ALERT: Soybean rust found on kudzu in Liberty County, Texas
|
8/23/2006 Update 6:30 a.m. CDT -- Asian soybean rust has been detected on kudzu near Dayton in Liberty County in eastern Texas 8/20. This was the first rust found in the state since rust was confirmed on late-planted soybeans harvested Feb. 14 in Hidalgo County.
That made 34 U.S. counties in six states that have had soybean rust confirmed in 2006. Rust was found on kudzu in Liberty County, also near Dayton, on Nov. 10, 2005 -- the first soybean rust ever in Texas. The new rust was found int he same patch this year.
In today's commentary on www.sbrusa.net, Texas officials said:
"Soybean rust has been detected at low levels in kudzu near Dayton (Liberty County). No rust seen in nearby soybeans or in kudzu to the north. There have been scattered thundershowers during the past week, but hot, dry weather will not support development of an epidemic in the next few weeks.
"Commercial soybeans and sentinel plots in southern Texas are approaching maturity or are being harvested. Group V soybeans in Liberty County are at R7 to R8, while Group VII soybeans are at R1 to R2.
"At this time, I am not recommending preventative applications of fungicides. We will monitor the progression of rust in Liberty County and work closely with the growers there to determine the appropriateness and timing of fungicide applications. Growers in other areas of the state should continue to monitor for rust.
Update 8/23/2006
Tom Isakeit of Texas A&M, the state soybean rust coordinator for Texas, added these details in an update e-mail to colleagues:
"The infamous kudzu patch near Dayton (Liberty County) has rust again.
The incidence is about 90 percent of leaves in a small area that I examined. There are about 5-200 pustules per leaflet, in very small lesions. Many of the pustules were not well-developed, but the amount of sporulation improved with overnight incubation.
"It was the last stop of the day, and I was rained out before I could check out more of the patch. I was last out here in mid-July and didn't see anything. The county agent has been checking it more frequently since then. There were periodic showers in the area over the past two weeks."
