Recent scouting has indicated the unwelcome return of flag smut Urocystis agropyri to U.S. wheat fields this season. Arysta LifeScience is pleased to announce that select RANCONA Seed Treatment products have received FIFRA 2(ee) recommendation for flag smut control on wheat.
As a result, the RANCONA family of seed treatment products including RANCONA® PINNACLE, RANCONA® CREST, RANCONA® V 100 PRO and RANCONA® V RTU is recommended for use on wheat to control this disease in:
- Colorado
- Kansas
- Missouri
- Nebraska
- North Dakota
- Oklahoma
- South Dakota
- Texas
Flag smut is a fungus carried by spores that can be borne on seed, blown by wind short distances or moved with machinery. The spores, which may survive in the soil up to four years, infect the seed prior to emergence from the soil. Symptoms include dark streaks on the leaves of the infected plant and a twisted flag leaf.
“Flag smut tends to stunt growth and reduce tillering and can have a negative impact on yield,” notes Chris Wooley, Arysta LifeScience marketing manager, Seed Treatment. “Research1 shows that the use of an economical fungicide seed treatment like RANCONA is highly effective in preventing the presence of flag smut.”
Treating wheat seed with a member of the RANCONA family will help growers prevent a repeat experience with this disease challenge, as well as help prevent a number of other key yield- and profit-robbing diseases. Adds Wooley, “When growers choose RANCONA to help prevent flag smut, they also gain the following protections and benefits”:

“These formulations are known throughout the industry for their broad-spectrum control, ease of use, superior protection and incredible ability to uniformly adhere to seed coats, giving growers and seed treaters the security to know that seeds will be protected and seed treatment equipment will be easy to clean,” says Wooley. “This local recommendation also offers peace of mind that users are further protected from the reemergence of flag smut.”
Plus, growers who use RANCONA obtain the added benefits of faster plant emergence with increased stands and healthier, more vigorous plants that yield well.
