ALERT: Assumption Parish, LA, has high-level rust infection; more GA finds
|
9/18/2006 5:45 p.m. CDT -- A high-severity, high-incidence soybean rust infection was reported this afternoon in a commercial field in Assumption Parish, Louisiana. This is the 13th rust-infected parish in the state and 58th infected county/parish in the U.S. this year.
The Louisiana state commentary on www.sbrusa.net said the Asian soybean rust was found for the first time in the parish in a commercial field of Group IV soybeans in the late R7 stage.
"The incidence and severity levels were extremely high," the report said. This brings to 13 the number of parishes in which ASR has been found on either soybeans or kudzu.
The commentary also said harvesting has begun in many of the soybean growing areas, especially with early maturing varieties or those planted early. Some late-planted beans are in the latter-range reproductive stages.
Georgia finds additional rust in Tift, Grady counties
Georgia reported today that soybean rust was detected this past week on a soybean sample collected Sept. 8 from one of Georgia sentinel plots in Tifton, Ga., which is in Tift County, located in south central Georgia. This is the second rust find in that county this growing season.
Soybean rust was also found on kudzu (one leaf of 50 collected) in Grady County Georgia, which is located in south central Georgia, bordering Florida. This is also the second rust find in that county.
"Most of our soybean sentinel plots (MG-IV an MG-VI) are at the R8 growth stage as of 9/18/06," Georgia officials reported. "Commercial soybeans in our state range from about R6 to R7 stages."
At this point, including reports on kudzu, there are 58 counties in eight states with soybean rust infections this year: Alabama, five; Florida and Louisiana, 13 each; Georgia, 11; South Carolina, 10; Texas, three; Mississippi, two; and one in North Carolina. Thirty-eight of these reports were on soybeans.
Soybean rust infections have now drawn even with the count last year on this date, but in eight states, not just the five that were affected as of Sept. 18 last year. Counts are much lower in Florida (13 counties vs. 22) this year. The state counts last year in mid-September were Alabama, 15; Florida, 22; Georgia, 16; Mississippi, two; South Carolina, three.
