Overture 35WP Insecticide — Pyridalyl Wettable Powder Thrips Control 1lb

Control Resistant Western Flower Thrips at Every Life Stage — Without Harming Beneficials

Western flower thrips is one of the most economically damaging pests in greenhouse, ornamental, and specialty crop production — and one of the hardest to control once a resistant population establishes. Overture 35WP Insecticide delivers Pyridalyl, an insecticide with a novel mode of action (IRAC Group 25) distinct from spinosyns, organophosphates, pyrethroids, and all other registered chemistry. This means Overture is active against thrips populations that have developed resistance to other major insecticide classes, giving growers a productive new tool when existing programs stop performing.

Pyridalyl is particularly effective because it controls thrips at all life stages — eggs, larvae, pupae, and adults — rather than targeting a single life stage as many other insecticides do. This all-stage activity collapses populations more completely in fewer applications, which is critical in high-pressure greenhouse environments where thrips complete multiple generations per season and populations rebuild quickly between spray intervals. Importantly, Overture 35WP is safe on most beneficial insects, preserving the natural enemy populations that support IPM programs and reduce pressure from secondary pests simultaneously.

In addition to thrips control, Overture 35WP also manages Budworm and Cabbage Looper larvae, extending its value to operations dealing with mixed lepidopteran and thrips pressure. Applied at 8oz per 100 gallons, it is compatible with standard spray equipment used in both greenhouse and field production systems.

Key Features & Benefits

• Novel Mode of Action — IRAC Group 25 (Pyridalyl) — Provides control of thrips populations resistant to spinosyns, organophosphates, pyrethroids, and other registered chemistries, making it one of the most valuable resistance-management tools available to growers with chronic thrips pressure.
• All Life Stage Control — Eggs to Adults — Pyridalyl is active against thrips eggs, larvae, pupae, and adults, delivering more complete population suppression than products targeting a single life stage and reducing the rate at which populations rebuild between applications.
• Safe on Most Beneficial Insects — Unlike broad-spectrum insecticides, Overture 35WP preserves beneficial insect populations — including predatory mites and parasitic wasps — that are essential components of IPM programs in greenhouse and high-value crop production.
• Targets Western Flower Thrips Specifically — Frankliniella occidentalis (western flower thrips), widely considered the most economically damaging and resistance-prone thrips species in North American production systems, is a primary target for Overture 35WP.
• Controls Budworm and Cabbage Looper Larvae — Extends control beyond thrips to include lepidopteran larvae, making Overture useful in operations where mixed pest complexes include both thrips and caterpillar species simultaneously.
• Wettable Powder Format — Stable and Easy to Handle — The 35WP dry formulation has a longer shelf life than emulsifiable concentrates, ships and stores safely at ambient temperatures, and suspends readily in water for uniform application at 8oz per 100 gallons.

Who Should Use Overture 35WP Insecticide

Overture 35WP is the right choice for greenhouse growers, ornamental producers, vegetable and specialty crop growers, and IPM practitioners managing thrips pressure — especially where western flower thrips populations have demonstrated resistance to spinosad, pyrethroid, or other existing chemistry. It is also well-suited for integrated programs where preserving beneficial insect populations is a core management objective. Operations cycling through IRAC groups for resistance management will find Overture 35WP's Group 25 mode of action a valuable rotation partner with Groups 5 (spinosyns), 3 (pyrethroids), and 28 (diamides).

Pests Controlled

Overture 35WP controls western flower thrips and other thrips species at all life stages (eggs, larvae, pupae, adults), Budworm larvae, and Cabbage Looper larvae. Apply at 8oz per 100 gallons with standard spray equipment. REI is 12 hours. Active ingredient is Pyridalyl (IRAC Group 25). Not registered for use in Alaska.

Frequently Asked Questions

How does Pyridalyl control thrips differently from spinosad or pyrethroid-based products?

Pyridalyl belongs to IRAC Group 25, a novel class with a mode of action distinct from all other registered insecticide groups. Spinosad (Group 5) acts on nicotinic acetylcholine receptors and GABA-gated chloride channels; pyrethroids (Group 3) target voltage-gated sodium channels; and many thrips populations have developed resistance to one or both of these chemistries. Pyridalyl appears to disrupt cell membrane integrity through a different mechanism, providing efficacy against populations that no longer respond to conventional chemistry.

Why is all life stage control important for thrips management?

Thrips complete their life cycle rapidly — as fast as two weeks at greenhouse temperatures — and products that control only adults or only larvae allow surviving life stages to repopulate treated areas within days. Pyridalyl's activity across eggs, larvae, pupae, and adults means each application removes more of the population more completely, extending the interval before re-treatment is needed and reducing the total number of applications required per season.

What beneficial insects are safe when using Overture 35WP?

Overture 35WP has demonstrated safety on many commercially released beneficial insects, including predatory mites (Phytoseiidae), minute pirate bugs (Orius spp.), and several parasitic wasp species commonly used in greenhouse IPM programs. Growers using biological control agents should consult compatibility data specific to their beneficials before applying any insecticide, as selectivity can vary by species and exposure route.

Can Overture 35WP be used in greenhouse production?

Yes. Overture 35WP is used in greenhouse and indoor production settings where western flower thrips is a primary pest challenge. Its selectivity for beneficial insects is particularly valuable in enclosed greenhouse environments where introduced biological controls are part of the integrated program. Confirm labeled use sites on the current label for your specific crop and facility type before application.

Is Overture 35WP compatible with other insecticides in a rotation program?

Overture 35WP is most valuable as a rotation partner with other IRAC groups in a resistance management program. Because its Group 25 mode of action is unique, it can be alternated with spinosyns (Group 5), pyrethroids (Group 3), diamides (Group 28), and organophosphates (Group 1B) to prevent any single mechanism from driving resistance in thrips or lepidopteran pest populations. Tank-mix compatibility should be confirmed with a jar test before large-scale use.
