Abstract

Powdery mildew, caused by Podosphaera xanthii, is a significant disease impacting cucumber (Cucumis sativus L.) crops, leading to major yield losses. The study evaluates the efficacy of botanicals and biostimulants in managing powdery mildew under in vitro conditions. Treatments were tested at three concentrations (5, 7.5 and 10%) against P. xanthii. Results revealed that the efficacy of treatments increased with concentration, with Ascophyllum nodosum (seaweed extract), Mimosa pudica (touch-me-not) and Osmium sanctum (tulasi) demonstrating the highest inhibition rates at 10%. These findings suggest the potential of eco-friendly alternatives for managing powdery mildew in cucumber.
