Leaf Extracts from Resistant Wild Tomato Can Be Used to Control Late Blight () in the Cultivated Tomato.

Late blight disease, caused by (Mont.) de Bary, is one of the most challenging diseases threatening tomato production and other Solanaceae crops. Resistance to late blight is found in certain wild species, but the mechanism behind the resistance is not fully understood.

Paclobutrazol Improves the Quality of Tomato Seedlings to Be Resistant to Blight Disease: Biochemical and Histological Perspectives.

The production and quality of tomato seedlings needs many growth factors and production requirements besides controlling the phytopathogens. Paclobutrazol (PBZ) has benefit applications in improving crop productivity under biotic stress (, the causal agent of early blight disease in tomatoes). In the current study, the foliar application of PBZ, at rates of 25, 50, and 100 mg L, was evaluated against early blight disease in tomatoes under greenhouse conditions.
