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 green­
houses, and handlers of agricultural pesticides. It contains requirements for training, decontamination, notification 
and emergency assistance. It also contains specific instructions and exceptions pertaining to the statements on this 
label about Personal Protective Equipment (PPE), and restricted-entry interval. The requirements in this box apply to 
uses of this product that are covered by the Worker Protection Standard. 
Do not enter or allow worker entry into treated areas during the restricted-entry interval (REI) of 48 hours. 
PPE required for early entry to treated areas that is permitted under the Worker Protection Standard and that in­
volves contact with anything that has been treated, such as plants, soil, or water, is: A) Coveralls; B) Chemical­
resistant gloves such as barrier laminate, butyl rubber, nitrile rubber or viton; C) Chemical-resistant footwear plus 
socks; D) Protective eyewear; E) Chemical-resistant headgear for overhead exposure. 
DIRECTIONS FOR APPLICATION 
This product is intended for use in conventional hydraulic sprayers, ground applicators or aerial sprayers. Do not apply when 
weather conditions favor drift of spray from treated areas. Repeat applications as necessary unless otherwise specified. 
Consult your state experiment station or state extension service for proper timing of applications. 
DIGON 400 has systemic and contact activity against a broad spectrum of piercing, sucking and chewing insects; however, 
it may not control certain organophosphate resistant species. 
COMPATIBILITY: DIGON 400 is compatible in spray tank mixes with most insecticides, miticides and fungicides, provided 
they are not alkaline in reaction. Field experience indicates that DIGON 400 has been satisfactorily mixed with Sevin', 
Diazinon, Guthion', Kelthane', parathion, captan, zineb and thiram. Because uniform dispensability and spray ability may be 
influenced by pesticide combinations used, it is recommended that compatibility be determined before adding pesticides to 
the spray tank. The addition of R-11'" at recommended rates will usually eliminate any incompatibility noted. 
::lR PROPER MIXING SPRAYTANK SHOULD BE AT LEASTTHREE·QUARTERS FILLED WITH WATER BEFORE ADD· 
ING DIGON 400. MECHANICAL AGITATION OR RECIRCULATION THROUGH PUMP BYPASS TO TANK IS USUALLY 
SUFFICIENT FOR MAINTAINING A GOOD DISPERSION, 
Spray tank mixes of OIGON 400 with alkaline insecticides and fungicides should be applied promptly. 
Tank mixing must be done in accordance with the more (most) restrictive of label limitations and precautions for all products 
to be mixed. No label dosage rates should be exceeded. This product cannot be mixed with any product containing a label 
prohibiting such mixing. 
ODOR: DIMETHOATE formulations may produce a distinctive odor during the spray operation, but under norrlal conditions 
this odor does not persist. 
Aerial Applications: Apply at least one gallon of finished spray per acre. Apply at least 5 gallons finishej spra! per acre in 
California. 
Automatic flagging devices should be used whenever feasible. 
If human lIaggers are employed, they must wear the protective clothing and respirator specified or. this label. 
Ground Applications: Use water for dilution and apply at least 5 gallons of finished spray ~£r &cre. 
WILBUR-ELLIS recommends the use of a drift retardant agent such as BIVERT'" when applying this pesticide by air or 
ground.

DIRECTIONS FOR USE 
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. 
Do not apply this product through any irrigation system unless the CHEMIGATION section of this label is followed. 
Chemigation: APPLYTHIS PRODUCT ONLYTHROUGH SPRINKLER, INCLUDING CENTER PIVOT, LATERAL MOVE, END 
TOW, SIDE (WHEEL) ROLL, TRAVELER, BIG GUN, SOLID SET, OR HAND MOVE; FLOOD (BASIN); FURROW; BORDER; 
OR DRIP (TRICKLE) IRRIGATION SYSTEM(S). DO NOT APPLY THIS PRODUCTTHROUGH ANY OTHER TYPE OF IRRIGA­
TION SYSTEMS. 
Crop injury, lack of effectiveness, or illegal pesticide residues in the crop can result from nonuniform distribution of treated 
water. 
If you have questions about calibration, you should contact State Extension Service specialists, equipment manufacturers or 
other experts. 
DO NOT connect an irrigation system (including greenhouse system) 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 operation, or under the supervision of the res pon­
. sible person shall shut the system down and make necessary adjustments should the need arise. 
Mix in a clean supply tank the recommended amount of this product for acreage to be covered, and needed quantity of water. 
This product should not be tank-mixed with other pesticides, surfactants or fertilizers, unless prior use has shown the combi­
nation non-injurious under your conditions of use. Follow precautionary statements and directions for all tank-mix 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 crop 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 recom­
mended label rates, application timing, and other directions and precautions for crop being treated. Continuous mild agitation of 
pesticide mixture may be needed to assure uniform application, particularly if the supply tank requires a number of hours to 
empty. 
CHEMIGATION SYSTEMS CONNECTEDTO PUBLIC WATER SYSTEMS: 
Note: WILBUR-ELLIS COMPANY does not encourage 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. 
1 
t'ublic water system means a system for the provision to the public of piped water for human consumption if such 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, back flow preventer 
(RPZ) 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 the fluid 
back toward the injection pump. 
The pesticide injection pipeline must contain a functional, normally closed, solenoid-operated valve locateu on th" intake side 
of the injection pump and connected to the system interlock to prevent fluid from being withdr,wr 'r':lm the su::>Ply 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 inj€'ctlon purrr '¥~en the water 
pump motor stops, or in cases where there is no water pump, when the water pressure decrea333 to the POlr.t wh3re pesticide 
distribution is adversely affected. 
Systems must use a metering pump, such as a positive displacement injection pump (e.g., diaphragm ;JJ:Cp) effectively 
designed and constructed of materials that are compatible with pesticides and capable of being fitted with a syshJm interlock. 
DO NOT apply when wind speed favors drift beyond the area intended for treatment.

DIGON 400 is generally effective in controlling APHIDS, BALSAM TWIG APHID, THRIPS, LEAF MINERS, SCALES LEAF­
HOPPERS and MITES. Make adequate spray when pests appear or when damage is first observed. Do not overdose or 
overspray. For proper timing of treatments for the control of specific pests on ornamental plants, consult your state agricultural 
experiment station or state agricultural extension service. Do not use on ornamental plants that are not listed on this label 
unless personal experience has shown DIGON 400 to be safe. A small test area should always be sprayed first before general use. 
Do not use on any ornamental stock plants grown as a source of propagation material, such as cuttings, layers, root stocks or 
scions for grafting or budding. Do not use in spray mixtures containing oil. Do not use on plants growing in greenhouses.
