S.C. Code Regs. 27-12. Destroying Pines

In order to suppress any centers of blister-rust infection, the South Carolina State Crop Pest Commission or its agents are authorized to destroy five-leafed pine trees either (a) when the trees are found infected with blister rust, or (b) when the cultivated currant and gooseberry plants in the vicinity are of more value than the five-leafed pines, or (c) when the cost of removal of the wild and cultivated currant and gooseberry plants within an infective distance thereof would be greater than the value of the white pine trees involved.
