 Indole and tetrahydroquinoline derivatives have been developed, with
some compounds showing superior activity compared to commercial
fungicides, such as trifloxystrobin(Wang et al., 2022).
  The structure-activity relationship analysis has guided the design of
these compounds, enhancing their antifungal properties(Wang et al.,
2022).

Challenges and Perspectives

Despite the promising results, challenges remain in the practical application
of these natural compounds, particularly regarding their stability and
persistence in agricultural settings(Din et al., 2023). Further research is
needed to optimize formulations that maintain efficacy over time.
Organic pesticides with fungicide properties present several advantages that
contribute to sustainable agricultural practices. These natural alternatives
not only mitigate the adverse effects associated with synthetic fungicides
but also enhance crop health and environmental safety.
