GENERAL INFORMATION

PYRIFLUQUINAZON insecticide is a suspension concentrate containing 1.80 lbs. of active ingredient per

gallon. This product is a contact insecticide used for the control of various insects. PYRIFLUQUINAZON

insecticide should be used in a program with other products to provide season long protection. Apply as 

a spray as directed in the “Application Directions” section of this label.

RESISTANCE MANAGEMENT

PYRIFLUQUINAZON insecticide contains pyrifluquinazon, which has not been classified by IRAC. 

Repeated use of the same chemistry has been shown to result in the buildup of resistant strains of 

insects. Rotate the use of PYRIFLUQUINAZON insecticide with alternate mode of action insecticides.

Resistance management strategies recommend that you DO NOT apply rates lower than recommended 

on the label. For best results, do not make more applications of PYRIFLUQUINAZON insecticide than 

permitted on the label in a single crop cycle. Contact your local extension specialist or certified crop 

advisor for additional resistance management or IPM recommendations. Also, for more information about 

Insect Resistant Management (IRM), visit the Insecticide Resistance Action Committee (IRAC) on the 

web at http://www.irac-online.org. 

MIXING DIRECTIONS

Shake well before using. Read and follow all label directions for each tank mix product prior to any tank 

mixing with PYRIFLUQUINAZON insecticide. This product can be mixed with other registered pesticides.

The most restrictive use directions and precautions must be followed. 

PYRIFLUQUINAZON Insecticide Alone: Begin with clean equipment. Fill spray tank with 3⁄4 of the 

amount of water needed for the intended application and then turn on agitation. Pour recommended 

amount of product on the surface of water in the spray tank. Add the balance of the water to the spray 

tank with agitation running. Keep agitation running during filling and spraying operations. If spraying 

must be stopped before emptying the sprayer, resume agitation before spraying the remainder of the 

load.

PYRIFLUQUINAZON Insecticide Tank Mixtures: Begin with clean equipment. Fill spray tank with 3⁄4 of 

the amount of water needed for the intended application and then turn on agitation. If using a buffering

agent, add after filling the tank with 3⁄4 amount of water. Add the recommended amount of tankmix 

products in the following order while maintaining agitation: 

1) products in water-soluble packets

2) wettable powders

3) water-disperable granulars and/or soluble powders 

4) flowable liquids

5) emulsifiable concentrates 

6) adjuvants and/or oils

7) remaining amount of water to achieve the desired level

PYRIFLUQUINAZON Insecticide Tank Mixtures With Products in Water-Soluble Packaging: Follow 

all use directions as listed above under PYRIFLUQUINAZON Insecticide Alone with the following 

exception: add the desired number of water-soluble bags to the tank (if allowed by their label 

instructions) at the same time the PYRIFLUQUINAZON insecticide is added. Note: If using products in 

water soluble packaging, do not tank mix with products that contain boron, chromium, or other 

micronutrients.

PYRIFLUQUINAZON insecticide is physically and biologically compatible with many registered 

pesticides, fertilizers or micronutrients. Contact your supplier for advice when considering mixing 

PYRIFLUQUINAZON insecticide with other pesticides, fertilizers or micronutrients. If you have no 

experience with the combination you are considering, you should conduct a test to determine physical 

compatibility. To determine physical compatibility, add the recommended proportions of each chemical 

with the same proportion of water, as will be present in the chemical supply tank, into a suitable container, 

mix thoroughly and allow to stand for five minutes. If the combination remains mixed, or can be readily 

re-mixed, the mixture is considered physically compatible.

APPLICATION DIRECTIONS

USE LIMITATIONS AND PRECAUTIONS

Indoor Greenhouse Use on Ornamental Crops 

▪ Do not apply this product through any type of irrigation system.

▪ Do not apply this product as a smoke or aerosol.

▪ Do not harvest cut flowers for 48 hours after spraying.

▪ Keep compost in sheltered compost area.

▪ Do not apply this product to plants used for food or animal feed. 

▪ Do not apply to fruit trees and vines that will bear harvestable fruit within 12 months.

Indoor Greenhouse Use on Ornamental Crops 

PYRIFLUQUINAZON insecticide is recommended for use in indoor greenhouses on several ornamental 

plants. The use directions of this product are based on the results of product testing programs on a wide 

variety of ornamental plants. However, it is impossible to test this product on all species and cultivars. The 

phytotoxicity of PYRIFLUQUINAZON insecticide has been assessed on a wide variety of common 

ornamental plants with no phytotoxic effects. However, not all plant species and their varieties and 

cultivars have been tested with possible tankmix combinations, sequential pesticide treatments, and 

adjuvants and surfactants. Local conditions also can influence crop tolerance and may not match those 

under which testing has been conducted. Therefore, before using PYRIFLUQUINAZON insecticide, test 

the product on a sample of the crop to be treated to ensure that a phytotoxic response will not occur as a 

result of applications. 

PYRIFLUQUINAZON insecticide works primarily through contact and translaminar activity, so good spray 

coverage is necessary for control of listed insects on the label. Applications should be made immediately 

after the spray solution is prepared. Under severe insect pressure, use the maximum rates and the 

shorter spray interval as specified on the label. Dense foliage or excessive growth will often prevent 

adequate coverage; adjust spray volumes accordingly. Mix with sufficient water and apply as a foliar 

spray to obtain uniform coverage. Treat plants when pests are immature or at a susceptible stage and 

populations are building, before crop damage occurs.
D-120 061812-1

PYRIFLUQUINAZON 20% SC

Page 5 of 7

Applications may be made with high or low volume spray equipment that provides thorough coverage of 

the plant. Apply with properly calibrated spray equipment. A wetting agent or other spray adjuvant, 

approved for use on the crop, may be added to spray solutions according to the manufacturer’s use 

instructions to achieve optimum control.

CONTROLLING PESTICIDE RUNOFF

Do not allow pesticide spray solution to run off outside of the application area. Do not use in greenhouses that discharge irrigation runoff to surface water drains. If applied in an area with a non-permeable 

floor and a floor drainage system, excess application spray or irrigation runoff must be collected and 

subjected to secondary wastewater treatment.
