[Apple-Crop] Cueva/Double Nickel

[Two Onion Farm]

I'm certainly not an expert!  The cueva label says "May cause russeting 
of susceptible apple varieties. Do not exceed the 1.0 gallon of product/ 
100 gallons water use rate."  When Kerik started me on this program, he 
said "we never get fruit finish injury. However, depending on your spray 
volume, you could have a different experience. We use 100 gal/A in our 
block."
