Blueberry irrigation scheduling: When, where, and how much?

Educational Document

Irrigation scheduling, a key element of proper water management, is the accurate forecasting of water application (amount and timing) for optimal crop production (yield and fruit quality). The goal is to apply the correct amount of water at the right time to minimize irrigation costs and maximize crop production and economic return.

There are, however, strategies that help to control weeds in blueberry. This article will discuss some thoughts about weed control in blueberry, and some of the strengths, and weaknesses, of currently registered herbicides.

Blueberry bacterial and fungal diseases

Article

Pacific Northwest blueberry growers must identify and control a number of bacterial and fungal diseases in order to ensure the highest yields possible (profitable yields). Fortunately, only a few of the diseases that occur on highbush blueberry in this region cause significant losses when left unchecked.

Fruit and Ornamental Disease Management Testing Program

Online Resource

The primary purpose of the fruit and ornamental disease management testing program is to provide Oregon growers, Extension Faculty, and Field Representatives with unbiased information on the relative efficacy of fungicides, fungicide schedules or cultural practices for control of plant diseases. Treatments evaluated are not restricted to chemical fungicides and may involve use of cultural controls, biological controls and other innovative materials that show promise in controlling disease. Our objective is to broaden the scope of methods used to reduce crop loss due to diseases and to service the diverse management practices of Oregon growers. The results are compiled and sent to county agents, field people, company representatives, and to interested growers directly. The information gained from these trials is used to formulate disease control recommendations for Oregon's diverse agricultural crops.
