<div class="moz-cite-prefix">Hi Vincent, <br>
<br>
We've found that concentration is potentially more damaging with
copper than higher volumes as the both 50gal and 100gal get the
same amount of copper. It's like taking powdered aspirin with half
the recommended amount of water. Also, many labels in the US
actually require that certain products be applied in a minimum of
100 gal/A. If were potentially injurious to apply at 100 gal/A, I
assure you that no company would include any such statements on
label. Actually, they would, without a doubt, put statements
saying that the product should not be applied at 100 gal/A or
injury would occur. Excess water seems to just roll off the trees
in our experiments. <br>
<br>
Best,<br>
Kerik<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>
