BASIC USE INFORMATION 
QRD 146 is a broad spectrum, preventative product for the control or suppression of many important plant diseases. 
Apply QRD 146 as a foliar spray alone, in alternating spray programs or in tank mixes with other registered crop 
protection products. [Apply QRD 146 as a soil drench alone or in tank mixes with other registered crop protection 
products.] When conditions are conducive to heavy disease pressure, use QRD 146 in a rotational program with other 
registered fungicides. Apply QRD 146 with spray equipment commonly used for making ground [or aerial] applications 
and sprinkler/irrigation systems commonly used for chemigation. Heavy rainfall or irrigation shortly after application 
may require retreatment. QRD 146 can be used for organic production. 
 
[OPTIONAL STATEMENT: QRD 146 is most effectively used in a preventive disease management program. For 
improved performance, use QRD 146 in a tank-mix or rotational program with other registered fungicides. When using 
QRD 146 alone for the first time, use a rate of 2 lbs. QRD 146 per acre. Increase the application rate and/or decrease 
spray intervals of QRD 146 according to the application instructions depending upon disease pressure . [To enhance 
performance, consider adding a surfactant, known to be safe to the target crop, to the spray tank to improve penetration 
and coverage of above-ground portions of the plant.]] 
 
INTEGRATED PEST MANAGEMENT (IPM) 
Integrate QRD 146 into an overall disease and pest management strategy whenever fungicide use is necessary. Follow 
practices known to reduce disease development. Consult local agricultural authorities for specific IPM strategies 
developed for your crop(s) and location. 
 
Be sure use of this product conforms to resistance management strategies, which may include rotating and/or tank -
mixing with other products with different modes of action. 
 
USE RATE DETERMINATION 
Carefully read and follow all label directions, use rates and restrictions. Application of QRD 146 prior to or in the early 
stages of disease development provides the best control or suppression of the targeted plant disease . Use the stated 
maximum label rates and shorter spray intervals for conditions conducive to threatening or rapid disease development. 
[For proper application, determine the number of acres to be treated, the label use rate and select appropriate gallonage 
to give good canopy penetration and coverage of plant parts to be protected.] Prepare only the amount of spray solution 
required to treat the measured acreage. Accurate spray [alternate: chemigation] equipment calibration is essential prior 
to use. 
 
PREHARVEST INTERVAL 
QRD 146 can be applied up to and including the day of harvest. 
 
APPLICATION INSTRUCTIONS 
GENERAL: Avoiding spray drift at the application site is the responsibility of the applicator. Th e interaction of many 
equipment and weather-related factors determines the potential for spray drift. The applicator and the grower/treatment 
coordinator are responsible for considering all of these factors when making decisions. Where states have more 
stringent regulations, they should be observed. Note: This section is a dvisory in nature and does not supersede the 
mandatory label requirements. 
 
GROUND: Be sure to maintain agitation during mixing and application to assure uniform product suspension. 
Thorough coverage of all foliage [alternate statement for soil uses: [and] soil surfaces] is essential for effective disease 
control. QRD 146 can be applied in commonly used ground equipment, hose-end, pressurized, greenhouse and hand-
held sprayers. To achieve good coverage , use proper spray pressure, gallonage per acre, noz zles, nozzle spacing 
and ground speed. Consult spray nozzle and accessory catalogues for specific information on proper equipment 
calibration. 
 
AERIAL: This product can be applied by aerial application. Refer to the Aerial Drift Reduction Advisory Information 
section of this label for general directions and precautions. Use the application rate indicated for the appropriate crop 
in sufficient water to a chieve thorough coverage, typically between 3 – 20 gallons of water per acre depending upon 
the crop. Three gallons of water per acre is the minimum.

7 
 
CHEMIGATION: This product can be applied through sprinkler (center pivot, lateral move, end tow, side (wheel) roll, 
traveler, solid set, and hand move) or drip type irrigation systems. Refer to the Chemigation Directions for Use 
section of this label for general directions and precautions. Use the application rate indicated for the appropriate crop 
as specified in the Application Rate tables of this label. 
 
MIXING INSTRUCTIONS 
MIXING: QRD 146 must be diluted with water. Partially fill the spray tank with clean water and begin agitation. Add 
the specified amount of QRD 146 to the tank. Finish filling the tank to the necessary volume to obtain the proper spray 
concentration. It is critical that the spray solution be agita ted during mixing and application to assure a uniform 
suspension. Do not allow spray mixture to stand overnight or for prolonged periods. [Optional Statement: Maintain a 
spray solution pH between 4.5 and 8.5.] 
 
QRD 146 may be tank-mixed with other registered pesticides to enhance plant disease control. This product cannot be 
mixed with any product with a prohibition against such mixing. When tank -mixing QRD 146 with other registered 
pesticides, always read and follow all use directions, restriction s, and precautions of both QRD 146 and the tank-mix 
partner(s). Use of the resulting tank mix must be in accordance with the more restrictive label limitations and 
precautions. Do not exceed label dosage rates. 
 
COMPATIBILITY: Do not combine QRD 146 in the spray tank with pesticides, surfactants or fertilizers if there has been 
no previous experience or use of the combination to show it is physically compatible, effective and non-injurious under 
your use conditions. 
 
QRD 146 is compatible with many c ommonly used pesticides, fertilizers, adjuvants and surfactants but has not been 
fully evaluated with all of these. To ensure compatibility of tank-mix combinations, evaluate them prior to use as follows: 
Using a suitable container, add proportional amounts of product to water. Add wettable powders first, followed by water 
dispersible granules, then by liquid flowables and lastly, emulsifiable concentrates. Mix thoroughly and let stand for at 
least five minutes. If the combination stays mixed or can be remixed, it is physically compatible. Test the combination 
on a small portion of the crop to be treated to ensure that a phytotoxic response will not occur as a result of application. 
[OPTIONAL STATEMENT: Do not use with penetrant-type adjuvants.] 
 
ADDITIVES: QRD 146 is compatible with a wide range of additives. Since the product is primarily a protectant, thorough 
coverage of all above -ground plant parts is required for effective product performance. To improve plant surface 
coverage, add a nonphytotoxic adjuvant to spray tank. 
 
CHEMIGATION DIRECTIONS FOR USE 
General Requirements:

solid set or hand move) or drip type irrigation systems. Do not apply this product through any other type of irrigation 
system. 
2) Crop injury or lack of effectiveness can result from non-uniform distribution of treated water. 
3) Ensure that the irrigation system used is properly calibrated and if you have questions, call the State Extension 
Service specialists, the equipment manufacturer or other experts. 
4) 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. 
5) A person knowledgeable of the chemigation system and responsible for its operation, or under the supervision of 
the responsible person, shall shut the system down and make any necessary adjustments should the need arise. 
 
 Requirements for Chemigation Systems Connected to Public Water Systems: 
1) Public water supply means a system for the provision to the public of pipe d water for human consumption if such 
system has at least 15 service connections or regularly serves an average of 25 individuals daily at least 60 days 
throughout the year. 
2) Chemigation systems connected to the public water systems must contain a functi onal, reduced-pressure zone 
(RPZ), backflow preventer or the functional equivalent in the water supply 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 of the overflow rim of the reservoir tank of at least twice the inside diameter of the fill pipe. 
3) The pesticide injection pipeline must contain a functional, automatic, quick closing check valve to prevent the flow 
of fluid back towards the injection pump.

8 
 
4) 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. 
5) 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. 
6) 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 filled 
with a system interlock. 
7) Do not apply when wind speed favors drift beyond the area intended for treatment. 
8) Remove scale, pesticide residues, and other foreign matter from the chemical supply tank and entire injector 
system. Flush with clean water. Failure to provide a c lean tank, void of scale or residues may cause product to 
lose effectiveness or strength. 
9) Do not combine QRD 146 with pesticides, surfactants or fertilizers for application through chemigation equipment

from the supply tank when the irrigation system is either automatically or manually shut down. 
4) The system must 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 functional 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 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. 
7) Do not apply when wind speed favors drift beyond the area intended for treatment. 
8) Remove scale, pesticide residues, and other foreign matter from the chemical supply tank and entire injector 
system. Flush with clean water. Failure to provide a clea n tank, void of scale or residues may cause product to 
lose effectiveness or strength. 
9) Do not combine QRD 146 with pesticides, surfactants or fertilizers for application through chemigation equipment 
unless prior experience has shown the combination physi cally compatible, effective and non -injurious under

AERIAL DRIFT REDUCTION ADVISORY INFORMATION 
 
General: Avoiding spray drift at the application site is the responsibility of the applicator. Th e interaction of many 
equipment and weather-related factors determine s the potential for spray drift. The applicator and the grower are 
responsible for considering all these factors when making decisions. Where states have more stringent regulations, 
they should be observed. 
INFORMATION ON DROPLET SIZE: The most effective way to reduce drift potential is to apply large droplets. The 
best drift management strategy is to apply the largest droplets that provide sufficient coverage and control. Applying 
larger droplets reduces drift potential, but will not prevent drift if applications are made improperly, or under unfavorable 
environmental conditions (see Wind, Temperature and Humidity, and Temperature Inversions). 
 
CONTROLLING DROPLET SIZE: Volume - Use high flow rate nozzles to apply the highest practical spray volume. 
Nozzles with higher rated flows produce larger droplets. Pressure - Do not exceed the nozzle manufacturer’s 
recommended pressures. For many nozzle types, lower pressure produces larger droplets. When high flow rates are 
needed, use higher flow rate nozzles instead of increasing pressure. Number of Nozzles - Use the minimum number 
of nozzles that provide uniform coverage. Nozzle Orientation - Orienting nozzles so that the spray is released parallel 
to the airstream produces larger droplets than other or ientations and is the recommended practice. Significant 
deflection from horizontal will reduce droplet size and increase drift potential. Nozzle Type - Use a nozzle type that is 
designed for the intended application. With most nozzle types, narrower spr ay angles produce larger droplets. 
Consider using low -drift nozzles. Solid stream nozzles oriented straight back produce the largest droplets and the 
lowest drift. 
 
BOOM WIDTH: For aerial applications, the boom width must not exceed 75% of the wingspan o r 90% of the rotary 
blade. Use upwind swath displacement and apply only when wind speed is 3 – 10 mph as measured by an 
anemometer. Use medium or coarser spray according to ASAE 572 definition for standard nozzles or VMD for spinning 
atomizer nozzles. If application includes a no-spray zone, do not release spray at a height greater than 10 feet above 
the ground or the crop canopy. 
 
APPLICATION HEIGHT: Do not make application at a height greater than 10 feet above the top of the largest plants 
unless a gr eater height is required for aircraft safety. Making applications at the lowest height that is safe reduces 
exposure of droplets to evaporation and wind. 
SWATH ADJUSTMENT : When applications are made with a crosswind, the swath will be displaced downward. 
Therefore, on the up and downwind edges of the field, the applicator must compensate for this displacement by 
adjusting the path of the aircraft upwind. Swath adjustment distance should increase, with increasing drift potential 
(higher wind, smaller drops, etc.). 
 
WIND: Drift potential is lowest between wind speeds of 3 - 10 mph. However, many factors, including droplet size and 
equipment type determine drift potential at any given speed. Application should be avoided below 3 mph due to variable 
wind direction and high inversion potential. NOTE: Local terrain can influence wind patterns. Every applicator should 
be familiar with local wind patterns and how they affect spray drift. 
 
TEMPERATURE AND HUMIDITY : When making applications in low relative humidity, set up equipment to produce 
larger droplets to compensate for e vaporation. Droplet evaporation is most severe when conditions are both hot and 
dry. 
 
TEMPERATURE INVERSIONS : Do not apply during a temperature inversion because drift potential is high. 
Temperature inversions restrict vertical air mixing, which causes small, suspended droplets to remain in a concentrated 
cloud. This cloud can move in unpredictable directions due to the light variable winds common during inversions. 
Temperature inversions are characterized by increasing temperatures with altitud e and are common on nights with 
limited cloud cover and light to no wind. They begin to form as the sun sets and often continue into the morning. Their 
presence can be indicated by ground fog; however, if fog is not present, inversions can also be identi fied by the 
movement of smoke from a ground source or an aircraft smoke generator. Smoke that layers and moves laterally in a 
concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly 
dissipates indicates good vertical air mixing. 
 
SENSITIVE AREAS: The pesticide should only be applied when the potential for drift to adjacent sensitive areas (e.g. 
residential areas, bodies of water, known habitat for threatened or endangered species, non -target crops) is minimal 
(e.g. when wind is blowing away from the sensitive areas). Do not allow spray to drift from the application site and 
contact people, structures people occupy at any time and the associated property, parks and recreation areas, non -
target crops, aquatic and wetland areas, woodlands, pastures, rangelands, or animals.

open, untreated blossoms when conditions 
favoring disease development are likely to occur. 
For maximum effectiveness, use QRD 146 prior to 
and as close as possible to Fire Blight infection 
events. During periods of rapid bloom 
development and frequent infection periods, use 
2- to 7 -day spray intervals. After petal fall, 
continue applications on a 7 -day interval while 
environmental conditions favor disease 
development. 
Apply in sufficient water to provide full coverage. 
For improved performance, QRD 146 may be 
used in a rotational program with antibiotics 
registered for Fire Blight control such as but not 
limited to oxytetracycline or streptomycin. 
Proper orchard cult ural practices are essential to 
eliminate Fire Blight -infected tissue from the 
orchard to assure good performance of any crop 
protection product. Care must be taken to remove 
and destroy dead and diseased wood from the 
orchard prior to and during the growing season. 
Use of QRD 146 alone has not been shown to 
affect fruit finish. Use caution when selecting 
spray adjuvants. Select only those adjuvants 
which through prior experience do not affect fruit 
finish when combined with QRD 146.

FOR USE AS A SOIL TREATMENT ON SELECT AGRICULTURAL FIELD CROPS 
QRD 146 has a 0-Day PreHarvest Interval for all crops contained on this label. 
Under moderate to severe disease pressure, for improved performance, increase rates and reduce spray intervals as 
stated or use QRD 146 in a tank mix or rotational program with other registered fungicides. 
 
QRD 146 is a broad spectrum biofungicide for the prevention, suppression and control of soil borne diseases on a wide 
range of fruits and vegetables as well as cotton. QRD 146 enhances germination and plant growth by suppressing 
diseases caused by Rhizoctonia, Pythium, Fusarium, Verticillium, and Phytophthora. 
 
APPLICATION INSTRUCTIONS: 
Soil Treatment At Planting: 
Use at planting, seeding, or transplant. Mix 0.25 lb. to 3 lb.[alternate: 4 - 48 oz] of QRD 146 in appropriate amount of 
water per acre. Use the stated higher application rates under conditions of heavy disease pressure. Apply finished 
mixture at a rate to thoroughly soak the growing media through the root zone (1 pint finished mixture / sq. ft for each 3 
inches of soil depth) as a drench or directed spray using hand held, mechanical or motorized spray equipment, or as a 
chemigation drench or directed spray using applicable sprinkler or drip irrigation systems. QRD 146 can be mixed with 
chemical fungicides registered for soil applications. 
 
Soil Treatment Through Irrigation: Use at any stage of plant growth. Mix 0.25 lb. to 3 lb.[alternate: 4 - 48 oz] of QRD 
146 in appropriate amount of water per acre. Use the stated higher application rates under conditions of heavy disease 
pressure. Optimal performance is obtained with preventative treatments repeated every 21 to 28 days throughout the 
growing cycle. QRD 146 can be mixed with chemical fungicides registered for soil applications. 
 
In-Furrow Applications: 
For in-furrow applications, apply QRD 146 as an in-furrow spray in 5 - 15 gallons of water at planting. Mount the spray 
nozzle so the spray is directed in the furrow just before the seeds are covered. Use the stated higher rates when the 
weather conditions are expected to be conducive for disease development, if the field has a history of disease problems, 
of if minimum/low till programs are in place.

BASIC USE INFORMATION 
QRD 146 is a preventative product for the suppression of Green Mold in mushroom production. Mix QRD 146 with 
mushroom spawn grains, mushroom growing supplement or apply QRD 146 as a drench alone to the surface of 
mushroom beds, in alternating drench programs or in tank mixes with other registered mushroom production protection 
products. When used as a drench , apply QRD 146 with spray equipment commonly used for making ground 
applications and sprinkler/irrigation systems commonly used for chemigation in mushroom p roduction. QRD 146 can 
be used for organic production. 
 
INTEGRATED PEST MANAGEMENT (IPM) 
Integrate QRD 146 into an overall disease and pest management strategy whenever fungicide use is necessary. Follow 
practices known to reduce disease development. Consult local agricultural authorities for specific IPM strategies 
developed for your crop(s) and location. 
 
Be sure use of this product conforms to resistance management strategies, which may include rotating and/or tank -
mixing with other products with different modes of action. 
 
USE RATE DETERMINATION 
For all treatments, carefully read and follow all label directions, use rates and restrictions. For treatment of mushroom 
spawn grains and growing supplement , use the stated maximum label rat es when heavy disease development is 
anticipated. For drench applications , application of QRD 146 prior to or in the early stages of disease development 
provides the best suppression of Green Mold. Use the stated maximum label rates for conditions conduc ive to rapid 
disease development or when disease development is anticipated. For proper application, determine the number of 
square feet of bed surface to be treated and the label use rate. For drench applications , prepare only the amount of 
spray solution required to treat the measured square feet of bed surface. Accurate spray equipment calibration is 
essential prior to use. 
 
PREHARVEST INTERVAL 
QRD 146 can be applied up to and including the day of harvest. 
 
APPLICATION INSTRUCTIONS 
 
GROUND: For treatment of mushroom spawn grains and growing supplement , be sure to completely mix QRD 146 
with gypsum, limestone or chalk according to Application Instructions and Dosages Table prior to mixing with mushroom 
spawn grains or growing supplement. Thorough mixture of the treated mushroom growing substrate is essential for 
effective disease suppression. 
 
For drench applications , be sure to maintain agitation during mixing and application to assure uniform product 
suspension. Thorough coverage of beds is essential for effective disease suppression. QRD 146 can be applied with

56 
 
commonly used ground equipment: hose -end, pressurized, greenhouse and hand -held sprayers. To achieve good 
coverage, use proper spray pressure, gallonage per square feet of bed surface, nozzles, nozzle spacing and ground 
speed. Consult spray nozzle and accessory catalogues for specific information on proper equipment calibration. 
 
CHEMIGATION: This product can be applied through sprinkler (solid set and hand move) or drip type irrigation systems. 
Refer to the Chemigation Directions for Use section of this label for general directions and precautions. Use the drench 
application rate as specified in the Application Instructions and Dosages Table of this label. 
 
MIXING INSTRUCTIONS 
MIXING: For treatment of mushroom spawn grains and growing supplement, be sure to completely mix QRD 146 with 
gypsum, limestone or chalk according to Application Instructions and Dosages Table prior to mixing with mushroom 
spawn grains or growing supplement. Thorough mixture of the treated mushroom growing substrate is essential for 
effective disease suppression. 
 
For drench applications, QRD 146 must be diluted with water. Partially fill the spray tank with clean water and begin 
agitation. Add the required amount of QRD 146 to the tank. Finish filling the tank to the necessary volume to obtain 
the proper spray concentration. It is critical that the spray solution be agitated during mixing and application to assure 
a uniform suspension. Do not allow spray mixture to stand overnight or for prolonged periods. Maintain a spray solution 
pH between 4.5 and 8.5. 
 
QRD 146 may be tank -mixed with other registered pesticides to enhance mushroom disease control. This product 
cannot be mixed with any product with a prohibition against such mixing. When tank -mixing QRD 146 with any other 
registered pesticides, always read and follow all use directions, restrictions, and precautions of both QRD 146 and the 
tank mix partner(s). Use of the resulting tank mix must be in accordance with the more restrictive label limitations and 
precautions. Do not exceed label dosage rates. 
 
COMPATIBILITY: Do not combine QRD 146 in the spray tank with pesticides, surfactants or fertilizers if there has been 
no previous experience or use of the combination to show it is physically compatible, effective and non-injurious under 
your use conditions. 
 
QRD 146 is compatible with many commonly used pesticides, fertilizers, adjuvants and surfactants but has not been 
fully evaluated with all of these. To ensure compatibility of tank-mix combinations, evaluate them prior to use as follows: 
Using a suitable container, add proportional amounts of product to water. Add wettable powders first, followed by water 
dispersible granules, then by liquid flowables and lastly, emulsifiable concentrates. Mix thoroughly and let stand for at 
least five minutes. If the combination stays mixed or can be remixed, it is physically compatible. Test the combination 
on a small portion of the crop to be treated to ensure that a phytotoxic response will not occur as a result of application. 
 
ADDITIVES: QRD 146 is compatible with a wide range of additives. Since the product is primarily a protectant, thorough 
coverage of the mushroom bed surface is required for effective product performance when used as a drench. When 
used to treat mushroom spawn grains and growing supplement , thorough mixing of the mushroom growing substrate 
is required for effective product performance. 
 
CHEMIGATION DIRECTIONS FOR USE 
General Requirements: 
1) Apply this product only through sprinkler (solid set and hand move) or drip type irrigation systems. Do not apply 
this product through any other type of irrigation system. 
2) Crop injury or lack of effectiveness can result from non-uniform distribution of treated water. 
3) Ensure that the irrigation system used is properly calibrated and if you have questions, c all the State Extension 
Service specialists, the equipment manufacturer or other experts. 
4) 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. 
5) A person knowledgeable of the chemigation system and responsible for its operation, or under the supervision of 
the responsible person, shall shut the system down and make any necessary adjustments should the need arise. 
 
 
 
 
Requirements for Chemigation Systems Connected to Public Water Systems:

57 
 
1) Public water supply 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 25 individuals daily at least 60 days 
throughout the year. 
2) Chemigation systems connected to the public water systems must contain a functional, reduced -pressure zone 
(RPZ), backflow preventer or the function al equivalent in the water supply 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 phy sical break (air gap) between the outlet end of 
the fill pipe and the top of the overflow rim of the reservoir tank of at least twice the inside diameter of the fill pipe. 
3) The pesticide injection pipeline must contain a functional, automatic, quick closing check valve to prevent the flow 
of fluid back towards the injection pump. 
4) 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. 
5) 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. 
6) 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 filled 
with a system interlock. 
7) Do not apply when wind speed favors drift beyond the area intended for treatment 
8) Remove scale, pesticide residues, and other foreign matter from the chemical supply tank and entire injector 
system. Flush with clean water. Failure to provide a clean tank, void of scale or residues may cause product to 
lose effectiveness or strength. 
9) Do not combine QRD 146 with pesticides, surfactants or fertilizers for application through chemigation equipment 
unless prior experience has shown the combination physically compatible, effective and non -injurious under 
conditions of use. QRD 146 has not been fully evaluated for compatibility with all adjuvants or surfactants. Conduct 
a spray compatibility test if mixture with adjuvants or surfactants is planned. 
10) Maintain agitation in the pesticide supply tank. 
11) Apply QRD 146 during the last half of the water application. 
12) Dilute QRD 146 in enough water to be able to draw through system for the last half of the water application. 
 
Sprinkler Chemigation Requirements: 
1) 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. 
2) The pesticide injection pipeline must contain a functional, 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 automatically or manually shut down. 
4) The system must 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 functional 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 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. 
7) Do not apply when wind speed favors drift beyond the area intended for treatment. 
8) Remove scale, pesticide residues, and other foreign matter from the chemical supply tan k and entire injector 
system. Flush with clean water. Failure to provide a clean tank, void of scale or residues may cause product to 
lose effectiveness or strength. 
9) Do not combine QRD 146 with pesticides, surfactants or fertilizers for application through chemigation equipment 
unless prior experience has shown the combination physically compatible, effective and non -injurious under 
conditions of use. QRD 146 has not been fully evaluated for compatibility with all adjuvants or surfactants. 
Conduct a spray compatibility test if mixture with adjuvants or surfactants is planned.

when the water pump motor stops. 
5) 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 where pesticide distribution is adversely affected. 
6) 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. 
7) Remove scale, pesticide residues, and other foreign matter from the chemical supply tank and entire injector 
system. Flush with clean water. Failure to provide a clean tank, void of scale or residues may cause product to 
lose effectiveness or strength. 
8) Do not combine QRD 146 with pesticides, surfactants or fertilizers for application through chemigation equipment 
unless prior experience has shown the combination physically compatible, effective and non -injurious under 
conditions of use. QRD 146 has not been fully evaluated for compatibility with all adjuvants or surfactants. Conduct 
a spray compatibility test if mixture with adjuvants or surfactants is planned. 
9) Maintain agitation in the pesticide supply tank. 
10) Apply QRD 146 during the last half of the water application. 
11) Dilute QRD 146 in enough water to be able to draw through system for the last half of the water application.
