For Control of Caterpillar Pests in Vegetables

Including Armyworms, Diamondback Moths, Loopers,

and Heliothis/Helicoverpa Species

Mattch Bioinsecticide belongs to a new class of increased residual, high potency, biological insecticides utilizing Mycogen's CellCap® Encapsulation System. The biotoxins in Mattch are effective against a broad range of major caterpillar pests, but are low in toxicity to beneficial insects and mammals.

• Mode of Action: Mattch contains two delta endotoxins which are potent insect stomach poisons and must be eaten by the target insect to be effective. Once eaten the biotoxins disrupt the larva's digestive system, resulting in starvation and death one to five days later. Mattch is most effective against 1st and 2nd instar caterpillar larvae.
• CellCap Encapsulation System: Mattch utilizes the CellCap Encapsulation System, a patented process which allows for an easy handling formulation and improves field performance and shelf life. Conventional Bt's degrade rapidly on the leaf surface due to adverse effects of heat, sunlight and other environmental factors. This degradation renders the biotoxin ineffective against feeding larvae. Mattch uses biological microcapsules to protect the biotoxins from environmental degradation. As a result Mattch provides greater foliar persistence than traditional Bt products. Mattch delivers more consistent, longer lasting control of caterpillar pests.
• Toxins: Mattch contains two delta endotoxins of Bacillus thuringiensis. Cry1A(c) of

B. thuringiensis variety kurstaki was selected based on its superior activity on diamondback moth, cabbage looper, tobacco budworm and tomato fruitworm. Cry1C of B. thuringiensis variety aizawai was selected based on its superior activity on armyworms, cabbage looper and diamondback moth larvae which in some areas are resistant to B. thuringiensis variety kurstaki.

USE GUIDELINES

• Stand alone: Use Mattch at 2.0 quarts per acre for most stand alone applications. When diamondback moth is the primary pest, a lower rate of 1.5 quarts per acre normally provides excellent control.
• Tank mix: In most situations, Mattch should be applied at 1.0 quart per acre when tank mixed with other pesticides which are also directed at the same lepidopteran pest(s).
• Uniform and complete coverage of the foliage where larvae are feeding is essential to good control. Application water volume should be sufficient to ensure good coverage, a minimum of 20 GPA is recommended. For aerial application, use a minimum of 5 gallons of total spray volume per acre.
• The addition of an appropriately labeled spreader-sticker is recommended to improve coverage and deposition on crop foliage.

When tank mixing Mattch with other insecticides, comply with all label instructions of all products which are included.

STEPS FOR SUCCESSFUL RESULTS

1. Scout for eggs and apply Mattch when newly hatched larvae are present. Mattch is most effective when applications are targeted at newly hatched, 1st and 2nd instar larvae and before the insect can penetrate inside the plant's protective foliage, stems, or fruit.
2. Scout fields 3 to 5 days after application to determine the effectiveness of the application, and to assess the need for subsequent applications.
3. Retreat as needed to control reinfesting or increasing pest populations. More than one application per week may be necessary when larval populations are high.
4. Reapply Mattch if rain occurs within six hours after treatment.

Always read and carefully follow all product labels.
