Creator:: Stone, Alex and Miyazoe, Mikio
Abstract:: This project is investigating whether low rate (goal: one pound per acre) early fall Contans applications to flailed diseased residues left on the soil surface can increase Cm inoculum and reduce Ss sclerotial viability.
Resource Type:: Technical Report

Creator:: Heinrich, Aaron and Stone, Alex
Abstract:: The goals of this project were to determine 1) if liming controls clubroot, 2) the pH that must be attained to achieve commercially viable levels of control, and 3) how best to lime (materials, timing, incorporation strategies) to achieve that pH.

Creator:: Stone, Alex and Johnson, Ken
Abstract:: Objectives: to determine the impact of 1.fall Contans applications on Coniothyrium minitans (Cm) infection and survival of sclerotia left on the soil surface through the winter and summer 2.the impact of summer irrigation and burial on sclerotial survival and infection with Cm and other fungi

Full Text:: Willamette Valley processed snap bean production. PI: Alex Stone, Dept of Horticulture Collaborator

Creator:: Heinrich, Aaron and Stone, Alex
Abstract:: This research has demonstrated that liming clubroot infected soils to a pH ≥7.1 is an effective practice for reducing both the incidence and severity of clubroot. Liming does not kill the pathogen but rather prevents disease spores from infecting the plant. This research demonstrated that highly reactive calcitic lime products...

Creator:: Seavert, Clark, Peachey, Ed, McGrath, Daniel, and Stone, Alex
Abstract:: 1) Develop and moderate a workshop to discuss hypothetical crop rotation strategies that would allow conversion of land to organic processed vegetable production without exacerbating weed or pest positions. • Invite industry leaders to help develop crop rotations • Invite potential forage consumers/buyers to help focus on projected forage needs...

Creator:: Stone, Alex, Miyazoe, Mikio, Weston, Galen, and Hertel, Michael
Abstract:: 1. Rotbusters Field Survey.  Kokanee and Basin were the only varieties sampled in 2005. There was a significant relationship between radicle rot severity and gross yield for Kokanee but not for Basin.  In previous years, we have shown that for Jubilee, approximately 3 tons of gross yield are...

Creator:: Nagy, Andy, Stone, Alex, Myers, Jim, and Peachey, Ed
Abstract:: With the hot summers of recent years causing significant heat damage to broccoli heads within the Willamette valley, varietal screenings for newer and more heat tolerant varieties became necessary. Most commercially available broccoli varieties are bred for production within milder and more climatically stable regions, such as the Salinas Valley...
