<p>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." <br>

<div>I hope you meant a Low volume of water. High volume = slow
drying = russeting. This is very easy to demonstrate. We do it
as a "control" in plots. We always have copper induced russeting
at 500 L/ha and none at 225 L/ha. <br>

<p>Kerik Cox at Cornell has done trials with this combination
for cedar apple rust, summer fungal diseases, and fireblight
and has had good results.
<br>
</p>
<p>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. <br>
</p>
<p>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.<br>
