SUPPLEMENTAL LABELING 
LORO:xe DF HERBICIDE 
FOR USE ON CARROTS IN CHEMIGA­
TION SYSTEMS IN THE STATES OF 
CALIFORNIA, IDAHO, OREGON AND 
WASHINGTON

LOROX DFHERBICIDE 
Reg. No. 352-394 
FOR USE ON CARROTS IN CHEMlGATION SYSTEMS 
DIRECTIONS FOR USE 
It is a violation of federal law to use this product in a manner 
inconsistent with its labeling. 
In the states of California, Idabo, Oregon and Washington, 
Lorox DF is recommended for use on carrots when applied by 
chemigation systems. 
PREEMERGENCE APPLICATION 
Make a single application of 1 to 2 lbs. per acre. Subsequent 
postemergence applications may be made. Trial on a small area 
to evaluate unanticipated problems is suggested. Injury may 
potentially occur from this application. 
POSTEMERGENCE APPLICATION 
Apply 1 lI2 to 3 Ibs per acre after carrots are at least 3" tall. 
Apply before grasses exceed 2" in height and before broadleaves 
exceed 6" in height. Repeat application may be made. 
PRECAUTIONS 
Do not apply within 14 days of harvest. 
Do not exceed 3 Ibs. total product per acre per season. 
Do not make more than 3 applications by any method per acre 
per season. 
Do not use surfactant. 
CHEMIGATION 
LOROX DF can be applied using center pivot, lateral move, 
solid set, or hand move irrigation systems. Do not apply 
LOROX DF using any other type of irrigation system. Check 
irrigation systems to insure uniform application of water to all 
areas. Failure to apply LOROX DF uniformly may result in 
crop injury and/or poor weed control. 
LOROX DF may be mixed in a supply tank with water, fertil­
izer, or other appropriate agricultnral chemicals. Maintain con­
tinuous agitation in the injection nurse tanks during application. 
For solid set and hand move irrigation systems, apply LOROX 
DF at the beginning of the set and then apply 1/3 to 1 " of water· 
for activation (sandy soils apply at least 113", sandy loams apply 
at least lI2", silt soils apply at least 3/4", clay soils apply at least 
1 "). For center pivot and lateral move irrigation systems, apply 
LOROX DF in lI3 to I" of water for activation as a continuous 
injection (sandy soils apply at least 1/3", sandy loams apply at 
least 112", silt soils apply at least 3/4", clay soils apply at least 
I"). If you have questions about calibrating chemigation equip­
ment, contact State Extension Service specialists, equipment 
manufacturers, or other exl"'rts. If the chemigation equipment 
needs adjustment, only the custodian responsible for its opera-· 
tion, or someone under the supervision of that custodian, should 
make the necessary adjustments. 
IRRIGATION SYSTEM REQUI~MENTS 
The irrigation system must contain the following: 
- • a functional check valve 
• vacuum relief valve 
• a low pressure drain (to prevent water source 
contamination from bacldlow; should be located on the . 
irrigation pipeline) 
* functional interlocking controls (to automaticall>: 
shut-off the pesticide injection pump when the water 
pump motor stops) 
• a metering pump, such as a positive displacement 
injection pump (e.g., diaphragm pump) effectively 
designed and constructed of materials that are 
compatible with pesticides and capable of being fitted 
with a system interlock. 
The pesticide injection pipeline must contain the following: 
* a functional, automatic, quick-closing check valve (to 
prevent the flow of fluid back toward the injection 
pump) 
* a functional, solenoid-~p~rated valve (normally closed) 
located on the intake side of the injection pump 
(should be connected to the system interlock to prevent 
fluid from being withdrawn from the supply tank when 
the irrigation system is shut down either automatically 
or manually)

( 
The irrigation line or water pump must include a functional pres­
sure switch that will stop the water pump motor when pesticide 
distribution is adversely affected by a decrease in water pressure. 
CHEMIGATION PRECAUTIONS 
Distributing treated water in an uneven manner can result in crop 
injury, lack of effectiveness, or over-tolerance pesticide residues 
in the crop. Therefore, to ensure that the mixture is applied 
evenly at the recommended rate, use sufficient water, and apply 
the mixture for the proper length of time. Do not permit run-off 
during chemigation. 
Do not apply when wind speed favors drift beyond the area 
intended for treatment 
Do not connect an irrigation system (including greenhouse 
systems) used for LOROX DF application £0 ii pnblic water 
system.
