Four engine aircraft experience in the application of Bacillus thuringiensis against the spruce budworm in Quebec

Abstract

I want, during this presentation, to give you a spray program coordinator point of view on Bt and try to explain why things are always different in Quebec. Not always better but always different, even in the application of Bacillus thuringiensis where 4 engine aircrafts were used to control the spruce budworm, Choristoneura funiferana (Clem.), infestation. First, a background of the situation is required: background of the Quebec forest and background of our perception of Bt. In order to progress in our approach to use Bt , some KEY FACTORS and GOALS have been established. This brought us into two major periods in the use of Bt: the 1971-1980 period where we learned to live with Bt and its constraints, and the 1981-1983 period where some of the constraints have been solved to a certain degree. Finally, the 1984 project is discussed.
