positive enhancing below ground roots with extra CO2 …

It’s well known about the ability of additional atmospheric CO2 to increase crop yields and greenery in general, while using less moisture. This latest research shows that extra CO2 available is extremely positive for root systems when pesticides are used:

Plant Root Loss to Herbivores Reduced by Aerial CO2 Enrichment (10 October 2016)
Atmospheric CO2 enrichment sometimes has its greatest positive impact below ground on plant root growth and maintenance…

The benefits only happen with elevated CO2:

[…] that “crops could tolerate attack in a CO2 enriched environment,” but that they could not do so under the current ambient CO2 concentration. And so they go on to conclude, at least in the case of raspberry plants, that “biotic interactions appear as important as direct effects of elevated CO2 on crop productivity.”

What can’t CO2 do!
