13880 + PROHEXADIONE CALCIUM ( BASF,FINEAMA ) HAZELNUT (FILBERT) ( 14-12 = TREE NUT GROUP ) POTENTIAL: E/CS DATA BEFORE APPROVAL FOR RESIDUE STUDY

Reduced Risk Status: THIS AI HAS BEEN CLASSIFIED AS RR FOR ONE OR MORE FOOD USES.
IPM Compatibility: Per Requester: Good Fit; Low environmental toxicity. Low non-target toxicity. Low persistence. Low risk of human exposure, treatments would be applied during intial shoot elongation period, harvest takes place months later and is mechanical. Consumer exposure minimal. Receiving stations have preemptive washing and protective shells are removed prior to kernel consumption by consumers.
Reasons for need: Plant growth regulator (giberrellin inhibitor) to help reduce plant vigor, keep trees small. Concentrate internodes for high density hazelnut production. Optimize hazelnut production with smaller trees that are more easily managed (smaller canopies can reduce use and drift of other pesticides), reduced costs for pruning, hedging and temporary tree removal. Potentially reduce disease, especially eastern filbert blight. We do not have access to dwarfing rootstocks in hazelnut production.
Requesting State(s): OR:Wiman, N* ;
PCR Use Pattern: Using the Apogee or Kudos product, make up to four foliar applications per season to hazelnuts for vegetative growth management. Rates will vary, ranging from 2 to 36 fl oz/a, based on several factors, including application timing, canopy volume, fruit load, etc. Refer to labeled uses in apple, pear and cherry for additional guidance
