Sorry, no etymologies found.
But fungi, bacteriae, viruses, can be made to combat, control and balance each other; depending on the conditions under which their propagation is either facilitated or inhibited.
From the two foregoing examples it is seen that in the case of banana blight, fungi had to be suppressed by bacteriae, but that for pine trees on poor English soils fungi had to be activated for proper tree nutrition.
Fungicides are valueless where plant disease is caused by bacteriae which invade the water conducting tubes, (roughly corresponding to the blood vessels of mammals), of plants, tree trunks, etc. and prevent the flow of water and nutrient solutions from roots to leaves.
This was a matter not of the presence or absence of any one inorganic nutrient, but of restoring to soils the balance of fertility, an abundance of organic matter as food for bacteriae.
In a state of active life the bacteriae are interesting to study.
