GENERAL INFORMATION

MVP®II Bioinsecticide belongs to a new class of Bacillus thuringiensis based insecticides utilizing Mycogen's CellCap® Encapsulation System, possessing increased residual and higher potency. The specially selected biotoxin in MVP II makes it the most effective Bt product against tobacco budworm (Heliothis virescens) and cotton bollworm (Heliocoverpa zea). The CellCap system bioencapsulates and protects the biotoxin so that the residual activity is several days longer than conventional Bt products.

• Optimized Toxin: MVP II contains a specially selected toxin of Bacillus thuringiensis variety kurstaki (Cry1Ac) which is the most potent toxin against tobacco budworm and cotton bollworm. MVP also controls a wide range of other lepidopteran pests in cotton including loopers and armyworms.
• Greater Persistence: MVP II 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 which renders the biotoxin ineffective against feeding larvae. MVP II uses biological microcapsules to protect the biotoxins from environmental degradation. CellCap products including MVP II are more rainfast than conventional Bt insecticides. As a result MVP II provides greater foliar persistence than traditional Bt products which results in more consistent control of caterpillar pests.
• Consistency: Conventional Bt insecticides perform unpredictably due to short residual activity. The increased residual activity of MVP II enables it to consistently outperform other Bt products from application to application and from field to field.

STEPS FOR SUCCESSFUL RESULTS

1. Use MVP II 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. MVP II 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 MVP II as a stand alone or tank mixed with ovicidal rates of conventional insecticides during the early season. Apply MVP II mixed with larvicides during mid and late season.
4. Treat every 5-10 days based on intensity of the infestation and weather conditions. Scout fields 3-5 days after application to 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 MVP II at .75-1.5 pints per acre, tank mixed with  
Pre-Bloom Stage  recommended ovicidal rates of synthetic insecticides.    
                 Apply MVP II at 1-3 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 MVP II at .75-1.5 pints per acre tank mixed with   
Season           recommended larvicidal rates of carbamates,              
Applications     organophosphates or synthetic pyrethroids.               

• Apply MVP II at 2-3 pints per acre stand alone, or 1-2 pints per acre when tank mixed with a recommended conventional insecticide to control loopers or armyworms in cotton.
• Rates of MVP II should be adjusted as pest pressure and crop foliage increase.

Application:

• For aerial application using water as the carrier, apply the recommended rate of MVP II 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 MVP II plus emulsified oil and companion insecticide. Mix spray components in the following order: emulsified oil, emulsifiable concentrate pesticides, liquid flowable pesticides, MVP II.
• For ground application, apply the recommended rate of MVP II on a broadcast basis in 5-20 gallons of spray per acre. Adjust the rate of MVP II and spray volumes per acre for banded applications.
• The addition of an emulsified oil to spray solutions containing MVP II 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 MVP II with other pesticides.
