( 35...2- 3 1'( ltCCfE P TED AUG -6 1997 p~ I; .L SUPPLEMENTAL LABELING LORO:xe DF HERBICIDE FOR USE ON CARROTS IN CHEMIGA­ TION SYSTEMS IN THE STATES OF CALIFORNIA, IDAHO, OREGON AND WASHINGTON DuPont Agricultural Products " ...... A Growing Partnership With Nature" 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-prated 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) © 1997 E.

( 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.
