Mode of Action 
Lightning® 0 herbicide kills weeds by root and/or foliar 
uptake and rapid translocation to the growing points. 
Adequate soil moisture is important for optimum 
Lightning 0 activity. When adequate soil moisture is 
present, Lightning 0 will provide residual control of suscep­
tible germinating weeds; activity on established weeds will 
depend on the weed species and the location of its root 
system in the soil. 
Herbicide Resistance 
Naturally occurring biotypes* of some of the weeds listed 
on this label may not be effectively controlled by this and/or 
other products with the ALS/AHAS enzyme-inhibiting 
mode of action. Other herbicide with the ALS/AHAS 
enzyme inhibiting mode of action include the the sulfony­
lureas (e.g. Accen~, Classi c4i>, Permi~, Steadfas~, 
Spir[t4l>, etc.) the sulfonamides (e.g. Python4i>, etc.), the 
pyrimidyl benzoates (e.g. Staple4i>, etc.), and the imidazoli­
nones (e.g. Pursui~, Scepter4l>, Raptor4l>, etc.). Herbicides 
with the growth regulating mode of action include the 
benzoic acid herbicides (e.g. Banvel4i>, Clarity4l>, Oistinc~, 
etc.), the phenoxyacid herbicides (e.g. 2,4-0, 2,4-DB, etc.) 
and the pyridine herbicides (e.g. Stingerz'). If naturally 
occurring biotypes are present in a field which are resistant 
to one of the herbicides in this premix and are not con­
trolled by the other mode of action herbicide in this premix, 
Lightning D should be tank mixed or applied sequentially 
with an appropriate registered herbicide having a different 
mode of action to ensure control. 
*A weed biotype is a naturally occurring individual within a 
given species that has a slightly different, but distinct 
genetic makeup from other plants. Lightning 0 is active 
against many broadleaf and grass weed species. For long 
term weed management, Lightning 0 contains three her­
bicides with two different modes of action to reduce the 
potential for selecting tolerant weeds (resistant weeds). 
Crop Tolerance 
Crops growing under stressful environmental conditions 
can exhibit various injury symptoms which may be more 
pronounced if herbicides are used. Corn plants treated 
with Lightning 0 may exhibit yellowing on new growth. 
Such effects occur infrequently and are temporary. Normal 
growth and appearance should resume within 1 to 2 
weeks. 
Use of Lightning 0 in accordance with label directions is 
expected to result in normal growth of rotational crops in 
most situations; however, various environmental and agro­
nomic factors make it impossible to eliminate all risks asso­
ciated with the use of this product and, therefore, rotational 
crop injury is always possible. Under some conditions 
(such as heavy texture soil, high organic matter, low pH or 
low rainfall), Lightning 0 may cause injury to subsequent 
planted crops. See the ROTATIONAL CROPS GUIDE­
LINE section of this label for recommended rotation inter­
vals to sensitive crops. 
() 
Soil Insecticide Information 
All soil insecticides, including labeled banded or infurrow 
applications, may be used in combination with Pionee~ 
i~idazolinone-resistant (IR) corn hybrids and Lightning O. 
BASF recommends that terbufos and phorate in banded 
applications may be used in combination with Lightning 0 
on imidazolinone-tolerant (11) corn hybrids. DO NOT use ter­
bufos when Lightning 0 will be applied to imidazolinone­
tolerant corn hybrids. BASF has not tested all hybrids in 
which the imidazolinone-tolerance trait is claimed and 
cannot be responsible for factors which are beyond its 
control, such as growing conditions, environmental condi­
tions, grower practices and the specific genetics of each 
hybrid tolerance to herbicide and insecticide applications. 
Cultivation 
For maximum weed control, cultivate 7-10 days following 
Lightning 0 application. This timely cultivation will 
enhance residual weed control, especially under dry 
conditions. 
Cleaning Spray Equipment 
To avoid injury to sensitive crops, drain and clean applica­
tion equipment thoroughly using a strong detergent or 
commercial sprayer cleaner according to the manufac­
turer's directions and then triple rinse the equipment before 
and after applying Lightning O. 
Application Instructions 
Lightning 0 is effective in controlling annual weeds in con­
servation tillage as well as in conventional production 
systems. Apply Lightning 0 as a postemergence treat­
ment to CLEARFIEL04i> corn when crop and weeds are 
actively growing. For optimal weed control apply 
Lightning 0 before weeds exceed labeled height.

Ground Application Methods and Equipment 
Uniformly apply with properly calibrated ground equipment 
in 10 or more gallons of water per acre. A spray pressure 
of 20 to 40 psi is recommended. DO NOT apply when 
wind velocity is greater than 10 mph. (See SENSITIVE 
CROP PRECAUTIONS section for application guidelines 
near sensitive crops.) 
To ensure thorough coverage, a minimum of 10 gallons of 
water per acre is recommended when applying 
Lightning lll 0 herbicide to minimum till or no-till 
CLEARFIELOGD'corn. Use higher gallonage for fields with 
dense vegetation or heavy crop residues. Flat-fan nozzle 
tips are recommended for postemergence applications. 
Avoid overlaps when spraying. 
Ground Boom Spray Drift Requirements 
• Applicators are required to use a nozzle height below 
4 feet above the ground or plant canopy and coarse or 
coarser droplet size (ASABE S572) or, if specifically using 
a spinning atomizer nozzle, applicators are required to 
use a volume mean diameter (VMO) of 385 microns or 
greater. 
• Applications with wind speeds greater than 10 mph are 
prohibited. 
• Applications into temperature inversions are prohibited. 
Aerial Application Methods and,Equipment 
Uniformly apply with properly calibrated aerial equipment in 
5 or more gallons of water per acre. Addition of a nonionic 
surfactant AND fertilizer solution are required for optimum 
weed control. Apply a nonionic surfactant at the rate of 
1 quart per 100 gallons ofspray solution OR a crop oil 
concentrate at the rate of 1 .25 gallons per 100 gallons of 
spray solution, AND a liquid fertilizer at the rate of 
1 .25 gallons per 100 gallons of spray solution (see direc­
tions under MIXING INSTRUCTIONS.) 
To avoid injury to sensitive crops from drift, aerial applica­
tors must adhere to the following SPECIAL AERIAL USE 
DIRECTIONS AND PRECAUTIONS.

required to use a very coarse or coarser'droplet size or, if 
specifically using a spinning atomizer nozzle, applicators 
are required to use a,VMO of 475 microns or greater for 
release heights above 10 feet. Applicators must consider 
the effects of nozzle orientation and flight speed when 
determining droplet size. 
• Nozzles must be pointed toward the rear of the aircraft. 
The downward angle of the nozzle should not be greater 
than 20 degrees. 
• Nozzle height above ground must be a maximum of 
10 feet. 
• To minimize wing-tip vortex roll, nozzles or spray boom 
must not be located any closer to end of wing or rotor 
6 
than three-fourths the distance from the center of the 
aircraft. 
• The boom length must not exceed 90% of the rotor 
blade diameter to reduce spray drift. 
• Use a maximum spray pressure of 40 psi. 
• A buffer zone must be established between the area to 
be sprayed and sensitive crops. 
• Applicators are required to use upwind swath 
displacement. 
• Applications with wind speeds less than 3 mph and with 
wind speeds greater than 10 mph are prohibited. 
• DO NOT spray when wind velocity is greater than 5 mph. 
Coarse sprays (larger droplets) are less likely to drift. 
• Applications into temperature inversions are prohibited. 
Applicator is responsible for any loss or damage that 
results from spraying Lightning 0 in a manner other than 
recommended in this label. In addition, applicator must 
follow all applicable state and local regulations and ordi­
nances in regard to spraying. DO NOT use aerial equip­
ment to apply Lightning 0 when sensitive crops and 
plants are growing in the vicinity of area to be treated. 
SENSITIVE CROP PRECAUTIONS 
Lightning 0 may cause injury to desirable trees and 
plants, particularly beans, cotton, flowers, fruit trees, 
grapes, ornamentals, peas, potatoes, soybeans, sugar 
beets, sunflowers, tobacco, tomatoes and other broadleaf 
plants when contacting their roots, stems or foliage. These 
plants are most sensitive to Lightning 0 during their devel­
opment or growing stage. 
FOLLOW THE PRECAUTIONS LISTED BELOW WHEN 
USING Lightning 0: 
• DO NOT treat areas where either possible downward 
movement into the soil or surface washing may cause 
contact of Lightning 0 with roots of desirable plants 
such as trees and shrubs. 
• Avoid making applications when spray particles may be 
carried by air currents to areas where sensitive crops and 
plants are growing. DO NOT spray near sensitive plants if 
wind is gusty or in excess of 1 0 mph and m(~vjr;}O '!r, the 
direction of nearby sensitive crops. However,Ualways

Select nozzles that are designed to produce giirlifiiel 
amounts of fine spray particles (less than 200 rlilcrons). 
Examples of nozzles designed to produce C03rSE:>sprays 00 0 
via ground application equipment are 
Delavan GD Raindrop, Spraying SystemsXR (excluding 
110
0 
tips) flat fans, Turbo Teejet lll, Turbo Floodjetlll, or 
large capacity flood nozzles such as D1 0, TK10, or 
greater capacity tips. Keep the spray pressure at or 
below 20 psi and the spray volume at or above 
20 gallons per acre, unless otherwise required by the 
manufacturer of drift-reducing nozzles. Consult your

spray nozzle supplier concerning the choice of drift­
reducing nozzles. 
• Agriculturally approved drift-reducing additives may be 
used. 
• To avoid injury to desirable plants, equipment used to 
apply Lightninglll D herbicide should be thoroughly 
cleaned (see CLEANING SPRAY EQUIPMENT) before 
reusing to apply any other chemicals. 
. Additives 
Ground, postemergence applications of Lightning 0 
require the addition of an ADJUVANT AND a NITROGEN 
FERTILIZER SOURCE. 
ADJUVANTS 
Surfactants - cleared for application to growing 
crops. Use a nonionic surfactant containing at least 80% 
active ingredient. Apply the surfactant at the rate of 1 quart 
per 100 gallons. An organo-silicone surfactant may be 
used in place of a non ionic surfactant. 
OR 
Crop Oil Concentrate. The use of a petroleum-based or 
vegetable seed-based oil concentrate or methylated seed 
oil with Lightning D is permitted and may be beneficial 
under the following conditions: 
1 . Hot arid environmental conditions exist, when weeds 
may be under stress and less susceptible to herbicide 
applications. 
However, when periods of cold and wet weather OR hot i 
and humid weather exist, the use of a non ionic surfactant 
instead of crop oil concentrate is recommended. 
Apply crop oil concentrates at the rate of 1 gallon per 
100 gallons of spray solution (1 % voL/voL). 
AND 
NITROGEN FERTILIZER SOURCE 
Recommended nitrogen based fertilizers include liquid fer­
tilizers (such as 28%N, 32%N or 10-34-0) at the rate of 1-2 
quarts per acre. Use the higher rate when weeds are under 
moisture or temperature stress. Instead of a liquid fertilizer, 
spray grade ammonium sulfate may be used at the rate of 
2.5 pounds per acre. 
Alternatively, the use of proprietary products that contain 
both a nonionic surfactant and a nitrogen source that 
provide equivalent spray additive activity to those additives 
mentioned above, may be used with Lightning D. Other 
premixes containing a surfactant and a nitrogen source 
may be used as long as performance and rate guidelines 
for surfactant and nitrogen amounts are met. 
Mixing Order 
DO NOT use liquid fertilizer as a carrier (use water only) for 
postemergence applications of Lightning D. 
WATER 
1. RII the spray tank 1/2 to 3/4 full with clean water. 
7 
2. Add the required amount of Lightning 0 to the spray 
tank while agitating. 
3: After the Lightning D has visibly dispersed, add spray 
additives and fill the remainder of the tank with water. 
An antifoam agent may be added if needed. 
SLURRY PREPARATION 
Lightning D may be slurried prior to addition to the spray 
tank. 
1 . Add 1 to 2 pounds of product per gallon of water . 
2. Agitate slurry for 10-15 minutes or until product is 
completely in solution. 
3. Transfer slurry to spray tank (begin spray tank agita-
tion) filled 1/2 to 3/4 full with clean water. 
TANK MIX PREPARATION 
When tank mixing Lightning D with recommended herbi­
cides, add the other herbicides and other components in 
the following order, while agitating: 
1. Fill spray tank 1/2 to 3/4 full with clean water. 
2. Add Lightning D and thoroughly mix. 
3. Add other aqueous solution products. 
4. Add other soluble packet products and thoroughly 
mix. 
5. Add WP (wettable powder), DG (dispersible granule), 
DF (dry flowable), or LF (liquid flowable) formulations. 
6. Add EC (emulsifiable concentrate) products. 
7. Add surfactant to the spray tank. 
S. Add liquid fertilizer. 
9. While agitating, fill the remainder of the tank with 
water. 
General Tank Mixing Information 
When Lightning D is used in combination with another 
herbicide, refer to the respective label for rates, spray addi­
tives, methods of application, proper timing, weeds con­
trolled, restrictions and precautions. ftJways use in 
accordance with the more restrictive label restrictions and 
precautions. Lightning D cannot be mixed with any 
product containing a label prohibiting such mixtures. No 
labeled dosages should be exceeded. a)

ROTATIONAL CROPS GUIDELINE 
Use of Lightning® 0 herbicide in accordance with label 
directions is expected to result in normal growth of rota­
tional crops in most situations; however, various environ­
mental and agronomic factors make it impossible to 
eliminate all risks associated with the use of this product 
and, therefore, rotational crop injury is always possible. The 
following rotational crops may be planted after applying 
Lightning 0 at the recommended rate in corn. Planting 
earlier than the recommended interval may result in crop 
injury.

**Following forty months after a LightningD application, and before 
any crop not listed in the ROTATIONAL CROPS GUIDELINE, a 
successful field bioassay must be completed. The field bioassay .. 
consists of a test strip of the intended rotational crop planted across 
the previously treated field and grown to maturity. The test strip should 
include low areas and knolls, and include variations in soil such as 
type and pH. If no crop injury is evident in the test strip rotational crop 
may be planted the following year. 
Only rotational crops harvested at maturity may be used for 
feed or food. 
BASF recommends that products containing imazethapyr 
(Pursui~, Pursui~ Plus EC) should NOT be applied to 
CLEARFIELD corn the same year as Lightning 0 or 
injury to follow crops may occur. 
If the field is limed to adjust pH prior to planting rotational 
crops not listed in the ROTATIONAL CROPS 
GUIDELINE, apply the lime at least 12 months prior to 
planting the rotational crop. 
EXCEPTIONS TO ROTATIONAL CROPS GUIDELINE 
• If corn is furrow irrigated, till the soil prior to planting 
winter wheat or barley. The beds should be broken up 
and the soil mixed with tillage equipment set to cut 4-
6 inches deep.

Crop-specific Information 
CLEARFIELD Corn 
Lightning D can be applied postemergence (including 
spike stage) on CLEARFIELD corn hybrids. 
Sequential Herbicide Combinations 
with Lightning D 
Lightning D controls many grass and broadleaf weed 
species. However, Lightning D is best utilized in mUltiple­
pass weed control programs when Lightning 0 is applied 
sequentially after a soil surface-applied herbicide (i.e. 
preplant, preplant incorporated or preemergence) or after 
an early postemergence-applied herbicide.
