Hypothesis
Intercropping maize with legumes, T. harzianum application, and the push–pull method will reduce damage to maize by herbivores and reduce the dispersal of mycotoxigenic fungi and associated aflatoxin contamination, while maintaining or increasing productivity.
Conclusion
Maize–legume intercrops and push–pull technology reduced pest damage and aflatoxin contamination in maize.
Supporting Evidence
- The push–pull cropping system significantly reduced the prevalence of the fall armyworm.
- Beetles were found to carry mycotoxigenic fungi on their bodies, indicating a potential for passive dispersal.
- Intercropping with legumes improved soil health and reduced pest damage.
Takeaway
This study shows that planting maize with beans and using special techniques can help keep bugs away and make the corn safer to eat.
Methodology
Field study conducted in Kenya using randomized complete block design with treatments including maize monocrop, maize intercropped with beans, maize–bean intercrop with Trichoderma harzianum, and push–pull technology.
Limitations
The study was limited to two regions in Kenya and may not be generalizable to other areas.
Participant Demographics
The study involved maize crops in Kisumu and Makueni counties in Kenya.
