IMPORTANT 
Injury 10 Of loss of desirable Irees or vegetation may resuh 
from failure to observe the following: Do not apply or dnoin 
or nush equipment on or ncar desirable trees or other planls, 
or on arcas where their roots may extend, Of in local ions 
where the chemical may be washed Of moved illin conlact 
wilh their roots, Do nOI usc on lawns, walks, driveways, 
tennis couns, or similar areas. Prevent drift of spray 10 
desirable planls. Do nOI conlaminale any body (If waler. 
Keep from contact with fenilizcrs, insecticides, fungicides, 
and seeds during storage. 
Prior to using" Lorox Plus". consideration should be 
given to crop rotation plans, Crops other than soybeans 
can be extremely sensitive to low concentrations of "Lorox 
Plus" remaining in the soil the nexl planting season. Choice 
of rotational crop is restricted following application of 
''Lorox Plus". (See "ROTATIONAL CROP GUIDE­
LINES"). 
Do not apply if soil pH is greater than 6,S. 
''Lorox Plus" is registered for use on soybeans only. Use on 
crops other than soybeans will result in severe crop injury or 
crop death. 
GENERAL INFORMATION 
Du Pont ''Lorox Plus" Herbicide is a dispersible granule 
fonnulation to be mixed with water and sprayed for 
selective preemergence weed control in soybeans. When 
applied according to the instructions on this label, it will 
control many broad leaf weeds and provide panial control of 
nutsedge. 
Preemergence applications of ''LOrtlX Plus" require rainfall 
or sprinkler irrigation to activate the herbicide. Degree of 
control and duration of effect depend on: rate used, weed 
spectrum, growing condilions at and following time of 
treatment, soil pH, texture, organic malter, moislure and 
precipitation. 
Because most crops arc highly sensitive to "Lorox Plus", all 
direct or indirect contact (such as spray drift) to crops or 10 
land scheduled to be planted to crops other than soybeans 
should be avoided. 
BIOLOGICAL ACTIVI7'Y 
''Lorox Plus" rapidly inhibits the growth of susceptible 
weeds. Following preemergc nce treatment, susceptible 
weeds may genninate and ernerge, but growth then ceases 
and leaves become yellow 3 .. 5 days aftel emergence. Death 
of leaf tissue and growing point will follow in some species 
while others will remain green but stunltd and noncompeti­
tive. "Lorox Plus" provides panial control of some annual 
grasses, but olher products may be needed 10 ensure 
adequate grass conlrol.

AGRICULTURAL USE REQUIREMENTS 
Usc this product only in accordance with its labeling and 
wilh the Worker Protection Standard, 40 CFR part 170. 
This Standard contains rc4uiremenls for Ihe prolection of 
agricultural workers ('0 farms. forests, nurseries, and 
greenhouses, and handlers of agricultural pesticides. It 
contains requirements for training, deconlamination, nOli­
fication, and emergency assislance. It also conlains 
speCific instructions and exceptions penaining to the 
statements on this label about personal protective 
equipment(PPE) and restricted-entry interval. The 
requirements in this box only apply to uses of this 
product that are covered by the Worker Protection 
Standard. 
Do not enter or allow worker entry into treated areas 
during the restricted entry interval (REI) of 12 hours. 
PPE required for early entry to treated areas that is 
pennitted under the Worker Protection Standard and that 
involves contact with anything that has been treated, such 
as plants, soil, or water, is: 
• Coveralls over shon-sleeved shin and shon pants. 
• Waterproof gloves. 
• Chemical-resistant footwear plus socks. 
• Protective eyewear. 
• Chemical-resistant headgear for overhead exposure. 
Do not apply this product through any type of irrigation 
system. 
EQu/PMENT-SPRA Y VOLUMES 
Apply uniformly by ground equipment with a properly cali­
brated low pressure (20 to 40 psi) fixed-boom sprayer 
equipped with fan-type nozzles or olher carefully calibraled 
nozzles and screens no finer than 50 mesh. Usc 10 10 40 
gals of water per acre. 
Continuous agitation in the spray tank is required to keel) 
the material in suspension. Avoid overlap and shut off s )ray 
booms while slaning, luming, slowing or stopping, as injury 
to the crop may result. 
EARLY PREPLANT OR PREPLANT

PREEMERGENCE USE ON SOYBEANS 
(See Rate Chart) 
Apply before soybeans emerge. Do nol spray over 101' of 
emerged soybeans or severe crop injury or crop death will occur. 
"reemergence aClivily of "Lorox Plus" requires rainfall or irriga­
lion 10 activale. Besl resulls are obIainc'll if Irealmenl is made 10 
moist soil and followed by rainfall or irrigalion ( 1/2" 10 I") 
before weeds germinale. On dry soil, chemical aClivalion 
requires more moislure (1-2"). If moisture is insufflCienilo 
aelivale the herbicide, a rotary hoeing or shallow cullivalion 
should be made after emergence of crop while weeds are small 
enough to be controlled by mechanical means. ''Lorox Plus" can 
be applied prcemcrgence in combinalion with "Lasso", "Dual", 
"ProwI"[3], "Surflan'14] or following the use of a preplan! grass 
material such as ''freflan'' ''Prowl'' or "Sanalan". Consult labels 
for raY_s and use instructions. 
SOYJ3EANS - MINIMUM TILLAGE OR NO-TILL 
(See Rate Chart) 
''Lorox Plus" appliea ::>reemergence to soybeans but poslemer­
gence to broodleaf wC';ds and small annual grasses will provide 
limited bumdown of existing weeds. When used for burndown 
add 0.25% VN surfactant I) qtllOO gal) such as Surfactant WK 
or crop oil concent.te at 0.25% V/V (I qtllOO gal). For added 
burndown of broodleaf weeds, ''Lorox Plus" may be tank mixed 
with 2,4-D low volatile ester. Do not apply 2,4-D ester within 30 
days of planting. For added postemergence control, especially on 
grasses, ''!..orox Plus" can be applied with ''Roundup''[ I], 
paraquat or "Bronco"[ I]. For added preemergence control, espe­
cially on grasses, ''Lorox Plu.;" can be mixed with ''Oual'', 
''Lasso'', or "Surflan". Consult labels for rates and usc instruc­
tions. Maintain constant agitation of spray mixture.

When tank mixing with other herbicides, all applicable direc­
tions, restrictions and precautions for the additional herbicides 
arc also to be followed. Use "Lorox Plus" spray preparations 
the same day as mixed or product degradation may occur. 
Thoroughly reagitate before using if allowed to settle. 
ROTATIONAL CROP GUIDELINES 
Crops thai can be planted after using "Lorox Plus" are listed 
below. Choice of rotational crop is detemlined by time 
interval elapsed since last application. Prior to 18 months 
following application, do not rotate crops used for food or 
feed, which arc not registered for usc wilh "Lorox Plus" or Du 
Pont "Lorox" Herbicide onto areas previously trealed with 
these chemicals.

CAUTION: Soil pH varies greatly even wilhin the same 
field. pH varialions as much as 2 pH units are common 
when the soil has a calcareous sub soil. Detemline soil pH 
by laboratory analysis using a I: I soil:water suspension. 
Do not graze treated fields or harvest for forage or hay. 
Use of "Lorox Plus" may affect rotational crops. Follow 
"ROTATIONAL CROP GUIDELINES. 
Do not use on sand, muck, or peat soils, nor on soils with 
less than 1/2% organic matter, as crop injury may occur. 
Do not apply ''Lorox Plus" after the soybean crop has 
emerged. 
If "Scepter"(3), "Pursuil"(3] or any product containing the 
active ingredients, imazaquin or imazethapyr (such as 
"Squadron"[3], ''Partner''[3]) is applied the same year as 
''Lowx Plus", do not plant crops other than soybeans for at 
least 15 months from Ihe laSI application. Crops listed in Ihe 
"'Lorox Plus' Rotational Crop Guidelines" may be planted 
after 15 months; all other crops require a successful field 
bioassay. 
Do not apply to land that has ':leen or will be treated with 
"Glean l\ IIAlly" or l'Finesse
