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.

The goal of this project is to boost the number of fresh and processing sweet corn producers in Québec using trichogramma to control European corn borer.

In this study, we will test alfalfa meal pellets in a broccoli crop planted on plastic-covered irrigated mounds and we will compare them with two organic fertilizer, in addition to a control treatment in which no nitrogen is added.
Evaluation of the potential of drones to optimize trichogramma releases against the European corn borer on processing sweet corn in Québec.
