Downy mildew, caused by Peronospora belbahrii, poses a significant threat to basil (Ocimum basilicum)
crops. This study investigates the potential of Chromolaena odorata extract as a bioorganic therapy for Downy
Mildew. The goal of this research-based innovation is to determine the long-term and environmentally friendly
potential of C. odorata extract as an alternative to synthetic fungicides for controlling Downy Mildew in basil,
thereby contributing to SDGs 2 (Zero Hunger), 3 (Good Health and Well-being), and 15 (Life on Land). The leaves
of C. odorata were collected and extracted, and the bioorganic solution produced was tested for antifungal efficacy
against P. belbahrii. Next, C. odorata extracts at their respective concentrations (0.0001 g/mL, 0.0002 g/mL and
0.0003 g/mL were applied to the assigned plants within each block using the Randomized Complete Block Design
(RCBD) with three replicates per treatments. During field investigations, C. odorata extract demonstrated
significant antifungal activity against P. belbahrii. The findings suggest that C. odorata extract has potential as a
bio-organic treatment for Downy Mildew, which is consistent with SDG 12 (Responsible Consumption and
Production) by supporting sustainable farming practices that reduce reliance on chemical inputs. This innovation
is vital to modern farmers, particularly social enterprise entrepreneurs, as it facilitates healthy basil cultivation. In
a nutshell, the C. odorata extract has been evaluated for its efficacy in controlling mildew disease and has the potential
to be commercialized and marketed
