Evaluate the efficiency of bacteria-based biological products against Oidium neolycopersici on tomato

Powdery mildew (Oidium neolycopersici) represents a major threat to greenhouse tomato crops in Quebec. The severity of the disease, the wide distribution of the pathogen, and its increasing resistance to fungicides require urgent exploration of new alternatives. Faced with this challenge, the master's project aims to study innovative biological alternatives to control this disease. The study will verify the following two hypotheses: (1) biological bacteria-based products have prophylactic potential against greenhouse tomato powdery mildew and (2) tomato growth and production will be maintained following biological treatments. To achieve this, the following specific objectives were developed: (1) evaluation of the prophylactic potential of eight biological formulations based on bacteria against tomato powdery mildew, (2) determination of the persistence of biological control agents following their application using molecular approaches, and (3) study the impact of biological products on the growth and yield of greenhouse tomato crops.
