Asian soybean rust, which was discovered recently in one Louisana field, may have spread a bit further than first thought. Tests are expected to confirm that three more Louisiana fields are infected with the fungus, as well as a Mississippi field.
Suspicious plants were found late last week at the four fields. Tests were expected back Nov. 15, according to a Reuters' news service report.
The disease was originally confirmed at two Louisiana State University fields. USDA sent a team out to inspect and sample crops within a 50-mile radius of the infected fields. Mississippi and Arkansas officials also inspected fields.
Soybean futures rose at CBOT early Monday on the news of additional fields probably being infected. Soybean rust can dramatically reduce soybean yields and the overall crop. Countries dealing with the disease also face soybean export bans.
Some infected crops in Africa and South America have been known to suffer 80 percent yield losses due to Asian soybean rust. Fungicides can be used against the disease.
It is positive that the U.S. soybean harvest is nearly or totally complete. It will allow some separation and preparation time to address the disease before planting begins again.
