Soybean Rust Early

The LSU AgCenter says Asian soybean rust is showing up earlier and in more places than usual.  Plant pathologist Clayton Hollier (OH-yay) says it has shown up in eight parishes, mainly along the coast, and in 6-inch-high “volunteer” soybean seedlings. He says that indicates that the fungus can survive through a mild winter.  The disease is known to attack more than 100 host plants, with soybeans and kudzu the most susceptible.  It was found Jan. 2 in kudzu on Perkins Road in Baton Rouge.  The early start means soybean growers may need to use fungicides earlier than usual.
