GENERAL INFORMATION

Mattch Bioinsecticide belongs to a new class of increased residual, high potency biological insecticides based on Mycogen's CellCap® Encapsulation System of Bacillus thuringiensis (Bt) toxins. The biotoxins in Mattch are effective against several major caterpillar pests, but are low in toxicity to beneficial insects and mammals.

• Mode of Action: Mattch contains two powerful 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 a rapid halt to feeding within hours, 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 improves its 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, which are encapsulated separately in Pseudomonas fluorescens bacterial cells. Cry1A(c) of Bacillus thuringiensis variety kurstaki was selected based on its superior activity on tobacco budworm, cotton bollworm and cabbage looper. Cry1C of B. thuringiensis variety aizawai was selected based on its superior activity on armyworms and cabbage looper. Once the toxins are formed inside the bacterial cells during the fermentation process, the cells are killed and then blended in a constant ratio that is optimized for control of the targeted pests.

STEPS FOR SUCCESSFUL RESULTS

1. Use Mattch in an integrated pest management program in cotton to control the Heliothis pest complex and to manage resistance to synthetic pyrethroids and other synthetic insecticides.
2. Mattch is most effective when eaten by newly hatched or 1st and 2nd instar larvae. Scout for eggs and newly hatched larvae on terminals and squares to ensure proper application timing.
3. Apply Mattch as a stand alone or tank mixed with ovicidal rates of conventional insecticides during the early season. Apply Mattch mixed with larvicides during mid and late season.
4. Treat as needed based on intensity of the infestation and weather conditions. Scout fields 3-5 days after application to determine time of subsequent applications.
5. Complete coverage of the cotton plant's foliage where larvae are feeding is essential for good control. Application volumes should be sufficient to ensure good coverage.

USE GUIDELINES

Rates:

Tobacco Budworm and Cotton Bollworm Control

Early Season/    Apply Mattch at 1.5 - 3.0 pints per acre, tank mixed     
Pre-Bloom Stage  with recommended ovicidal rates of synthetic             
                 insecticides.                                            
                 Apply Mattch at 2 - 6 pints per acre stand alone, or     
                 when used in combination with companion products         
                 directed at non-caterpillar pests, or with plant growth  
                 regulators.                                              
Mid or Late      Apply Mattch at 1.5 - 3 pints per acre tank mixed with   
Season           recommended larvicidal rates of conventional             
Applications     insecticides.                                            

• Apply Mattch at 4 - 6 pints per acre stand alone, or 2 - 4 pints per acre when tank mixed with a recommended conventional insecticide to control loopers or armyworms in cotton.
• Rates of Mattch should be adjusted as pest pressure and crop foliage increase.

Application:

• For aerial application using water as the carrier, apply the recommended rate of Mattch in 2-5 gallons of spray per acre. Foliar coverage will increase with higher volumes of spray.
• For ULV application, apply the recommended rate of Mattch plus emulsified oil and companion insecticide. Mix spray components in the following order: emulsified oil, emulsifiable concentrate pesticides, liquid flowable pesticides, Mattch.
• For ground application, apply the recommended rate of Mattch on a broadcast basis in 5-20 gallons of spray per acre. Adjust the rate of Mattch and spray volumes per acre for banded applications.
• The addition of an emulsified oil to spray solutions containing Mattch for ground and aerial applications is recommended to improve deposition on cotton foliage.

Tank Mixing: Comply with the most restrictive label instructions when tank mixing Mattch with other pesticides.

Always read and carefully follow all product labels.
