Potato wart eradication program in Pennsylvania
- 26 Downloads
A well enforced State quarantine has prevented spred of the potato wart disease from the original infested areas in Pennsylvania.
The early finding of immunity in American varieties and in many of the developed seedlings, has provided a means of control.
The establishment of wart disease is limited to areas with cool, moist soils. There are, however, large areas in the United States with a climate similar to that of the infested areas of Pennsylvania.
Wart spreads slowly, usually by mechanical means or transportation of infected tubers, plants or soils.
The wart eradication effort in Pennsylvania is aimed toward complete eradication of the organism.
