Keep from contact with feniliurs, insecticides, fungicides, 
and seeds during storage. 
PRIOR TO USING "GEMINl", CONSIDERA nON 
SHOULD BE GIVEN TO CROP ROTAnON PLANS. 
Crops other than soybeans can be extremely sensitive to low 
concentrations of ''Gemini'' remaining in the soil the next 
planting season. Choice of rotational crop is restricted 
following application of ''Gemini''. (See "ROTA nONAL 
CROP GUIDELINES".) 
Thoroughly clean all traces of ''Gemini'' from application 
equipment immediately after use and prior to spraying crops 
other than soybeans. Failure to remove even small amounts

FOR USE ON SOYBEANS ONLY, 
GENERAL INFORMATION 
Du Pont ''Gemini'' Herbicide is a dispersible granule formula­
tion to be mixed with water and sprayed for selective preemer· 
gence weed control in soybeans. When applied according to the 
insbUctions on this label, it will control many broadleaf weeds 
and provide partial control of nutsedge and annual grasses. 
Preemergence and JlRpllIltlnalrponted applications of 
''Gemini'' require rainfall or sprinkler irrigation to activate the 
herbicide. Degree of control and duration of effect depend on: 
rate used, weed SpeCbUm, growing conditions at and following 
time of treatment, soil pH, texture, organic matter, moisture, 
and precipitation. 
Because most crops are highly sensitive to ''Gemini'', all direct 
or indirect contact (such as spray drift) to crllpS or to land 
scheduled to be planted to crops other than soybeans should be 
avoided. 
BIOLOGICAL ACTIVITY 
''Gemini'' rapidly inhibits the growth of susceptible weeds. 
Following activation of preplant incorporated or preemergence 
treatment, susceptible weeds may germinate and emerge, but 
growth then ceases and leaves become yellow 3-5 days after 
emergence. Death ofleaf tissue ~nd growing point will follow 
in some species while others remain green but stunted and 
noncompetitive. ''Gemini'' provides partial control of some 
annual grasses when used Preplant or preemergence but other 
products may be needed to ensure adequate grass control. 
WEEDS CONTROLLED 
When used as directed ''Gemini'' will provide conuol of the 
following weeds:

3. Thoroughly rinse sprayer, tanks, boo"" and hoses wi!h 
clean waler. 
4. Follow label direclions of \he product previously sprayed 
for rinsale disposal. 
NOTE: During an extended period where spraying or 
mixing equipment will be used to apply mulliple loads of 
"Gemini", al !he end of ~3ch day of spraying partially fill 
!he tank wi!h fresh waler, flush !he boom and hoses and 
allow to sil overnighl. 
EQUIPMENT / SPRA Y VOLUMES 
Apply uniformly by ground equipment wi!h a properly cali­
brated low pressure (20 to 40 psi) fixed·boom sprayer 
equipped wi!h fan·type nozzles and screens no finer !han 50 
mesh. Use 1010 40 gals. of water per acre. 
Conlinuous agitation in !he spray tank is required to keep 
\he malerial in suspension. Avoid overlap, and shul off 
spray booms while starting, turning, s,owing or stopping, or 
injury to Ihe crop may result. 
MIXING INSTRUCTIONS 
Fill tank 114 full wi!h water. Start agitation system, add 
''Gemini'' and continue adding water. Add sepll1ltely each 
additional componenl of any tank mix while adding waler. 
Continue agitation !hroughoul. If poor mixing should occur 
wi!h any componenl, premix Ihe componenl wi!h IWO parts 
water before adding to the spray tank. 
A fenilizer solulion may be used in !he spray mixture. Small 
quanti lies should be tesled for compalibilily by \he 
following procedures before full scale mixing. 
I. Pul I pinl of fenilizer solulion in a quan jar. 
2. Mix 2 leaspoons "Gemini" with 2 lablespoons of walcr; 
mix lhoroughly and add to fenilizer solulion. 
3. Close jar and shake well. 
4.lf olhcr herbicides arc to be used in the mixture, premix 2 
teaspoons of wenable powder or I leaspoon of liquid wi!h 
2 tablespoons of waler; add 10 ''Gemini''/fenilizer 
~olulion mixture. 
5. Close jar and sh~e well. 
6. Walch mixture for several seconds; check again in 30 
minutes. 
7. If mixture does nOI separal~, foam, gel, or become lumpy, 
it may be used. 
8. Mixing ability may be improved by adding compatibilily 
agents such as Kalo Laboralories' Compex' or Witco 
Chemicals' Spontct I68D. Follow directions on conlainer. 
Provided \he above procedure shows the mixture 10 be 
compatible, prepare Ihe tank mixture as follows: Add Ihe 
fertilizer solution to Ihe spray tank first. wi!h \he agitalor 
running, add !he required amount of ''Gemini'' and Ibor­
oughly mix. For tank mixtures wi!h olher herbicides, follow 
directions above. 
When tank mixing wi!h other herbicides, all applicable 
directions, restrictions and precautions for the additional 
herbicides are also to be followed. Use ''Gemini'' spray 
preparations the same day as mixed or product degradation 
may occur. Thoroughly reagitate before using if allowed 10 
sellle. 
APPLICATION METHODS 
If initial seeding fails to produce a stand, treated fields may 
be replanled to soybeans. Do not rework soil; do nOl retreal 
field wi!h a second application as injury to !he crop may 
result. Do not replanl treated areas to any crop o!her !han 
soybeans wi!hin four mon!hs after treatment as injury to 
subsequent crops may result. 
EARLY PREPLANT OR PREPLANT 
INCORPORATED (SEE RATE CHART) 
''Gemini'' may be applied at planting or up to 30 days prior 
to planting either pre. mergence or preplant incorporated. If 
incorporated, ''Gemini'' should be uniformly incorporaled 
no deeper !han \he top 1-2" of soil prior to planting 
soybeans. Use equipment suited for proper incorporalion 
into !he top 1-2 inches of soil e.g.: Oo-all, rleld cullivalor, 
Roterra. If tank-mixed wi!h a grass herbicide, such as a 
DNA like '7reflan", ''Sonalan'', or acetanilide such as 
''Dual'', or ''l...asso'', follow label instructions for proper 
incorporation of the grass herbicide into the top I to 2" of 
soil. Improper soil incorporation can result in erratic weed 
control or crop injury. Rainfall· (-I'') is required to activate 
preplant incorporaled herbicides such as ''Gemini'' before 
weed emergence. 
Use of a disk for incorporation is not recommended. 
''Gemini'' + '7reflan", ''Prowl'', ''Dual'' or Sonalan" - Apply 
within 2 weeks of planting. ''Gemini'' + ''Lasso'' - Apply 
wi!hin 7 days of planting. 
PREEMERGENCE (SEE RATE CHART) 
Preemergence application: Apply before soybeans emerge. 
Do not spray over lOp of emerged soybeans as severe injury 
or death of crop will occur. 
Preemergence activity of ''Gemini'' requires rainfall· to 
activale. Besl resulls are obtained if treatment is made 10 
mOiSI soil and followed by rainfall or irrigation (-I") before 
weeds germinate. On dry soil more moisture is required for 
BEST AVAILABLE COpy

activation (Ito 2") before'. weed emergence. If moisture is 
insuffidentto activate the herbicide. a rotary hoeing or 
shallow cultivation should be made after emergence of crop 
while weeds are small enough to be controlled by mechan­
ical means. ''Gemini'' can be apphed preemergence in 
combinalion with "Lasso". ''DuaJ". "Prow)'" "Suman''. or 
following the use of a preplan! grass material such as 
'"frenan" or "Sonalan." Consult labels for rates and use 
instructions. 
·Rainfall required to activate ppi or pre treatments depends 
on soil moisture when activating moisture is received. 
Several small rainfalls of less than 114" are not as benefICial 
as one large rain of 112 inch or more for activation. 
MINIMUM TILLAGE OR NO-TILL 
(SEE RATE CHART) 
''Gemini'' applied preernergence to soybeans but postemer­
genc~ to broadleaf weeds and small annual grasses will 
provide some burndown of existing weeds as well as normal 
preemergence broad leaf control. When used for burndown 
add 0.25% (I qIJlOO gal) surfactant such as ''Surfactant 
WK" or crop oil concentrate at 1% v/v (I gaVIOO gal). For 
added postem~rgence control especially on grasses. 
''Gemini'' can be applied with Roundup'. paraquat. or 
Bronco' _ For added preemergence gr3SS control ''Gemini'' 
can be mixed with ''Dual''. "Suman" or ''Lasso.'' Consult 
labels for rates and use in~ttuctions. Maintain constant 
agitation of spray mixture. 
RATE CHART 
Apply as follows: 
Soil Texture Rate 
(1/2 - 3% Organic Maller) (Ounces Per Acre) 
Coarse: 
Loamy sand 12-16 
Medium: 
Loam. Silty loam. Silt 16-20 
Fine:

Do not use on sand or loamy sand nor on any soil with 
less than 112 percent organic maller_ 
Do not apply ''Gemini'' on soils with pH greater than 7.0 
except in those states as directed in the ''ROTATIONAL 
CROP GUIDELINES" where application can be made to 
soils with a pH up to 7.5_ 
REDUCED RATE FOLLOWED BY 
"CLASSIC" HERBICIDE 
"Gemini" Herbicide is recommended preplant incorporated 
or preernergence at reduced rates followed by "Classic" 
Herbicide postemergence for broadleaf weed control in 
soybeans. This trcatmellt will control those broadleaf weeds 
listed on the "Gemini" and "Ciassic" Herbicide product 
labels. 
Apply "Gemini" preplan! incorporated or preemergence at 
8-10 ounces product per acre to any soil texture with 1/2to 
3% organic mailer as directed 011 the product label. Follow 
the "Gemini" preplant incorporated or preemergence 
reduced rate with a postemergence application of "Classic" 
~; (,1 
Herbicide at its labeled rate when weeds are small and 
actively growing. (Usually 14-28 days after pre plant incor­
porated or preemergence application of "Gemini" reduced 
rate.) 
For grass weed control "Gemini" can be tank mixed with 
Dual, Lasso. Sonalan. Trenan or Suman. Consult labels for 
rates and use instructions of these products. 
Dosage rates listed are for broadcast rates. For band applica­
tions use proponionately less. 
Plant seed I 112 to 2" deep on a nat or raised seedbed only, 
or crop injury may oecur. 
Soybean stunting may oecur if excessive rainfall occurs 
after application. Injury is more prevalent under poor 
drainage or compacted conditions or when soil is satur3ted 
for long periods of time. Soybeans rapidly outgrow stunting 
once favorable growing conditions return. 
Injury to soybeans may occur if "Gemini" is used on soils 
having a calcareous surfllCC layer or a pH of 7_0 or higher. 
or if used in conjunction with soil-applied insecticides. 
Seedling disease. cold or hot weather. deep planting (more 
than 2''). excessive moisture. high salt concentration. 0;­
drought may weaken soybean seedlings :md increase possi­
bility of crop injury. Do not apply to Black Belt Soils of 
Alabama and Mississippi with a soil pH greater than 7.0 or 
a history of nutrient defICiency such as iron chlorosis. as 
injury may oecur_

PRECAUTIONS 
Do not apply ''Gemini''lo soils with a pH greater than 7.0. 
e"cept for those Slates listed in Group 11\ of the ''ROTA­
TIONAL CROP GUIDELINES" where ''Gemini'' can be 
applied to soils up 10 7..s pH. 
o CAunON: Soil pH varies greatly. even within the same 
field. pH variations as much as 2 pH units an: common. 
Composite soil samples taken across an entin: field. such 
as those samples taken for soil fettility n:commendations. 
may not detect areas of high pH (gn:ater than pH 6.8). 
Sub-sampling areas likely to have pH values higher than 
the field average is recommended. 
Soil pH may vary with soil rype. When: different soil 
tyres an: evident within a fteld. these types should be 
sampled separately_ 
Soil pH may vary due to conditions within a field. Such 
areas include. but an: not limited to. areas bordered by 
limestone gravel roads. river bonoms subject to flooding. 
low an:as in hardpan soils where evaporative ponds may 
occur. eroded hillsides. along drain tile lines. and areas 
where drainage ditch spoil has been spread. These areas 
should be sampled separately. 
Soil pH may vary within the soil profile. For instance. 
fields in which lime has not been deeply incorporaled
