or (2) with adequate irrigation water or rainfall. For best 
results, treatments should be incorporated as soon as possible after application 
but incorporaticn must be completed within 7 days after application. If ade­
quate moisture is not ~~ceived within 7 days after application, PROZINE must be 
incorporated with a sweep-type or rolling cultivator. 
Under situations of l~w rainfall or soil moisture, when deep germinating weeds 
~uch as shattercane ur field sandbur are anticipated, mechanical incorporation 
will provide best results. 
If cultivation i~ ~eede~ ~fcer appli~ation and incorporation, the depth of cut 
should be no deeper than the depth of "~ ~seq co incorporate. 
DO NOT APPLY PROZINE in field corn or grain sorghum mOre than once per crop 
season. 
WEEDS CONTROLLED: When applied as directed, PROZINE will control shattercane 
(sorghum bicolor) and wild proso millet (panicum miliaceum) in addition to the 
WEED SPECIES CONTROLLED previously listed. 
ADDITIONAL HERBICIDE APPLICATIONS: Postemergence incorporated applications of 
PROZINE can be applied in field corn or grain sorghum previously treated with 
herbicides registered for use in field corn or grain sorghum. Consult the 
labels of those herbicides for suggested treatments, rates to bp. used, and pre­
cautions or restrictions for use in field corn or grain sorghum and for restric­
tions on following crops.
