GENERAL INFORMATION 
. -
Diazinon 40W is an wettable powder which should be mixed with sufficient water to assure thorough 
coverage unless otherwise noted in the Directions for Use. Best control is obtained when application 
is made at first sign of pest. Application should be repeated onJy as directed to maintain control. 
Since Diazinon 40W is a wettable powder formulation, constant agitation is-necessary during appli­
cation. 
-- --
To avoid spray drift, do not apply under windy conditions. Avoid spray overlap, since crop or plant 
injury may result. 
Do not use onfood crops grown in greenhouses.

CEPTIBILITY TO VERY SMALL DOSES OF ANYCHOLlNESTERASt INHIBITOR. -
When handling Diazinon 40W, do not rob eyes or mouth with bands. If you feel sick in any way, 
STOP work and get help right away. See Practical Treatment section oIthis label. 
CHEMIGATION 
APPLICATION THROUGH At'\{ IRRIGATIONSYST'EM-CCHEMtgAtfON)- CRANBER~­
RIESONLY: 
Diazinon 40W may be applied alone or in combination with other pesticides registered for applica­
tion through sprinkler irrigation systems to cranberries. To insure compatibility, pour the products 
into a small container of water in the correct proportions. After thorough mixing, let stand for five 
minutes. If the combination remains mixed, or can be remixed readily, the mixture is compatible. 
Do not apply this product through any type of irri~tion system to other crops. For chemigation, 
apply this product to cranberries onJy through sprinkler irrigation systems. Do not apply this product 
to cranberries 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 have questions about calibration, you should contact State 
Extension Service specialists, equipment rD.anufacturers, or other experts.- . -- .c. - . 
Do·not connect the irrigation system used for pesticide application to apublic water system unlessthe 
pesticide label-prescribed safety devices for public water systems are in place. A person knowledge­
able of the chemigation system and responsible for its operation, or under the supervision of the 
responsible person, shall shut the system down and ~ake necessary adjustments if the need arises.

Chemigation System Connected toPuhlic Water Systems 
. -
1. Public water system means a system for the provision to the public of piped water for human 
consumption if such system has at leasU5 service connections or regularly serves an average of at 
least 25 individuals daily at least 60 days out of the year. 
6 
2. Chernigation systems connected to public water systems must contain a functional, reduced­
pressure zone, backflow preventer (RPZ) or the functional equivalent in the water supply line up­
stream 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. 
) Sprinkler Chemigation 
1. The system must contain a functional check valve, a vacuum relief valve, and low pressure drain 
appropriately located on the irrigation pipeline to prevent water source contamination from backflow. 
2. The pesticide injection pipeline must contain a functioual, automatic, quick-closing check valve to __ 
prevent the flow of fluid back toward the injection pump. 
3. The pesticide injection pipeline must also 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 auto­
matically or manually shut down. 
4. The system mnst contain functional interlocking controls to automatically shut off the pesticide 
injection pump when the water pump motor stops. 
5. The irrigation line or water pump must include a functioual pressure switch which will stop the 
water pump motor when the water pressure decreases to the point where pesticide distribution is 
adversely affected. 
6. Systems must use a metering purnp, such as a positive displacement injection pump (e.g., dia­
phragm pump) effectively designed and constructed of materials that are compatible with pesticides 
and capable of being fitted v,ith a system interlock . • 
7. Do not apply when wind speed favors drift beyond the area intended for treatment. 
Operating Instructions 
1. Determine the acreage to be treated by the sprinkler system. 
2. MeaSure the appropriate amount ofDiazinon 40W needed to treat the acrea8.e..t<J.!J.e_treated.

per acre. 
3. Add the pre-measured Diazinon 40W to the chemigation system supply tank and dilute with 
wztterifneeded. Proper agitation is needed ifDiazinon 40W is tank mixed with other pesticides 
registered for sprinkler chemigation application to cranberries. 
7 
4. Start the irrigation system and bring the system up to full pressure, making certain that all sprinkler 
heads are functioning properly. 
5. Engage the chemigation injection or venturi system to add the diazinon to the irrigation lines. 
6. Continue to run irrigation system for a few minutes after supply tank is empty to allow material in 
the irrigation lines to reach the sprinkler heads further from the chemigation injection point. 
FRUIT AND NUT CROPS 
REI - 24 hours 
Diazinon 40W may be applied using ground or aerial application equipment as specified in the 
follo",ing Table. This Table indicates the minimum amount of water that can be used for various 
methods of application. The rate ofDiazinon 40W for aerial spray or concentrated spray applied by 
ground equipment is based on a dilute full cover spray applied to fruit or nut trees with conventional 
ground equipment at a rate of300-400 gals. of water per acre. The specific amount of product to be 
used appears under separate directions for use for each crop. (Note: "Ibs. " or "lbs. of product" in the 
direction means pounds of this product, not pounds of active ingredient). If the Rate calls for 1 lb. of 
Diazinon 40'V per 100 gallons of water, this amounts to 3'1.-4 Ibs. of product per acre when applied 
to fruit trees at the usual dilute ground spray volumes of300-400 gals. of water per acre. In no case 
should the amount of product used per acre exceed the maximum amount per acre per application 
that is specified in the directions for use for individual crops .

Note: (1) Ifseed has not been treated with a fungicide, use an EPA-registered fungicide combination 
with Diaiiinon 40W at rates indicated on the fungicide package. Failure to use a fungicide may result 
in injury to the seed. (2) If the seed treatment increases the friction between seeds sufficiently to 
reduce the rate of delivery through the plant, Y> oz. of graphite per bushel seed should be added as a 
drill lubricant. Adjust the planter to give the required rate of seed delivery with the treated seed. (3) 
Treated seed must not be used for or mixed with food or animal feed or processed for oil.
