Leveillula taurica

Leveillula taurica is a species of fungal pathogen that is part of the Erysiphales order. It is known for causing powdery mildew in a wide range of crops and plants.

Taxonomy

The species was first described by Pierre Bulliard in 1791. It was later reclassified as Leveillula taurica by Augusto Chini in 1903. The species belongs to the Leveillula genus, which is part of the Erysiphaceae family.

Description

Leveillula taurica is a biotrophic fungus, meaning it derives its nutrients from living plant cells. It is characterized by its powdery white appearance on the surface of infected plants. The fungus produces conidia (asexual spores) that are wind-dispersed and can infect a wide range of host plants.

Hosts and symptoms

Leveillula taurica has a broad host range, including important crops such as tomato, pepper, onion, eggplant, and cotton. Symptoms of infection include chlorotic spots on the upper leaf surface, and a white, powdery growth on the lower leaf surface. Severe infections can lead to leaf curling, stunting, and yield loss.

Management

Management of Leveillula taurica involves a combination of cultural practices, biological control, and chemical control. Cultural practices include crop rotation and the use of resistant varieties. Biological control involves the use of biopesticides, while chemical control involves the use of fungicides.
