Monitoring Botrytis fungicide resistance on blueberries in Washington and Oregon

Gray mold, caused by Botrytis spp., is a major issue for blueberry crops in the Pacific Northwest (PNW), leading to losses in yield and quality. This study examined the pathogen's in vitro resistance to various fungicides, collecting samples from 35 fields in 2022 and 2023, resulting in 376 and 339 Botrytis isolates, respectively.

Rootstock and scion influences on grape and wine composition and quality

Phylloxera is the most significant insect pest of wine grapes throughout the world that cannot be controlled by chemical or biological means. Grafting susceptible wine grapes onto tolerant rootstocks is the only long-term insurance against this devastating root pest.

Understanding the diversity of nepoviruses in small fruits and grapes in the Pacific Northwest and the risk associated with their nematode vectors

The main objective of this research were to generate information on small fruit and grape virus diversity in the Pacific Northwest focusing on viruses transmitted by nematodes. The $840 million small fruit industry in the PNW faces several phytosanitary risk scenarios, one of these is the emergent or re-emergent viruses transmitted by nematodes.

Prevalence of cranberry fruit rots in commercial production beds in Oregon and Washington

Oregon and Washington are the fourth and fifth leading producers of cranberry in the US. Cranberry is a perennial crop with production and harvest practices unique among the small fruits. Some of the cranberry beds in the PNW are decades old. As expected with older cranberry beds, a portion of the cranberry crop is routinely lost to various fruit rots.
