Assessment of weed control products applied along the edge of plastic mulch in organic agriculture
Maryse Leblanc
Researcher, agr., Ph.D.
Description
An initial experiment consisted of evaluating the weed control potential of a single dose of a series of herbicides listed in the manual on organic agriculture inputs (Manuel d’intrants biologiques) with a view to eliminating ineffective products. The herbicides were applied to two weed species (Chenopodium album and Echinochloa crus-galli) at the two-leaf stage. In a second experiment, products shown to be effective in the first phase were tested at different doses on the same weed species at the same stage to determine the optimum dose. The selected oils were also mixed with a biologically neutral liquid soap to check whether the soap has a synergistic effect that could reduce the amount of oil required. In a third field experiment, the most promising products were applied directly at the junction between the plastic and the soil to test their effectiveness on plants naturally present in the field.
Objective(s)
- Select a series of herbicides that can be used along the edge of the plastic mulch
- Determine the optimum dose for the selected products
- Evaluate the most promising products for their weed control potential and impact on the plastic

A status report on the labile carbon to total organic carbon ratio of Saguenay–Lac-St-Jean soils
A labile carbon input would displace some phosphorus into the soil solution, thus making it available again for assimilation into growing plants.

Evaluating the effect of seeds coated with commercial, mycorrhizal fungi inoculum on the yields of nantes carrots grown in mineral soil early in the organic transition process
Test whether or not commercial strains coated on Nantes carrot seeds can compete with native strains in the soil to colonize the host plant and, once symbiosis takes place, whether they succeed in doing a better job than the native strains during the transition to organic farming.
