  Control of Purple Loosestrife Now a National 4-H Project In the near future, purple loosestrife, an attractive but invasive wetland plant, may have nowhere to run. A biological control program to introduce the natural enemy of purple loosestrife, the Galerucella beetle, into local wetlands, has been accepted into the National 4-H Collection of youth development curricula. The "Biological Control of Purple Loosestrife" will be used by 4-H volunteers across the United States.
