This article describes how to determine vineyard nutrient needs through grapevine tissue and soil sampling. It also provides tissue testing guidelines.
Pacific Northwest blueberry growers must identify and control a number of bacterial and fungal diseases in order to ensure the highest yields. Fortunately, only a few of the diseases that occur on highbush blueberry in this region cause significant losses when left unchecked.

Excessive summer irrigation of oak and madrone trees may promote fungal diseases such as the oak root fungus (aka armillaria root disease) and crown rot.
This is a guide that can be used by wine grape growers to interpret their vine tissue nutrient analysis results to determine nutrient sufficiency, deficiency or excess.
The intent of this add-on exercise is for PSA grower course trainees to think through various harvest and post-harvest scenarios and consider implications related to produce safety in the context of real production environments. Each group of trainees (4-6 per group) is given a set of the printed photos to work through. They are asked specific questions, and given 15-20 minutes to work in their groups. Following group discussions, trainers go through the slide deck and ask participants to share what they discussed in their groups about each scenario.
