Part 1 of this project, conducted in both the laboratory and orchards, will assess the efficacy of the new Virosoft CP4 formulation in terms of its speed of action, virulence, and persistence. This will make it possible to satisfy some of the Pest Management Regulatory Agency’s requirements for an amended registration of the Virosoftnbsp;CP4 formulation. Partnbsp;2 of the study will be conducted in the laboratory and in experimental and commercial orchards, and will evaluate the effectiveness—in terms of speed of action, virulence, and persistence—of adding an adjuvant to the new Virosoftnbsp;CP4 formulation. Partnbsp;3 will be carried out in the laboratory and will address a problem regarding the compatibility of Virosoftnbsp;CP4 with another Bacillus thuringiensis (Bt)-based registered biological insecticide, as well as with fungicides used by a number of apple growers in organic orchards and in integrated fruit production.

In highbush blueberry fields where stunt disease has been detected, plants that have never received nitrogen fertilizer are more vigorous and homogeneous than plants that have received nitrogen fertilizer.
The apple leafcurling midge is a new apple pest in Québec. The aim of the project is to explore the pest’s phenology, establish variable economic injury thresholds, and incorporate the results into a phenology model in CIPRA.
