TPTH or Tin fungicide (Super Tin, Agri-Tin) is under review for re-registration by EPA, who has some concerns regarding its use. EPA has a comment period open until March 15. Growers should respond with comments at the link below regarding the importance and value of TPTH as a part of our arsenal of fungicides with which to control pecan scab. Be sure to mention its value for resistance management in rotation with and in tank mixes with other fungicide materials. TPTH is an important tool for managing pecan scab. If growers do not voice their concerns over this, they are at risk of losing these products as part of their pecan scab program.
