SPINACH (04-16A = LEAFY GREENS SUBGROUP) UNDER EVALUATION (06)
Reasons for need: WEEDS; NEED IS FOR REDUCING THE PHI FROM 21 TO 10-14 DAYS TO ALLOW ITS USE FOR CLIPPED SPINACH (FRESH MARKET) WHICH HAS A SHORTER CROP CYCLE THAN FREEZER SPINACH; PER FL ME-TOO REQUEST, WITH THE RISING POPULARITY OF BABY LEAF SPINACH A SHORTER 10-14 DAY PHI IS NEEDED
Efficacy/Crop Safety (E/CS) Data Required:
E/CS Research Comments:
Comments: KEY EXPORT MARKETS NOT NOTED:06/18; EPA GREEN:09/18; ADDED BELCHIM CROP PROTECTION AS A MFG, AS THEY HAVE THE SPIN-AID PRODUCT LABELED FOR USE ON SPINACH (ON PROCESSING AND SEED SPINACH) AND RED BEETS:10/18; BELCHIM STILL NEEDS SOME TYPE OF SUPPORT FROM BAYER TO CONSIDER THIS BEING RESEARCHABLE:05/19; BAYER'S CONCERN IS THAT THERE IS A NEED TO STAY UNDER A CERTAIN VOLUME OF SALES (LOW-VOLUME WAIVER), BUT THAT INCREASED SALES OF BABY SPINACH MAY BE AN ISSUE:06/20; EPA GREEN: 08/20, 08/21

Smith, Dr. Richard 16-CA-DMP RECD 4549.pdf THREE TRIALS. SPIN-AID AT 1 PT/A POST APPLIED IN THE EVENING REDUCED WEED PRESSURE BY 53-95% OVER THE STANDARD PRE TREATMENT, BUT REDUCED YIELD BY 3-13 %.
Fennimore, S. 13-CA-DMP RECD 4652.pdf 0.09, 0.18 AND 0.27 KG AI/HA POST FOLLOWING CYCLOATE PRE; GOOD CROP TOLERANCE OF 2 VARIETIES TESTED; WEED CONTROL AT THE HIGHEST RATE, AND YIELD AT ALL RATES COMPARABLE TO HANDWEEDING FOLLOWING CYCLOATE PRE.
Fennimore, S. 14-CA-DMP RECD 4653.pdf GREENHOUSE AND FIELD STUDIES IN 2013-2014 USING 0.55 KG AI/HA POST TO CHECK VARIETAL SENSITIVITY AND EFFECT OF LIGHT ON CROP TOLERANCE TO PHENMEDIPHAM. RESULTS SHOWED DIFFERENCES IN TOLERANCE BETWEEN VARIETIES, AND THAT LIGHT INTENSITY IS A MAJOR FACTOR THAT AFFECTS TOLERANCE LEVELS.
Fennimore, S. 14-CA-DMP RECD 4654.pdf GREENHOUSE AND FIELD STUDIES TO CHECK VARIETAL SENSITIVITY AND EFFECT OF LIGHT ON CROP TOLERANCE TO PHENMEDIPHAM. RESULTS SHOWED DIFFERENCES IN TOLERANCE BETWEEN VARIETIES, AND THAT APPLICATION IN THE EVENING WAS SAFER THAN MORNING. RESULTS OF FIELD STUDIES SHOWED 0.09 AND 0.18 KG AI/HA POST AT 2-LF STAGE FOLLOWING CYCLOATE PRE PROVIDING GOOD CROP TOLERANCE OF 2 VARIETIES TESTED, WEED CONTROL AND YIELD COMPARABLE TO HANDWEEDING FOLLOWING CYCLOATE PRE.
