General Information


PYLON is a member of the class of miticides known as Pyrroles. PYLON has good contact and excellent stomach activity. PYLON uncouples oxidative phosphorylation, preventing conversion of ADP to ATP, and the mite or insect dies from the inability to generate its own energy.

Limitations, Restrictions, and Exceptions



- Apply specified dosage using sufficient water to obtain uniform and complete coverage of foliage.

- PYLON is not ovicidal. PYLON should be used in combination with a registered ovicidal miticide when moderate to high populations of eggs are present at time of application.

- When mite populations are high in several areas of the greenhouse or throughout several crops within one greenhouse structure, apply PYLON at 5.2 fl oz/ 100 gals (0.08 lb ai/ 100 gals) and make a sequential application at 5 –7 days after the first application. PYLON is not systemic and does not translocate throughout the plant. However, PYLON moves rapidly from the top to the underside of a leaf - to control spider mites, larvae and nymphs emerging from eggs. PYLON will be diluted in rapidly expanding, new foliage as compared to the concentration in the leaf surface at the time of application. For this reason, it is important to make two consecutive applications of PYLON within 5 –7 days when under high mite pressure.

- Low to moderate populations of spider mites can be controlled for 14 – 21 days with one PYLON application at 2.6 – 5.2 fl. oz.

- Make only one sequential application at 5 to 7- day interval when necessary. See section on RESISTANCE MANAGEMENT for additional instructions.


To minimize the risk of injury to ornamentals, make applications prior to blooming or avoid blooms where possible. Apply in the coolest times of the day.

PYLON has been evaluated for phytotoxicity on a wide range of ornamental plants; however, it has not been possible to evaluate all commercially important species, varieties and cultivars within the species listed below. Local conditions can also influence crop safety and may not match those under which PYLON was tested.

All tank mixes should be evaluated for phytotoxicity prior to application due to additive effects of surfactants and wetting agents contained in both formulations.

Do not tank mix with products that contain a label prohibition against tank mixing. It is unlawful to tank mix this product if the tank mix will be used outdoors.

No unacceptable injury has occurred to the following greenhouse ornamental plants when treated with PYLON according to label instructions: African daisy, Chrysanthemum, Grape Ivy, Petunia, African violet, Cock’s comb, Impatiens, Ranunculus, Ageratum, Croton, Lily oriental, Snapdragon, Alex Ivy, Fuschia, Lisianthus, Verbena, Aster, Gardenia, Marigold, Vinca, Azalea, Gazania, Miniature rose, Begonia, Geranium, Needlepoint Ivy, California Ivy, Gerbera daisy, Pansy.

Apply PYLON to a small area (8-12 plants) and evaluate for 3 – 5 days before attempting a large-scale spray to make certain that no phytotoxicity occurs.

PHYTOTOXICITY IS LIKELY TO OCCUR to some varieties of: carnations, dianthus, kalanchoe, poinsettia, roses, salvia and zinnia and applications to these species will be made at grower risk.

NOT RECOMMENDED: Additions of crop oils, surfactants, and fertilizers or other tank additives have been shown to increase the likelihood of foliage injury and are not recommended with the product.

REMARKS: Use suffient spray volume to ensure thorough coverage.

For Spider mite: May require two (2) applications on a 5 - 7 day spray schedule at the 5.2 fl. oz./100 gal. (0.08 lb. ai/100 gal.) under high mite pressure. Refer to the section on RESISTANCE MANAGEMENT.


Treatment may not be effective if tolerant strains develop. To reduce the potential for developing pest resistance to the product, alternate with insecticides and miticides from different classes of chemicals with different modes of action.

Use one of the following resistance management strategies:

1. DO NOT APPLY PYLON more than two (2) times consecutively or a total of three (3) times during a growing cycle (Start to finish for one ornamental crop.)

— and —

2. DO NOT APPLY PYLON to consecutive crops in a greenhouse structure.

— or —

3. PYLON SHOULD BE applied in combination with other effective miticides/insecticides with a different mode of action when used in a subsequent crop in the same greenhouse structure.
