Can Earthworms be harnessed to carry bio-control agents?

This intriguing question is one of a number of research projects on the benefits of encouraging earthworms funded by growers through the GRDC.

A one year evaluation is looking at whether earthworms can be used to disperse biological control agents against cereal root disease.

The investigation will look at whether the microbes can survive passage through the intestines of earthworms; multiply in worm castings; and be dispersed through the root zone with earthworms.
