NOXIOUS WEEDS IN PA § 110.1. Noxious weed control list, adopted May 19, 1989, amended April 11, 1997, effective April 12, 1997, 27 Pa.B. 1793; amended November 17, 2000, effective November 18, 2000.

The Noxious Weed Control Committee establishes the following noxious weed control list:

(1) Cannabis sativa, commonly known as marijuana.

(2) The Lythrum salicaria Complex: Any nonnative Lythrum including, Lythrum salicaria and Lythrum virgatum, their cultivars and any combination thereof.

(4) Rosa multiflora, commonly known as multiflora rose.

(5) Sorghum halepense, commonly known as Johnson grass.

(6) Carduus nutans, commonly known as musk thistle.

(7) Cirsium vulgare, commonly known as bull thistle.

(8) Datura stramonium, commonly known as jimson weed.

(9) Polygonum perfoliatum, commonly known as mile-a-minute.

(10) Puerria lobata, commonly known as kudzuvine.

(11) Sorghum bicolor cv. drummondii, commonly known as shattercane.

(12) Heracleum mantegazzianum, commonly known as Giant Hogweed.

(13) Galega officinalis, commonly known as Goatsrue.

The Department of Agriculture (Department) amends § 110.1 (relating to noxious weed control list) to designate Lythrum salicaria (purple loosestrife), Lythrum virgatum and their cultivars and combinations thereof as noxious weeds and to add Galega officinalis (Goatsrue) and Heracleum mantegazzianum (Giant Hogweed) to the noxious weed control list. The text of this amendment is set forth at 30 Pa.B. 636 (February 5, 2000).

The sap of this plant can cause rashes on the skin of persons with whom it comes into contact.

The addition of Goatsrue to the noxious weed control list will provide the Department needed authority to address the presence of this nonindigenous plant at the Philadelphia area location where it has been detected. This plant is toxic to livestock.

Lythrum salicaria, commonly known as purple loosestrife, is a nonnative wetland plant that thrives in the absence of the insects and diseases that controlled it in Europe and Asia.
