GENERAL INFORMATION 
Liquid Lightning!!> herbicide can be applied postemer­
gence (including spike stage) on CLEARFIELD!!> corn 
hybrids. Apply only on selected field corn hybrids 
(CLEARFIELD corn) warranted by the seed company to 
possess resistance/tolerance to direct application of certain 
imidazolinone herbicides. DO NOT apply 
Liquid Lightning to corn hybrids that lack resistance/tol­
erance to imidazolinone herbicides. Cont~ct your seed 
supplier, chemical dealer or BASF to obtain information 
regarding CLEARFIELD corn hybrids. 
Liquid Lightning kills weeds by root and/or foliar uptake 
and rapid translocation to the growing points. Adequate 
soil moisture is important for optimum Liquid Lightning 
activity. When adequate soU moisture is present, 
Liquid Lightning will provide'residual control of suscepti­
ble germinating weeds; activity on established weeds will 
depend on the weed species and the location of its root 
system in the soil. 
Use of Liquid Lightning in accordance with label direc­
tions is expected to result in normal growth of rotational 
crops in most situations. However, various environmental 
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. Under some condi­
tions (such as heavy texture soil, high organic matter, low 
pH or low rainfall) Liquid Lightning may cause injury to 
subsequent planted crops. See ROTATIONAL CROPS 
section ofthis label for recommended rotation intervals to 
sensitive crops. 
Crops growing under stressful environmental conditions 
can exhibit various injury symptoms that may be more pro­
nounced if herbicides are used. Corn plants treated with 
Liquid Lightning may exhibit yellowing on new growth. 
Such effects occur infrequently and are temporary. Normal 
growth and appearance should resume within 1 to 
2 weeks.

( &fI I 
Naturally occurring olutypes* 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 herbicides with the ALS/AHAS 
enzyme-inhibiting mode of action include the imidazoli­
nones (e.g. Pursuit!!> herbicide, ScepterlB> herbicide, 
etc.), the sulfonylureas (e.g. Accent!!>, Basis!!>, Classic!!>, 
Concert!!>, Permit!!>, Pinnacle!!>, etc.) the sulfonamides 
(e.g. Broadstrike!!>, etc.) and the pyrimidyl benzoates (e,g. 
Staple!!>, etc.). If naturally occurring biotypes are present in 
a field which are resistant to this herbicide, 
Liquid Lightning 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. 
Replanting: If replanting is necessary in a field previously 
treated with Liquid Lightning, the field may be replanted 
only to CLEARFIELD corn. Rework the soil no deeper 
than the treated zone. DO NOT apply a second treatment 
of Liquid Lightning. 
MIXING INSTRUCTIONS 
POSTEMERGENCE APPLICATIONS OF Liquid Lightning 
REQUIRE THE ADDITION OF A SURFACTANT AND A 
NITROGEN FERTILIZER SOLUTION1 • 
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 nonionic surfactant. 
AND 
FERTILIZER 
Recommended nitrogen-based fertilizers include liquid fer­
tilizers (such as 28%N, 32%N or 10-34-0) at the rate of 1 
to 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. , ,

TANK MIX COMBINATIONS WITh..JTHER 
HERBICIDES 
When tank mixing Liquid Lightning~ herbicide with rec­
ommended herbicides, 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 soluble packet products and thoroughly mix. 
3. Add WP (wettable powder), DG (dispersible granule), 
OF (dry flowable), or LF (liquid flowable) formulations not 
ih soluble packets. 
4. Add Liquid Lightning and thoroughly mix. 
5. Add other aqueous solution products. 
6. Add EC (emulsifiable concentrate) products. 
7. Add surfactant to the spray t?-nk. 
8. Add liquid fertilizer. 
9. While agitating, fill the remainder of the tank with water. 
When Liquid Lightning is used in combination with 
another herbicide, refer to the' respective label for rates, 
methods of application, proper timing, weeds controlled, 
restrictions and precautions. Always use in accordance 
with the more restrictive label restrictions and precautions. 
No label dosages should be exceeded. 
PROCEDURE FOR CLEANING SPRAY EQUIPMENT 
To avoid injury to sensitive crops, spray equipment used for 
Liquid Lightning applications must be drained and thor­
oughly cleaned with water before being used to apply other 
products. 
SPRAYING INSTRUCTIONS

required to use a very coarse or coarser droplet size or, if 
specifically using a spinning atomizer nozzle, applicators 
are required to use a VMD 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. 
• Applicators are required to use upwind swath 
displacement. 
• The boom length must not exceed 60% of the wingspan 
or 90% of the rotor blade diameter to reduce spray drift .. 
• Applications with wind speeds less than 3 mph and with 
wind speeds greater than 10 mph are prohibited. 
• Applications into temperature inversions are prohibited. 
Aerial Applications. Uniformly apply with properly cali­
brated aerial equipment in 5 or more gallons of water per 
acre. Addition of a nonionic surfactant AND fertilizer solu­
tion are required for optimum weed control; apply a non­
ionic surfactant at the rate of 1 quart per 100 gallons of 
spray mixture AND a liquid fertilizer at the rate of 1 quart 
per acre. (See directions 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. 
• Nozzles must be pOinted toward the rear of the aircraft. 
The downward angle of the nozzle should not be greater 
than 20 degrees. 
• Use a maximum spray pressure of 40 psi. 
• A buffer zone must be established between the area to 
be sprayed and sensitive crops. 
Applicator is responsible for any loss or damage which 
results from spraying Liquid Lightning in a manner other 
than recommended in this label. In addition, applicator 
must follow all applicable state and local regulations and 
ordinances in regard to spraying. 
SENSITIVE CROP PRECAUTIONS 
Liquid Lightning 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 !oliag~. These 
plants are most sensitive to Liquid Lightnin~ d'.1:l1::J their

to drift out of the target area than fine sprays. 
• Use coarse sprays to avoid potential herbicide drift. 
Select nozzles which are designed to produce minimal 
amounts of fine spray particles such as Spraying 
Systems XR flat fans. A spray pressure of 20 psi and 
spray volume at or above 20 gpa are recommended to 
reduce drift to sensitive crops. 
• Agriculturally approved drift-reducing additives may be 
used. 
• To avoid injury to desirable plants, equipment used to 
apply Liquid Lightning® herbicide should be thoroughly 
cleaned (see PROCEDURE FOR CLEANING SPRAY 
EQUIPMENT) before reusing to apply any other 
chemicals. 
USE RATE 
Apply Liquid Lightning at a broadcast rate of 4 fluid 
ounces per acre. At this broadcast rate, one gallon of 
Liquid Lightning will treat 32 acres of CLEARFIELD® 
corn. 
NOTE: Only one application of Liquid Lightning may be 
made during the growing season. 
Not for use in California or New York. 
APPLICATION INSTRUCTIONS 
Liquid Lightning is effective in controlling weeds in con­
servation tillage as well as in conventional production 
systems. Ensure that all w8E.ld,s are controlled by tillage or 
burndown herbicide prior to pianting corn. Apply 
Liquid Lightning as a postemergence treatment to 
CLEARFIELD corn when crop and weeds are actively 
growing. For optimal weed control, apply Liquid Lightning 
before weeds exceed labeled height. If the corn is greater 
than 20-inches tall or if the crop canopy prevents adequate 
weed coverage, Liquid Lightning must be applied with 
drop nozzles, post-directed onto weeds. DO NOT apply 
within 45 days of harvest. More restrictive crop growth 
stage limitations of tank mix partners must be followed. 
A nonionic surfactant and a liquid fertilizer must be added 
to the spray solution for optimum weed control activity. See 
additive information under MIXING INSTRUCTIONS for 
specific instructions. 
For maximum weed control, cultivate 7 to 10 days follow­
ing Liquid Lightning application. This timely cultivation will 
enhance residual weed control, especially under dry 
conditions. 
If air temperatures reach or stay below 50° F for 10 or more 
hours, delay a Liquid Lightning application for 48 hours 
from the time temperatures increase above 50
0 
F. 
Unusually cool temperatures (50
0 
F or less) reduce photo­
synthesis and transpiration and thus reduce the uptake 
and translocation (and effectiveness) of Liquid Lightning 
in weeds and may enhance crop response.

Liquid Lightning S~'UUld be applied a minimum-of one c:: II 
hour before rainfall or overhead irrigation. 
SEQUENTIAL HERBICIDE COMBINATIONS WITH 
LIQUID LIGHTNING 
Liquid Lightning controls many grass species. However, 
when heavy grass pressure is anticipated, a soil application 
of any grass herbicide underlay (such as Prowl®, Axiom®, 
Dual" Magnum'®, Epic®, Eradicane®, Harness®, or 
Surpass®) is recommended. Liquid Lightning may also 
be used in sequential programs with registered burndown 
herbicides .

Liquid Lightning is active against many broadleaf and 
grass species. For long-term weed management, use two 
herbicides with different modes of action to reduce the 
potential for weed resistance. 
When Liquid Lightning is used in combination with 
another herbicide, refer to the respective label for rates, 
methods of application, proper timing, weeds controlled, 
restrictions and precautions. Always use in accordance 
with the more restrictive label restrictions and precautions. 
No label dosages should be exceeded. 
WEEDS CONTROLLED 
When applied as directed at the broadcast rate of 4 fluid 
ounces per acre, Liquid Lightning will control or reduce 
competition from the weeds listed in Table 1.

1See EXCEPTIONS TO ROTATIONAL CROPS 
GUIDELINES. 
Following forty months after a Liquid Lightning applica­
tion, and before any crop not listed in ROTATIONAL 
CROPS, 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 eviaent in the test strip, the rota­
tional crop may be planted the following year. 
If the field is limed to adjust pH prior to planting rotational 
crops not listed in ROTATIONAL CROPS, apply the lime 
at least 12 months prior to planting the rotational crop. , 
EXCEPTIONS TO ROTATIONAL CROPS GUIDELINES 
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- to 6-inches 
deep. 
Corn inbred lines: Corn inbred seed lines may be planted 
the year following an application of Liquid Lightning. Due 
to the proprietary nature of seed production, BASF has not 
been given access to the inbred data. Growers are directed 
to contact the seed company for information and recom­
mendations regarding the planting of corn grown for seed 
in fields treated with Liquid Lightning the previous year. 
Because growing conditions, environmental conditions, 
and grower practices are beyond the control of BASF, TO 
THE EXTENT CONSISTENT WITH APPLICABLE LAW, 
ALL RISKS AND CONSEQUENCES ASSOCIATED 
WITH PLANTING SEED CORN INBREDS INTO FIELDS 
TREATED PREVIOUSLY WITH LIGHTNING SHALL BE 
ASSUMED BY THE USER.

Use of Uquid Ligh',ng in a~ordance with label dir~c: 
tions is expected to result in normal growth of rotational 
crops in most situations. However, various environmental 
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. 
PRECAUTIONS 
In the event of a crop loss due to weather, CLEARFIELD® 
corn seed hybrids can be replanted following an applica­
tion of Liquid Lightning. If Liquid Lightning was tank 
mixed with other herbicides, the label restrictions for these 
herbicides must also be followed. 
There should be an interval of at least 45 days between an 
application of Liquid Lightning and corn harvest (silage, 
fodder, or grain). DO NOT graze or feed treated corn 
forage, silage, fodder, or grain for at least 45 days after an 
application of Liquid Lightning. 
Only rotational crops harvested at maturity may be used for 
feed or food. 
BASF recommends products containing imazethapyr 
(Pursuit® herbicide, Pursuit® Plus EC herbicide) NOT 
be applied to CLEARFIELD corn the same year as 
Liquid lightning or injury to followcrops may occur. 
All soil insecticides, including labeled banded or infurrow 
applications, may be used in combination with 
CLEARFIELD corn hybrids and Liquid Lightning. 
Terbufos may be applied to CLEARFIELD corn hybrids 
with an at -cultivation treatment 7 days or more after 
Liquid Lightning has been applied. 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, environ­
mental conditions, grower practices and the specific genet­
ics of each hybrid tolerance to herbicide and insecticide 
applications. 
This label must be in the possession of the user at the time 
of herbicide application.
