Hypothesis
The study evaluates the antifungal efficacy of newly synthesized organophosphorus derivatives against sugarcane fungal pathogens.
Conclusion
The organophosphorus derivatives containing substituted chalcones showed significant antifungal activity against the tested fungi.
Supporting Evidence
- The compounds showed 70-85% mycelial inhibition against all test fungi at 1000 ppm.
- Derivatives containing 2-chlorobenzal-2'-hydroxyacetophenone showed up to 84% inhibition for C. falcatum.
- Other derivatives showed inhibition rates between 55.1% to 80.3% against all test fungi.
Takeaway
Scientists created new chemicals to help protect sugarcane from harmful fungi, and some of these chemicals worked really well.
Methodology
The antifungal activity was tested using the food poison technique at three concentrations (10, 100, 1000 ppm) against specific fungi.
Limitations
The study does not specify the long-term effects or environmental impact of the tested compounds.
