SLIDE CONTENTS
  1. Influence of Cadre on Georgia Green Yield and Seed Germination Eric P. Prostko and Tim L. Grey Department of Crop & Soil Sciences University of Georgia APRES 2005
  2. Cadre (imazapic) BASF product labeled for peanut in 1996 postemergence nutsedges broadleaf small grasses very popular 64% in GA $13-18/A rotation restrictions
  3. Peanut Varieties and Cadre
  4. Georgia Green in Georgia Source: UGA Peanut Production Surveys
  5. Peanut Stand Issues TSWV Florida MDR98 DP-1 GA-01R Do herbicides influence seed germination?
  6. Objectives Influence of Cadre on Georgia Green…… Yield Seed size germination
  7. Materials and Methods Small plot techniques (4 reps) Planting date: May 13, 2004 twin rows Cadre @ 1.44 ozs/A + Agrioil @ 1% v/v 8, 14, 22, 27, 34, 41, 47, 57 DAP Weed-free conditions Strongarm + Prowl hand-weeded 1000 lbs/A Gypsum on June 23, 2004
  8. Stages of Growth
  9. Seed Collection 100 pods after digging but before combine Stored at room temperature for 36 days hand-shelled weight of 100 seed placed in cold storage (320F) for 18 days germination test at 770F Seed stored at room temperature (20 days) Germination test at 680F
  10. Germination Tests Growth chamber Dark conditions Two constant temperatures 680 and 770 F 2 runs Petri dishes 2 layers of filter paper 10 seeds/dish 10 mls of tap water 7 days
  11. Results
  12. Georgia Green Yield Response to Cadre (1.44 ozs/A + Agrioil @ 1% v/v) P = 0.4515 CV = 11.21 PE-11-04 Attapulgus
  13. Influence of Cadre on Georgia Green Seed Size (1.44 ozs/A + Agrioil @ 1% v/v) P = 0.0921 CV = 3.81 PE-11-04 Attapulgus
  14. Influence of Cadre on Georgia Green Seed Germination (770F- 7 days) (1.44 ozs/A + Agrioil @ 1% v/v) P = 0.08 CV = 5.68 PE-11-04 Attapulgus (average of 2 runs) 54 day old seed
  15. Influence of Cadre on Georgia Green Seed Germination (680F - 7 days) (1.44 ozs/A + Agrioil @ 1% v/v) P = 0.1689 CV = 9.2 PE-11-04 Attapulgus (average of 2 runs) 74 day old seed
  16. Summary Cadre had no effect on ….. Yield Seed size seed germination
  17. 2005 Research Cadre @ 1.44 ozs/A + COC @ 1% v/v 30 and 45 DAP 2,4-DB @ 1.1 pts/A + COC @ 1% v/v 75 and 95 DAP 3 peanut varieties GA Green, C99-R, GA – 01R 2 locations in Georgia National Peanut Board Funding
