Section 3 registration decision is expected by the end of June, 2008.  This could result in tebuconazole being available on soybeans this season.  However, as a backup plan, Georgia has submitted a request to renew the expired tebuconazole Section 18.  If approved, the USEPA will invite other states to submit “piggy-back” requests much as was done with the initial soybean rust Section 18s.
