ENVIRONMENTAL HAZARDS
This pesticide is toxic to wildlife and aquatic invertebrates. This product is highly toxic to bees and other
pollinators exposed to direct treatment or residues on blooming crops or weeds. Do not apply this
product or allow it to drift to blooming crops or weeds if bees or other pollinating insects are foraging in
the treatment area.
Do not apply directly to water, or to areas where surface water is present or to intertidal areas below the
mean high water mark. Do not contaminate water when disposing of equipment washwater or rinsate.
Dimethoate is known to leach through soil into ground water under certain conditions as a result of label
use. Use of this chemical in areas where soils are permeable, particularly where the water table is
shallow, may result in ground-water contamination.
This product may contaminate water through drift of spray in wind. This product has a high potential for
runoff for several days after application. Poorly draining soils and soils with shallow water tables are
more prone to produce runoff that contains this product.
A level, well-maintained vegetative buffer strip between areas to which this product is applied and surface
water features such as ponds, streams, and springs will reduce the potential for contamination of water
from rainfall-runoff. Runoff of this product will be reduced by avoiding applications when rainfall is
forecasted to occur within 48 hours.
A vegetative filter strip constructed and maintained in accordance with the 2000 Natural Resources
Conservation Service publication "Conservation Buffers to Reduce Pesticide Losses"
(http://permanent.access.gpo.goV/lps9018/www.wcc.nrcs.usda.gov/water/quality/common/pestmgt/files/n
ewconbuf.pdf) will significantly reduce the potential for contamination of water from rainfall-runoff.
Protective information may be obtained from your cooperative agricultural extension service.

DIRECTIONS FOR USE -" c
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. 1.^.11
This product is for use in commercial setting only. Use in residential settings is prohibited.
Do not apply this product in a way that will contact workers or other persons, either directly or through
drift. Only protected handlers may be in the area during application. For any requirements specific to
your State or Tribe, consult the agency responsible for pesticide regulation.

AGRICULTURAL USE REQUIREMENTS ,
Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR
Part 170. This Standard contains requirements for the protection of agricultural workers on farms, forests,
nurseries, and greenhouses, and handlers of agricultural pesticides. It contains requirements for training,
decontamination, notification, and emergency assistance. It also contains specific instructions aYid
exceptions pertaining to the statements on this label about personal protective equipment (PPE), and
restricted-entry interval. The requirements in this box only apply to uses of this product that are coveted
by the Worker Protection Standard. »
Do not enter or allow worker entry into treated areas during the restricted-entry interval (REI). The REI for
a specific crop is listed in the directions for use associated with that crop.
PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and
that involves contact with anything that has been treated, such as plants, soil, or water, is: coveralls worn
over long-sleeve shirt and long pants, chemical-resistant gloves made of any waterproof material,
chemical-resistant footwear plus socks, and chemical-resistant headgear (if overhead exposure).
Notify workers of the application by warning them orally and by posting warning signs at entrances to
treated area.
Aerial Application:
Automatic flagging devices must be used whenever feasible.
If human flaggers are employed, they must wear the protective clothing and respirator specified on this
label.
REQUIREMENTS FOR REDUCING SPRAY DRIFT
Do not apply under circumstances where possible drift to unprotected persons or to food, forage, or other
plantings that might be damaged or crops thereof rendered unfit for sale, use, or consumption can occur.
1. Use the largest droplet size consistent with acceptable efficacy. Formation of very small droplets may
be minimized by appropriate nozzle selection, by orienting nozzles away from the air stream as much
as possible, and by avoiding excessive spray boom pressure. For groundboom and aerial
applications, use medium or coarser spray nozzles according to ASAE 572 definition for standard
nozzles or a volume mean diameter (VMD) of 300 microns or greater for spinning atomizer nozzles.
2. Make aerial or ground applications when the wind velocity favors on-target product deposition. Apply
only when the wind speed is less than or equal to 10 mph. For all non-aerial applications, Wind cpoed
must be measured adjacent to the application site on the upwind side, immediately "prior0 to
application. 'tl' 1'" (t ,
3. Do not make aerial or ground applications into areas of temperature inversions. clnversio'i\scijre
characterized by stable air and increasing temperatures with increasing distance >aBcve theLgrpnnd.
Mist or fog may indicate the presence of an inversion in humid areas. Where permissible byjo'cal
regulations, the applicator may detect the presence of an inversion by prpclypirlg smoke, and
observing a smoke layer near the ground surface. *"' c
4. Low humidity and high temperatures increase the evaporation rate of spray droplets and therefore"t'he
likelihood of increased spray drift. Avoid spraying during conditions of low humidity and/oph.igh
temperatures. < >L <
5. All aerial and ground application equipment must be properly maintained and calibrated using
appropriate carriers.
6. For groundboom applications, apply with nozzle height no more than 4 feet above the ground or crop

( ( %.canopy.
7. For airblast applications, turn off outward-pointing nozzles at row ends and when spraying the outer
two rows. To minimize spray loss over the top in orchard applications, spray must be directed into
the canopy.
"8: ^For aerial applications, release Ispray at the lowest'heightconsistentwittTefficacy'and flight safety. If
the application includes an aquatic buffer zone, do not release spray at a height greater than 10 feet
above the ground or crop canop*y.
9. For aerial applications, the spray boom should be mounted on the aircraft so as to minimize drift
caused by wing tip vortices. The minimum practical boom length should be used and must not
exceed 75% of the wingspan of)90% of rotor blade diameter. Use upwind swath displacement.
' INFORMATION
Dimethoate 400 is useful for control of certain pests of certain fruit crops, nuts, vegetables, and field
crops. Dimethoate 400 may be applied by ground sprayers or by airplanes, mixing the Dimethoate 400 in
water to form an emulsion spray solution. To make the spray solution, half fill the spray tank with water,
agitate, add the proper amount of Dimethoate 400 and then fill the spray tank with water while still
agitating. Continue to agitate during use.
When applying with ground sprayers, calibrate so as to apply the specified amount of Dimethoate 400 in
not less than 3 gallons of water per acre unless directed otherwise. Airplanes must spray the specified
amount of Dimethoate 400 in 3 to 10 gallons of water per acre unless directed otherwise. Always use
sufficient water for adequate coverage of the crop foliage. The dosages given under DIRECTIONS FOR
USE are the amounts of Dimethoate 400 to be applied per acre treated per application. Repeat
application as necessary, unless otherwise directed in DIRECTIONS FOR USE. Where a dosage range
is given, use the lower rate in small or young plants or with light insect infestations; use the higher rate on
large or more mature plants or with heavy insect infestations. The hazards and precautions for handling
Dimethoate 400 in this container are equally applicable to it after dilution with water for spray application.
APPLICATION THROUGH IRRIGATION SYSTEMS
Apply this product only through sprinkler, including center pivot, lateral move, end tow, side (wheel) roll,
traveler, big gun, solid set, or hand move irrigation systems. Do not apply this product through any other
type of irrigation system.
Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from non-uniform
distribution of treated water.
If you should have questions about calibration, you should contact State Extension Service specialists,
equipment manufacturers, or other experts.
Do not connect an irrigation system (including greenhouse systems) used for pesticide application to a
public water system unless the pesticide label-prescribed safety devices for public water systems are in
place. . <:
A person knowledgeable of the chemigation system and responsible for its opefa'tfoVi, or under the
supervision of the responsible person, shall shut the system down and make necessaVy adjystrrieiits
should the need arise. ''c^c. <tc
v t
In a clean supply tank, mix the recommended amount of this product for acreage tqb&cuvered and the
needed quantity of water.
This product should not be tank-mixed with other pesticides, surfactants, or fertilizers unless prior use lias
shown the combination non-injurious under your conditions of use. «.<'<•
Follow precautionary statements and directions for all tank-mixed products.

On all crops, use sufficient gallonage of water to obtain thorough and uniform coverage, but not cause
runoff or excessive leaching. This will vary depending on equipment, pest problem and stage of growth.
Application of more or less than optimal quantity of water may result in decreased chemical performance,
crop injury, or illegal pesticide residues.
Meter this product into the irrigation water uniformly during the period of operation. Do not overlap
application. Follow recommended label rates, application timing, and other directions and precautions for
crop being treated.
Continuous mild agitation of pesticide mixture may-tie needed to assure a uniform application, particularly
if the supply tank requires a number of hours to empty.
a
SYSTEMS CONNECTED TO PUBLIC WATER SOURCES
Great care must be taken and properly maintained equipment must be used when connecting
chemigation systems to public water supplies. The following information is provided for users who have
diligently considered all other application and water supply options before electing to make such a
connection.
Public water system means a system for the provision to the public of piped water for human
consumption if such a system has at least 15 service connections or regularly serves an average of at
least 25 individuals daily at least 60 days out of the year. Chemigation systems connected to public water
systems must contain a functional reduced-pressure zone, backflow preventer, or the functional
equivalent in the water supply line upstream from the point of pesticide introduction. As an option to the
RPZ, the water from the public water system should be discharged into a reservoir tank prior to pesticide
introduction. There shall be a complete physical break (air gap) between the outlet end of the fill pipe and
the top or overflow rim of the reservoir tank of at least twice the inside diameter of the fill pipe.
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 contain a functional, normally closed, solenoid-operated valve
located on the intake 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 automatically or manually
shut down.
The system must contain functional interlocking controls to automatically shut off the pesticide injection
pump when the water pump motor stops, or in cases where there is no water pump, 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 anri/catp£ble
of being fitted with a system interlock. c c c c

Use of dimethoate is prohibited during any time of day in any given orchard
from when that orchard has 10% open blooms until such time as there has
been at least 75% petal fall on the north side of the trees. Applications of
dimethoate shall be limited to4hatperiod-of4ime-between one (-1-) hoijr after
sunset to three (3) hours before sunrise when any one of the following
conditions prevail: 1) Before the onset of petal fall, the orchard to be treated
has open blooms present and these open blooms represent less than 10% of
the total anticipated blooms in the orchard. 2) After the initiation of pe,tal fall
there are less than 25% of open blooms remaining in the orchard to be treated.
3) It is between the calendar dates of February 15 and May 1st.
All applications of dimethoate on citrus must be documented on Form 1080
written either by a pest control advisor, farm owner or farm manager £s is
normally required for custom applications of pesticides, except that private
applicators may omit the "Pesticide Application Report" section. The description
of the status of bloom of the orchard to be treated as it was at the time of the

ORNAMENTALS
For Use On Ornamental Plants Grown In Nurseries Only. Not For Residential Use.
Dimethoate 400 is effective in controlling many sucking, piercing, and chewing insects, including aphids,
thrips, leafminers, scales, leafhoppers, and mites, that attack valuable ornamental plantings. For proper
timing of treatments for the control of specific pests on ornamental plants, consult local agricultural
authorities. Apply sprays uniformly and thoroughly to foliage, except as otherwise directed, when insects
or their damage is first observed. Repeat applications as needed. Do not overdose or overspray. Use
only on the ornamental plants listed below.
IMPORTANT - Do not use on ornamental plants grown in greenhouses, Christmas tree and conifer
plantations, landscapes, interiorscapes and residential, public, recreational, commercial, industrial, and
institutional establishments. When making soil injections, use a low pressure soil injection device.
Always wear a full face shield, rubber gloves, long-sleeved shirt, and rubber apron. DO NOT inject into
