USE INFORMATION 
PHITICIDE is a systemic product containing mono and dibasic phosphites. The phosphonic ion is effective in controlling 
downy mildew, brown rot, foot rot and other diseases caused by Phytophthora, Pythium and other related fungi by 
activating the plant’s natural resistance mechanisms. When used in a complete Integrated Pest Management (IPM) 
disease control program with good cultural practices, this product will provide control of the listed diseases. To achieve 
the best results in disease control spraying, initiate before signs or symptoms of the disease are present or when the 
disease first appears or environmental conditions are conducive to disease development. 
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 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 State or Tribal agency 
responsible for pesticide regulation. 
AGRICULTURAL USE REQUIREMENTS 
Use this product only in accordance with its labeling and with the Worker Protections Standard (WPS), 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,

NON-AGRICULTURAL USE REQUIREMENTS 
The requirements in this box apply to uses of this product that are not within the scope of the WPS for agricultural 
pesticides, 40 CFR part 170. The WPS applies when this product is used to produce agricultural plants on farms, 
forests, nurseries or greenhouses. Do not enter treated area until spray has dried.
MIXING AND APPLICATIONS INSTRUCTIONS 
Apply this product with properly calibrated ground sprayer, aerial equipment or sprinkler system. Always apply this 
product in sufficient water for thorough coverage. Fill the mix tank to one-half capacity before adding the required 
amount of this product. Add the remaining amount of water while continuously agitating the mixture. Do not apply when 
conditions favor drift from target area or wind speed is greater than 10 mph. 
Mixture is to be applied to plant foliage, unless directed otherwise in the application rate table. Good agitation must be 
provided during the entire application period. Spray equipment must be cleaned thoroughly before and after 
applications. 
Ground Application 
Apply the specified rate of this product in sufficient water for thorough coverage of foliage or as stated for optimum 
disease control. 
Aerial Application 
Apply the specified rate of this product in a minimum of 3 gallons of water per acre unless otherwise stated. 
PRECAUTIONS FOR CHEMIGATION APPLICATIONS 
Apply this product only through center pivot, lateral move , end tow, side (wheel) roll, hand move, drip, microjet and 
solid set 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 have questions about calibration, you should contact State Extension Service specialists, 
equipment manufacturers or other experts. 
Do not connect a chemigation 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 respons ible for its operation, or under the supervision of the 
responsible person, shall shut the system down and make necessary adjustments should the need arise. 
Public 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 regular 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 form 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 flow 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. 
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 and capable of being fitted with a system 
interlock. 
Sprinkler and Drip Trickle Irrigation Systems 
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 back flow. 
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 
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. 
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 when 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 favors drift beyond the area intended for treatment. 
The pesticide supply tank should be equipped with a means for continuous agitation either by recirculation or a 
mechanical agitator. Charge the supply tank with the appropriate amount of water and add the pesticide slowly followed 
by any sticker-spreaders, insecticides, nutrients, etc. Observe all cautions and limitations on the labels of all products 
used in the mixtures. For fixed position irrigation systems such as center pivot, big gun, etc, apply the pesticide towards 
the end of the irrigation period. Exact timing will depend on the desired pesticide application rate and calibration of the 
system. For moving systems, apply the pesticide continuously. In all cases, provide thorough coverage of the crop. 
CROP USE PRECAUTIONS 
Mixing this product with certain surfactants, foliar fertilizers, or other pesticides can cause crop injury. If you do not have
prior experience using this product as a solo treatment or in a tank mixture, you must determine crop sensitivity to a 
particular combination by spraying a small area of foliage and fruit. Evaluate for 3 to 7 days for adverse effects. 
To assure compatibility of this product with other products, pour the products into a small container of water in the 
correct proportions: After thorough mixing, let stand for 5 minutes. If the combination remains mixed, or can be re-
mixed readily, the mixture is compatible. 
Mixing of this product with other products has been known to increase the salt content and the potential for fruit burn. 
Environmental factors that enhance burn potential include applying product during the following conditions: 
1) At temperatures above 90°F, 
2) Shortly after a rain event, 
3) During color break of the fruit. 
Apply with extreme caution when these conditions exist. Determine crop sensitivity to these factors by spraying small 
areas of foliage and fruit. Evaluate for 3 to 7 days for adverse effects.

Pyracantha, Sweet Birch, Sweet Gum, White Pine, White c edar and Willow in landscapes, forestry, golf courses and 
parks.
For control of Phytophthora and Pythium diseases such as stem and canker blight (Sudden Oak Death, 
Phytophthora ramorum), Beech decline and general tree decline syndrome: Make applications before disease 
development and in conjunction with good cultural management practices. Use higher application rates when disease 
pressure is severe. Do not apply to trees that are in a state of dormancy or under heat or moisture stress. Do not exceed 
indicated application rates or apply more frequently than stated on the label or tree injury may occur. 
Injection Applications for Phytophthora, Phytophthora ramorum and Pythium spp.: Inject 11 fluid ounces per 21 
fluid ounces of water or 1/2 teaspoonful per teaspoonful of water in the following manner: Drill holes 3/16 inch (5 mm) 
into live sapwood (depth dependent upon age of tree) with a downward angle into trunk uniformly around the tree 
circumference using a slow drill. Do not inject into areas of obvious canker, decay or mechanical injury that appear on 
the tree trunk. Calculate the amount of product required by measuring the trees using one of the following three 
methods, and use the highest calculated number of injections. 1) One injection per square yard of canopy; 2) One 
injection per yard of diameter of canopy measured at the drip-line; 3) One injection per 6 inches of trunk circumference 
measured 4 feet above soil level. Make injections with applicators that maintain positive pressure differential such as 
ChemJet
®, Sidewinder®, Ag-murph Gun®, Marley® Injector, or hydraulic applicator type equipment that forces solution 
into the sapwood of the tree. 
Injection Application for Suppression of Gnomonia platani (Sycamore anthracnose): Apply 3.5 pints plus 8.5 
pints of water plus 2.5% v/v (3.2 fl. ozs./gal.) of organosilicone based surfactant. Inject 20 mL of the prepared solution 
per tree. Drill holes 3/16 inch (5 mm) in diameter and 1 inch (25 mm) to 2 inches (50 mm) deep with slight downward 
angle in trunk. Place syringes in the main trunk of the tree and space evenly around the circumference of the trunk. 
May be used with equipment such as ChemJet
®, Ag-murf Gun ® or positive pressure hydraulic tree injection. Treat 
trees that are at least 10 inches diameter at breast height. 
Basal Bark Spray for Phytophthora, Phytophthora ramorum and Pythium spp.: Apply 62.4 fluid ounces plus 62.4 
fluid ounces of water with 3.2 fluid ounces of Pentra-Bark ™ bark penetrating surfactant. Apply uniformly to 6 to 9 feet 
of trunk circumference. Spray from the top down to ground level from either the first branch or as high as possible 
without exposing applicator to drift. Use as a preventative or curative application. Apply solution with hydraulic sprayer, 
handheld pump sprayer, backpack sprayer, hose-end applicators with backflow preventers, and other similar 
applicators. 
Basal Bark Spray for Suppression of Apple Black spot and Scab ( Venturia inaequalis): Apply 51 fluid ounces 
plus 74 fluid ounces of water plus 2.5% v/v (3.2 fl. ozs./gal.) of organosilicone surfactant. Apply in early Spring at 
budswell or silver tip growth stage. Spray a mixture of this product and organosilicone surfactant around the complete 
circumference of the tree trunk until saturation/runoff. Spray from ground level up to 5 feet above the soil line including 
the base of the first scaffolding limbs, if present. Treatment generally provides protection for 8 to 12 weeks depending 
on pathogen levels. Higher disease pressure will shorten the length of control. Various types of application equipment 
may be used such as hydraulic sprayers, handles pump-type sprayers, backpack sprayers, hose-end applicators with 
backflow prevention devices and other similar application equipment. 
For Suppression of Fire Blight: Apply 2.5 pints per 100 gallons of water, as a foliar spray, to thoroughly wet the 
foliage. Begin applications at the pre-bloom stage and continue until the end of bloom period at 7 day intervals. For 
Hawthorne, Ornamental pear and Pyracantha, mix 2.5 pints in 100 gallons of water and spray to wet using no more 
than 400 gallons of water per acre. Because this product functions as a preventative application, apply the first spray 
treatment before blooms appear. Repeat application once every 7 days until bloom period ends. Do not apply more 
than once every 7 days. Always use a thorough disease sanitation program to reduce the spread of diseases to 
uninfected plants. 
TURF 
This product is a systemic fungicide for use on turfgrass such as those found on golf courses, sod farms and other turf 
areas to control Pythium diseases and yellow tuft. Begin preventative application with a properly calibrated sprayer 
when conditions first favor disease development. Repeat at the specified intervals. DO NOT mow or water treated 
areas until sprays have dried.
