Final Photos of 2017 Fall Frost Tolerance Have Been Posted

The final fall frost tolerance sheet for 2017 has been posted.  All cultivars have reached a deep maroon color and their deepest frost tolerance temperature.  For Ben Lear and new Rutgers cultivars this tolerance is 24°F.  Stevens tolerate 22°F at this stage until late October when some loss of tolerance accompanies extreme ripening and Stevens once more must be protected at 23°F.  Early Black and Howes tolerate 23°F at the maroon stage.  In some years, Howes have tolerated temperatures as low as 20°F at the maroon stage but this was not the case in all years.

EPA Denies Section 18 Petition for Kerb

EPA reviewed the Section 18 request for the use of Kerb 3.3 SC to control dodder and determined our petition did not provide information that establishes an "emergency condition".  In order to use a pesticide not labeled for use, a non-routine event must be described and substantiated to confirm that the pest problem rises to the level of an "emergency".  EPA acknowledged that while dodder may be a difficult pest to manage, it is a routine condition.

Thus, Kerb CANNOT be applied to cranberry bogs! It is an illegal application.  Any questions, please call me.
