Three genera of duckweed occur in this area, and all are small, free-floating green plants that form large blankets on the surface of sheltered water. From one to six roots may dangle from each plant. Duckweeds are the smallest of flowering plants, but reproduction is generally vegetative. The most common are (A) little duckweeds (Lemna spp.), (B) large duckweeds (Spirodella spp.), and (C) water meal (Wolffia sp.).

Duckweed is abundant throughout Mississippi in ponds, lakes, and sluggish streams. In some cases it can become a serious pest but can be controlled with relative ease with either treatment listed. Read and follow label instructions before using any chemical in water.
