What Can You Tell Me About APSA 80?

Mar 17, 2011

Question:  I have been asked to try APSA 80 Adjuvant in my corn and alfalfa.  Before I do, I wanted to do some research. The info on the web is conflicting. What can you tell me about this product? (2.5 gal = $100.00: 30 gal drum = $1,049.00)

Answer:  APSA80 is All Purpose Spray Adjuvant formula that includes 80% active ingredients. The adjuvant is a wetting agent that lowers the surface tension of water, which allows spray droplets to spread out on the leaf surface. We have not tested this product. I would treat it like any other adjuvant and price it out according to the recommended use rate.
