2/16/2007 10:30 a.m. CST -- Asian soybean rust was found yesterday on old-crop and volunteer commercial soybeans in a field in Hidalgo County, Texas -- the farthest west rust has been found overwintering this year.
The Texas commentary on www.sbrusa.net said the field near Monte Alto was harvested in December 2006. Rust was found on a handful of R6 plants the combine missed. A few pustules were found on volunteer plants (V2 to V3 stage). The field is scheduled to be disked soon and planted to sorghum.
The report said the over-wintering soybean rust sentinel plots planted at Weslaco, Texas, are still in the vegetative stage. Commercial soybeans won't planted in south Texas for several weeks yet, and "the soybeans with rust in Hidalgo County will be gone by then," the commentary said.
In other scouting, a commercial field about a mile away from the positive Hidalgo site was surveyed in November 2006, and no rust was found. This field then was also harvested around December 2006. As of Feb. 15, 2007, this field had volunteer plants present only, and there were no rust symptoms on these volunteers.
Some Georgia rust chilled out
The report from Georgia this week changed two positive counties to "confirmed, rust no longer found" because cold temperatures had knocked back the infected leaves in Miller and Thomas counties.
This was based on scouting for soybean rust on kudzu at mobile sentinel sites in Worth, Lee, Sumter, Terrell, Calhoun, Early, Miller, Seminole, Decatur, Grady, Thomas and Brooks counties, in southwest Georgia.
No new rust sites were found, and all kudzu was dead due to winter dieback, except for two locations (already confirmed) in Grady and Brooks Counties. These two sites were located in protected areas (behind buildings) in urban/industrial areas of the city. All leaves unprotected from the cold temps are dead, officials said.
