(PACIFIC NORTHWEST) TREE FRUITS

GENERAL INFORMATION

MVP®II Bioinsecticide provides selective and effective control of caterpillar pests in pome and stone fruit. MVP II belongs to a new class of bioinsecticides based on Mycogen's CellCap® Encapsulation System with increased residual activity and higher potency. MVP II is effective against several worm pests of tree crops, but is of low toxicity to beneficial insects and mammals.

Mode of Action: MVP II contains a specially selected delta endotoxin of Bacillus thuringiensis var. kurstaki encapsulated in killed Pseudomonas fluorescens bacteria. The delta endotoxin is a potent insect stomach poison and must be eaten by the target worm to be effective. Once eaten the biotoxin disrupts the worm's digestive system, resulting in starvation and death one to five days later. MVP II is most effective against small feeding caterpillars in tree fruits.

CellCap Encapsulation System: MVP II utilizes the CellCap Encapsulation System, a patented process which improves its field performance and shelf life. Conventional Bts 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. MVP II uses biological microcapsules to protect the biotoxins from environmental degradation. As a result MVP II remains active longer on the leaf and provides more consistent and effective pest control.

USE GUIDELINES:

• MVP II is most effective when applications are targeted at newly hatched caterpillars before they penetrate the foliage or fruit or before leafrolling occurs.
• Use MVP II at 1.5 - 2.0 quarts per acre. (Refer to reverse side for recommended rate ranges under each crop group.)
• Uniform and complete coverage of the foliage where larvae are feeding is essential for good control. Application water volume should be sufficient to ensure good coverage, a range of 50-200 GPA is recommended. Do not apply MVP II in volumes to runoff.
• To improve coverage and deposition on crop foliage the addition of a labeled sticker is recommended. Avoid using excessive rates of spreading or wetting adjuvants that will promote runoff of MVP II.
• When tank mixing MVP II with other insecticides, comply with the most restrictive label instructions of all products which are included. MVP II can be tank mixed with Promalin, Thinex, and other post bloom thinning materials.
• It may be necessary to reapply MVP II if rain occurs within six hours after treatment.

APPLICATION TIMING:

Always target sprays against newly hatched larvae. For optimal timing, scout for moth flights, eggs and newly hatched larvae.

POME FRUITS (apples and pears): Pandemis and Oblique banded leafrollers.

Recommended rates: 1.5 - 2 quarts per acre.

Early Season Control - (overwintering leafrollers). Apply at pink stage followed by a second application during bloom to petal fall before leafrolling occurs.

Mid to Late Season Control - Apply MVP II on a 7-10 day interval or as needed to control reinfesting or increasing leafroller populations. In orchards where both leafrollers and codling moths are present, MVP II can be tank-mixed with Guthion (azinphosmethyl) as an adulticide to disrupt lifecycles of both pests.

STONE FRUIT (cherries, peaches, apricots, nectarines, and plums) Peach twig borer (PTB), oriental fruitmoth, and leafrollers.

Recommended rates: 1.5 - 2 quarts per acre. Contact your local extension service for optimal timing for your area.
