STATEMENT OF PRACTICAL TREATMENT 
IF SWALLOWED: Drir>k 1 or 2 glasses of water and induce vom~ing by touching back of throat w~h finger. Never give anything by 
mouth to an unconscious or convulsing person. Call a physician and follow General advice listed b"low. 
IF IN EYES: Flush eyes w~h plenty of water. Get medical attention if irritation persists. 
IF ON SKIN: Wash thoroughly w~h 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 artdicial respiration, 
and provide oxygen, Make certain to remove all so~'':'~$ 01 continuing contamination. Remove clothing and wash skin and hair 
immediately with large amounts of water. Transport the patient to a physician or hospital immediately and SHOW A COPY OF THIS

NOTE TO PHYSICIAN 
LARVIN" thiodicarb is an oxime carbamate insecticide. which is a cholinesterase ini,ibitor. Overexposure to this substanee may cause 
toxic signs and symptom~ due to stimulation of the cholinergic nervous system. These effects of overex~sure are spontaneously 
and rapidly reversiblo, 
Spec~ic treatment consists of parenteral atropine sulfate. Caution should be maintained to prevent overatropinizatlon. 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 appropnately 
reduced, Complete recovery from overexposure is to be expected within 24 hours. .:. 
Narcotics and other sedatives should not be used. Further, drugs like 2·PAM (pyridine·2·aldo.lme methiodldej areoNQ. recom2tTlrVreZl 
unless organophosphate intoxication is also suggested. • ...: • • 
To aid i.' confirmation of a diagnosis, urine samples should be obtained w~hin 24 hours of exposure and immediately~rozen.

COMPATIBILITY 
LARVIN~ SC Thiodicarb Insecticide, when diluted with an equal volume of water, is physically compatible w~h a wide range of commonly 
used spray products, but the full range of compatibilities under local conditions is not known. Therl/fore, it is essential that before 
using any tank mixture of LARVIN~ SC Insecticide, the compatibility of the mixture be established. A:ld a small amount of LARVIN~ 
SClnsecticide to an equal volume of water in a small container and then add the other pesticide or spray product and mix thoroughly. 
00 NOT USE MIXTURES THAT CURDLE, PRECIPITATE, OR GREASE. THIS PRODUCT IS NOT MISCIBLE WITH VEGETABLE OIL 
DILUENTS. TANK MIXTURES SHOULD BE USED WITHIN 6 HOURS AFTER MIXING. 
NOTE: LARVIN~ Thiodicarb Insecticide is hydrolytically sensitive to degradati<.n of active ingredient by strong acids, strong bases, 
and certain heavy metal oxides and salts of certain fungicides such as Maneb, Mancozeb, Copper Count N·8, and Bordeaux mixture. 
00 NOT USE LARVINe SC INSECTICIDE IN SPRAY MIXTURES WITH THE ABOVE METAL PRODUCTS. 00 NOT ADD LARVI~ SC 
INSECTICIDE TO WATER WITH pH VALUES BELOW 3.0 OR ABOVE 8.5. If necessary, water should be buffered within this range 
before adding LARVIN~ Thiodicarb Insecticide. 
APPLICATION 
Begin application when insect populations reach recognized economic threshold levels. Consult the Cooperative Extension Service, 
Professional Consu~ants or other qual~ied 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 t 5 gallons per acre by ground for sweet corn. Repeat application as 
needed to maintain control. Use higher dosage rates for heavier infestations or larger larvae. Use lower rates for light to moderate 
infestations. 
To cledn the sprayer aiter use, drain and flush 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 residuss, 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 SC Thiodicarb Insecticide in a mix tank. Fil! tank with tl2 to 3/4 the desired amount of 
water. Start mechanical or hydraulic agitation. Add the required amount of LARVIN® SC, and then the remaining volume of water. 
(Suspension concentrations using the appropriate dosage per acre recommended on this label of LARVIN® SC per 1 to 4 gallons of 
water are recommended).Then set sprinkler to deliver 0.1 to 0.3 inch of water per acre. Start sprinkler and uniformly inject the 
suspension of LARVIN~ SC into the irrigation water line so as to deliver the desired rate per acre. The suspension of LARVIN~ SC 
should be injected with a positive displacement pump into the main lone ahead of a right angle turn to insure adequate mixing. If you 
should have any other questions about calibration, you should contact State Extension Service specialists, equipment manufacturers 
or other experts. 
NOTE: When treatment with LARVIN® brand SC Thiodicarb Insecticide 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 continuou, agitation in mix tank during miXing and application to assure a uniform 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 drain appropriately located on the irrigation 
pipeline to prevent water source contamination from backflow. The pesticide injection pipeline must contain a functional. automatic. 
quick-closing 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 located on the ontake side of the injection pump and connected to the system 
interlock to prevent fluid from being withdrawn from the supply tank when the irrigation system is either autor.latically or manually 
shutdown. The system must contain functional interlocking controls to automatically shut off the pesticide injectiog pump when the 
water pump motor stops. The irrigation line or water pump must include a functional pressure switch which will st!>p"Ihe water pump 
motor when the water pressure decreases to the point where pesticide distribution is adversely affected. Systems l'lust use a ..-~ 
pump. such as a positive displacement injection pump (e.g., diaphragm pump) effectively designed and constructe'; 06 mate~alsthat 
are compatible w~h pesticides and capable of being fitted with a system interlock. Do not apply when wind spee~'avc!rs dri~&vllQnd 
the area intended for treatment. • •••• 
•• • Do not apply when wind speed favors dlift, when system connect'~n or fittings leak. when nozzles do not provide"ntf~LI1'I distriBationoor

Crop injury. lack of effectiveness. or illegal pesticide residues In the crop may result from non·un~orm distribution·~.t'e;Oed water .• 
•••••• Allow sufficient time for pesticide to be flushed through all lines and all nozzles before turning off irrigation tiater. A pIla~
