Funded Project
Funding Program: IPM Partnership Grants
Project Title: New England Small Fruit IPM Field Manual
Project Director (PD):
Sonia G. Schloemann [1]
Lead State: MA

Lead Organization: University of Massachusetts
Undesignated Funding: $19,220
Start Date: May-01-2010

End Date: Apr-30-2011
No-Cost Extension Date: Apr-30-2012
Pests Involved: tarnished plant bugs, two-spotted spider mites, blueberry maggots
Site/Commodity: strawberry, strawberries, blueberry, blueberries, raspberry, raspberries
Summary: This proposal seeks funding by the Northeast Integrated Pest Management Center under the IPM Partnership Grant program; section C (Regional IPM Publications), for the development of a New England Small Fruit IPM Field Manual. This publication will serve as a companion to the New England Small Fruit Pest Management Guide providing detailed information on pest identification and crop damage (photos), pest life cycles and crop susceptibility (graphics) for key small fruit pests along with the text describing monitoring methods, economic and action thresholds, and a suite of management tactics including cultural, biological, mechanical, and chemical methods. A variety of IPM information is available for small fruit growers in various print publications and on-line, but no single source currently provides all this information in one place for New England producers. As interest in establishing sustainability standards nationally and locally increases, growers need practical tools to guide them in implementing recommended practices. IPM methods are key to growers' success in this environment. This manual will provide the practical pest management information that growers need. Professionals from Extension, NOFA, Experiment Stations throughout New England will contribute content to this publication. Producers and independent crop consultants will participate in reviewing this publication. It will be available as a print publication, series of fact sheets, and as a searchable online resource for growers that will be accessible from each state's Extension website. A condensed form may be made into a pocket guide in the future.


Objectives: The objective of this project is to plan, develop and publish a New England Small Fruit IPM Field Manual

The design of the publication will allow for access in several formats; print hard copy, individual electronic factsheets, and for inclusion in a larger IPM web portal (similar to the Ontario Crop IPM site). It will be available for distribution by collaborators as well as posting on their websites. Producing this publication in varied formats will expand its accessibility to the target audience. In addition, the electronic format will be conducive to expansion and updates as new information is added or developed. The project director will devote the time needed to carry out planning steps, gathering content from regional collaborators, consult the advisory team to review drafts, and produce final copy for the proposed publication.

The resulting publication will provide small fruit producers, crop consultants, Extension staff, NRCS staff, and others a comprehensive, up-to-date, accessible resource for guiding IPM practices or assessments for commercial strawberry, highbush blueberry and raspberry production. Over time, additional small fruit crops may be added.

Proposal

Interim Report: Jun-29-2011

Impacts
Since the project has received a 1 yr extension, impacts have not yet been measured. Impacts will be reported at the conclusion of the project.

Outcomes
Full draft of print publication and intended website are not yet complete. However, some sections of the Guide have been used to produce IPM Berry Blasts during the 2011 growing season (see brief example below). Six berry blasts have been produced to date and distributed to 293 email recipients. Pests covered include:

Strawberry:
Tarnished Plant Bug, Strawberry Bud Weevil, Two-spotted Spider Mites, Strawberry Sap Beetle, Black Vine Weevil, Botrytis Gray Mold, Bacterial Angular Leaf Spot.

Raspberry/Blackberry:
Tarnished Plant Bug, Strawberry Bud Weevil, Two-Spotted Spider Mite, Raspberry Fruitworm, Raspberry Cane Borer, Potato Leafhopper, Botrytis Gray Mold

Blueberry:
Cranberry Fruitworm, Blueberry Maggot, Aphids, Mummyberry, Botrytis Gray Blossom and Twig Blight, Anthracnose

Strawberry Sap Beetle:(see http://www.nysipm.cornell.edu/factsheets/berries/ssb.pdf for IPM fact sheet on strawberry sap beetle)

ID/Life Cycle: Adults are small oval beetles, dark brown in color. They are often hard to see because they drop to the ground when disturbed, but they may be found in the cavities they have chewed out. They are found almost exclusively when there is ripe fruit in the field.

Damage: Sap beetles cause hollowed out cavities on ripe fruit, an injury very similar to slug injury.

Management
Monitoring: Strawberry sap beetle can be monitored by direct observation of ripening fruit to see if feeding has occurred. Bait traps with ripe fruit or bread dough can also be used to attract sap beetle to determine if a significant population is present.

Control strategies
Cultural/Biological:

- Rotate strawberry fields to alternative cash or cover crops for at least 3 years before replanting to strawberries to disrupt pest buildup.

- Ensure timely and complete picking of ripe fruit and the removal of over-ripe and damaged berries from the field.

- Place trap buckets of over-ripe fruit or bread dough outside field borders to intercept migrating beetles and reduce pest numbers in the crop.

- Preserve natural enemies whenever possible by selecting spray materials that are less toxic to beneficials.

- Avoid planting strawberries near alternate hosts such as raspberry, sweet corn, and melons to reduce overwintering populations.

Chemical:

- Apply recommended insecticides ONLY if infestation is severe due to harvest restrictions.
