Orchard Pest Management

Integrated Pest Management

Integrated pest management (IPM) involves using several control strategies based on knowledge of a crop, its pests and their associated natural enemies to avoid crop loss and minimize harmful effects on the environment. Implementing IPM requires an understanding not only of insect and mite biology and ecology, but also knowledge of the entire orchard system. This includes the plants and animals that comprise the orchard community, as well as consideration of contributions from the surrounding habitat. The ‘orchard system’ also takes into account financial, physical and human aspects of orchard operations.

Seasonal insect and disease control requires adequate monitoring, properly timed control and appropriate choice of cultural, insecticidal and biological controls. The WSU Decision Aid System (WSU-DAS) is an online tool that assists with control efforts through the use of insect, mite and disease models that help to predict when pests are best controlled along with providing assistance with choosing an appropriate recommendation for your situation. The Crop Protection Guide for Tree Fruits is another resource that offers the latest options in control for commercial orchards.

Proper monitoring requires an understanding of pest/disease biology and protocols for trapping.  Monitoring techniques and insect/mite information are included in the online Orchard Pest Management book. The Pest Management Transition Handbook also has information for monitoring key insect pests and examples of control programs.

Thanks to WSU research, IPM continues to evolve. In a global marketplace, it is inevitable that new pests will invade. But as they do, scientists continue to find new control techniques. And that’s a good thing for the Washington tree fruit industry, because consumers’ concerns over insecticide residues on food, contamination of the environment, and exposure of farm workers to insecticide residues during thinning, tree training, and harvesting operations are issues of increasing importance. IPM addresses each of these concerns. Learn more »

Primary Resources for Orchard Pest Management

The WSU Decision Aid System (WSU DAS) integrates weather data with models for insects (10), diseases (4), and horticultural conditions (2). Add to that integration with the WSU spray guide, a pesticide effects database and MRL information and you have a very powerful orchard management tool. (Subscription required.)

The WSU Crop Protection Guide doesn’t only have control recommendations. This guide also includes basic information about concepts of integrated pest management, resistance management, and principles of biological control.

The Pest Management Transition Project Handbook is an excellent source of information covering the use of mating disruption, OP replacements, resistance management, how to monitor for pests, and much more. And, its also available in Spanish.

Orchard Pest Management Online has a collection of both pest and natural enemy descriptions. The descriptions include information about their biology, behavior and phenology. Much of this information is being updated and integrated into the Tree Fruit website. Look for Orchard Pest Management under Crop Protection in our navigation menu to see a list of the updated content.
