Crop Management - Jim Reiss, Precision Lab - Tank Mixing for Success
- 1. Tank Mixing for Success Jim Reiss Vice President – Agricultural Chemistries Precision Laboratories, Inc.
- 2. • 50 Year-Old Company • Located in Waukegan, IL • Innovative Adjuvants, Seed Enhancements and Foliar Nutrition Technologies • Backed by University & Independent Research
- 3. Resistance is GROWING 9 weeds in 20+ states are resistant to glyphosate • Over 7 million acres of row crops infested in 2010 • 38 million by 2013 (spread by pollen 20-30 miles) Stacked resistance not just for crops • Triple-stacked & Quad-stacked resistance in weeds • ALS inhibitors, glyphosate, PPO inhibitors and triazines (S. IL) Trends support continued growth in resistance • Larger farms with less tillage • Post applications of glyphosate year after year 3
- 10. Weed Seed Production and Length of Seed Survival # of Seeds per Length of Seed Weed Plant Survival (yrs) Nightshade 178,000 10 - 20 G. Ragweed 60,000 5-8 Lambsquarters 72,000 3-9 Short - Immediate Marestail 200,000 + germination Waterhemp 400,000 + 3-5 Palmer Amaranth 500,000 + 3-5 Weed Science, principles and practices; Applied Weed Science, second edition; Weed Ecology, second edition; Weed Technology
- 11. Tank Mixing is BACK PPI and PRE treatments growing • Tank mixing with UAN and / or ATS • New SC formulations not be as stable as Flowables More post emerge tank mixing • PREs can’t handle all our problems (volunteer corn) • More use of foliar feeding program • More fungicides & / or insecticides More tank mixes = more problems… UNLESS 11
- 12. Preparing to Win Objectives • Review “Best Mixing” Practices • Review impact of water quality on pesticides and mixing order • Determine best mixing sequence & tools to avoid problems • Answer your questions
- 13. Avoiding Mixing & Clean-out Nightmares • Mixing Technique • Mixing Order • Making Clean-out Easier
- 14. Just because you can… DOESN’T mean you should!
- 15. Mixing Vats & Inductors are Not Like Las Vegas • What happens here, DOESN’T just stay here… • It goes into the sprayer… • And, if your lucky it goes onto the field
- 16. Inductors & Mixing Vats Bad Things Start Here • In the absence of sufficient water, mixing order doesn’t matter • Sometimes a little water is worse than no water • Depending on solution pH some products may not dissolve, others could salt out
- 17. Roundup® WeatherMAX™ plus Water Conditioning Agent SALTED OUT in mixing vat
- 18. Inductors & Mixing Vats The Solution • Conduct compatibility tests to make sure • Mix in a minimum of 15-20% of intended spray volume • Follow the appropriate mixing order & WAIT • Or, open the valve and leave it open
- 19. Mixing Order & Water Quality • pH can affect CP product solubility & uptake • pH can affect CP half-life • pH levels should affect the mixing order
- 20. Mixing Order & Water Quality • What’s the pH of your water?

- 22. Mixing Order & Water Quality pH Scale 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Compatibility Agents Natural pH of well water
- 23. Mixing Order & Water Quality pH Scale 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Compatibility Best pH to solubilize most SUs Agents Natural pH of well water
- 24. Mixing Order & Water Quality pH Scale 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Best pH to solubilize most SUs Natural pH of well water Water Conditioners alone
- 25. Mixing Order & Water Quality pH Scale 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Glyphosate buffer Best pH to solubilize most SUs Natural pH of well water Water Conditioners alone
- 26. Mixing Order & Water Quality Do you have to add water conditioners to the spray solution before glyphosate?

- 28. Out of Mixing Order… Out of Luck!
- 29. Best Mixing Sequence Fill tank with at least ½ of intended finished spray volume and with agitation running, add: • Compatibility agents & defoamers • Add Sulfonylurea herbicides before reducing pH (or pre slurry and add) • Dry Products – Ammonium sulfate – Dry drift retardants – WP, DF, WDG, SP • Liquids – Liquid drift retardants – Flowables (F) or Liquid Flowables (FL) – Micro encapsulated (ME) and Suspension Concentrates (SC) – Emulsifiable concentrates (EC) – Solutions (L, C, LC) – Crop Oils, MSO, HSOC, NIS – Water Conditioners
