STATEMENT OF PRACTICAL TREATMENT 
IF SWALLOWED: Drink t or 2 glasses of water and induce vomrting by touching back of throat whh finger. Never give anything by 
mouth to an unconscious or convulsing person. Call a physician and follow General advice listed below. 
IF IN EYES: Flush eyes with plenty of water. Get medical attention if irritation persists. 
IF ON SKIN: Wash thoroughly with soap and water. 
IF INHALED: Call a physician and follow General advice listed below 
GENERAL 
Contact a physician immediately in all cases of suspected poisoning. If breathing stops, establish an airway, start .ortijicial resporation. 
and provide oxygen. Make certain to remove all sources of continuing contam;nation. Remove clothing and wash skin and hair 
immediately wrth large amounts of water. Transport the patient to a physician or hospital immediately and SHOW A COPY OF THIS 
LABEL TO THE PHYSICIAN. 
NOTE TO PHYSICIAN 
LARVIN~ thiodicarb is an oxime carbamate insecticide, which IS a cholinesterase Inhibitor. Overexposure to this substance may cause 
toxic signs and symptoms due to stimulation of the cholinergic nervous system. These effects of overexposure are spontaneously 
and rapidly reverSible. 
Specdic treatment consists of parenteral atropine sulfate. Caution should be maintained to prevent ove, atropinization. Mild cases 
may be given 1 to 2 mg intramuscularly every 10 minutes until full atropinizatIOn has been achieved and repeated thereafter whenever 
symptoms reappear. Severe cases should be given 2 to 4 mg Intravenously every 10 minutes until fully atropinized, then 
intramuscularly every 30 to 60 minutes to maintain the effect for at least 12 hours. Dosages for children should be approproately 
reduced. Complete recovery from overexposure IS to be expected wrthin 24 hours. 
Narcotics and other sedatives should not be used. Further. drugs like 2-PAM (pyridine-2-aldoXime methiodide) are NOT recomn'ended 
unless organophosphate IntoxicatIOn is also suggested. 
To aid in confirmation of a diagnosis, urine samples should be obtained wrth,n 24 hours of exposure and immediately frozen. Analyses 
will be arranged by RhOne-Poulenc Ag Company. 
ConsunatlOn on therapy can be obtained at all hours by calling the Rh6ne-Poulenc emergency number: 1 -!l00-334-7577 .

- GENERAL INFORMATION 
LARVIN" 75WP is a wenable powder concentrate formulation of Thiodicarb Insecticide that readily disperses i" water for purposes of 
spraying by ground or air equipment. Directions on this label are based on tests and field experience relating to effectiveness, impact 
on environment and residues remaining in food and feed. READ THE ENTIRE LABEL AND OBSERVE ALL LABEL DIRECTIONS AND 
PRECAUTIONS BEFORE USE. 
GENERAL DIRECTIONS 
SPRAY PREPARATION 
Remove oil, rust, scale, pesticide residues and other foreign matter from sprayer and strainer. Flush with clean water. Use 50 mesh 
screens or ~Iotted strainers in spray system. To prepare for spraying, fill tank approximately one-naH full of water. Add LARVIN" 
75WP InsecticiC:e and mix thoroughly by nechanical or hydraulic agitation. Finish filling tank with water to desired volume and 
thoroughly mix. Do not store spray mixture for prolonged periods. If tank-mixes are to be used, LAAVIN" 75WP must be fully 
dispersed in water first, followeU by the addl·ion of the Intended tank-mix material. 
APPLICATION 
Begin application when insect populations :each recognized economic threshold levels. Consult the Cooperative Extension Service, 
Professional Consuttants or other qualdied authorities to determine appropriate threshold levels for treatment in your area. Apply a 
minimum finished spray volume of 3 gallons per acre by air or 15 gallons per acre by ground for sweet corn. Repeat application as 
needed to maintain control. Use higher dcsage rates for heavier infestations or larger larvae. Use lower rates for light to moderate 
infestations. 
To clean the sprayer after use, drain and fluc.h with water. 
DIRECTIONS FOR USE THROUGH SPRINKLER IRRIGATION SYSTEMS 
Apply this product only through sprinkler Irrigation systems including center pivot and solid set. Do not apply this product through any 
other type of irrigation system. 
SPRAY PREPARATION 
Remove scale, pesticide residues, and other foreign matter from the chemical tank and entire injector system. Flush with clean water. 
APPLICATION INSTRUCTIONS 
First prepare a suspension of LARVIN" brand Thiodicarb Insecticide 75WP in a mix tank. Fill tank with 112 to 3/4 the deSired amount of 
water. Stan mechanical or hydraulic agitation. Add the required amount of LARVIN" brand 75WP, and then the remaining volume of 
water. (Suspension concentrations using the appropriate dosage per acre recommended on this label of LARVIN" brand 75WP per t to 
4 gallons of water are rocommended).Then set sprinkler to deliver O.t to 0.3 inch of water per acre. Stan sprinkler and undormly inject 
the suspension of LARVIN" brand 75WP into the ;rrigatlOn water line so as to deliver the desired rate per acre. The suspension of 
LARVIN" brand 75WP should be injected with a positive displacement pump into the main line ahead of a right angle turn to insure 
adequate mixing. If you should have any other questrons about calibration, you should contact State ExtenSion Service specia,ists, 
equipment manufacturers or other expens. 
NOTE: When treatment with LAAVIN" brand Thiodicarb Insecticide 75WP has been completed, further field irrigation over the treated 
area should be avoided for 24 to 48 hours to prevent washing the chemical off the crop. 
GENERAL PRECAUTIONS FOR APPLICATIONS THROUGH SPRINKLER IRRIGATION SYSTEMS 
Maintain continuous agitation in mix tank dUring mixing and application to assure a undorm suspension. 
Greater accuracy in calibration and distributIOn Will be achieved by injecting a larger volume of a more dilute solution per unit time. 
The system must contain a functional check valve. vacuum relief valve, and low pressure uain appropriately located on the irrigation 
pipeline to prevent water source contamination irom backilow. The pesticide Injection pipeline must contain a functional, automatic, 
quick-closlng check valve to prevent the flow of fluid back toward the injection pump. The pesticide injection pipeline must also contain 
a functional, normally closed solenoid-operated valve :ocated on the intake Side of the injection pump and connected to the system 
interlock to prever,t fluid from being withdrawn from the supply tank when the irrigation system is either automatically or manually 
shutdown. The system must contain functional interlocking controls to automatically shut off the pesticide Injection pump when the 
water pump motor stops. The irrigation line or water pump must include a functional pressure SWitch which will stop the water pump 
motor when the water pressure decreases to the point where pesticide distribution is adversely affected. Systems must use 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. Do not apply when wind speed.Clvors drift beyond 
the area Intended for treatment. • ••••••

COMPATIBILITY 
LARVIN" 75WP, when diluted w~h ai' equal volume of water, is p ,ysically compatible with a wide range of commonly used spray 
products, but the full range of compatibil~ies under local conditions s not known. Therefore, it is essential that before using any tank 
mixture of LARVIN" 75WP Insecticide, the compatibility of the IT.ixture be established. Add a small amount of LARVIN" 75WP 
Insecticide to an equal volume of water in a small container and th'.n add the other pesticide or spray product and mix thoroughly. DO 
NOT USE MIXTURES THAT CURDLE, PRECIPITATE, OR GREJ,SE. THIS PRODUCT IS NOT MISCIBLE WITH VEGETABLE OIL 
DILUENTS. TANK MIXlURES SHOULD BE USED WITHIN 6 HOUF.S AFTER MIXING. 
NOTE: LARVIN Thiodicarb Insecticide is hydrolytically sensitive co degradation of active ingredient by strong acids, strong bases, and 
certain heavy metal oxides and satts of certain fungicides such us Maneb, Mancozeb, Copper Count N·8, and Bordeaux mixture. DO 
NOT USE lARVIN 75"'WP INSECTICIDE IN SPRAY MIXTURES WITH THE ABOVE METAL PRODUCTS. DO NOT ADD LARVIN" 75WP 
TO WATER WITH pH VALUES BELOW 3.0 OR ABOVE 8.5. H necessary, water should be buffered within this range before adding
