| Abstract/Contents: | "The 2020 Weed Survey for the U.S. and Canada surveyed the most common and troublesome weeds in the following grass crops: 1) corn (Zea mays); 2) rice (Oryza sativa); 3) sorghum (Sorghum bicolor); 4) turf; 5) pastures, rangeland, or other hay; 6) spring cereal grains; and 7) winter cereal grains. Common weeds refer to the weeds you most frequently see while troublesome weeds are the most difficult to control, but they might not be widespread. There were 317 total survey responses from the U.S. and Canada, of which 106 were from the following Southern Weed Science Society (SWSS) states: Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Mississippi, Missouri, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, and Virginia. The following weed survey results are for the 14 states in the SWSS region. The top three most common and troublesome weeds in corn were 1) Ipomoea spp.; 2) Palmer amaranth (Amaranthus palmeri); and 3) johnsongrass (Sorghum halepense). The top two most common and troublesome weeds in rice were 1) Cyperus spp.; and 2) Echinochloa spp. The top three most common weeds in sorghum were 1) Ipomoea spp.; 2) Palmer amaranth; and 3) a tie between johnsongrass and Urochloa spp. and the most troublesome weeds were: 1) Urochloa spp., 2) johnsongrass; and 3) Palmer amaranth. The top three most common weeds in turf were 1) Digitaria spp.; 2) annual bluegrass (Poa annua); and 3) Cyperus spp. and the most troublesome weeds were: 1) Paspalum spp., 2) annual bluegrass; and 3) Virginia buttonweed (Diodia virginiana). The top three most common weeds in pastures, rangeland, and other hay were 1) Cirsium/Carduus spp.; 2) Ranunculus spp.; and 3) horsenettle (Solanum carolinense) and the most troublesome weeds were a four way tie among: Cirsium/Carduus spp.; horsenettle; knotroot foxtail (Setaria parviflora); and smutgrass (Sporobolus indicus). The top three most common weeds in winter cereal grains were 1) Italian ryegrass (Lolium perenne L. ssp. multiflorum); 2) Lamium spp.; and 3) common chickweed (Stellaria media); and the most troublesome weeds were: 1) Italian ryegrass; 2) henbit (Lamium amplexicaule); and 3) a tie between horseweed (Erigeron canadensis) and annual bluegrass. The top three most common weeds among all grass crops in the SWSS region were 1) Digitaria spp.; 2) Italian ryegrass; and 3) Ipomoea spp. and the most troublesome weeds were: 1) Italian ryegrass; 2) Palmer amaranth; and 3) Ipomoea spp. The 2020 weed survey data is available at: www.wssa.net/wssa/weed/surveys/." |
