Research Project: Alternatives to Fumigating Greenhouses for Control of Soilborne Plant Pathogens

Location: Horticultural Crops Research

Project Number: 5358-12220-004-15
Project Type: Grant

Start Date: Aug 29, 2012
End Date: Sep 30, 2014

Objective:
1. Optimize and determine the feasibility for solarization to disinfest greenhouse in-ground beds and used containers. 2. Determine if the addition of biocontrol agents to solarized soil will reduce disease caused by soilborne plant pathogens.

Approach:
Attempt to optimize solarization conditions to achieve higher soil temperatures, and follow solarization with amendment by biological control organisms to further suppress surviving pathogen inoculum. We will also test greenhouse solarization as a means of disinfesting used containers.
