Biocontrol Delivery Technology Development
There is a big difference between getting a pathogen to cause disease under laboratory conditions and creating an inoculum delivery system that can be used for effective biocontrol in the field.
What it's about
What we did
What we found out
We have spent several years working on the technology for producing the pathogen in liquid culture, persuading it to sporulate on a solid carrier, and then testing this bulk inoculum in field inoculation trials.
We have been able to significantly reduce the density of the persistent cheatgrass seed bank using this bulk inoculum in every field trial, and in some cases we have achieved complete control. Our task now is to develop a lighter-weight carrier system with more concentrated inoculum, and to develop methods to maximize shelf life and minimize production costs, so that this biocontrol product can be commercially produced.
