What Is The Most Numerous Animal On The Planet?
As parasites, they are an unfortunate fact of life for all species of plants, animals, insects, and people. While not as infamous as bacteria or viruses, nematodes are parasites that exist in almost every species.
At the moment copper is gathering quite a reputation for it’s antibacterial and anti-viral properties. Now the question is being asked can copper also help reduce the damage caused by nematode infections that are commonplace in agriculture, livestock and humans?
Copper-iron nanoparticles were shown to paralyze and kill root-knot nematodes in tomato plants while increasing plant growth.6 Interestingly, copper is an important trace element and always present in healthy soil that supports vibrant plant growth.
Copper Is A Safe Nematicide Alternative
It’s important to always consider how the use of nematicides affects the environment and our health.
One major concern with any treatment protocol is the issue of parasites that survive a nematicide treatment will reproduce new strains more resistant to future nematicide treatment.
If copper proves to be an effective treatment against nematodes, it would be a significant breakthrough in agriculture, animal husbandry and our health care.
Currently, there aren’t any medications containing bioavailable copper designed to counteract nematode infections in humans.
One advantage of using copper in medication is, given in the correct dose, copper can be utilised by the human body with nutritional benefit, and without side effects11
The humble metal copper has especially attracted attention in recent times for use as a passive disinfectant material as touch surfaces in hospitals. This has encouraged more research on the subject of its potential in other medical applications.
Copper is an important element in many biological processes. Combined with its ability to destroy microbe DNA in bacteria and viruses that could otherwise develop resistance to other disinfectant protocols, copper is also a promising element to explore in the development as a nematicide.
