Management
The main form of spreading of P. fragariae is through infected material. Strict regulations in many countries have been instituted regarding the transportation and disposal. For instance, Norway requires an official statement saying that the location you are planting has not been known to host P. fragariae and that the plants you are planting show no symptoms. Fosetyl-alcohol and fungicides have been approved for use against P. fragariae. These chemicals, when applied in late autumn just before the infection of new roots, have been proven to be effective against var. fragariae, but not var. rubi. Fungicides containing phenylamides have been approved when applied in early spring or late autumn. Some strains with phenylamide resistance have been found and have proven to be problematic in Germany and North America. Resistant plants have been bred and are commercially available. The resistance may be race specific and usually used where one strain is predominant. Due to the importance of water in germination and infection, good drainage can help reduce the proliferation of the disease.

“Why not draft executive and management brains to prepare and produce the equipment the $21-a-month draftee must use and forget this dollar-a-year tommyrot? Would we send an army into the field under a dollar-a-year General who had to be home Mondays, Wednesdays and Fridays?”

“No officer should be required or permitted to take part in the management of political organizations, caucuses, conventions, or election campaigns. Their right to vote and to express their views on public questions, either orally or through the press, is not denied, provided it does not interfere with the discharge of their official duties. No assessment for political purposes on officers or subordinates should be allowed.”
—Rutherford Birchard Hayes (1822–1893)
