SEVERAL IMPORTANT PRUNE/PLUM ROOTSTOCKS ARE KNOWN FOR SUCKERING. CURRENT PRIMARY MANAGEMENT TACTICS FOR SUCKER CONTROL INCLUDES PHYSICAL APPROACHES SUCH AS HAND REMOVAL OR REPEATED APPLICATIONS OF CONTACT HERBICIDE SUCH AS PARAQUAT. LOW RATES OF NAA CAN SUPPRESS SUCKER GROWTH AND REDUCE USE OF MORE DAMAGING HERBICIDES SUCH AS PARAQUAT AND 2,4-D. 1/23;

| Reasons for need: |
SUCKER CONTROL; SUCKER CONTROL; NEED FOR SYSTEMIC LONG LASTING PRODUCT TO SUPPRESS SUCKER GROWTH AND REDUCE NUMBER OF CONTACT HERBICIDE SPRAYS AND HAND LABOR FOR ROOTSTOCK SUCKERS, BASAL TRUNK SPROUTS. 1/23;

| PCR Use Pattern: |
APPLY TO BASAL SPROUTS AND ROOT SUCKERS PRIOR TO FRUIT SET, 1% PRODUCT; DIRECTED SPRAY TO LOWER TREE TRUNKS AND IMMEDIATE SURROUNDING AREA; APPLY AFTER DORMANT TREES RESUME GROWTH AND SUCKERS BECOME VISIBLE IN THE SPRING. RE-TREATMENT INTERVAL OF 60 DAYS AND PHI OF 45 DAYS. USE THE TRE-HOLD SPROUT INHIBITOR A-112 PRODUCT; MAKE 2 SOIL DIRECTED BASAL APPLIC OF A 1% AI SOLUTION, V/V, 28-DAY INTERVAL; APPLY AS A DIRECTED SPRAY TO THE LOWER TREE TRUNKS AND IMMEDIATE SURROUNDING AREA; MAKE 1ST APPPLIC WHEN SUCKERS ARE LESS THAN 12 INCH; APPLY IN A DILUTE VOLUME OF UP TO 44 GPA, USING A NOZZLE THAT GENERATES COARSE DROPLETS, AND DIRECT THE SPRAY TO THE BASE OF THE TREES; IF NEEDED RE-APPLY IN 60 DAY 1/23;
