On the topic of copper: you don't need to spend extra for Cueva. Use of standard oxychloride at a low dose is just as good in most instances.

We started using the combination in our organic orchard last year and did not see any problems with fruit russeting. Kerik did caution me to use a high volume of water to avoid toxicity from the copper (100 gallons per acre vs our normal 50 in our high density orchard). We have used 2 qts/acre Cueva + 2 lbs/acre 2ble nickel. Kerik also suggested that the 2ble nickel might be unnecessary and that cueva alone might be sufficient, but that may be theoretical at this point. The 2ble nickel does add a lot of cost.

Is anyone aware of further research regarding this combination esp as to regards to crop safety and efficacy ?
