Microscopic soil organisms could be an environmentally friendly way to control crop pests and diseases and even protect agriculture against the impacts of climate change, a leading researcher says.
Africa is battling an outbreak of trans-boundary pests and diseases like the invasive South America fall armyworm (FAW), tomato leaf miner and the TR4 which have cost the agriculture sector millions of dollars in crop damage.
“Research from our labs at Auburn University has shown a great potential in microbes for helping fight pests- and we have done some research on fall army worm that are pests in turf grass,” said Dr. Esther Ngumbi, a post-doctoral researcher in the Department of Entomology and Plant Pathology at the Auburn University in Alabama, United States.
Ngumbi’s research has looked at how beneficial soil microbes help recruit natural enemies.
Microbes are tiny organisms like bacteria and fungi that interact with the soil and plants. Though not widely appreciated in much of Africa, Ngumbi said microbial formulations have been found to improve plant growth and protect crops from insects, drought and other climate-related extremes.
Researchers also say microbes can help preserve the environment threatened by growing reliance on chemical solutions in fighting crop and livestock trans-boundary pests and diseases. Pesticides pose a threat to food safety, human and ecological health, necessitating the promotion of non-chemical alternatives to handling pests.
