An innovative plant growth promoting rhizobacteria (PGPR) for canola
BioBoost is a PGPR currently registered for use on canola in Canada. The liquid formulation, which is applied as a post emergent spray, received registration in late spring 2010. The objective for the 2010 growing season was to establish a series of field scale side by side trials to test and prove the performance of the product under commercial conditions.
BioBoost Liquid is showing an average yield response of 2 bu/acre (or 5% yield advantage) across 85 trials conducted between 2007 and 2010.* This includes 47 trials successfully taken to harvest in 2010. Undoubtedly some of the 2010 trials were adversely affected by the extreme wet conditions across much of Western Canada or the dry conditions in the Peace region. However, all trials deemed to be a fair representative trail on both sides by the co-operator were added to our database of trials - win, lose or draw.
How it works
The active ingredient, the bacteria Delftia acidovorans, is active in the soil. It is attracted to root exudates and will move toward growing roots and colonize the root zone. The bacteria have a number of beneficial modes of action that positively impact plant root growth; this ultimately supports higher yields, depending upon environmental and soil conditions.
Modes of Action - Delftia acidovorans
- The organism is a known sulphur oxidizer and may make more sulphur plant- available; and/or
- The organism may stimulate root and root hair development, thus helping the plant access more water and nutrients in limiting environmental conditions; and/or
- The organism is an aggressive root colonizer and may out-compete other soil bacteria and fungi.
In any given field and/or year one or more of these modes of action can be responsible for increasing canola yields.

* Average yield response on 85 trials (replicated small plot and strip trials), conducted from 2007 to 2010.
**Based on BioBoost trials as well as experience in the US in 2009, no impact on weed control efficacy was noted when tank mixed with Roundup or glyphosate. When tank mixed with glyphosate only apply on Roundup Ready canola.
